+# GearBox
+
+## What This Is
+
+A web-based gear management and purchase planning app. Users catalog their gear collections (bikepacking, sim racing, or any hobby), track weight, price, and source details, search and filter by name or category, and use planning threads to research and compare new purchases with status tracking. Named setups let users compose loadouts with weight classification (base/worn/consumable), donut chart visualization, and live totals in selectable units. Built as a single-user app with a clean, minimalist interface.
+
+## Core Value
+
+Make it effortless to manage gear and plan new purchases — see how a potential buy affects your total setup weight and cost before committing.
+
+## Requirements
+
+### Validated
+
+- ✓ Gear collection with item CRUD (name, weight, price, category, notes, product link) — v1.0
+- ✓ Image uploads for gear items — v1.0
+- ✓ User-defined categories with automatic weight/cost totals — v1.0
+- ✓ Planning threads for purchase research with candidate products — v1.0
+- ✓ Thread resolution: pick a winner, it moves to collection — v1.0
+- ✓ Named setups (loadouts) composed from collection items — v1.0
+- ✓ Live weight and cost totals per setup — v1.0
+- ✓ Dashboard home page with summary cards — v1.0
+- ✓ Onboarding wizard for first-time setup — v1.0
+- ✓ Thread creation with category assignment via modal dialog — v1.1
+- ✓ Planning tab with educational empty state and pill tab navigation — v1.1
+- ✓ Image display on item detail views and gear cards with placeholders — v1.1
+- ✓ Hero image upload area with preview and click-to-upload — v1.1
+- ✓ Lucide icon picker for categories (119 curated icons, 8 groups) — v1.1
+- ✓ Automatic emoji-to-Lucide icon migration for existing categories — v1.1
+- ✓ Search items by name with instant filtering — v1.2
+- ✓ Filter collection items by category with icon-aware dropdown — v1.2
+- ✓ Combined text search with category filter and result count — v1.2
+- ✓ One-action filter clear — v1.2
+- ✓ Weight unit selection (g, oz, lb, kg) with persistence — v1.2
+- ✓ All weight displays respect selected unit across entire app — v1.2
+- ✓ Per-setup item classification (base weight, worn, consumable) — v1.2
+- ✓ Setup weight subtotals by classification — v1.2
+- ✓ Donut chart visualization with category/classification toggle — v1.2
+- ✓ Chart hover tooltips with weight and percentage — v1.2
+- ✓ Candidate status tracking (researching/ordered/arrived) — v1.2
+- ✓ Planning category filter with Lucide icons — v1.2
+
+### Active
+
+(No active milestone — use `/gsd:new-milestone` to start next)
+
+### Future
+
+- [ ] Side-by-side candidate comparison on weight and price
+- [ ] Candidate ranking/prioritization within threads
+- [ ] Impact preview: how a candidate affects setup weight/cost
+- [ ] CSV import/export for gear collections
+- [ ] Multi-user accounts with authentication
+- [ ] Collection sharing and social features (public profiles, shared setups)
+- [ ] Auto-fill product information (price, weight, images) from external sources
+
+### Out of Scope
+
+- Custom comparison parameters — complexity trap, weight/price covers 80% of cases
+- Mobile native app — web-first, responsive design sufficient
+- Price tracking / deal alerts — requires scraping, fragile
+- Barcode scanning / product database — requires external database
+- Community gear database — requires moderation, accounts
+- Real-time weather integration — only outdoor-specific, GearBox is hobby-agnostic
+
+## Context
+
+Shipped v1.2 with 7,310 LOC TypeScript.
+Tech stack: React 19, Hono, Drizzle ORM, SQLite, TanStack Router/Query, Tailwind CSS v4, Lucide React, Recharts, all on Bun.
+Primary use case is bikepacking gear but data model is hobby-agnostic.
+Replaces spreadsheet-based gear tracking workflow.
+121 tests (service-level and route-level integration).
+
+## Constraints
+
+- **Runtime**: Bun — used as package manager and runtime
+- **Design**: Light, airy, minimalist — white/light backgrounds, lots of whitespace, no visual clutter
+- **Navigation**: Dashboard-based home page, not sidebar or top-nav tabs
+- **Scope**: No auth, single user for v1
+
+## Key Decisions
+
+| Decision | Rationale | Outcome |
+|----------|-----------|---------|
+| No auth for v1 | Single user, simplicity first | ✓ Good |
+| Generic data model | Support any hobby, not just bikepacking | ✓ Good |
+| Dashboard navigation | Clean entry point, not persistent nav | ✓ Good |
+| Bun runtime | User preference | ✓ Good |
+| Service layer with DI | Accept db as first param for testability | ✓ Good |
+| Hono context variables for DB | Enables in-memory SQLite integration tests | ✓ Good |
+| Prices stored as cents | Avoids float rounding issues | ✓ Good |
+| Vite proxy dev setup | Required by TanStack Router plugin | ✓ Good |
+| drizzle-kit needs better-sqlite3 | bun:sqlite not supported by CLI | ✓ Good |
+| Tab navigation via URL params | Shareable URLs between gear/planning | ✓ Good |
+| Setup item sync: delete-all + re-insert | Simpler than diffing, atomic in transaction | ✓ Good |
+| Onboarding state in SQLite settings | Source of truth in DB, not Zustand | ✓ Good |
+| Stay with SQLite | Single-user app, no need for Postgres complexity | ✓ Good |
+| Lucide Icons for categories | Best outdoor/gear icon coverage, tree-shakeable, clean style | ✓ Good |
+| categoryId on threads (NOT NULL FK) | Every thread belongs to a category | ✓ Good |
+| Modal dialog for thread creation | Cleaner UX, supports category selection | ✓ Good |
+| Hero image area at top of forms | Image-first UX, 4:3 aspect ratio consistent with cards | ✓ Good |
+| Emoji-to-icon automatic migration | One-time schema rename + data conversion via Drizzle migration | ✓ Good |
+| ALTER TABLE RENAME COLUMN for SQLite | Simpler than table recreation for column rename | ✓ Good |
+| Weight conversion precision: g=0dp, oz=1dp, lb=2dp, kg=2dp | Matches common usage conventions | ✓ Good |
+| Unit toggle in TotalsBar (not settings page) | Visible, quick access for frequent switching | ✓ Good |
+| CategoryFilterDropdown separate from CategoryPicker | Filter vs form concerns are different | ✓ Good |
+| No debounce on search input | Collection under 1000 items, instant feedback | ✓ Good |
+| StatusBadge popup with click-outside dismiss | Consistent with CategoryPicker pattern | ✓ Good |
+| Classification on setupItems join table | Same item can have different roles per setup | ✓ Good |
+| Click-to-cycle for ClassificationBadge | Only 3 values, simpler than popup | ✓ Good |
+| Classification-preserving sync via Map | Save metadata before delete, restore after re-insert | ✓ Good |
+| Recharts for charting | Mature React chart library, composable API | ✓ Good |

+
+## Milestone: v1.0 — MVP
+
+**Shipped:** 2026-03-15
+**Phases:** 3 | **Plans:** 10 | **Commits:** 53
+
+### What Was Built
+- Full gear collection with item CRUD, categories, weight/cost totals, and image uploads
+- Planning threads with candidate comparison and thread resolution into collection
+- Named setups (loadouts) composed from collection items with live totals
+- Dashboard home page with summary cards
+- Onboarding wizard for first-time user experience
+- Service-level and route-level integration tests
+
+### What Worked
+- Coarse 3-phase structure kept momentum high — no planning overhead between tiny phases
+- TDD approach for backend (service tests first) caught issues early and made frontend integration smooth
+- Service layer with DI (db as first param) made testing trivial with in-memory SQLite
+- Visual verification checkpoints at end of each phase caught UI issues before moving on
+- Bun + Vite + Hono stack had zero friction — everything worked together cleanly
+
+### What Was Inefficient
+- Verification plans (XX-03) were mostly rubber-stamp auto-approvals in yolo mode — could skip for v2
+- Some ROADMAP plan checkboxes never got checked off (cosmetic, didn't affect tracking)
+- Performance metrics in STATE.md had stale placeholder data alongside real data
+
+### Patterns Established
+- Service functions: `(db, params) => result` with production db default
+- Route-level integration tests using Hono context variables for db injection
+- Prices in cents everywhere, display conversion in UI only
+- Tab navigation via URL search params for shareability
+- Atomic sync pattern: delete-all + re-insert in transaction
+
+### Key Lessons
+1. Coarse granularity (3 phases for an MVP) is the right call for a greenfield app — avoids over-planning
+2. The Vite proxy pattern is required when using TanStack Router plugin — can't do Bun fullstack serving
+3. drizzle-kit needs better-sqlite3 even on Bun — can't use bun:sqlite for migrations
+4. Onboarding state belongs in the database (settings table), not in client-side stores
+
+### Cost Observations
+- Model mix: quality profile throughout
+- Sessions: ~10 plan executions across 2 days
+- Notable: Most plans completed in 3-5 minutes, total wall time under 1 hour
+
+---
+
+## Milestone: v1.1 — Fixes & Polish
+
+**Shipped:** 2026-03-15
+**Phases:** 3 | **Plans:** 7 | **Files changed:** 65
+
+### What Was Built
+- Fixed threads table and thread creation with categoryId support and modal dialog
+- Overhauled planning tab with educational empty state, pill tabs, and category filter
+- Fixed image display bug (Zod schema missing imageFilename)
+- Redesigned image upload as 4:3 hero preview area with placeholders on all cards
+- Migrated categories from emoji to Lucide icons with 119-icon curated picker
+- Built IconPicker with search, 8 group tabs, and portal popover
+
+### What Worked
+- Auto-advance pipeline (discuss → plan → execute) completed both phases end-to-end without manual intervention
+- Wave-based parallel execution in Phase 6 — plans 06-02 and 06-03 ran concurrently with no conflicts
+- Executor auto-fix deviations handled cascading renames gracefully (emoji→icon required touching hooks/routes beyond plan scope)
+- Context discussion upfront captured clear decisions — no ambiguity during execution
+- Verifier caught real issues (Zod schema root cause) and confirmed all must-haves
+
+### What Was Inefficient
+- Schema renames cascade through many files (12 in 06-01) — executors had to auto-fix downstream references not in the plan
+- Some ROADMAP.md plan checkboxes remained unchecked despite plans completing (cosmetic tracking drift)
+- Phase 5 executor installed inline SVGs for ImageUpload icons, then Phase 6 added lucide-react anyway — could have coordinated
+
+### Patterns Established
+- Portal-based popover pattern: reused from EmojiPicker → IconPicker (click-outside, escape, portal rendering)
+- LucideIcon dynamic lookup component: `icons[name]` from lucide-react for runtime icon resolution
+- Curated icon data file pattern: static data organized by groups for picker UIs
+- Hero image area: full-width 4:3 preview at top of forms with placeholder/upload/preview states
+
+### Key Lessons
+1. Zod validation middleware silently strips unknown fields — always add new schema fields to Zod schemas, not just DB schema
+2. Auto-fix deviations are a feature, not a bug — executors that fix cascading renames save manual replanning
+3. Auto-advance pipeline works well for straightforward phases — interactive discussion ensures decisions are clear before autonomous execution
+4. Parallel Wave 2 execution with no file overlap is safe and efficient
+
+### Cost Observations
+- Model mix: opus for execution, sonnet for verification/checking
+- Sessions: 1 continuous auto-advance pipeline for both phases
+- Notable: Full milestone (discuss + plan + execute × 2 phases) completed in a single session
+
+---
+
+## Milestone: v1.2 — Collection Power-Ups
+
+**Shipped:** 2026-03-16
+**Phases:** 3 | **Plans:** 6 | **Files changed:** 66
+
+### What Was Built
+- Weight unit conversion (g/oz/lb/kg) with segmented toggle wired across all weight display call sites
+- Candidate status tracking (researching/ordered/arrived) with clickable StatusBadge popup
+- Sticky search/filter toolbar with text search and icon-aware CategoryFilterDropdown
+- Per-setup item classification (base/worn/consumable) with click-to-cycle ClassificationBadge
+- Recharts donut chart with category/classification toggle and hover tooltips
+- Classification-preserving sync that maintains metadata across atomic setup item re-sync
+
+### What Worked
+- Coarse 3-phase structure again — 19 requirements compressed into 3 phases with clear dependency ordering
+- TDD red/green commits for schema migrations (status, classification) caught edge cases early
+- Vertical slice pattern (schema → service → tests → API → UI in one plan) kept each deliverable self-contained
+- Click-outside dismiss pattern established in v1.1 was reused cleanly in StatusBadge and CategoryFilterDropdown
+- All 6 plans executed with zero deviations from plan — evidence of mature planning process
+
+### What Was Inefficient
+- Some ROADMAP.md plan checkboxes remained unchecked despite summaries existing (persistent cosmetic drift)
+- Recharts v3 Cell component is deprecated for v4 — will need migration eventually
+- Phase 8 bundled search/filter with candidate status (different concerns) — could have been separate phases for cleaner scope
+
+### Patterns Established
+- Click-to-cycle badge: for small enums (3 values), direct click cycling is simpler than popup menus
+- Join table metadata preservation: save metadata to Map before atomic sync, restore after re-insert
+- CategoryFilterDropdown: reusable filter dropdown (separate from form-based CategoryPicker)
+- Chart data transformation: group items by key, sum weights, compute percentages, filter zeroes
+- apiPatch helper: PATCH method now available in client API library for partial updates
+
+### Key Lessons
+1. Classification belongs on join tables (setupItems), not entity tables (items) — same item has different roles in different contexts
+2. Vertical slice delivery (schema → service → test → API → UI) is the optimal plan structure for feature additions
+3. Search complexity should match data scale — no debounce needed for <1000 items
+4. Recharts composable API (PieChart + Pie + Cell + Tooltip + Label) gives fine-grained chart control with minimal wrapper code
+
+### Cost Observations
+- Model mix: quality profile throughout (opus for execution)
+- Sessions: 3 continuous auto-advance sessions (one per phase)
+- Notable: All plans completed with zero deviations, execution faster than v1.0/v1.1
+
+---
+
+## Cross-Milestone Trends
+
+### Process Evolution
+
+| Milestone | Commits | Phases | Key Change |
+|-----------|---------|--------|------------|
+| v1.0 | 53 | 3 | Initial build, coarse granularity, TDD backend |
+| v1.1 | ~30 | 3 | Auto-advance pipeline, parallel wave execution, auto-fix deviations |
+| v1.2 | 25 | 3 | Zero-deviation execution, vertical slice pattern, join table metadata |
+
+### Cumulative Quality
+
+| Milestone | LOC | Files | Tests |
+|-----------|-----|-------|-------|
+| v1.0 | 5,742 | 114 | Service + route integration |
+| v1.1 | 6,134 | ~130 | Service + route integration (updated for icon schema) |
+| v1.2 | 7,310 | ~150 | 121 tests (service + route + classification) |
+
+### Top Lessons (Verified Across Milestones)
+
+1. Coarse phases with TDD backend → smooth frontend integration
+2. Service DI pattern enables fast, reliable testing without mocks
+3. Always update Zod schemas alongside DB schema — middleware silently strips unvalidated fields
+4. Auto-advance pipeline (discuss → plan → execute) works well for clear-scope phases
+5. Vertical slice delivery (schema → service → test → API → UI) is optimal for feature additions
+6. Join table metadata (not entity table) when same entity plays different roles in different contexts

+# Roadmap: GearBox
+
+## Overview
+
+GearBox delivers a gear management and purchase planning web app in three phases. Phase 1 establishes the foundation and builds the complete gear collection feature — the core entity everything else depends on. Phase 2 adds planning threads, the product's differentiator, enabling structured purchase research with candidate comparison and thread resolution into the collection. Phase 3 completes the app with named setups (loadouts composed from collection items) and the dashboard home page that ties everything together.
+
+## Phases
+
+**Phase Numbering:**
+- Integer phases (1, 2, 3): Planned milestone work
+- Decimal phases (2.1, 2.2): Urgent insertions (marked with INSERTED)
+
+Decimal phases appear between their surrounding integers in numeric order.
+
+- [x] **Phase 1: Foundation and Collection** - Project scaffolding, data model, and complete gear item CRUD with categories and totals (completed 2026-03-14)
+- [x] **Phase 2: Planning Threads** - Purchase research workflow with candidates, comparison, and thread resolution (completed 2026-03-15)
+- [x] **Phase 3: Setups and Dashboard** - Named loadouts from collection items and dashboard home page (completed 2026-03-15)
+
+## Phase Details
+
+### Phase 1: Foundation and Collection
+**Goal**: Users can catalog their gear collection with full item details, organize by category, and see aggregate weight and cost totals
+**Depends on**: Nothing (first phase)
+**Requirements**: COLL-01, COLL-02, COLL-03, COLL-04
+**Success Criteria** (what must be TRUE):
+  1. User can add a gear item with name, weight, price, category, notes, and product link and see it in their collection
+  2. User can edit any field on an existing item and delete items they no longer want
+  3. User can create, rename, and delete categories, and every item belongs to a user-defined category
+  4. User can see automatic weight and cost totals per category and for the entire collection
+  5. The app runs as a single Bun process with SQLite storage and serves a clean, minimalist UI
+**Plans:** 4/4 plans complete
+
+Plans:
+- [ ] 01-01-PLAN.md — Project scaffolding, DB schema, shared schemas, and test infrastructure
+- [ ] 01-02-PLAN.md — Backend API: item CRUD, category CRUD, totals, image upload with tests
+- [ ] 01-03-PLAN.md — Frontend collection UI: card grid, slide-out panel, category picker, totals bar
+- [ ] 01-04-PLAN.md — Onboarding wizard and visual verification checkpoint
+
+### Phase 2: Planning Threads
+**Goal**: Users can research potential purchases through planning threads — adding candidates, comparing them, and resolving a thread by picking a winner that moves into their collection
+**Depends on**: Phase 1
+**Requirements**: THRD-01, THRD-02, THRD-03, THRD-04
+**Success Criteria** (what must be TRUE):
+  1. User can create a planning thread with a descriptive name and see it in a threads list
+  2. User can add candidate products to a thread with weight, price, notes, and product link
+  3. User can edit and remove candidates from an active thread
+  4. User can resolve a thread by selecting a winning candidate, which automatically creates a new item in their collection and archives the thread
+**Plans:** 3/3 plans complete
+
+Plans:
+- [ ] 02-01-PLAN.md — Backend API: thread/candidate CRUD, resolution transaction, with TDD
+- [ ] 02-02-PLAN.md — Frontend: tab navigation, thread list, candidate UI, resolution flow
+- [ ] 02-03-PLAN.md — Visual verification checkpoint
+
+### Phase 3: Setups and Dashboard
+**Goal**: Users can compose named loadouts from their collection items with live totals, and navigate the app through a dashboard home page
+**Depends on**: Phase 1, Phase 2
+**Requirements**: SETP-01, SETP-02, SETP-03, DASH-01
+**Success Criteria** (what must be TRUE):
+  1. User can create a named setup (e.g. "Summer Bikepacking") and see it in a setups list
+  2. User can add and remove collection items from a setup
+  3. User can see total weight and cost for a setup, computed live from current item data
+  4. User sees a dashboard home page with cards linking to their collection, active threads, and setups
+**Plans:** 3/3 plans complete
+
+Plans:
+- [ ] 03-01-PLAN.md — Backend TDD: setup schema, service, routes, and tests with junction table
+- [ ] 03-02-PLAN.md — Frontend: navigation restructure, dashboard, setup UI, and item picker
+- [ ] 03-03-PLAN.md — Visual verification checkpoint

+<objective>
+Scaffold the GearBox project from scratch: install all dependencies, configure Vite + Hono + Tailwind + TanStack Router + Drizzle, create the database schema, shared validation schemas, and test infrastructure.
+
+Purpose: Establish the complete foundation that all subsequent plans build on. Nothing can be built without the project scaffold, DB schema, and shared types.
+Output: A running dev environment with two servers (Vite frontend on 5173, Hono backend on 3000), database with migrations applied, and a test harness ready for service tests.

+       - Core backend: `bun add hono @hono/zod-validator drizzle-orm`
+       - Styling: `bun add tailwindcss @tailwindcss/vite`

+    3. Initialize Biome: `bunx @biomejs/biome init`
+
+    4. Create `tsconfig.json` with target ESNext, module ESNext, moduleResolution bundler, jsx react-jsx, strict true, paths "@/*" mapping to "./src/*", types ["bun-types"].
+
+    5. Create `vite.config.ts` following RESEARCH.md Pattern 1 exactly. Plugins in order: tanstackRouter (target react, autoCodeSplitting true), react(), tailwindcss(). Proxy /api and /uploads to http://localhost:3000. Build output to dist/client.
+
+    6. Create `drizzle.config.ts` per RESEARCH.md example (dialect sqlite, schema ./src/db/schema.ts, out ./drizzle, url gearbox.db).
+
+    7. Create `index.html` as Vite SPA entry point with div#root and script src /src/client/main.tsx.
+
+    8. Create `src/client/app.css` with Tailwind v4 import: @import "tailwindcss";
+
+    9. Create `src/client/main.tsx` with React 19 createRoot, TanStack Router provider, and TanStack Query provider.
+
+    10. Create `src/client/routes/__root.tsx` as root layout with Outlet. Import app.css here.
+
+    11. Create `src/client/routes/index.tsx` as default route with placeholder text "GearBox Collection".
+
+    12. Create `src/server/index.ts` following RESEARCH.md Pattern 1: Hono app, health check at /api/health, static file serving for /uploads/*, production static serving for Vite build, export default { port: 3000, fetch: app.fetch }.
+
+    13. Add scripts to package.json: "dev:client": "vite", "dev:server": "bun --hot src/server/index.ts", "build": "vite build", "db:generate": "bunx drizzle-kit generate", "db:push": "bunx drizzle-kit push", "test": "bun test", "lint": "bunx @biomejs/biome check ."

+       - items table: id (integer PK autoIncrement), name (text notNull), weightGrams (real nullable), priceCents (integer nullable), categoryId (integer notNull references categories.id), notes (text nullable), productUrl (text nullable), imageFilename (text nullable), createdAt (integer timestamp), updatedAt (integer timestamp)
+       - settings table: key (text PK), value (text notNull) for onboarding flag
+       - Export all tables
+
+    2. Create `src/db/index.ts` per RESEARCH.md Database Connection Singleton: bun:sqlite Database, PRAGMA journal_mode WAL, PRAGMA foreign_keys ON, export drizzle instance with schema.
+
+    3. Create `src/db/seed.ts`: seedDefaults() inserts Uncategorized category with box emoji if no categories exist. Export the function.
+
+    4. Create `src/shared/schemas.ts` per RESEARCH.md Shared Zod Schemas: createItemSchema (name required, weightGrams optional nonneg, priceCents optional int nonneg, categoryId required int positive, notes optional, productUrl optional url-or-empty), updateItemSchema (partial + id), createCategorySchema (name required, emoji with default), updateCategorySchema (id required, name optional, emoji optional). Export all.
+
+    5. Create `src/shared/types.ts`: Infer TS types from Zod schemas (CreateItem, UpdateItem, CreateCategory, UpdateCategory) and from Drizzle schema (Item, Category using $inferSelect). Export all.
+
+    6. Create `tests/helpers/db.ts`: createTestDb() function that creates in-memory SQLite, enables foreign keys, applies schema via raw SQL CREATE TABLE statements matching the Drizzle schema, seeds Uncategorized category, returns drizzle instance. This avoids needing migration files for tests.
+
+    7. Run `bunx drizzle-kit push` to apply schema to gearbox.db.

+# Phase 1 Plan 01: Project Scaffolding Summary
+
+**Full-stack scaffold with Vite 8 + Hono on Bun, Drizzle SQLite schema for items/categories, shared Zod validation, and in-memory test infrastructure**
+
+## Performance
+
+- **Duration:** 4 min
+- **Started:** 2026-03-14T21:31:03Z
+- **Completed:** 2026-03-14T21:35:06Z
+- **Tasks:** 2
+- **Files modified:** 15
+
+## Accomplishments
+
+- Complete project scaffold with all dependencies installed and Vite build passing
+- SQLite database schema with items, categories, and settings tables via Drizzle ORM
+- Shared Zod schemas for item and category validation used by both client and server
+- In-memory SQLite test helper for isolated unit/integration tests
+- Default Uncategorized category seeded on Hono server startup
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Project scaffolding and configuration** - `67ff860` (feat)
+2. **Task 2: Database schema, shared schemas, seed, and test infrastructure** - `7412ef1` (feat)
+
+## Files Created/Modified
+
+- `vite.config.ts` - Vite config with TanStack Router plugin, React, Tailwind, and API proxy
+- `drizzle.config.ts` - Drizzle Kit config for SQLite schema management
+- `tsconfig.json` - TypeScript config with path aliases and DOM types
+- `package.json` - All dependencies and dev scripts
+- `index.html` - Vite SPA entry point
+- `biome.json` - Biome linter/formatter config
+- `.gitignore` - Updated with GearBox-specific ignores
+- `src/db/schema.ts` - Drizzle table definitions for items, categories, settings
+- `src/db/index.ts` - Database connection singleton with WAL mode and foreign keys
+- `src/db/seed.ts` - Seeds default Uncategorized category
+- `src/shared/schemas.ts` - Zod validation schemas for items and categories
+- `src/shared/types.ts` - TypeScript types inferred from Zod and Drizzle
+- `src/server/index.ts` - Hono server with health check, static serving, seed on startup
+- `src/client/main.tsx` - React 19 entry with TanStack Router and Query providers
+- `src/client/routes/__root.tsx` - Root layout with Outlet and Tailwind import
+- `src/client/routes/index.tsx` - Default route with placeholder text
+- `src/client/app.css` - Tailwind v4 CSS import
+- `tests/helpers/db.ts` - In-memory SQLite test helper with schema and seed
+
+## Decisions Made
+
+- Added `routesDirectory` and `generatedRouteTree` config to TanStack Router Vite plugin since routes live in `src/client/routes` instead of the default `src/routes`
+- Installed `better-sqlite3` as a dev dependency because drizzle-kit CLI cannot use Bun's built-in `bun:sqlite` driver
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 3 - Blocking] TanStack Router plugin could not find routes directory**
+- **Found during:** Task 1 (build verification)
+- **Issue:** TanStack Router defaults to `src/routes` but project uses `src/client/routes`
+- **Fix:** Added `routesDirectory: "./src/client/routes"` and `generatedRouteTree: "./src/client/routeTree.gen.ts"` to plugin config
+- **Files modified:** vite.config.ts
+- **Verification:** `bun run build` succeeds
+- **Committed in:** 67ff860 (Task 1 commit)
+
+**2. [Rule 3 - Blocking] drizzle-kit push requires better-sqlite3**
+- **Found during:** Task 2 (schema push)
+- **Issue:** drizzle-kit cannot use bun:sqlite, requires either better-sqlite3 or @libsql/client
+- **Fix:** Installed better-sqlite3 and @types/better-sqlite3 as dev dependencies
+- **Files modified:** package.json, bun.lock
+- **Verification:** `bunx drizzle-kit push --force` succeeds
+- **Committed in:** 7412ef1 (Task 2 commit)
+
+---
+
+**Total deviations:** 2 auto-fixed (2 blocking)
+**Impact on plan:** Both fixes necessary for build and schema tooling. No scope creep.
+
+## Issues Encountered
+
+None beyond the auto-fixed blocking issues documented above.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+- All infrastructure ready for Plan 01-02 (Backend API: item CRUD, category CRUD, totals, image upload)
+- Database schema in place with tables and foreign keys
+- Shared schemas ready for Hono route validation
+- Test helper ready for service and integration tests

+    Write tests FIRST using createTestDb() from tests/helpers/db.ts. Each test gets a fresh in-memory DB.
+
+    Then implement services:
+
+    1. `src/server/services/item.service.ts`:
+       - Functions accept a db instance parameter (for testability) with default to the production db
+       - getAllItems(): SELECT items JOIN categories, returns items with category name and emoji
+       - getItemById(id): SELECT single item or null
+       - createItem(data: CreateItem): INSERT, return with id and timestamps
+       - updateItem(id, data): UPDATE with updatedAt = new Date(), return updated item
+       - deleteItem(id): SELECT item first (for image filename), DELETE, return the deleted item data
+
+    2. `src/server/services/category.service.ts`:
+       - getAllCategories(): SELECT all, ordered by name
+       - createCategory(data: CreateCategory): INSERT, return with id
+       - updateCategory(id, data): UPDATE name and/or emoji
+       - deleteCategory(id): Guard against deleting id=1. UPDATE all items with this categoryId to categoryId=1, then DELETE the category. Use a transaction.
+
+    3. Totals functions (can live in item.service.ts or a separate totals module):
+       - getCategoryTotals(): Per RESEARCH.md Pattern 4 exactly. SELECT with SUM and COUNT, GROUP BY categoryId, JOIN categories.
+       - getGlobalTotals(): SELECT SUM(weightGrams), SUM(priceCents), COUNT(*) from items.

+# Phase 1 Plan 02: Backend API Summary
+
+**Item/category CRUD with Zod-validated Hono routes, computed totals via SQL aggregates, image upload, and 30 passing tests via TDD**
+
+## Performance
+
+- **Duration:** 3 min
+- **Started:** 2026-03-14T21:37:37Z
+- **Completed:** 2026-03-14T21:40:54Z
+- **Tasks:** 2
+- **Files modified:** 13
+
+## Accomplishments
+
+- Complete item CRUD service layer with category join queries
+- Category CRUD with Uncategorized reassignment on delete (transaction-safe)
+- Per-category and global weight/cost/count totals via SQL SUM/COUNT aggregates
+- Hono API routes with Zod request validation for all endpoints
+- Image upload endpoint with file type and size validation
+- 30 tests passing (20 unit + 10 integration) built via TDD
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Service layer with tests (RED)** - `f906779` (test)
+2. **Task 1: Service layer implementation (GREEN)** - `22757a8` (feat)
+3. **Task 2: API routes, image upload, integration tests** - `029adf4` (feat)
+
+## Files Created/Modified
+
+- `src/server/services/item.service.ts` - Item CRUD business logic with category join
+- `src/server/services/category.service.ts` - Category CRUD with reassignment on delete
+- `src/server/services/totals.service.ts` - Per-category and global totals aggregation
+- `src/server/routes/items.ts` - Hono routes for /api/items with Zod validation
+- `src/server/routes/categories.ts` - Hono routes for /api/categories with delete protection
+- `src/server/routes/totals.ts` - Hono route for /api/totals
+- `src/server/routes/images.ts` - Image upload with type/size validation
+- `src/server/index.ts` - Registered all API routes
+- `tests/services/item.service.test.ts` - 7 unit tests for item CRUD
+- `tests/services/category.service.test.ts` - 7 unit tests for category CRUD
+- `tests/services/totals.test.ts` - 4 unit tests for totals aggregation
+- `tests/routes/items.test.ts` - 6 integration tests for item API
+- `tests/routes/categories.test.ts` - 4 integration tests for category API
+
+## Decisions Made
+
+- Service functions accept `db` as first parameter with production default for dependency injection and testability
+- Routes use Hono context variables (`c.get("db")`) for DB injection, enabling integration tests with in-memory SQLite without mocking
+- Totals computed via SQL aggregates on every read per RESEARCH.md recommendation (never cached)
+- `updateItemSchema.omit({ id: true })` used for PUT routes since id comes from URL params
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+- All backend API endpoints ready for frontend consumption (Plan 01-03)
+- Service layer provides clean interface for TanStack Query hooks
+- Test infrastructure supports both unit and integration testing patterns
+
+## Self-Check: PASSED

+<objective>
+Build the complete frontend collection UI: card grid layout grouped by category, slide-out panel for add/edit with all item fields, category picker combobox, confirmation dialog for delete, image upload, and sticky totals bar.
+
+Purpose: This is the primary user-facing feature of Phase 1 -- the gear collection view where users catalog, organize, and browse their gear.
+Output: A fully functional collection page with CRUD operations, category management, and computed totals.

+  <action>
+    1. Create `src/client/lib/api.ts`: A thin fetch wrapper that throws on non-ok responses with error message from response body. Functions: apiGet(url), apiPost(url, body), apiPut(url, body), apiDelete(url), apiUpload(url, file) for multipart form data.
+
+    2. Create `src/client/lib/formatters.ts`: formatWeight(grams) returns "123g" or "--" if null. formatPrice(cents) returns "$12.34" or "--" if null. These are display-only, no unit conversion in v1.
+
+    3. Create `src/client/hooks/useItems.ts` per RESEARCH.md TanStack Query Hook example: useItems() query, useCreateItem() mutation (invalidates items+totals), useUpdateItem() mutation (invalidates items+totals), useDeleteItem() mutation (invalidates items+totals). All mutations invalidate both "items" and "totals" query keys.
+
+    4. Create `src/client/hooks/useCategories.ts`: useCategories() query, useCreateCategory() mutation (invalidates categories), useUpdateCategory() mutation (invalidates categories), useDeleteCategory() mutation (invalidates categories+items+totals since items may be reassigned).
+
+    5. Create `src/client/hooks/useTotals.ts`: useTotals() query returning { categories: CategoryTotals[], global: GlobalTotals }.
+
+    6. Create `src/client/stores/uiStore.ts` per RESEARCH.md Pattern 3: Zustand store with panelMode, editingItemId, openAddPanel, openEditPanel, closePanel. Also add confirmDeleteItemId: number | null with openConfirmDelete(id) and closeConfirmDelete().
+
+    7. Create `src/client/components/TotalsBar.tsx`: Sticky bar at top of page (position: sticky, top: 0, z-10). Shows total item count, total weight (formatted), total cost (formatted). Uses useTotals() hook. Clean minimal style per user decision: white background, subtle bottom border, light text.
+
+    8. Create `src/client/components/CategoryHeader.tsx`: Receives category name, emoji, weight subtotal, cost subtotal, item count. Displays: emoji + name prominently, then subtotals in lighter text. Include edit (rename/emoji) and delete buttons that appear on hover. Delete triggers confirmation. Per user decision: empty categories are NOT shown (filtering happens in parent).
+
+    9. Create `src/client/components/ItemCard.tsx`: Card displaying item name (prominent), image (if imageFilename exists, use /uploads/{filename} as src with object-fit cover), and tag-style chips for weight, price, and category. Per user decisions: clean, minimal, light and airy aesthetic with white backgrounds and whitespace. Clicking the card calls openEditPanel(item.id).
+
+    10. Create `src/client/components/ConfirmDialog.tsx`: Modal dialog with "Are you sure you want to delete {itemName}?" message, Cancel and Delete buttons. Delete button is red/destructive. Uses confirmDeleteItemId from uiStore. Calls useDeleteItem mutation on confirm, then closes.
+
+    11. Create `src/client/components/ImageUpload.tsx`: File input that accepts image/jpeg, image/png, image/webp. On file select, uploads via POST /api/images, returns filename to parent via onChange callback. Shows preview of selected/existing image. Max 5MB validation client-side before upload.

+  <action>
+    1. Create `src/client/components/CategoryPicker.tsx`: Combobox component per user decision. Type to search existing categories, select from filtered dropdown, or create new inline. Uses useCategories() for the list and useCreateCategory() to create new. Props: value (categoryId), onChange(categoryId). Implementation: text input with dropdown list filtered by input text. If no match and input non-empty, show "Create [input]" option. On selecting create, call mutation, wait for result, then call onChange with new category id. Proper ARIA attributes: role combobox, listbox, option. Keyboard navigation: arrow keys to navigate, Enter to select, Escape to close.
+
+    2. Create `src/client/components/SlideOutPanel.tsx`: Container component that slides in from the right side of the screen. Per user decisions: collection remains visible behind (use fixed positioning with right: 0, width ~400px on desktop, full width on mobile). Tailwind transition-transform + translate-x for animation. Props: isOpen, onClose, title (string). Renders children inside. Backdrop overlay (semi-transparent) that closes panel on click. Close button (X) in header.
+
+    3. Create `src/client/components/ItemForm.tsx`: Form rendered inside SlideOutPanel. Props: mode ("add" | "edit"), itemId? (for edit mode). When edit mode: fetch item by id (useItems data or separate query), pre-fill all fields. Fields: name (text, required), weight in grams (number input, labeled "Weight (g)"), price in dollars (number input that converts to/from cents for display -- show $, store cents), category (CategoryPicker component), notes (textarea), product link (url input), image (ImageUpload component). On submit: call useCreateItem or useUpdateItem depending on mode, close panel on success. Validation: use Zod createItemSchema for client-side validation, show inline error messages. Per Claude's discretion: all fields visible in a single scrollable form (not tabbed/grouped).
+
+    4. Update `src/client/routes/__root.tsx`: Import and render TotalsBar at top. Render Outlet below. Render SlideOutPanel (controlled by uiStore panelMode). When panelMode is "add", render ItemForm with mode="add" inside panel. When "edit", render ItemForm with mode="edit" and itemId from uiStore. Render ConfirmDialog. Add a floating "+" button (fixed, bottom-right) to trigger openAddPanel().
+
+    5. Update `src/client/routes/index.tsx` as the collection page: Use useItems() to get all items. Use useTotals() to get category totals (for subtotals in headers). Group items by categoryId. For each category that has items (skip empty per user decision): render CategoryHeader with subtotals, then render a responsive card grid of ItemCards (CSS grid: 1 col mobile, 2 col md, 3 col lg). If no items exist at all, show an empty state message encouraging the user to add their first item. Per user decision: card grid layout grouped by category headers.

+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None.

+None - no external service configuration required.
+
+## Next Phase Readiness
+
+- Complete collection UI ready for end-to-end testing with backend

+  <action>
+    1. Create `src/server/routes/settings.ts`:
+       - GET /api/settings/:key returns { key, value } or 404
+       - PUT /api/settings/:key with body { value } upserts the setting (INSERT OR REPLACE into settings table)
+       - Export as settingsRoutes
+
+    2. Update `src/server/index.ts`: Register app.route("/api/settings", settingsRoutes).
+
+    3. Create `src/client/hooks/useSettings.ts`:
+       - useSetting(key): TanStack Query hook that fetches GET /api/settings/{key}, returns value or null if 404
+       - useUpdateSetting(): mutation that PUTs /api/settings/{key} with { value }, invalidates ["settings", key]
+       - Specifically export useOnboardingComplete() that wraps useSetting("onboardingComplete") for convenience
+
+    4. Create `src/client/components/OnboardingWizard.tsx`: Per user decision, a step-by-step modal overlay (not full-page takeover). 3 steps:
+       - Step 1: Welcome screen. "Welcome to GearBox!" with brief description. "Let's set up your first category." Next button.
+       - Step 2: Create first category. Show a mini form with category name input and emoji picker (simple: text input for emoji, user pastes/types emoji). Use useCreateCategory mutation. On success, advance to step 3.
+       - Step 3: Add first item. Show a simplified item form (just name, weight, price, and the just-created category pre-selected). Use useCreateItem mutation. On success, show "You're all set!" and a Done button.
+       - On Done: call useUpdateSetting to set "onboardingComplete" to "true". Close wizard.
+       - Modal styling: centered overlay with backdrop blur, white card, clean typography, step indicator (1/3, 2/3, 3/3).
+       - Allow skipping the wizard entirely with a "Skip" link that still sets onboardingComplete.
+
+    5. Update `src/client/routes/__root.tsx`: On app load, check useOnboardingComplete(). If value is not "true" (null or missing), render OnboardingWizard as an overlay on top of everything. If "true", render normally. Show a loading state while the setting is being fetched (don't flash the wizard).
+
+    6. Per RESEARCH.md Pitfall 3: onboarding state is persisted in SQLite settings table, NOT just Zustand. Zustand is only for transient UI state (panel, dialog). The settings table is the source of truth for whether onboarding is complete.

+
+    ONBOARDING:
+    4. Verify onboarding wizard appears as a modal overlay
+    5. Step through: create a category (e.g. "Shelter" with tent emoji), add an item (e.g. "Tent, 1200g, $350")
+    6. Complete wizard, verify it closes and collection view shows
+
+    COLLECTION VIEW:
+    7. Verify the item appears in a card with name, weight chip, price chip

+    ADD/EDIT:
+    10. Click the "+" button, verify slide-out panel opens from right
+    11. Add another item in a new category, verify both categories appear with correct subtotals
+    12. Click an existing card, verify panel opens with pre-filled data for editing
+    13. Edit the weight, save, verify totals update
+
+    CATEGORY MANAGEMENT:

+# Phase 1: Foundation and Collection - Context
+
+**Gathered:** 2026-03-14
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+Project scaffolding (Bun + Hono + React + Vite + SQLite via Drizzle), database schema for items and categories, and complete gear collection CRUD with category management and aggregate totals. No threads, no setups, no dashboard — those are later phases.
+
+</domain>
+
+<decisions>
+## Implementation Decisions
+
+### Collection Layout
+- Card grid layout, grouped by category headers
+- Each card shows: item name (prominent), then tag-style chips for weight, price, and category
+- Item image displayed on the card for visual identification
+- Items grouped under category headers with per-category weight/cost subtotals
+- Global sticky totals bar at the top showing total items, weight, and cost
+- Empty categories are hidden from the collection view (not shown)
+
+### Item Editing Flow
+- Slide-out panel from the right side for both adding and editing items
+- Same panel component for add (empty) and edit (pre-filled)
+- Collection remains visible behind the panel for context
+- Confirmation dialog before deleting items ("Are you sure?")
+
+### Category Management
+- Single-level categories only (no subcategories)
+- Searchable category picker in the item form — type to find existing or create new
+- Categories editable from the collection overview (rename, delete, change icon)
+- Each category gets an emoji/icon for visual distinction
+- Deleting a category moves its items to "Uncategorized" default category
+
+### First-Run Experience
+- Step-by-step onboarding wizard for first-time users
+- Guides through: create first category, add first item
+- After onboarding, normal collection view takes over
+
+### Claude's Discretion
+- Form layout for item add/edit panel (all fields visible vs grouped sections)
+- Loading states and skeleton design
+- Exact spacing, typography, and Tailwind styling choices
+- Error state handling and validation feedback
+- Weight unit storage (grams internally, display in user's preferred unit can be deferred to v2)
+
+</decisions>
+
+<specifics>
+## Specific Ideas
+
+- Cards should feel clean and minimal — "light and airy" aesthetic with white/light backgrounds, lots of whitespace
+- Item info displayed as tag-style chips (not labels with values) — compact, scannable
+- Category picker should work like a combobox: type to search, select existing, or create new inline
+- Photos on cards are important for visual identification even in v1
+
+</specifics>
+
+<code_context>
+## Existing Code Insights
+
+### Reusable Assets
+- None — greenfield project, no existing code
+
+### Established Patterns
+- None yet — Phase 1 establishes all patterns
+
+### Integration Points
+- Bun runtime with bun:sqlite for database
+- Hono for API server
+- React 19 + Vite 8 for frontend
+- Drizzle ORM for type-safe database access
+- Tailwind v4 for styling
+- TanStack Router for client-side routing
+
+</code_context>
+
+<deferred>
+## Deferred Ideas
+
+- Subcategories (e.g. "Bags" → "Handlebar Bag") — revisit if single-level feels limiting
+- Photos are noted as important for cards; image upload implementation is technically in scope (COLL-01 mentions item details) but full photo management is v2

+# Phase 1: Foundation and Collection - Research
+
+**Researched:** 2026-03-14
+**Domain:** Full-stack web app scaffolding, SQLite CRUD, React SPA with collection management
+**Confidence:** HIGH
+
+## Summary
+
+Phase 1 is a greenfield build establishing the entire project stack: Bun runtime with Hono API server, React 19 SPA via Vite with TanStack Router, Drizzle ORM over bun:sqlite, and Tailwind v4 styling. The phase delivers complete gear collection CRUD (items and categories) with aggregate weight/cost totals, a slide-out panel for add/edit, a card grid grouped by category, and a first-run onboarding wizard.
+
+The critical architectural decision is using **Vite as the frontend dev server** (required by TanStack Router's file-based routing plugin) with **Hono on Bun as the backend**, connected via Vite's dev proxy. This is NOT Bun's native fullstack HTML entrypoint pattern -- TanStack Router requires the Vite plugin, which means Vite owns the frontend build pipeline. In production, Hono serves the Vite-built static assets alongside API routes from a single Bun process.
+
+A key blocker from STATE.md has been resolved: `@hono/zod-validator` now supports Zod 4 (merged May 2025, PR #1173). The project can use Zod 4.x without pinning to 3.x.
+
+**Primary recommendation:** Scaffold with Vite + TanStack Router for frontend, Hono + Drizzle on Bun for backend, with categories as a first-class table (not just a text field on items) to support emoji icons, rename, and delete-with-reassignment.
+
+<user_constraints>

+
+## Phase Requirements
+
+| ID | Description | Research Support |
+|----|-------------|-----------------|

+| COLL-02 | User can edit and delete gear items | Hono PUT/DELETE endpoints, same slide-out panel pre-filled for edit, confirmation dialog for delete, image cleanup on item delete |
+| COLL-03 | User can organize items into user-defined categories | Separate categories table with emoji field, combobox category picker, category CRUD endpoints, "Uncategorized" default category, reassignment on category delete |
+| COLL-04 | User can see automatic weight and cost totals by category and overall | SQL SUM aggregates via Drizzle, computed on read (never cached), sticky totals bar component, per-category subtotals in group headers |
+
+</phase_requirements>
+
+## Standard Stack
+
+### Core
+| Library | Version | Purpose | Why Standard |
+|---------|---------|---------|--------------|
+| Bun | 1.3.x | Runtime, package manager | Built-in SQLite, native TS, fast installs |
+| React | 19.2.x | UI framework | Locked in CONTEXT.md |
+| Vite | 8.x | Frontend dev server + production builds | Required by TanStack Router plugin for file-based routing |
+| Hono | 4.12.x | Backend API framework | Web Standards, first-class Bun support, tiny footprint |
+| Drizzle ORM | 0.45.x | Database ORM + migrations | Type-safe SQL, native bun:sqlite driver, built-in migration tooling |
+| Tailwind CSS | 4.2.x | Styling | CSS-native config, auto content detection, microsecond incremental builds |
+| TanStack Router | 1.x | Client-side routing | Type-safe routing with file-based route generation via Vite plugin |
+| TanStack Query | 5.x | Server state management | Handles fetching, caching, cache invalidation on mutations |
+| Zustand | 5.x | Client state management | UI state: panel open/close, active filters, onboarding step |
+| Zod | 4.x | Schema validation | Shared between client forms and Hono API validation. Zod 4 confirmed compatible with @hono/zod-validator (PR #1173, May 2025) |
+| TypeScript | 5.x | Type safety | Bun transpiles natively, required by Drizzle and TanStack Router |
+
+### Supporting
+| Library | Version | Purpose | When to Use |
+|---------|---------|---------|-------------|
+| @tanstack/router-plugin | latest | Vite plugin for file-based routing | Required in vite.config.ts, must be listed BEFORE @vitejs/plugin-react |
+| @hono/zod-validator | 0.7.6+ | Request validation middleware | Validate API request bodies/params using Zod schemas |
+| drizzle-kit | latest | DB migrations CLI | `bunx drizzle-kit generate` and `bunx drizzle-kit push` for schema changes |
+| clsx | 2.x | Conditional class names | Building components with variant styles |
+| @vitejs/plugin-react | latest (Vite 8 compatible) | React HMR/JSX | Required in vite.config.ts for Fast Refresh |
+| @tailwindcss/vite | latest | Tailwind Vite plugin | Required in vite.config.ts for Tailwind v4 |
+| @biomejs/biome | latest | Linter + formatter | Single tool replacing ESLint + Prettier |
+
+### Alternatives Considered
+| Instead of | Could Use | Tradeoff |
+|------------|-----------|----------|
+| Vite + Hono | Bun fullstack (HTML entrypoints) | Bun fullstack is simpler but incompatible with TanStack Router file-based routing which requires the Vite plugin |
+| Zod 4.x | Zod 3.23.x | No need to pin -- @hono/zod-validator supports Zod 4 as of May 2025 |
+| Separate categories table | Category as text field on items | Text field cannot store emoji/icon, cannot rename without updating all items, cannot enforce "Uncategorized" default cleanly |
+
+**Installation:**
+```bash

+
+### Pattern 1: Vite Frontend + Hono Backend (Dev Proxy)
+**What:** Vite runs the frontend dev server with HMR. Hono runs on Bun as the API server on a separate port. Vite's `server.proxy` forwards `/api/*` to Hono. In production, Hono serves Vite's built output as static files.
+**When to use:** When TanStack Router (or any Vite plugin) is required for the frontend.
+**Example:**
+```typescript
+// vite.config.ts
+import { defineConfig } from "vite";
+import react from "@vitejs/plugin-react";
+import tailwindcss from "@tailwindcss/vite";
+import { tanstackRouter } from "@tanstack/router-plugin/vite";
+
+export default defineConfig({
+  plugins: [
+    tanstackRouter({ target: "react", autoCodeSplitting: true }),
+    react(),
+    tailwindcss(),
+  ],
+  server: {
+    proxy: {
+      "/api": "http://localhost:3000",
+      "/uploads": "http://localhost:3000",
+    },
+  },
+  build: {
+    outDir: "dist/client",
+  },
+});
+```
+
+```typescript
+// src/server/index.ts
+import { Hono } from "hono";
+import { serveStatic } from "hono/bun";
+import { itemRoutes } from "./routes/items";
+import { categoryRoutes } from "./routes/categories";
+
+const app = new Hono();
+
+// API routes
+app.route("/api/items", itemRoutes);
+app.route("/api/categories", categoryRoutes);
+
+// Serve uploaded images
+app.use("/uploads/*", serveStatic({ root: "./" }));
+
+// Serve Vite-built SPA in production
+if (process.env.NODE_ENV === "production") {
+  app.use("/*", serveStatic({ root: "./dist/client" }));
+  app.get("*", serveStatic({ path: "./dist/client/index.html" }));
+}
+
+export default { port: 3000, fetch: app.fetch };
+```
+
+### Pattern 2: Categories as a First-Class Table
+**What:** Categories are a separate table with id, name, and emoji fields. Items reference categories via foreign key. An "Uncategorized" category with a known ID (1) is seeded on DB init.
+**When to use:** When categories need independent properties (emoji/icon), rename support, and delete-with-reassignment.
+**Example:**
+```typescript
+// db/schema.ts
+import { sqliteTable, text, integer, real } from "drizzle-orm/sqlite-core";
+
+export const categories = sqliteTable("categories", {
+  id: integer("id").primaryKey({ autoIncrement: true }),
+  name: text("name").notNull().unique(),
+  emoji: text("emoji").notNull().default("📦"),
+  createdAt: integer("created_at", { mode: "timestamp" }).notNull()
+    .$defaultFn(() => new Date()),
+});
+
+export const items = sqliteTable("items", {
+  id: integer("id").primaryKey({ autoIncrement: true }),
+  name: text("name").notNull(),
+  weightGrams: real("weight_grams"),
+  priceCents: integer("price_cents"),
+  categoryId: integer("category_id").notNull().references(() => categories.id),
+  notes: text("notes"),
+  productUrl: text("product_url"),
+  imageFilename: text("image_filename"),
+  createdAt: integer("created_at", { mode: "timestamp" }).notNull()
+    .$defaultFn(() => new Date()),
+  updatedAt: integer("updated_at", { mode: "timestamp" }).notNull()
+    .$defaultFn(() => new Date()),
+});
+```
+
+### Pattern 3: Slide-Out Panel with Shared Component
+**What:** A single `SlideOutPanel` component serves both add and edit flows. When adding, fields are empty. When editing, fields are pre-filled from the existing item. The panel slides in from the right, overlaying (not replacing) the collection view.
+**When to use:** Per CONTEXT.md locked decision.
+**State management:**
+```typescript
+// stores/uiStore.ts
+import { create } from "zustand";
+
+interface UIState {
+  panelMode: "closed" | "add" | "edit";
+  editingItemId: number | null;
+  openAddPanel: () => void;
+  openEditPanel: (itemId: number) => void;
+  closePanel: () => void;
+}
+
+export const useUIStore = create<UIState>((set) => ({
+  panelMode: "closed",
+  editingItemId: null,
+  openAddPanel: () => set({ panelMode: "add", editingItemId: null }),
+  openEditPanel: (itemId) => set({ panelMode: "edit", editingItemId: itemId }),
+  closePanel: () => set({ panelMode: "closed", editingItemId: null }),
+}));
+```
+
+### Pattern 4: Computed Totals (Never Cached)
+**What:** Weight and cost totals are computed on every read via SQL aggregates. Never store totals as columns.
+**Why:** Avoids stale data bugs when items are added, edited, or deleted.
+**Example:**
+```typescript
+// server/services/item.service.ts
+import { db } from "../../db";
+import { items, categories } from "../../db/schema";
+import { eq, sql } from "drizzle-orm";
+
+export function getCategoryTotals() {
+  return db
+    .select({
+      categoryId: items.categoryId,
+      categoryName: categories.name,
+      categoryEmoji: categories.emoji,
+      totalWeight: sql<number>`COALESCE(SUM(${items.weightGrams}), 0)`,
+      totalCost: sql<number>`COALESCE(SUM(${items.priceCents}), 0)`,
+      itemCount: sql<number>`COUNT(*)`,
+    })
+    .from(items)
+    .innerJoin(categories, eq(items.categoryId, categories.id))
+    .groupBy(items.categoryId)
+    .all();
+}
+
+export function getGlobalTotals() {
+  return db
+    .select({
+      totalWeight: sql<number>`COALESCE(SUM(${items.weightGrams}), 0)`,
+      totalCost: sql<number>`COALESCE(SUM(${items.priceCents}), 0)`,
+      itemCount: sql<number>`COUNT(*)`,
+    })
+    .from(items)
+    .get();
+}
+```
+
+### Anti-Patterns to Avoid
+- **Storing money as floats:** Use integer cents (`priceCents`). Format to dollars only in the display layer. `0.1 + 0.2 !== 0.3` in JavaScript.
+- **Category as a text field on items:** Cannot store emoji, cannot rename without updating all items, cannot enforce default category on delete.
+- **Caching totals in the database:** Always compute from source data. SQLite SUM() over hundreds of items is sub-millisecond.
+- **Absolute paths for images:** Store relative paths only (`uploads/{filename}`). Absolute paths break on deployment or directory changes.
+- **Requiring all fields to add an item:** Only require `name`. Weight, price, category, etc. should be optional. Users fill in details over time.
+
+## Don't Hand-Roll
+
+| Problem | Don't Build | Use Instead | Why |
+|---------|-------------|-------------|-----|
+| Database migrations | Custom SQL scripts | Drizzle Kit (`drizzle-kit generate/push`) | Migration ordering, conflict detection, rollback support |
+| Form validation | Manual if/else checks | Zod schemas shared between client and server | Single source of truth, type inference, consistent error messages |
+| API data fetching/caching | useState + useEffect + fetch | TanStack Query hooks | Handles loading/error states, cache invalidation, refetching, deduplication |
+| Combobox/autocomplete | Custom input with dropdown | Headless UI pattern (build from primitives with proper ARIA) or a lightweight combobox library | Keyboard navigation, screen reader support, focus management are deceptively hard |
+| Slide-out panel animation | CSS transitions from scratch | Tailwind `transition-transform` + `translate-x` utilities | Consistent timing, GPU-accelerated, respects prefers-reduced-motion |
+| Image resizing on upload | Custom canvas manipulation | Sharp library or accept-and-store (resize deferred to v2) | Sharp handles EXIF rotation, format conversion, memory management |
+
+**Key insight:** For Phase 1, defer image resizing/thumbnailing. Accept and store the uploaded image as-is. Thumbnail generation can be added in v2 without schema changes (imageFilename stays the same, just generate a thumb variant).
+
+## Common Pitfalls
+
+### Pitfall 1: Bun Fullstack vs Vite Confusion
+**What goes wrong:** Attempting to use Bun's native `Bun.serve()` with HTML entrypoints AND TanStack Router, which requires Vite's build pipeline.
+**Why it happens:** Bun's fullstack dev server is compelling but incompatible with TanStack Router's file-based routing Vite plugin.
+**How to avoid:** Use Vite for frontend (with TanStack Router plugin). Use Hono on Bun for backend. Connect via Vite proxy in dev, static file serving in prod.
+**Warning signs:** Import errors from `@tanstack/router-plugin/vite`, missing route tree generation file.
+
+### Pitfall 2: Category Delete Without Reassignment
+**What goes wrong:** Deleting a category with foreign key constraints either fails (FK violation) or cascades (deletes all items in that category).
+**Why it happens:** Using `ON DELETE CASCADE` or not handling FK constraints at all.
+**How to avoid:** Before deleting a category, reassign all its items to the "Uncategorized" default category (id=1). Then delete. This is a two-step transaction.
+**Warning signs:** FK constraint errors on category delete, or silent item deletion.
+
+### Pitfall 3: Onboarding State Persistence
+**What goes wrong:** User completes onboarding, refreshes the page, and sees the wizard again.
+**Why it happens:** Storing onboarding completion state only in Zustand (memory). State is lost on page refresh.
+**How to avoid:** Store `onboardingComplete` as a flag in SQLite (a simple `settings` table or a dedicated endpoint). Check on app load.
+**Warning signs:** Onboarding wizard appears on every fresh page load.
+
+### Pitfall 4: Image Upload Without Cleanup
+**What goes wrong:** Deleting an item leaves its image file on disk. Over time, orphaned images accumulate.
+**Why it happens:** DELETE endpoint removes the DB record but forgets to unlink the file.
+**How to avoid:** In the item delete service, check `imageFilename`, unlink the file from `uploads/` before or after DB delete. Wrap in try/catch -- file missing is not an error worth failing the delete over.
+**Warning signs:** `uploads/` directory grows larger than expected, files with no matching item records.
+
+### Pitfall 5: TanStack Router Plugin Order in Vite Config
+**What goes wrong:** File-based routes are not generated, `routeTree.gen.ts` is missing or stale.
+**Why it happens:** TanStack Router plugin must be listed BEFORE `@vitejs/plugin-react` in the Vite plugins array.
+**How to avoid:** Always order: `tanstackRouter()`, then `react()`, then `tailwindcss()`.
+**Warning signs:** Missing `routeTree.gen.ts`, type errors on route imports.
+
+### Pitfall 6: Forgetting PRAGMA foreign_keys = ON
+**What goes wrong:** Foreign key constraints between items and categories are silently ignored. Items can reference non-existent categories.
+**Why it happens:** SQLite has foreign key support but it is OFF by default. Must be enabled per connection.
+**How to avoid:** Run `PRAGMA foreign_keys = ON` immediately after opening the database connection, before any queries.
+**Warning signs:** Items with categoryId pointing to deleted categories, no errors on invalid inserts.
+
+## Code Examples
+
+### Database Connection Singleton
+```typescript
+// src/db/index.ts
+import { Database } from "bun:sqlite";
+import { drizzle } from "drizzle-orm/bun-sqlite";
+import * as schema from "./schema";
+
+const sqlite = new Database("gearbox.db");
+sqlite.run("PRAGMA journal_mode = WAL");
+sqlite.run("PRAGMA foreign_keys = ON");
+
+export const db = drizzle(sqlite, { schema });
+```
+
+### Drizzle Config
+```typescript
+// drizzle.config.ts
+import { defineConfig } from "drizzle-kit";
+
+export default defineConfig({
+  out: "./drizzle",
+  schema: "./src/db/schema.ts",
+  dialect: "sqlite",
+  dbCredentials: {
+    url: "gearbox.db",
+  },
+});
+```
+
+### Shared Zod Schemas
+```typescript
+// src/shared/schemas.ts
+import { z } from "zod";
+
+export const createItemSchema = z.object({
+  name: z.string().min(1, "Name is required"),
+  weightGrams: z.number().nonnegative().optional(),
+  priceCents: z.number().int().nonnegative().optional(),
+  categoryId: z.number().int().positive(),
+  notes: z.string().optional(),
+  productUrl: z.string().url().optional().or(z.literal("")),
+});
+
+export const updateItemSchema = createItemSchema.partial().extend({
+  id: z.number().int().positive(),
+});
+
+export const createCategorySchema = z.object({
+  name: z.string().min(1, "Category name is required"),
+  emoji: z.string().min(1).max(4).default("📦"),
+});
+
+export const updateCategorySchema = z.object({
+  id: z.number().int().positive(),
+  name: z.string().min(1).optional(),
+  emoji: z.string().min(1).max(4).optional(),
+});
+
+export type CreateItem = z.infer<typeof createItemSchema>;
+export type UpdateItem = z.infer<typeof updateItemSchema>;
+export type CreateCategory = z.infer<typeof createCategorySchema>;
+```
+
+### Hono Item Routes with Zod Validation
+```typescript
+// src/server/routes/items.ts
+import { Hono } from "hono";
+import { zValidator } from "@hono/zod-validator";
+import { createItemSchema, updateItemSchema } from "../../shared/schemas";
+import { db } from "../../db";
+import { items } from "../../db/schema";
+import { eq } from "drizzle-orm";
+
+const app = new Hono();
+
+app.get("/", async (c) => {
+  const allItems = db.select().from(items).all();
+  return c.json(allItems);
+});
+
+app.post("/", zValidator("json", createItemSchema), async (c) => {
+  const data = c.req.valid("json");
+  const result = db.insert(items).values(data).returning().get();
+  return c.json(result, 201);
+});
+
+app.put("/:id", zValidator("json", updateItemSchema), async (c) => {
+  const id = Number(c.req.param("id"));
+  const data = c.req.valid("json");
+  const result = db.update(items).set({ ...data, updatedAt: new Date() })
+    .where(eq(items.id, id)).returning().get();
+  if (!result) return c.json({ error: "Item not found" }, 404);
+  return c.json(result);
+});
+
+app.delete("/:id", async (c) => {
+  const id = Number(c.req.param("id"));
+  // Clean up image file if exists
+  const item = db.select().from(items).where(eq(items.id, id)).get();
+  if (!item) return c.json({ error: "Item not found" }, 404);
+  if (item.imageFilename) {
+    try { await Bun.file(`uploads/${item.imageFilename}`).exists() &&
+      await Bun.$`rm uploads/${item.imageFilename}`; } catch {}
+  }
+  db.delete(items).where(eq(items.id, id)).run();
+  return c.json({ success: true });
+});
+
+export { app as itemRoutes };
+```
+
+### TanStack Query Hook for Items
+```typescript
+// src/client/hooks/useItems.ts
+import { useQuery, useMutation, useQueryClient } from "@tanstack/react-query";
+import type { CreateItem, UpdateItem } from "../../shared/schemas";
+
+const API = "/api/items";
+
+export function useItems() {
+  return useQuery({
+    queryKey: ["items"],
+    queryFn: async () => {
+      const res = await fetch(API);
+      if (!res.ok) throw new Error("Failed to fetch items");
+      return res.json();
+    },
+  });
+}
+
+export function useCreateItem() {
+  const queryClient = useQueryClient();
+  return useMutation({
+    mutationFn: async (data: CreateItem) => {
+      const res = await fetch(API, {
+        method: "POST",
+        headers: { "Content-Type": "application/json" },
+        body: JSON.stringify(data),
+      });
+      if (!res.ok) throw new Error("Failed to create item");
+      return res.json();
+    },
+    onSuccess: () => {
+      queryClient.invalidateQueries({ queryKey: ["items"] });
+      queryClient.invalidateQueries({ queryKey: ["totals"] });
+    },
+  });
+}
+```
+
+### Seed Default Category
+```typescript
+// src/db/seed.ts
+import { db } from "./index";
+import { categories } from "./schema";
+
+export function seedDefaults() {
+  const existing = db.select().from(categories).all();
+  if (existing.length === 0) {
+    db.insert(categories).values({
+      name: "Uncategorized",
+      emoji: "📦",
+    }).run();
+  }
+}
+```
+
+## State of the Art
+
+| Old Approach | Current Approach | When Changed | Impact |
+|--------------|------------------|--------------|--------|
+| Zod 3.x + @hono/zod-validator | Zod 4.x fully supported | May 2025 (PR #1173) | No need to pin Zod 3.x. Resolves STATE.md blocker. |
+| Tailwind config via JS | Tailwind v4 CSS-native config | Jan 2025 | No tailwind.config.js file. Theme defined in CSS via @theme directive. |
+| Vite 7 (esbuild/Rollup) | Vite 8 (Rolldown-based) | 2025 | 5-30x faster builds. Same config API. |
+| React Router v6/v7 | TanStack Router v1 | 2024 | Type-safe params, file-based routes, better SPA experience |
+| bun:sqlite manual SQL | Drizzle ORM 0.45.x | Ongoing | Type-safe queries, migration tooling, schema-as-code |
+
+**Deprecated/outdated:**
+- `tailwind.config.js`: Use CSS `@theme` directive in Tailwind v4
+- `better-sqlite3`: Use `bun:sqlite` (built-in, 3-6x faster)
+- Vite `server.proxy` syntax: Verify correct format for Vite 8 (string shorthand still works)
+
+## Open Questions
+
+1. **Image upload size limit and accepted formats**
+   - What we know: CONTEXT.md says photos on cards are important for visual identification
+   - What's unclear: Maximum file size, accepted formats (jpg/png/webp), whether to resize on upload or defer to v2
+   - Recommendation: Accept jpg/png/webp up to 5MB. Store as-is in `uploads/`. Defer resizing/thumbnailing to v2. Use `object-fit: cover` in CSS for consistent card display.
+
+2. **Onboarding wizard scope**
+   - What we know: Step-by-step guide through "create first category, add first item"
+   - What's unclear: Exact number of steps, whether it is a modal overlay or a full-page takeover
+   - Recommendation: 2-3 step modal overlay. Step 1: Welcome + create first category (with emoji picker). Step 2: Add first item to that category. Step 3: Done, show collection. Store completion flag in a `settings` table.
+
+3. **Weight input UX**
+   - What we know: Store grams internally. Display unit deferred to v2.
+   - What's unclear: Should the input field accept grams only, or allow free-text with unit suffix?
+   - Recommendation: For v1, use a numeric input labeled "Weight (g)". Clean and simple. V2 adds unit selector.

+
+## Requirements Coverage
+
+| Requirement | Description | Plans | Status | Evidence |
+|-------------|-------------|-------|--------|----------|
+| COLL-01 | User can add gear items with name, weight, price, category, notes, and product link | 01-01, 01-02, 01-03, 01-04 | SATISFIED | createItemSchema validates all fields; POST /api/items creates; ItemForm renders all fields wired to useCreateItem |
+| COLL-02 | User can edit and delete gear items | 01-02, 01-03, 01-04 | SATISFIED | PUT /api/items/:id updates; DELETE cleans up image; ItemForm edit mode pre-fills; ConfirmDialog handles delete |
+| COLL-03 | User can organize items into user-defined categories | 01-01, 01-02, 01-03, 01-04 | SATISFIED | categories table with FK; category CRUD API with reassignment on delete; CategoryPicker with inline create; CategoryHeader with rename/delete |
+| COLL-04 | User can see automatic weight and cost totals by category and overall | 01-02, 01-03, 01-04 | SATISFIED | getCategoryTotals/getGlobalTotals via SQL SUM/COUNT; GET /api/totals; TotalsBar and CategoryHeader display values |
+
+All 4 requirements are satisfied at the data and API layer. COLL-01 has a partial degradation (image upload fails due to field name mismatch) but the core add-item functionality works.
+
+---
+
+## Anti-Patterns Found
+
+| File | Line | Pattern | Severity | Impact |
+|------|------|---------|----------|--------|
+| src/client/lib/api.ts | 55 | `formData.append("file", file)` — wrong field name | Blocker | Image upload always returns 400; upload feature is non-functional |
+| src/server/services/category.service.ts | 67-73 | Comment says "Use a transaction" but no transaction wrapper used | Warning | Two-statement delete without atomicity; edge-case data integrity risk if server crashes mid-delete |
+
+---
+
+## Human Verification Required
+
+### 1. End-to-End Collection Experience
+
+**Test:** Delete gearbox.db, start both servers (bun run dev:server, bun run dev:client), visit http://localhost:5173
+**Expected:** Onboarding wizard appears as modal overlay; step through category creation and item creation; wizard closes and collection view shows the added item as a card under the correct category; sticky totals bar reflects the item count, weight, and cost; clicking the card opens the slide-out panel pre-filled; edits save and totals update; deleting an item shows the confirm dialog and removes the card; data persists on page refresh (wizard does not reappear)
+**Why human:** Visual rendering, animation transitions, and real-time reactivity require a browser
+
+### 2. Image Upload After Field Name Fix
+
+**Test:** After fixing the field name mismatch, edit an item and upload an image
+**Expected:** File picker opens, image uploads successfully, thumbnail preview appears in ImageUpload component, item card displays the image with object-cover aspect-[4/3] layout
+**Why human:** File picker interaction and visual image display require browser
+
+### 3. Category Delete Atomicity
+
+**Test:** Delete a category that has items; verify items appear under Uncategorized
+**Expected:** Items immediately move to Uncategorized; no orphaned items with invalid categoryId
+**Why human:** The service lacks a true transaction wrapper (despite the comment); normal operation works but crash-recovery scenario requires manual inspection or a stress test
+
+---
+
+## Gaps Summary
+
+One bug blocks the image upload feature. The client-side `apiUpload` function in `src/client/lib/api.ts` appends the file under the FormData field name `"file"` (line 55), but the server route in `src/server/routes/images.ts` reads `body["image"]` (line 13). This mismatch means every image upload request returns HTTP 400 with "No image file provided". The fix is a one-line change to either file. All other 15 must-haves are fully verified: infrastructure builds and tests pass (30/30), all CRUD API endpoints work with correct validation, the frontend collection UI is substantively implemented and wired to the API, the onboarding wizard persists state correctly to SQLite, and all four COLL requirements are satisfied at the functional level.
+
+A secondary warning: the category delete service claims to use a transaction (comment on line 67) but executes two separate statements. This is not a goal-blocking issue but represents a reliability gap that should be noted for hardening.

+<objective>
+Build the complete backend API for planning threads: database schema, shared validation schemas, service layer with thread resolution transaction, and Hono API routes. All via TDD.
+
+Purpose: Establish the data model and API that the frontend (Plan 02) will consume. Thread resolution -- the atomic operation that creates a collection item from a candidate and archives the thread -- is the core business logic of this phase.
+
+Output: Working API endpoints for thread CRUD, candidate CRUD, and thread resolution, with comprehensive tests.

+  <action>
+    **RED phase first:**
+
+    1. Add `threads` and `threadCandidates` tables to `src/db/schema.ts` following the existing pattern. Schema per RESEARCH.md Pattern 1: threads has id, name, status (default "active"), resolvedCandidateId, createdAt, updatedAt. threadCandidates has id, threadId (FK to threads with cascade delete), and the same fields as items (name, weightGrams, priceCents, categoryId FK to categories, notes, productUrl, imageFilename, createdAt, updatedAt).
+
+    2. Add Zod schemas to `src/shared/schemas.ts`: createThreadSchema (name required), updateThreadSchema (name optional), createCandidateSchema (same shape as createItemSchema), updateCandidateSchema (partial of create), resolveThreadSchema (candidateId required).
+
+    3. Add types to `src/shared/types.ts`: Thread (inferred from Drizzle threads table), ThreadCandidate (inferred from Drizzle threadCandidates table), CreateThread, UpdateThread, CreateCandidate, UpdateCandidate, ResolveThread (from Zod schemas).
+
+    4. Update `tests/helpers/db.ts`: Add CREATE TABLE statements for `threads` and `thread_candidates` matching the Drizzle schema (use same pattern as existing items/categories tables).
+
+    5. Write `tests/services/thread.service.test.ts` with failing tests covering all behaviors listed above. Follow the pattern from `tests/services/item.service.test.ts`. Each test uses `createTestDb()` for isolation.
+
+    **GREEN phase:**
+
+    6. Implement `src/server/services/thread.service.ts` following the DI pattern from item.service.ts (db as first param with prodDb default). Functions: getAllThreads (with subquery aggregates for candidateCount and price range), getThreadWithCandidates (with candidate+category join), createThread, updateThread, deleteThread (with image cleanup collection), createCandidate, updateCandidate, deleteCandidate, resolveThread (transactional: validate thread is active + candidate belongs to thread, insert into items from candidate data, update thread status to "resolved" and set resolvedCandidateId). On resolution, if candidate's categoryId no longer exists, fall back to categoryId=1 (Uncategorized). On resolution, if candidate has imageFilename, copy the file to a new filename so the item has an independent image copy.

+    All tests must pass after implementation.

+  </behavior>
+  <action>
+    **RED phase first:**
+
+    1. Write `tests/routes/threads.test.ts` following the pattern from `tests/routes/items.test.ts`. Use `createTestDb()`, inject test DB via Hono context middleware (`c.set("db", testDb)`), and use `app.request()` for integration tests. Cover all behaviors above.
+
+    **GREEN phase:**
+
+    2. Create `src/server/routes/threads.ts` as a Hono app. Follow the exact pattern from `src/server/routes/items.ts`:
+       - Use `zValidator("json", schema)` for request body validation
+       - Get DB from `c.get("db") ?? prodDb` for testability
+       - Thread CRUD: GET / (with optional ?includeResolved query param), POST /, GET /:id, PUT /:id, DELETE /:id
+       - Candidate CRUD nested under thread: POST /:id/candidates (with image upload support via formData, same pattern as items), PUT /:threadId/candidates/:candidateId, DELETE /:threadId/candidates/:candidateId (with image file cleanup)
+       - Resolution: POST /:id/resolve with resolveThreadSchema validation
+       - Return appropriate status codes (201 for creation, 200 for success, 400 for validation/business errors, 404 for not found)
+
+    3. Mount routes in `src/server/index.ts`: `app.route("/api/threads", threadRoutes)` alongside existing routes.
+
+    For candidate image upload: follow the same pattern as the items image upload route. Candidates need a POST endpoint that accepts multipart form data with an optional image file. Use the same file validation (type/size) and storage pattern.

+# Phase 2 Plan 01: Thread Backend API Summary
+
+**Thread and candidate CRUD API with transactional resolution that atomically creates collection items from winning candidates using Drizzle transactions**
+
+## Performance
+
+- **Duration:** 5 min
+- **Started:** 2026-03-15T10:34:32Z
+- **Completed:** 2026-03-15T10:39:24Z
+- **Tasks:** 2
+- **Files modified:** 9
+
+## Accomplishments
+- Full thread CRUD (create, read, update, delete) with cascading candidate cleanup
+- Full candidate CRUD with all item-compatible fields (name, weight, price, category, notes, productUrl, image)
+- Thread list returns aggregate metadata (candidateCount, minPriceCents, maxPriceCents) via correlated subqueries
+- Transactional thread resolution: atomically creates collection item from candidate data and archives thread
+- 33 tests (19 unit + 14 integration) all passing with zero regressions on existing 30 Phase 1 tests
+
+## Task Commits
+
+Each task was committed atomically (TDD: RED then GREEN):
+
+1. **Task 1: Schema, shared schemas, test helper, and service layer**
+   - `e146eea` (test) - RED: failing tests for thread service
+   - `1a8b91e` (feat) - GREEN: implement thread service
+2. **Task 2: Thread API routes with integration tests**
+   - `37c9999` (test) - RED: failing integration tests for thread routes
+   - `add3e33` (feat) - GREEN: implement thread routes and mount
+
+## Files Created/Modified
+- `src/db/schema.ts` - Added threads and threadCandidates table definitions
+- `src/shared/schemas.ts` - Added Zod schemas for thread/candidate/resolve validation
+- `src/shared/types.ts` - Added Thread, ThreadCandidate, and related input types
+- `src/server/services/thread.service.ts` - Thread and candidate business logic with resolution transaction
+- `src/server/routes/threads.ts` - Hono API routes for threads and candidates
+- `src/server/index.ts` - Mounted threadRoutes at /api/threads
+- `tests/helpers/db.ts` - Added threads and thread_candidates table creation
+- `tests/services/thread.service.test.ts` - 19 unit tests for thread service
+- `tests/routes/threads.test.ts` - 14 integration tests for thread API
+
+## Decisions Made
+- Used raw SQL table.column references in Drizzle `sql` template literals for correlated subqueries (interpolated column objects bind as parameters, not column references)
+- Thread deletion collects candidate image filenames before cascade delete to enable filesystem cleanup
+- Resolution validates categoryId existence and falls back to Uncategorized (id=1) to handle deleted categories
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] Fixed correlated subquery column reference in getAllThreads**
+- **Found during:** Task 1 (GREEN phase)
+- **Issue:** Drizzle `sql` template literal with `${threads.id}` binds as a parameter value, not a SQL column reference, causing COUNT to return 1 instead of correct count
+- **Fix:** Changed to raw SQL reference `threads.id` instead of interpolated `${threads.id}` in correlated subqueries
+- **Files modified:** src/server/services/thread.service.ts
+- **Verification:** candidateCount returns correct values in tests
+- **Committed in:** 1a8b91e (Task 1 GREEN commit)
+
+---
+
+**Total deviations:** 1 auto-fixed (1 bug)
+**Impact on plan:** Essential fix for correct aggregate metadata. No scope creep.
+
+## Issues Encountered
+None beyond the subquery fix documented above.
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
+- Thread API fully operational, ready for frontend consumption in Plan 02
+- All endpoints follow established Phase 1 patterns (DI, Hono context, Zod validation)
+- Test infrastructure updated to support threads in all future tests

+<objective>
+Build the complete frontend for planning threads: tab navigation, thread list with cards, thread detail page with candidate grid, candidate add/edit via slide-out panel, and thread resolution flow with confirmation dialog.
+
+Purpose: Give users the full planning thread workflow in the UI -- create threads, add candidates, compare them visually, and resolve by picking a winner.
+
+Output: Fully interactive thread planning UI that consumes the API from Plan 01.

+  <action>
+    1. **Create `src/client/hooks/useThreads.ts`:** TanStack Query hooks following the useItems pattern.
+       - `useThreads(includeResolved = false)`: GET /api/threads, queryKey: ["threads", { includeResolved }]
+       - `useThread(threadId: number | null)`: GET /api/threads/:id, queryKey: ["threads", threadId], enabled when threadId != null
+       - `useCreateThread()`: POST /api/threads, onSuccess invalidates ["threads"]
+       - `useUpdateThread()`: PUT /api/threads/:id, onSuccess invalidates ["threads"]
+       - `useDeleteThread()`: DELETE /api/threads/:id, onSuccess invalidates ["threads"]
+       - `useResolveThread()`: POST /api/threads/:id/resolve, onSuccess invalidates ["threads"], ["items"], AND ["totals"] (critical for cross-tab freshness)
+
+    2. **Create `src/client/hooks/useCandidates.ts`:** TanStack Query mutation hooks.
+       - `useCreateCandidate(threadId: number)`: POST /api/threads/:id/candidates (use apiUpload for form data with optional image), onSuccess invalidates ["threads", threadId] and ["threads"] (list needs updated candidate count)
+       - `useUpdateCandidate(threadId: number)`: PUT endpoint, onSuccess invalidates ["threads", threadId]
+       - `useDeleteCandidate(threadId: number)`: DELETE endpoint, onSuccess invalidates ["threads", threadId] and ["threads"]
+
+    3. **Extend `src/client/stores/uiStore.ts`:** Add thread-specific UI state alongside existing item state. Add:
+       - `candidatePanelMode: "closed" | "add" | "edit"` (separate from item panelMode)
+       - `editingCandidateId: number | null`
+       - `confirmDeleteCandidateId: number | null`
+       - `resolveThreadId: number | null` and `resolveCandidateId: number | null` (for resolution confirm dialog)
+       - Actions: `openCandidateAddPanel()`, `openCandidateEditPanel(id)`, `closeCandidatePanel()`, `openConfirmDeleteCandidate(id)`, `closeConfirmDeleteCandidate()`, `openResolveDialog(threadId, candidateId)`, `closeResolveDialog()`
+       - Keep all existing item state unchanged.
+
+    4. **Create `src/client/components/ThreadTabs.tsx`:** Tab switcher component.
+       - Two tabs: "My Gear" and "Planning"
+       - Accept `active: "gear" | "planning"` and `onChange: (tab) => void` props
+       - Clean, minimal styling consistent with the app. Underline/highlight active tab.
+
+    5. **Create `src/client/components/ThreadCard.tsx`:** Card for thread list.
+       - Props: id, name, candidateCount, minPriceCents, maxPriceCents, createdAt, status
+       - Card layout matching ItemCard visual pattern (same rounded corners, shadows, padding)
+       - Name displayed prominently
+       - Pill/chip tags for: candidate count (e.g. "3 candidates"), creation date (formatted), price range (e.g. "$50-$120" or "No prices" if null)
+       - Click navigates to thread detail: `navigate({ to: "/threads/$threadId", params: { threadId: String(id) } })`
+       - Visual distinction for resolved threads (muted/grayed)
+
+    6. **Refactor `src/client/routes/index.tsx`:** Transform from CollectionPage into tabbed HomePage.
+       - Add `validateSearch` with `z.object({ tab: z.enum(["gear", "planning"]).catch("gear") })`
+       - Render ThreadTabs at the top
+       - When tab="gear": render existing collection content (extract into a CollectionView section or keep inline)
+       - When tab="planning": render PlanningView with thread list
+       - PlanningView shows: thread cards in a grid, "Create Thread" button (inline input or small form -- use a simple text input + button above the grid), empty state if no threads ("No planning threads yet. Start one to research your next purchase.")
+       - Toggle for "Show archived threads" that passes includeResolved to useThreads
+       - The FAB (floating add button) in __root.tsx should be context-aware: on gear tab it opens add item panel, on planning tab it could create a thread (or just hide -- use discretion)

+  <action>
+    1. **Create `src/client/components/CandidateCard.tsx`:** Card for candidates within a thread.
+       - Same visual style as ItemCard (same card shape, shadows, tag chips)
+       - Props: id, name, weightGrams, priceCents, categoryName, categoryEmoji, imageFilename, threadId
+       - Display: name, weight (formatted in g/kg), price (formatted in dollars from cents), category chip with emoji
+       - Image display if imageFilename present (use /uploads/ path)
+       - Edit button (opens candidate edit panel via uiStore)
+       - Delete button (opens confirm delete dialog via uiStore)
+       - "Pick as Winner" button -- a distinct action button (e.g. a crown/trophy icon or "Pick Winner" text button). Clicking opens the resolve confirmation dialog via `openResolveDialog(threadId, candidateId)`.
+       - Only show "Pick as Winner" when the thread is active (not resolved)
+
+    2. **Create `src/client/components/CandidateForm.tsx`:** Form for adding/editing candidates.
+       - Structurally similar to ItemForm but uses candidate hooks (useCreateCandidate, useUpdateCandidate)
+       - Same fields: name (required), weight (in grams, displayed as user-friendly input), price (in dollars, converted to cents for API), category (reuse CategoryPicker), notes, product URL, image upload (reuse ImageUpload component)
+       - mode="add": creates candidate via useCreateCandidate
+       - mode="edit": loads candidate data, updates via useUpdateCandidate
+       - On success: closes panel via closeCandidatePanel()
+       - Dollar-to-cents conversion on submit (same as ItemForm pattern)
+
+    3. **Create `src/client/routes/threads/$threadId.tsx`:** Thread detail page.
+       - File-based route using `createFileRoute("/threads/$threadId")`
+       - Parse threadId from route params
+       - Use `useThread(threadId)` to fetch thread with candidates
+       - Header: thread name, back link to `/?tab=planning`, thread status badge
+       - If thread is active: "Add Candidate" button that opens candidate add panel
+       - Candidate grid: same responsive grid as collection (1 col mobile, 2 md, 3 lg) using CandidateCard
+       - Empty state: "No candidates yet. Add your first candidate to start comparing."
+       - If thread is resolved: show which candidate won (highlight the winning candidate or show a banner)
+       - Loading and error states
+
+    4. **Update `src/client/routes/__root.tsx`:** Make the root layout handle both item and candidate panels/dialogs.
+       - Add a second SlideOutPanel instance for candidates (controlled by candidatePanelMode from uiStore). Title: "Add Candidate" or "Edit Candidate".
+       - Render CandidateForm inside the candidate panel.
+       - Add a resolution ConfirmDialog: when resolveThreadId is set in uiStore, show "Pick [candidate name] as winner? This will add it to your collection." On confirm, call useResolveThread mutation, on success close dialog and navigate back to `/?tab=planning`. On cancel, close dialog.
+       - Add a candidate delete ConfirmDialog: when confirmDeleteCandidateId is set, show delete confirmation. On confirm, call useDeleteCandidate.
+       - Keep existing item panel and delete dialog unchanged.
+       - The existing FAB should still work on the gear tab. On the threads detail page, the "Add Candidate" button handles adding, so the FAB can remain item-focused or be hidden on non-index routes.

+# Phase 2 Plan 02: Thread Frontend UI Summary
+
+**Tabbed home page with thread list cards, candidate grid detail view, slide-out candidate CRUD, and resolution flow that adds winners to the collection**
+
+## Performance
+
+- **Duration:** 4 min
+- **Started:** 2026-03-15T10:42:22Z
+- **Completed:** 2026-03-15T10:46:26Z
+- **Tasks:** 2
+- **Files modified:** 10
+
+## Accomplishments
+- Tabbed home page switching between My Gear collection and Planning thread list
+- Thread cards displaying name, candidate count, creation date, and price range chips
+- Thread detail page with candidate card grid matching ItemCard visual style
+- Candidate add/edit via slide-out panel with all item fields (name, weight, price, category, notes, URL, image)
+- Resolution confirmation dialog that picks winner, creates collection item, and archives thread
+- 63 existing tests still pass with zero regressions
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Hooks, store, tab navigation, and thread list** - `a9d624d` (feat)
+2. **Task 2: Thread detail page with candidate CRUD and resolution flow** - `7d043a8` (feat)
+
+## Files Created/Modified
+- `src/client/hooks/useThreads.ts` - TanStack Query hooks for thread CRUD and resolution
+- `src/client/hooks/useCandidates.ts` - TanStack Query mutation hooks for candidate CRUD
+- `src/client/stores/uiStore.ts` - Extended with candidate panel and resolve dialog state
+- `src/client/components/ThreadTabs.tsx` - Tab switcher with active underline indicator
+- `src/client/components/ThreadCard.tsx` - Thread list card with candidate count and price range chips
+- `src/client/components/CandidateCard.tsx` - Candidate card with edit, delete, and pick winner actions
+- `src/client/components/CandidateForm.tsx` - Candidate form with dollar-to-cents conversion
+- `src/client/routes/index.tsx` - Refactored to tabbed HomePage with CollectionView and PlanningView
+- `src/client/routes/threads/$threadId.tsx` - Thread detail page with candidate grid
+- `src/client/routes/__root.tsx` - Added candidate panel, delete dialog, and resolve dialog
+
+## Decisions Made
+- Tab navigation uses URL search params (?tab=gear|planning) for shareable/bookmarkable URLs
+- Candidate panel is a separate SlideOutPanel instance with independent state in uiStore
+- Resolution invalidates threads, items, and totals queries to keep cross-tab data fresh
+- FAB hidden on thread detail pages to avoid confusion between item add and candidate add
+- useMatchRoute detects thread detail page in root layout for candidate panel context
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+None.
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
+- Full thread planning workflow operational end-to-end
+- Thread and candidate UI consumes all API endpoints from Plan 01
+- Ready for Phase 3 (Setups and Dashboard) which may reference threads for impact preview

+    Verify the complete planning threads feature in the browser.
+
+    What was built: Tab navigation between My Gear and Planning views, thread CRUD with card-based list, candidate CRUD with slide-out panel, and thread resolution flow with confirmation dialog.
+
+    Start the dev server if not running: `bun run dev`
+    Open http://localhost:5173
+
+    **1. Tab Navigation (THRD-01)**
+    - Verify "My Gear" and "Planning" tabs are visible
+    - Click "Planning" tab -- URL should update to /?tab=planning
+    - Click "My Gear" tab -- should show your gear collection
+    - Verify top navigation bar is always visible
+
+    **2. Thread Creation (THRD-01)**
+    - On the Planning tab, create a new thread (e.g. "Helmet")
+    - Verify it appears as a card in the thread list
+    - Card should show: name, "0 candidates", creation date
+    - Create a second thread to verify list ordering (most recent first)
+
+    **3. Candidate Management (THRD-02, THRD-03)**
+    - Click a thread card to open thread detail page
+    - Verify back navigation to Planning tab works
+    - Add a candidate via slide-out panel with: name, weight, price, category, notes, product URL
+    - Verify candidate appears as a card in the grid
+    - Add 2-3 more candidates with different prices
+    - Verify the thread card on the list page shows updated candidate count and price range
+    - Edit a candidate (change price or name) -- verify changes saved
+    - Delete a candidate -- verify confirmation dialog and removal
+
+    **4. Thread Resolution (THRD-04)**
+    - On a thread with multiple candidates, click "Pick Winner" on one
+    - Verify confirmation dialog: "Pick [X] as winner? This will add it to your collection."
+    - Confirm the resolution
+    - Verify thread disappears from active thread list
+    - Toggle "Show archived" -- verify resolved thread appears (visually distinct)
+    - Switch to "My Gear" tab -- verify the winning candidate appears as a new collection item with correct data
+
+    **5. Visual Consistency**
+    - Thread cards match the visual style of item cards (same shadows, rounded corners)
+    - Candidate cards match item card style
+    - Pill/chip tags are consistent with existing tag pattern
+    - Slide-out panel for candidates looks like the item panel
+    - Empty states are present and helpful

+# Phase 2: Planning Threads - Context
+
+**Gathered:** 2026-03-15
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+Purchase research workflow: create planning threads, add candidate products, compare them, and resolve a thread by picking a winner that moves into the collection. No setups, no dashboard, no impact preview — those are later phases or v2.
+
+</domain>
+
+<decisions>
+## Implementation Decisions
+
+### Thread List View
+- Card-based layout, same visual pattern as collection items
+- Thread card shows: name prominent, then pill/chip tags for candidate count, creation date, price range
+- Flat list, most recent first (no grouping)
+- Resolved/archived threads hidden by default with a toggle to show them
+
+### Candidate Display & Management
+- Candidates displayed as card grid within a thread (same card style as collection items)
+- Slide-out panel for adding/editing candidates (reuses existing SlideOutPanel component)
+- Candidates share the exact same fields as collection items: name, weight, price, category, notes, product link, image
+- Same data shape means resolution is seamless — candidate data maps directly to a collection item
+
+### Thread Resolution Flow
+- Picking a winner auto-creates a collection item from the candidate's data (no review/edit step)
+- Confirmation dialog before resolving ("Pick [X] as winner? This will add it to your collection.")
+- After resolution, thread is archived (removed from active list, kept in history)
+- Confirmation dialog reuses the existing ConfirmDialog component pattern
+
+### Navigation
+- Tab within the collection page: "My Gear" | "Planning" tabs
+- Top navigation bar always visible for switching between major sections
+- Thread list and collection share the same page with tab-based switching
+
+### Claude's Discretion
+- Exact "pick winner" UX (button on card vs thread-level action)
+- Thread detail page layout (how the thread view is structured beyond the card grid)
+- Empty state for threads (no threads yet) and empty thread (no candidates yet)
+- How the tab switching integrates with TanStack Router (query params vs nested routes)
+- Thread card image (first candidate's image, thread-specific image, or none)
+
+</decisions>
+
+<specifics>
+## Specific Ideas
+
+- Visual consistency is important — threads and candidates should look and feel like the collection, not a separate app
+- Pill/chip tag pattern carries over: candidate count, date, price range displayed as compact tags
+- The slide-out panel pattern from Phase 1 should be reused directly for candidate add/edit
+- Thread resolution is a one-step action: confirm → item appears in collection, thread archived
+
+</specifics>
+
+<code_context>
+## Existing Code Insights
+
+### Reusable Assets
+- `SlideOutPanel.tsx`: Right-side slide panel — reuse for candidate add/edit
+- `ConfirmDialog.tsx`: Confirmation modal — reuse for resolution confirmation
+- `ItemCard.tsx`: Card component with tag chips — pattern reference for thread/candidate cards
+- `ItemForm.tsx`: Form with category picker — candidate form shares the same fields
+- `CategoryPicker.tsx`: ARIA combobox — reuse for candidate category selection
+- `ImageUpload.tsx`: Image upload component — reuse for candidate images
+- `TotalsBar.tsx`: Sticky totals — could adapt for thread-level candidate totals
+
+### Established Patterns
+- Service layer with DB injection for testability (item.service.ts, category.service.ts)
+- Hono routes with Zod validation via @hono/zod-validator
+- TanStack Query hooks for data fetching (useItems, useCategories, useTotals)
+- Zustand store for UI state (uiStore.ts)
+- API client utilities (apiGet, apiPost, apiPut, apiDelete, apiUpload)
+- Shared Zod schemas in src/shared/schemas.ts
+- Weight stored in grams, price in cents (integer math)
+
+### Integration Points
+- Database: Need new tables for threads and thread_candidates (src/db/schema.ts)
+- Shared schemas: Need thread and candidate Zod schemas (src/shared/schemas.ts)
+- Server: New routes mounted in src/server/index.ts
+- Client: New route/tab integrated via TanStack Router
+- Resolution creates items via existing item.service.ts createItem function
+
+</code_context>
+
+<deferred>
+## Deferred Ideas
+
+- Linking existing collection items as reference candidates in a thread — nice-to-have, not v1
+- Side-by-side comparison view (columns instead of cards) — could be v2 enhancement (THRD-05)
+- Status tracking on candidates (researching → ordered → arrived) — v2 (THRD-06)
+- Impact preview showing how a candidate affects setup weight/cost — v2 (THRD-08)

+# Phase 2: Planning Threads - Research
+
+**Researched:** 2026-03-15
+**Domain:** Planning thread CRUD, candidate management, thread resolution with collection integration
+**Confidence:** HIGH
+
+## Summary
+
+Phase 2 extends the established Phase 1 stack (Hono + Drizzle + React + TanStack Router/Query) with two new database tables (`threads` and `thread_candidates`), corresponding service layers, API routes, and frontend components. The core architectural challenge is the thread resolution flow: when a user picks a winning candidate, the system must atomically create a collection item from the candidate's data and archive the thread.
+
+The existing codebase provides strong reuse opportunities. Candidates share the exact same fields as collection items (name, weight, price, category, notes, product link, image), so the `ItemForm`, `ItemCard`, `SlideOutPanel`, `ConfirmDialog`, `CategoryPicker`, and `ImageUpload` components can all be reused or lightly adapted. The service layer pattern (DB injection, Drizzle queries) and API route pattern (Hono + Zod validation) are well-established from Phase 1 and should be replicated exactly.
+
+Navigation is tab-based: "My Gear" and "Planning" tabs within the same page structure. TanStack Router supports this via either search params or nested routes. The thread list is the "Planning" tab; clicking a thread navigates to a thread detail view showing its candidates.
+
+**Primary recommendation:** Follow Phase 1 patterns exactly. New tables for threads and candidates, new service/route/hook layers mirroring items. Resolution is a single transactional operation in the thread service that creates an item and archives the thread.
+
+<user_constraints>
+
+## User Constraints (from CONTEXT.md)
+
+### Locked Decisions
+- Card-based layout, same visual pattern as collection items
+- Thread card shows: name prominent, then pill/chip tags for candidate count, creation date, price range
+- Flat list, most recent first (no grouping)
+- Resolved/archived threads hidden by default with a toggle to show them
+- Candidates displayed as card grid within a thread (same card style as collection items)
+- Slide-out panel for adding/editing candidates (reuses existing SlideOutPanel component)
+- Candidates share the exact same fields as collection items: name, weight, price, category, notes, product link, image
+- Same data shape means resolution is seamless -- candidate data maps directly to a collection item

+- Confirmation dialog before resolving ("Pick [X] as winner? This will add it to your collection.")
+- After resolution, thread is archived (removed from active list, kept in history)
+- Confirmation dialog reuses the existing ConfirmDialog component pattern
+- Tab within the collection page: "My Gear" | "Planning" tabs
+- Top navigation bar always visible for switching between major sections
+- Thread list and collection share the same page with tab-based switching
+
+### Claude's Discretion
+- Exact "pick winner" UX (button on card vs thread-level action)
+- Thread detail page layout (how the thread view is structured beyond the card grid)
+- Empty state for threads (no threads yet) and empty thread (no candidates yet)
+- How the tab switching integrates with TanStack Router (query params vs nested routes)
+- Thread card image (first candidate's image, thread-specific image, or none)
+
+### Deferred Ideas (OUT OF SCOPE)
+- Linking existing collection items as reference candidates in a thread -- nice-to-have, not v1
+- Side-by-side comparison view (columns instead of cards) -- could be v2 enhancement (THRD-05)
+- Status tracking on candidates (researching -> ordered -> arrived) -- v2 (THRD-06)

+
+## Phase Requirements
+
+| ID | Description | Research Support |
+|----|-------------|-----------------|
+| THRD-01 | User can create a planning thread with a name | New `threads` table, thread service `createThread()`, POST /api/threads endpoint, thread creation UI (inline input or slide-out) |
+| THRD-02 | User can add candidate products to a thread with weight, price, notes, and product link | New `thread_candidates` table with same fields as items + threadId FK, candidate service, POST /api/threads/:id/candidates, reuse ItemForm with minor adaptations |
+| THRD-03 | User can edit and remove candidates from a thread | PUT/DELETE /api/threads/:threadId/candidates/:id, reuse SlideOutPanel + adapted ItemForm for edit, ConfirmDialog pattern for delete |
+| THRD-04 | User can resolve a thread by picking a winner, which moves to their collection | `resolveThread()` service function: transactionally create item from candidate data + set thread status to "resolved", ConfirmDialog for confirmation, cache invalidation for both threads and items queries |
+

+```
+
+### Pattern 1: Database Schema for Threads and Candidates
+
+**What:** Two new tables -- `threads` for the planning thread metadata and `thread_candidates` for candidate products within a thread. Candidates mirror the items table structure for seamless resolution.
+
+**Why this shape:** Candidates have the exact same fields as items (per CONTEXT.md locked decision). This makes resolution trivial: copy candidate fields to create a new item. The `status` field on threads supports the active/resolved lifecycle.
+
+```typescript
+// Addition to src/db/schema.ts
+export const threads = sqliteTable("threads", {
+  id: integer("id").primaryKey({ autoIncrement: true }),
+  name: text("name").notNull(),
+  status: text("status").notNull().default("active"), // "active" | "resolved"
+  resolvedCandidateId: integer("resolved_candidate_id"), // FK set on resolution
+  createdAt: integer("created_at", { mode: "timestamp" }).notNull()
+    .$defaultFn(() => new Date()),
+  updatedAt: integer("updated_at", { mode: "timestamp" }).notNull()
+    .$defaultFn(() => new Date()),
+});
+
+export const threadCandidates = sqliteTable("thread_candidates", {
+  id: integer("id").primaryKey({ autoIncrement: true }),
+  threadId: integer("thread_id").notNull()
+    .references(() => threads.id, { onDelete: "cascade" }),
+  name: text("name").notNull(),
+  weightGrams: real("weight_grams"),
+  priceCents: integer("price_cents"),
+  categoryId: integer("category_id").notNull()
+    .references(() => categories.id),
+  notes: text("notes"),
+  productUrl: text("product_url"),
+  imageFilename: text("image_filename"),
+  createdAt: integer("created_at", { mode: "timestamp" }).notNull()
+    .$defaultFn(() => new Date()),
+  updatedAt: integer("updated_at", { mode: "timestamp" }).notNull()
+    .$defaultFn(() => new Date()),
+});
+```
+
+**Key decisions:**
+- `onDelete: "cascade"` on threadId FK: deleting a thread removes its candidates (threads are self-contained units)
+- `resolvedCandidateId` on threads: records which candidate won (for display in archived view)
+- `status` as text, not boolean: allows future states without migration (though only "active"/"resolved" for v1)
+- Candidate fields exactly mirror items fields: enables direct data copy on resolution
+
+### Pattern 2: Thread Resolution as Atomic Transaction
+
+**What:** Resolving a thread is a single transactional operation: create a collection item from the winning candidate's data, then set the thread status to "resolved" and record the winning candidate ID.
+
+**Why transaction:** If either step fails, neither should persist. A resolved thread without the corresponding item (or vice versa) would be an inconsistent state.
+
+```typescript
+// In thread.service.ts
+export function resolveThread(db: Db = prodDb, threadId: number, candidateId: number) {
+  return db.transaction(() => {
+    // 1. Get the candidate data
+    const candidate = db.select().from(threadCandidates)
+      .where(eq(threadCandidates.id, candidateId))
+      .get();
+    if (!candidate) return { success: false, error: "Candidate not found" };
+    if (candidate.threadId !== threadId) return { success: false, error: "Candidate not in thread" };
+
+    // 2. Check thread is active
+    const thread = db.select().from(threads)
+      .where(eq(threads.id, threadId))
+      .get();
+    if (!thread || thread.status !== "active") return { success: false, error: "Thread not active" };
+
+    // 3. Create collection item from candidate data
+    const newItem = db.insert(items).values({
+      name: candidate.name,
+      weightGrams: candidate.weightGrams,
+      priceCents: candidate.priceCents,
+      categoryId: candidate.categoryId,
+      notes: candidate.notes,
+      productUrl: candidate.productUrl,
+      imageFilename: candidate.imageFilename,
+    }).returning().get();
+
+    // 4. Archive the thread
+    db.update(threads).set({
+      status: "resolved",
+      resolvedCandidateId: candidateId,
+      updatedAt: new Date(),
+    }).where(eq(threads.id, threadId)).run();
+
+    return { success: true, item: newItem };
+  });
+}
+```
+
+### Pattern 3: Tab Navigation with TanStack Router
+
+**What:** The collection and planning views share the same page with tab switching. Use search params (`?tab=planning`) for tab state -- this keeps a single route file and avoids unnecessary nesting.
+
+**Why search params over nested routes:** Tabs are lightweight view switches, not distinct pages with their own data loading. Search params are simpler and keep the URL shareable.
+
+```typescript
+// In src/client/routes/index.tsx
+import { createFileRoute } from "@tanstack/react-router";
+import { z } from "zod";
+
+const searchSchema = z.object({
+  tab: z.enum(["gear", "planning"]).catch("gear"),
+});
+
+export const Route = createFileRoute("/")({
+  validateSearch: searchSchema,
+  component: HomePage,
+});
+
+function HomePage() {
+  const { tab } = Route.useSearch();
+  const navigate = Route.useNavigate();
+
+  return (
+    <div>
+      <TabSwitcher
+        active={tab}
+        onChange={(t) => navigate({ search: { tab: t } })}
+      />
+      {tab === "gear" ? <CollectionView /> : <PlanningView />}
+    </div>
+  );
+}
+```
+
+**Thread detail view:** When clicking a thread card, navigate to `/threads/$threadId` (a separate file-based route). This is a distinct page, not a tab -- it shows the thread's candidates.
+
+```
+src/client/routes/
+  index.tsx              # Home with tabs (gear/planning)
+  threads/
+    $threadId.tsx         # Thread detail: shows candidates
+```
+
+### Pattern 4: Reusing ItemForm for Candidates
+
+**What:** The candidate form shares the same fields as the item form. Rather than duplicating, adapt ItemForm to accept a `variant` prop or create a thin CandidateForm wrapper that uses the same field layout.
+
+**Recommended approach:** Create a `CandidateForm` that is structurally similar to `ItemForm` but posts to the candidate API endpoint. The form fields (name, weight, price, category, notes, productUrl, image) are identical.
+
+**Why not directly reuse ItemForm:** The form currently calls `useCreateItem`/`useUpdateItem` hooks internally and closes the panel via `useUIStore`. The candidate form needs different hooks and different store actions. A new component with the same field layout is cleaner than over-parameterizing ItemForm.
+
+### Anti-Patterns to Avoid
+
+- **Duplicating candidate data on resolution:** Copy candidate fields to a new item row. Do NOT try to "move" the candidate row or create a foreign key from items to candidates. The item should be independent once created.
+- **Deleting thread on resolution:** Archive (set status="resolved"), do not delete. Users need to see their decision history.
+- **Shared mutable state between tabs:** Each tab's data (items vs threads) should use separate TanStack Query keys. Tab switching should not trigger unnecessary refetches.
+- **Over-engineering the ConfirmDialog:** The existing ConfirmDialog is hardcoded to item deletion. For thread resolution, create a new `ResolveDialog` component (or make a generic ConfirmDialog). Do not try to make the existing ConfirmDialog handle both deletion and resolution through complex state.
+
+## Don't Hand-Roll
+
+| Problem | Don't Build | Use Instead | Why |
+|---------|-------------|-------------|-----|
+| Tab routing state | Manual useState for tabs | TanStack Router search params with `validateSearch` | URL-shareable, back-button works, type-safe |
+| Atomic resolution | Manual multi-step API calls | Drizzle `db.transaction()` | Guarantees consistency: either both item creation and thread archival succeed, or neither does |
+| Cache invalidation on resolution | Manual refetch calls | TanStack Query `invalidateQueries` for both `["items"]` and `["threads"]` keys | Ensures all views are fresh after resolution |
+| Price range display on thread cards | Custom min/max computation in component | SQL aggregate in the query (or compute from loaded candidates) | Keep computation close to data source |
+
+**Key insight:** Resolution is the only genuinely new pattern in this phase. Everything else (CRUD services, Hono routes, TanStack Query hooks, slide-out panels) is a direct replication of Phase 1 patterns with different table/entity names.
+
+## Common Pitfalls
+
+### Pitfall 1: Orphaned Candidate Images on Thread Delete
+**What goes wrong:** Deleting a thread cascades to delete candidates in the DB, but their uploaded images remain on disk.
+**Why it happens:** CASCADE handles DB cleanup but not filesystem cleanup.
+**How to avoid:** Before deleting a thread, query all its candidates, collect imageFilenames, delete the thread (cascade handles DB), then unlink image files. Wrap file cleanup in try/catch.
+**Warning signs:** Orphaned files in uploads/ directory.
+
+### Pitfall 2: Resolution Creates Item with Wrong Category
+**What goes wrong:** Candidate references a categoryId that was deleted between candidate creation and resolution.
+**Why it happens:** Category deletion reassigns items to Uncategorized (id=1) but does NOT reassign candidates.
+**How to avoid:** In the resolution transaction, verify the candidate's categoryId still exists. If not, fall back to categoryId=1 (Uncategorized). Alternatively, add the same FK constraint behavior to candidates.
+**Warning signs:** FK constraint violation on resolution INSERT.
+
+### Pitfall 3: Image File Sharing Between Candidate and Resolved Item
+**What goes wrong:** Resolution copies the candidate's `imageFilename` to the new item. If the thread is later deleted (cascade deletes candidates), the image cleanup logic might delete the file that the item still references.
+**How to avoid:** On resolution, copy the image file to a new filename (e.g., append a suffix or generate new UUID). The item gets its own independent copy. Alternatively, skip image deletion on thread/candidate delete if the filename is referenced by an item.
+**Warning signs:** Broken images on collection items that were created via thread resolution.
+
+### Pitfall 4: Stale Tab Data After Resolution
+**What goes wrong:** User resolves a thread on the Planning tab, then switches to My Gear tab and doesn't see the new item.
+**Why it happens:** Resolution mutation only invalidates `["threads"]` query key, not `["items"]` and `["totals"]`.
+**How to avoid:** Resolution mutation's `onSuccess` must invalidate ALL affected query keys: `["threads"]`, `["items"]`, `["totals"]`.
+**Warning signs:** New item only appears after manual page refresh.
+
+### Pitfall 5: Thread Detail Route Without Back Navigation
+**What goes wrong:** User navigates to `/threads/5` but has no obvious way to get back to the planning list.
+**Why it happens:** Thread detail is a separate route, and the tab bar is on the home page.
+**How to avoid:** Thread detail page should have a back link/button to `/?tab=planning`. The top navigation bar (per locked decision) should always be visible.
+**Warning signs:** User gets "stuck" on thread detail page.
+
+## Code Examples
+
+### Shared Zod Schemas for Threads and Candidates
+
+```typescript
+// Additions to src/shared/schemas.ts
+
+export const createThreadSchema = z.object({
+  name: z.string().min(1, "Thread name is required"),
+});
+
+export const updateThreadSchema = z.object({
+  name: z.string().min(1).optional(),
+});
+
+// Candidates share the same fields as items
+export const createCandidateSchema = z.object({
+  name: z.string().min(1, "Name is required"),
+  weightGrams: z.number().nonnegative().optional(),
+  priceCents: z.number().int().nonnegative().optional(),
+  categoryId: z.number().int().positive(),
+  notes: z.string().optional(),
+  productUrl: z.string().url().optional().or(z.literal("")),
+});
+
+export const updateCandidateSchema = createCandidateSchema.partial();
+
+export const resolveThreadSchema = z.object({
+  candidateId: z.number().int().positive(),
+});
+```
+
+### Thread Service Pattern (following item.service.ts)
+
+```typescript
+// src/server/services/thread.service.ts
+import { eq, desc, sql } from "drizzle-orm";
+import { threads, threadCandidates, items, categories } from "../../db/schema.ts";
+import { db as prodDb } from "../../db/index.ts";
+
+type Db = typeof prodDb;
+
+export function getAllThreads(db: Db = prodDb, includeResolved = false) {
+  const query = db
+    .select({
+      id: threads.id,
+      name: threads.name,
+      status: threads.status,
+      resolvedCandidateId: threads.resolvedCandidateId,
+      createdAt: threads.createdAt,
+      updatedAt: threads.updatedAt,
+      candidateCount: sql<number>`(
+        SELECT COUNT(*) FROM thread_candidates
+        WHERE thread_id = ${threads.id}
+      )`,
+      minPriceCents: sql<number | null>`(
+        SELECT MIN(price_cents) FROM thread_candidates
+        WHERE thread_id = ${threads.id}
+      )`,
+      maxPriceCents: sql<number | null>`(
+        SELECT MAX(price_cents) FROM thread_candidates
+        WHERE thread_id = ${threads.id}
+      )`,
+    })
+    .from(threads)
+    .orderBy(desc(threads.createdAt));
+
+  if (!includeResolved) {
+    return query.where(eq(threads.status, "active")).all();
+  }
+  return query.all();
+}
+
+export function getThreadWithCandidates(db: Db = prodDb, threadId: number) {
+  const thread = db.select().from(threads)
+    .where(eq(threads.id, threadId)).get();
+  if (!thread) return null;
+
+  const candidates = db
+    .select({
+      id: threadCandidates.id,
+      threadId: threadCandidates.threadId,
+      name: threadCandidates.name,
+      weightGrams: threadCandidates.weightGrams,
+      priceCents: threadCandidates.priceCents,
+      categoryId: threadCandidates.categoryId,
+      notes: threadCandidates.notes,
+      productUrl: threadCandidates.productUrl,
+      imageFilename: threadCandidates.imageFilename,
+      createdAt: threadCandidates.createdAt,
+      updatedAt: threadCandidates.updatedAt,
+      categoryName: categories.name,
+      categoryEmoji: categories.emoji,
+    })
+    .from(threadCandidates)
+    .innerJoin(categories, eq(threadCandidates.categoryId, categories.id))
+    .where(eq(threadCandidates.threadId, threadId))
+    .all();
+
+  return { ...thread, candidates };
+}
+```
+
+### TanStack Query Hooks for Threads
+
+```typescript
+// src/client/hooks/useThreads.ts
+import { useQuery, useMutation, useQueryClient } from "@tanstack/react-query";
+import { apiGet, apiPost, apiPut, apiDelete } from "../lib/api";
+
+export function useThreads(includeResolved = false) {
+  return useQuery({
+    queryKey: ["threads", { includeResolved }],
+    queryFn: () => apiGet(`/api/threads${includeResolved ? "?includeResolved=true" : ""}`),
+  });
+}
+
+export function useThread(threadId: number | null) {
+  return useQuery({
+    queryKey: ["threads", threadId],
+    queryFn: () => apiGet(`/api/threads/${threadId}`),
+    enabled: threadId != null,
+  });
+}
+
+export function useResolveThread() {
+  const queryClient = useQueryClient();
+  return useMutation({
+    mutationFn: ({ threadId, candidateId }: { threadId: number; candidateId: number }) =>
+      apiPost(`/api/threads/${threadId}/resolve`, { candidateId }),
+    onSuccess: () => {
+      // Invalidate ALL affected queries
+      queryClient.invalidateQueries({ queryKey: ["threads"] });
+      queryClient.invalidateQueries({ queryKey: ["items"] });
+      queryClient.invalidateQueries({ queryKey: ["totals"] });
+    },
+  });
+}
+```
+
+### Thread Routes Pattern (following items.ts)
+
+```typescript
+// src/server/routes/threads.ts
+import { Hono } from "hono";
+import { zValidator } from "@hono/zod-validator";
+import { createThreadSchema, updateThreadSchema, resolveThreadSchema,
+  createCandidateSchema, updateCandidateSchema } from "../../shared/schemas.ts";
+
+type Env = { Variables: { db?: any } };
+const app = new Hono<Env>();
+
+// Thread CRUD
+app.get("/", (c) => { /* getAllThreads */ });
+app.post("/", zValidator("json", createThreadSchema), (c) => { /* createThread */ });
+app.get("/:id", (c) => { /* getThreadWithCandidates */ });
+app.put("/:id", zValidator("json", updateThreadSchema), (c) => { /* updateThread */ });
+app.delete("/:id", (c) => { /* deleteThread with image cleanup */ });
+
+// Candidate CRUD (nested under thread)
+app.post("/:id/candidates", zValidator("json", createCandidateSchema), (c) => { /* addCandidate */ });
+app.put("/:threadId/candidates/:candidateId", zValidator("json", updateCandidateSchema), (c) => { /* updateCandidate */ });
+app.delete("/:threadId/candidates/:candidateId", (c) => { /* removeCandidate */ });
+
+// Resolution
+app.post("/:id/resolve", zValidator("json", resolveThreadSchema), (c) => { /* resolveThread */ });
+
+export { app as threadRoutes };
+```
+
+### Test Helper Update
+
+```typescript
+// Addition to tests/helpers/db.ts createTestDb()
+
+sqlite.run(`
+  CREATE TABLE threads (
+    id INTEGER PRIMARY KEY AUTOINCREMENT,
+    name TEXT NOT NULL,
+    status TEXT NOT NULL DEFAULT 'active',
+    resolved_candidate_id INTEGER,
+    created_at INTEGER NOT NULL DEFAULT (unixepoch()),
+    updated_at INTEGER NOT NULL DEFAULT (unixepoch())
+  )
+`);
+
+sqlite.run(`
+  CREATE TABLE thread_candidates (
+    id INTEGER PRIMARY KEY AUTOINCREMENT,
+    thread_id INTEGER NOT NULL REFERENCES threads(id) ON DELETE CASCADE,
+    name TEXT NOT NULL,
+    weight_grams REAL,
+    price_cents INTEGER,
+    category_id INTEGER NOT NULL REFERENCES categories(id),
+    notes TEXT,
+    product_url TEXT,
+    image_filename TEXT,
+    created_at INTEGER NOT NULL DEFAULT (unixepoch()),
+    updated_at INTEGER NOT NULL DEFAULT (unixepoch())
+  )
+`);
+```
+
+## State of the Art
+
+No new libraries or version changes since Phase 1. The entire stack is already installed and verified.
+
+| Phase 1 Pattern | Phase 2 Extension | Notes |
+|-----------------|-------------------|-------|
+| items table | threads + thread_candidates tables | Candidates mirror items schema |
+| item.service.ts | thread.service.ts | Same DI pattern, adds transaction for resolution |
+| /api/items routes | /api/threads routes | Nested candidate routes under thread |
+| useItems hooks | useThreads + useCandidates hooks | Same TanStack Query patterns |
+| ItemCard component | ThreadCard + CandidateCard | Same visual style with pill/chip tags |
+| ItemForm component | CandidateForm | Same fields, different API endpoints |
+| uiStore panel state | Extended with thread panel/dialog state | Same Zustand pattern |
+
+## Open Questions
+
+1. **Image handling on resolution**
+   - What we know: Candidate imageFilename is copied to the new item
+   - What's unclear: Should the file be duplicated on disk to prevent orphaned references?
+   - Recommendation: Copy the file to a new filename during resolution. This prevents the edge case where thread deletion removes an image still used by a collection item. The copy operation is cheap for small image files.
+
+2. **Thread deletion**
+   - What we know: Resolved threads are archived, not deleted. Active threads can be deleted.
+   - What's unclear: Should users be able to delete resolved/archived threads?
+   - Recommendation: Allow deletion of both active and archived threads with a confirmation dialog. Image cleanup required in both cases.
+
+3. **Category on thread cards**
+   - What we know: Thread cards show name, candidate count, date, price range
+   - What's unclear: Thread itself has no category -- it's a container for candidates
+   - Recommendation: Threads don't need a category. The pill tags on thread cards show: candidate count, date created, price range (min-max of candidates).

+
+Note on `resolveThread` items link: the service imports `items` directly from the schema rather than calling `item.service.ts`. This is architecturally equivalent — the transaction writes to the same `items` table. No gap.

+
+All four required IDs claimed in both plans and fully covered. No orphaned requirements found for Phase 2.
+
+### Anti-Patterns Found
+
+| File | Line | Pattern | Severity | Impact |
+|------|------|---------|----------|--------|
+| `thread.service.ts` | 50, 79, 92, 143, 156 | `return null` | Info | All are proper 404 guard early-returns, not stub implementations |
+
+No blocker or warning anti-patterns found. The `return null` instances are intentional not-found guards — the callers in `threads.ts` handle them correctly with 404 responses.
+
+### Human Verification Required
+
+#### 1. Tab Navigation and URL Sync
+
+**Test:** Open http://localhost:5173, click Planning tab, observe URL bar, then click My Gear tab. Refresh on `/?tab=planning` and confirm Planning view loads.
+**Expected:** URL updates to `/?tab=planning` on Planning tab; returns to `/?tab=gear` on My Gear; state survives refresh.
+**Why human:** TanStack Router search param behaviour and browser history interaction require a live browser.
+
+#### 2. Thread Creation Flow
+
+**Test:** On Planning tab, type a thread name and click Create. Observe the thread list.
+**Expected:** New thread card appears immediately with correct name, "0 candidates", and today's date. Input clears.
+**Why human:** Mutation optimistic/on-success re-render and card content require visual confirmation.
+
+#### 3. Candidate Slide-Out Panel
+
+**Test:** Navigate to a thread detail page, click Add Candidate. Fill all fields (name, weight, price, category, notes, URL). Submit.
+**Expected:** Panel slides in with all fields present; submitting closes the panel and the new candidate appears in the grid.
+**Why human:** Panel animation, field completeness, and grid update require visual inspection.
+
+#### 4. Resolved Thread Visibility Toggle
+
+**Test:** Resolve a thread (see test 5), then return to Planning tab. Observe thread list. Check "Show archived threads" checkbox.
+**Expected:** Resolved thread is hidden by default; checking toggle reveals it with "Resolved" badge and reduced opacity.
+**Why human:** Conditional rendering and checkbox toggle state require browser confirmation.
+
+#### 5. Resolution Flow End-to-End
+
+**Test:** On a thread detail page with multiple candidates, click "Pick Winner" on one candidate. Confirm in the dialog. Switch to My Gear tab.
+**Expected:** Confirmation dialog shows candidate name. After confirming: thread disappears from active Planning list; the candidate's data appears as a new item in My Gear without a page refresh.
+**Why human:** Cross-tab data freshness via `invalidateQueries`, dialog appearance, and post-resolution navigation require live testing.
+
+### Gaps Summary
+
+No automated gaps found. All 11 observable truths verified, all 15 artifacts exist and are substantive, all 9 key links are wired, and all 4 THRD requirements are satisfied with implementation evidence.
+
+The 5 items above require human browser verification — they cover the UI interaction layer (tab navigation, panel open/close, resolution dialog, and cross-tab data freshness) which cannot be confirmed programmatically. These are standard human-verification items for any UI feature and do not indicate implementation problems.

+<objective>
+Build the complete setup backend: database schema (setups + setup_items junction table), shared Zod schemas/types, service layer with CRUD + item sync + totals aggregation, and Hono API routes. All with TDD.
+
+Purpose: Provides the data layer and API that the frontend (Plan 02) will consume. The many-to-many junction table is the only new DB pattern in this project.
+Output: Working API at /api/setups with full test coverage.

+    tests/services/setup.service.test.ts, tests/routes/setups.test.ts
+  </files>
+  <behavior>
+    Service layer (setup.service.ts):
+    - getAllSetups: returns setups with itemCount, totalWeight (grams), totalCost (cents) via SQL subqueries
+    - getSetupWithItems: returns single setup with full item details (joined with categories), null if not found
+    - createSetup: creates setup with name, returns created setup
+    - updateSetup: updates setup name, returns updated setup, null if not found
+    - deleteSetup: deletes setup (cascade deletes setup_items), returns boolean
+    - syncSetupItems: delete-all + re-insert in transaction, accepts setupId + itemIds array
+    - removeSetupItem: removes single item from setup by setupId + itemId
+
+    API routes (setups.ts):
+    - GET /api/setups -> list all setups with aggregated totals
+    - GET /api/setups/:id -> single setup with items
+    - POST /api/setups -> create setup (validates name via createSetupSchema)
+    - PUT /api/setups/:id -> update setup name
+    - DELETE /api/setups/:id -> delete setup
+    - PUT /api/setups/:id/items -> sync setup items (validates itemIds via syncSetupItemsSchema)
+    - DELETE /api/setups/:id/items/:itemId -> remove single item from setup
+
+    Edge cases:
+    - Syncing with empty itemIds array clears all items from setup
+    - Deleting a collection item cascades removal from all setups
+    - getAllSetups returns 0 for weight/cost when setup has no items (COALESCE)
+  </behavior>
+  <implementation>
+    1. Add setups and setupItems tables to src/db/schema.ts (with cascade FKs)
+    2. Add Zod schemas (createSetupSchema, updateSetupSchema, syncSetupItemsSchema) to src/shared/schemas.ts
+    3. Add types (CreateSetup, UpdateSetup, SyncSetupItems, Setup, SetupItem) to src/shared/types.ts
+    4. Add setups and setup_items CREATE TABLE to tests/helpers/db.ts
+    5. Implement setup.service.ts following thread.service.ts pattern (db as first param with prod default)
+    6. Implement setups.ts routes following threads.ts pattern (Hono with zValidator)
+    7. Mount setupRoutes in src/server/index.ts
+    8. Use raw SQL in Drizzle sql`` for correlated subqueries in getAllSetups (per Phase 2 decision about table.column refs)

+# Phase 3 Plan 1: Setup Backend Summary
+
+**Setup CRUD API with junction table, SQL aggregation for totals, and transactional item sync**
+
+## Performance
+
+- **Duration:** 8 min
+- **Started:** 2026-03-15T11:35:17Z
+- **Completed:** 2026-03-15T11:43:11Z
+- **Tasks:** 2 (TDD RED + GREEN)
+- **Files modified:** 9
+
+## Accomplishments
+- Setup CRUD with all 7 API endpoints working
+- Junction table (setup_items) with cascade deletes on both setup and item deletion
+- SQL aggregation returning itemCount, totalWeight, totalCost via COALESCE subqueries
+- Full TDD with 24 new tests (13 service + 11 route), all 87 tests passing
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: RED - Failing tests + schema** - `1e4e74f` (test)
+2. **Task 2: GREEN - Implementation** - `0f115a2` (feat)
+
+## Files Created/Modified
+- `src/db/schema.ts` - Added setups and setupItems table definitions
+- `src/shared/schemas.ts` - Added createSetupSchema, updateSetupSchema, syncSetupItemsSchema
+- `src/shared/types.ts` - Added CreateSetup, UpdateSetup, SyncSetupItems, Setup, SetupItem types
+- `src/server/services/setup.service.ts` - Setup business logic with DB injection
+- `src/server/routes/setups.ts` - Hono API routes for all 7 setup endpoints
+- `src/server/index.ts` - Mounted setupRoutes at /api/setups
+- `tests/helpers/db.ts` - Added setups and setup_items CREATE TABLE statements
+- `tests/services/setup.service.test.ts` - 13 service unit tests
+- `tests/routes/setups.test.ts` - 11 route integration tests
+
+## Decisions Made
+- syncSetupItems uses delete-all + re-insert in transaction for simplicity over diff-based sync
+- SQL COALESCE ensures 0 returned for empty setups instead of null
+- removeSetupItem uses raw SQL WHERE clause for compound condition (setupId + itemId)
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+- Setup API complete and tested, ready for frontend consumption in Plan 02
+- Junction table pattern established for any future many-to-many relationships

+    src/client/stores/uiStore.ts
+  </files>
+  <action>
+    **1. Refactor TotalsBar to accept optional props (per CONTEXT.md decisions):**
+    - Add props: `title?: string`, `stats?: Array<{label: string, value: string}>`, `linkTo?: string`
+    - When no `stats` prop: show title only (for dashboard)
+    - When `stats` provided: render them instead of fetching global totals internally
+    - When `linkTo` provided: wrap title in `<Link to={linkTo}>` (per decision: GearBox title always links to /)
+    - Default behavior (no props): fetch global totals with useTotals() and display as before (backward compatible for collection page)
+    - Dashboard passes no linkTo (already on dashboard). All other pages pass `linkTo="/"`
+
+    **2. Move current index.tsx content to collection/index.tsx:**
+    - Create `src/client/routes/collection/index.tsx`
+    - Move the entire HomePage, CollectionView, and PlanningView content from current `index.tsx`
+    - Update route: `createFileRoute("/collection/")` with same `validateSearch` for tab param
+    - Update handleTabChange to navigate to `/collection` instead of `/`
+    - The TotalsBar in __root.tsx will automatically show global stats on this page (default behavior)
+
+    **3. Rewrite index.tsx as Dashboard (per CONTEXT.md decisions):**
+    - Three equal-width cards (grid-cols-1 md:grid-cols-3 gap-6)
+    - Collection card: shows item count, total weight, total cost. Links to `/collection`. Empty state shows "Get started"
+    - Planning card: shows active thread count. Links to `/collection?tab=planning`
+    - Setups card: shows setup count. Links to `/setups`
+    - Use `useTotals()` for collection stats, `useThreads(false)` for active threads, `useSetups()` for setup count
+    - "GearBox" title only in TotalsBar (no stats on dashboard) -- pass no stats prop
+    - Clean layout: max-w-7xl, centered, lots of whitespace
+
+    **4. Create DashboardCard.tsx component:**
+    - Props: `to: string`, `title: string`, `icon: ReactNode`, `stats: Array<{label: string, value: string}>`, `emptyText?: string`
+    - Card with hover shadow transition, rounded-xl, padding
+    - Wraps in `<Link to={to}>` for navigation
+    - Shows icon, title, stats list, and optional empty state text
+
+    **5. Create useSetups.ts hooks (follows useThreads.ts pattern exactly):**
+    - `useSetups()`: queryKey ["setups"], fetches GET /api/setups
+    - `useSetup(setupId: number | null)`: queryKey ["setups", setupId], enabled when setupId != null
+    - `useCreateSetup()`: POST /api/setups, invalidates ["setups"]
+    - `useUpdateSetup(setupId: number)`: PUT /api/setups/:id, invalidates ["setups"]
+    - `useDeleteSetup()`: DELETE /api/setups/:id, invalidates ["setups"]
+    - `useSyncSetupItems(setupId: number)`: PUT /api/setups/:id/items, invalidates ["setups"]
+    - `useRemoveSetupItem(setupId: number)`: DELETE /api/setups/:id/items/:itemId, invalidates ["setups"]
+    - Define response types inline: `SetupListItem` (with itemCount, totalWeight, totalCost) and `SetupWithItems` (with items array including category info)
+
+    **6. Update __root.tsx:**
+    - Pass route-aware props to TotalsBar based on current route matching
+    - On dashboard (`/`): no stats, no linkTo
+    - On collection (`/collection`): default behavior (TotalsBar fetches its own stats), linkTo="/"
+    - On thread detail: linkTo="/" (keep current behavior)
+    - On setups: linkTo="/"
+    - On setup detail: TotalsBar with setup-specific title and stats (will be handled by setup detail page passing context)
+    - Update FAB visibility: only show on `/collection` route when gear tab is active (not on dashboard, not on setups). Match `/collection` route instead of just hiding on thread pages
+    - Update ResolveDialog onResolved navigation: change from `{ to: "/", search: { tab: "planning" } }` to `{ to: "/collection", search: { tab: "planning" } }`
+
+    **7. Add setup-related UI state to uiStore.ts:**
+    - Add `itemPickerOpen: boolean` state
+    - Add `openItemPicker()` and `closeItemPicker()` actions
+    - Add `confirmDeleteSetupId: number | null` state with open/close actions
+
+    **8. Update useItems invalidation (Pitfall 1 from research):**
+    - In `useUpdateItem` and `useDeleteItem` mutation `onSuccess`, also invalidate `["setups"]` query key
+    - This ensures setup totals update when a collection item's weight/price changes or item is deleted
+
+    IMPORTANT: After creating route files, the TanStack Router plugin will auto-regenerate `routeTree.gen.ts`. Restart the dev server if needed.

+    - Card with rounded-xl, shadow-sm, hover:shadow-md transition
+    - Shows setup name, item count pill, formatted weight and cost
+    - Wraps in `<Link to="/setups/$setupId" params={{ setupId: String(id) }}>`
+    - Use `formatWeight` and `formatPrice` from existing `lib/formatters`
+
+    **2. Create setups list page (src/client/routes/setups/index.tsx):**
+    - Route: `createFileRoute("/setups/")`
+    - Inline name input + "Create" button at top (same pattern as thread creation in PlanningView)
+    - Uses `useSetups()` and `useCreateSetup()` hooks
+    - Grid layout: grid-cols-1 md:grid-cols-2 lg:grid-cols-3 gap-4
+    - Each setup rendered as SetupCard
+    - Empty state: icon + "No setups yet" message + "Create one to plan your loadout"
+    - Loading skeleton: 2 placeholder cards
+
+    **3. Create ItemPicker.tsx (checklist in SlideOutPanel, per CONTEXT.md decisions):**
+    - Props: `setupId: number`, `currentItemIds: number[]`, `isOpen: boolean`, `onClose: () => void`
+    - Renders inside a SlideOutPanel with title "Select Items"
+    - Fetches all collection items via `useItems()`
+    - Groups items by category with emoji headers (same grouping as CollectionView)
+    - Each item is a checkbox row: `[x] emoji ItemName (weight, price)`
+    - Pre-checks items already in the setup (from `currentItemIds`)
+    - Local state tracks toggled item IDs
+    - "Done" button at bottom calls `useSyncSetupItems(setupId)` with selected IDs, then closes
+    - Scrollable list for large collections (max-h with overflow-y-auto)
+    - "Cancel" closes without saving
+
+    **4. Create setup detail page (src/client/routes/setups/$setupId.tsx):**
+    - Route: `createFileRoute("/setups/$setupId")`
+    - Uses `useSetup(setupId)` to fetch setup with items
+    - Sticky TotalsBar override: pass setup name as title, setup-specific stats (item count, total weight, total cost)
+      - Compute totals client-side from items array (per research recommendation)
+      - Render a local TotalsBar-like sticky bar at top of the page with setup name + stats
+    - "Add Items" button opens ItemPicker via SlideOutPanel
+    - "Delete Setup" button with ConfirmDialog confirmation
+    - Item cards grouped by category using CategoryHeader + ItemCard (same visual as collection)
+    - Each ItemCard gets a small x remove button overlay (per CONTEXT.md: non-destructive, no confirmation)
+    - Per-category subtotals in CategoryHeader (weight/cost within this setup)
+    - Empty state when no items: "No items in this setup" + "Add Items" button
+    - On successful delete, navigate to `/setups`
+
+    **5. Modify ItemCard.tsx to support remove mode:**
+    - Add optional prop: `onRemove?: () => void`
+    - When `onRemove` provided, show a small x icon button in top-right corner of card
+    - x button calls `onRemove` on click (stops propagation to prevent edit panel opening)
+    - Subtle styling: small, semi-transparent, visible on hover or always visible but muted
+    - Does NOT change existing behavior when `onRemove` is not provided
+
+    IMPORTANT: Use `useRemoveSetupItem(setupId)` for the x button on cards. Use `useSyncSetupItems(setupId)` for the checklist picker "Done" action. These are separate mutations for separate UX patterns (per research: batch sync vs single remove).

+# Phase 3 Plan 2: Setup Frontend Summary
+
+**Dashboard with summary cards, setup CRUD UI with category-grouped item picker, and route-aware TotalsBar**
+
+## Performance
+
+- **Duration:** 5 min
+- **Started:** 2026-03-15T11:45:33Z
+- **Completed:** 2026-03-15T11:50:33Z
+- **Tasks:** 2
+- **Files modified:** 14
+
+## Accomplishments
+- Dashboard at / with three summary cards linking to Collection, Planning, and Setups
+- Full setup CRUD UI: list page with inline create, detail page with item management
+- ItemPicker component in SlideOutPanel for checklist-based item assignment to setups
+- Route-aware TotalsBar that shows contextual stats per page
+- Navigation restructure moving collection to /collection with GearBox title linking home
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Navigation restructure, TotalsBar refactor, and setup hooks** - `86a7a0d` (feat)
+2. **Task 2: Setup list page, detail page, and item picker** - `6709955` (feat)
+
+## Files Created/Modified
+- `src/client/routes/index.tsx` - Dashboard page with three DashboardCard components
+- `src/client/routes/collection/index.tsx` - Collection page with gear/planning tabs (moved from /)
+- `src/client/routes/setups/index.tsx` - Setup list page with inline create form and SetupCard grid
+- `src/client/routes/setups/$setupId.tsx` - Setup detail with category-grouped items, totals bar, item picker, delete
+- `src/client/routes/__root.tsx` - Route-aware TotalsBar props, FAB visibility, resolve navigation update
+- `src/client/components/TotalsBar.tsx` - Refactored to accept optional stats/linkTo/title props
+- `src/client/components/DashboardCard.tsx` - Dashboard summary card with icon, stats, empty text
+- `src/client/components/SetupCard.tsx` - Setup list card with name, item count, weight, cost
+- `src/client/components/ItemPicker.tsx` - Checklist picker in SlideOutPanel for item selection
+- `src/client/components/ItemCard.tsx` - Added optional onRemove prop for setup item removal
+- `src/client/hooks/useSetups.ts` - TanStack Query hooks for setup CRUD and item sync/remove
+- `src/client/hooks/useItems.ts` - Added setups invalidation on item update/delete
+- `src/client/stores/uiStore.ts` - Added itemPicker and confirmDeleteSetup UI state
+- `src/client/routeTree.gen.ts` - Updated with new collection/setups routes
+
+## Decisions Made
+- TotalsBar refactored with optional props rather than creating separate components per page
+- Setup detail computes totals client-side from items array (avoids extra API call)
+- ItemPicker tracks selections locally, syncs batch on Done (not per-toggle)
+- FAB restricted to /collection gear tab only (hidden on dashboard and setups)
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+- All frontend features complete, ready for visual verification in Plan 03
+- All 87 backend tests still passing
+- TypeScript compiles clean (only pre-existing warnings in CategoryPicker/OnboardingWizard)

+  <how-to-verify>
+    Start the dev server: `bun run dev`
+
+    **1. Dashboard (DASH-01):**
+    - Visit http://localhost:5173/
+    - Verify three cards: Collection (item count, weight, cost), Planning (active thread count), Setups (setup count)
+    - Verify "GearBox" title in top bar, no stats shown on dashboard
+    - Click Collection card -> navigates to /collection
+    - Click Planning card -> navigates to /collection?tab=planning
+    - Click Setups card -> navigates to /setups
+
+    **2. Navigation restructure:**
+    - At /collection: verify gear/planning tabs work as before
+    - Verify "GearBox" title in TotalsBar links back to / (dashboard)
+    - Verify floating + button only appears on /collection gear tab (not on dashboard, setups, or planning tab)
+    - Go to a thread detail page -> verify "GearBox" links back to dashboard
+
+    **3. Setup creation (SETP-01):**
+    - Navigate to /setups
+    - Create a setup named "Summer Bikepacking" using inline form
+    - Verify it appears in the list as a card
+
+    **4. Item management (SETP-02):**
+    - Click the new setup card to open detail page
+    - Click "Add Items" button
+    - Verify checklist picker opens in slide-out panel with items grouped by category
+    - Check several items, click "Done"
+    - Verify items appear on setup detail page grouped by category
+    - Click x on an item card to remove it from setup (no confirmation)
+    - Verify item disappears from setup but still exists in collection
+
+    **5. Setup totals (SETP-03):**
+    - On setup detail page, verify sticky bar shows setup name, item count, total weight, total cost
+    - Remove an item -> totals update
+    - Add items back -> totals update
+    - Go back to setups list -> verify card shows correct totals
+
+    **6. Cross-feature consistency:**
+    - Edit a collection item's weight from /collection -> check setup totals update
+    - Delete a collection item -> verify it disappears from the setup too
+    - Create a thread, resolve it -> verify dashboard Planning card count updates

+# Phase 3: Setups and Dashboard - Context
+
+**Gathered:** 2026-03-15
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+Named loadouts composed from collection items with live weight/cost totals, plus a dashboard home page with summary cards linking to collection, threads, and setups. No setup enhancements (weight classification, charts) — those are v2. No thread or collection changes beyond navigation restructure.
+
+</domain>
+
+<decisions>
+## Implementation Decisions
+
+### Setup Item Selection
+- Checklist picker in a SlideOutPanel showing all collection items
+- Items grouped by category with emoji headers (same grouping as collection view)
+- Toggle items on/off via checkboxes — "Done" button to confirm
+- Items can belong to multiple setups (shared, not exclusive)
+
+### Setup Creation
+- Inline name input + create button at top of setups list
+- Same pattern as thread creation in Phase 2 (text input + button)
+- No description field or extra metadata — just a name
+
+### Setup Display
+- Card grid layout grouped by category, reusing ItemCard component
+- Same visual pattern as collection view for consistency
+- Each item card gets a small × remove icon to remove from setup (not from collection)
+- No confirmation dialog for removal — non-destructive action
+- Per-category subtotals in CategoryHeader (weight/cost within this setup)
+
+### Setup Totals
+- Sticky bar at top of setup detail page showing setup name, item count, total weight, total cost
+- Reuses TotalsBar pattern — contextual stats for the current setup
+- Totals computed live from current item data
+
+### Dashboard Card Design
+- Three equal-width cards side by side on desktop, stacking vertically on mobile
+- Collection card: item count, total weight, total cost
+- Planning card: active thread count
+- Setups card: setup count
+- Summary stats on each card — at-a-glance overview before clicking in
+- Empty state: same cards with zeros, Collection card says "Get started"
+
+### Dashboard Page Header
+- "GearBox" title only on dashboard (stats already on cards, no redundancy)
+- No welcome message or greeting — clean and minimal
+
+### Navigation & URL Structure
+- `/` = Dashboard (three summary cards)
+- `/collection` = Gear | Planning tabs (moved from current `/`)
+- `/collection?tab=planning` = Planning tab
+- `/threads/:id` = Thread detail (unchanged)
+- `/setups` = Setups list
+- `/setups/:id` = Setup detail
+- "GearBox" title in TotalsBar is always a clickable link back to dashboard
+- No breadcrumbs or back arrows — GearBox title link is the only back navigation
+- Sub-pages show contextual stats in TotalsBar; dashboard shows title only
+
+### Claude's Discretion
+- Setup list card design (what stats/info to show per setup card beyond name and totals)
+- Exact Tailwind styling, spacing, and transitions for dashboard cards
+- Setup detail page layout specifics beyond the card grid + sticky totals
+- How the checklist picker handles a large number of items (scroll behavior)
+- Error states and loading skeletons
+
+</decisions>
+
+<specifics>
+## Specific Ideas
+
+- Dashboard should feel like a clean entry point — "GearBox" title, three cards, lots of whitespace
+- Setup detail should visually mirror the collection view (same card grid, category headers, tag chips) so it feels like a filtered subset of your gear
+- Removal × on cards should be subtle — don't clutter the visual consistency with collection
+- Thread creation pattern (inline input + button) is the reference for setup creation
+
+</specifics>
+
+<code_context>
+## Existing Code Insights
+
+### Reusable Assets
+- `SlideOutPanel.tsx`: Right-side slide panel — reuse for checklist item picker
+- `ItemCard.tsx`: Card with tag chips — reuse directly in setup detail view (add × icon variant)
+- `CategoryHeader.tsx`: Category section with emoji + subtotals — reuse in setup detail
+- `TotalsBar.tsx`: Sticky bar with stats — adapt for contextual stats per page
+- `ThreadCard.tsx`: Card with pill tags — pattern reference for setup list cards
+- `ConfirmDialog.tsx`: Confirmation modal — reuse for setup deletion
+- `ThreadTabs.tsx`: Tab component — reuse for gear/planning tabs on /collection
+
+### Established Patterns
+- Service layer with DB injection (`item.service.ts`, `thread.service.ts`)
+- Hono routes with Zod validation via `@hono/zod-validator`
+- TanStack Query hooks for data fetching
+- Zustand store for UI state (`uiStore.ts`)
+- API client utilities (`apiGet`, `apiPost`, `apiPut`, `apiDelete`)
+- Shared Zod schemas in `src/shared/schemas.ts`
+- Weight in grams, price in cents (integer math)
+- URL search params for tab state
+
+### Integration Points
+- Database: New `setups` and `setup_items` tables in `src/db/schema.ts`
+- Shared schemas: Setup Zod schemas in `src/shared/schemas.ts`
+- Server: New setup routes in `src/server/routes/`, mounted in `src/server/index.ts`
+- Client: New `/collection` and `/setups` routes, refactor current `/` to dashboard
+- TotalsBar: Needs to become route-aware (different stats per page)
+- Totals service: New setup totals endpoint or compute client-side from items

+# Phase 3: Setups and Dashboard - Research
+
+**Researched:** 2026-03-15
+**Domain:** Full-stack CRUD (Drizzle + Hono + React) with navigation restructure
+**Confidence:** HIGH
+
+## Summary
+
+Phase 3 adds two features: (1) named setups (loadouts) that compose collection items with live weight/cost totals, and (2) a dashboard home page with summary cards. The codebase has strong established patterns from Phases 1 and 2 -- database schema in Drizzle, service layer with DB injection, Hono routes with Zod validation, TanStack Query hooks, and Zustand UI state. This phase follows identical patterns with one significant difference: the many-to-many relationship between items and setups via a junction table (`setup_items`).
+
+The navigation restructure moves the current `/` (gear + planning tabs) to `/collection` and replaces `/` with a dashboard. This requires moving the existing `index.tsx` route content to a new `collection/index.tsx` route, creating new `/setups` routes, and making TotalsBar route-aware for contextual stats.
+
+**Primary recommendation:** Follow the exact thread CRUD pattern for setups (schema, service, routes, hooks, components), add a `setup_items` junction table for the many-to-many relationship, compute setup totals server-side via SQL aggregation, and restructure routes with TanStack Router file-based routing.
+
+<user_constraints>
+## User Constraints (from CONTEXT.md)
+
+### Locked Decisions
+- Setup item selection: Checklist picker in SlideOutPanel, items grouped by category with emoji headers, toggle via checkboxes, "Done" button to confirm, items shared across setups
+- Setup creation: Inline name input + create button (same pattern as thread creation)
+- Setup display: Card grid grouped by category reusing ItemCard with small x remove icon, per-category subtotals in CategoryHeader
+- Setup totals: Sticky bar at top showing setup name, item count, total weight, total cost (reuses TotalsBar pattern)
+- Dashboard cards: Three equal-width cards (Collection, Planning, Setups) side by side on desktop, stacking on mobile, with summary stats on each card
+- Dashboard header: "GearBox" title only, no welcome message
+- Navigation: `/` = Dashboard, `/collection` = Gear|Planning tabs, `/setups` = Setups list, `/setups/:id` = Setup detail
+- "GearBox" title in TotalsBar is always a clickable link back to dashboard
+- No breadcrumbs or back arrows -- GearBox title link is the only back navigation
+
+### Claude's Discretion
+- Setup list card design (stats/info per setup card beyond name and totals)
+- Exact Tailwind styling, spacing, and transitions for dashboard cards
+- Setup detail page layout specifics beyond card grid + sticky totals
+- How checklist picker handles large number of items (scroll behavior)
+- Error states and loading skeletons

+## Phase Requirements
+
+| ID | Description | Research Support |
+|----|-------------|-----------------|
+| SETP-01 | User can create named setups (e.g. "Summer Bikepacking") | Setup CRUD: schema, service, routes, hooks -- follows thread creation pattern exactly |
+| SETP-02 | User can add/remove collection items to a setup | Junction table `setup_items`, checklist picker in SlideOutPanel, batch sync endpoint |
+| SETP-03 | User can see total weight and cost for a setup | Server-side SQL aggregation via `setup_items` JOIN `items`, setup totals endpoint |
+| DASH-01 | User sees dashboard home page with cards linking to collection, threads, and setups | New `/` route with three summary cards, existing content moves to `/collection` |

+```
+
+### Pattern 1: Many-to-Many Junction Table
+**What:** `setup_items` links setups to items (items can belong to multiple setups)
+**When to use:** This is the only new DB pattern in this phase
+
+```typescript
+// In src/db/schema.ts
+export const setups = sqliteTable("setups", {
+  id: integer("id").primaryKey({ autoIncrement: true }),
+  name: text("name").notNull(),
+  createdAt: integer("created_at", { mode: "timestamp" })
+    .notNull()
+    .$defaultFn(() => new Date()),
+  updatedAt: integer("updated_at", { mode: "timestamp" })
+    .notNull()
+    .$defaultFn(() => new Date()),
+});
+
+export const setupItems = sqliteTable("setup_items", {
+  id: integer("id").primaryKey({ autoIncrement: true }),
+  setupId: integer("setup_id")
+    .notNull()
+    .references(() => setups.id, { onDelete: "cascade" }),
+  itemId: integer("item_id")
+    .notNull()
+    .references(() => items.id, { onDelete: "cascade" }),
+  addedAt: integer("added_at", { mode: "timestamp" })
+    .notNull()
+    .$defaultFn(() => new Date()),
+});
+```
+
+**Key design decisions:**
+- `onDelete: "cascade"` on both FKs: deleting a setup removes its setup_items; deleting a collection item removes it from all setups
+- No unique constraint on (setupId, itemId) at DB level -- enforce in service layer for better error messages
+- `addedAt` for potential future ordering, but not critical for v1
+
+### Pattern 2: Batch Sync for Setup Items
+**What:** Instead of individual add/remove endpoints, use a single "sync" endpoint that receives the full list of selected item IDs
+**When to use:** When the checklist picker submits all selections at once via "Done" button
+
+```typescript
+// In setup.service.ts
+export function syncSetupItems(db: Db = prodDb, setupId: number, itemIds: number[]) {
+  return db.transaction((tx) => {
+    // Delete all existing setup_items for this setup
+    tx.delete(setupItems).where(eq(setupItems.setupId, setupId)).run();
+    // Insert new ones
+    if (itemIds.length > 0) {
+      tx.insert(setupItems)
+        .values(itemIds.map(itemId => ({ setupId, itemId })))
+        .run();
+    }
+  });
+}
+```
+
+**Why batch sync over individual add/remove:**
+- The checklist picker has a "Done" button that submits all at once
+- Simpler than tracking individual toggles
+- Single transaction = atomic operation
+- Still need a single-item remove for the x button on cards (separate endpoint)
+
+### Pattern 3: Setup Totals via SQL Aggregation
+**What:** Compute setup weight/cost totals server-side by joining `setup_items` with `items`
+**When to use:** For the setup detail page totals bar and setup list cards
+
+```typescript
+// In setup.service.ts
+export function getSetupWithItems(db: Db = prodDb, setupId: number) {
+  const setup = db.select().from(setups).where(eq(setups.id, setupId)).get();
+  if (!setup) return null;
+
+  const itemList = db
+    .select({
+      id: items.id,
+      name: items.name,
+      weightGrams: items.weightGrams,
+      priceCents: items.priceCents,
+      categoryId: items.categoryId,
+      notes: items.notes,
+      productUrl: items.productUrl,
+      imageFilename: items.imageFilename,
+      createdAt: items.createdAt,
+      updatedAt: items.updatedAt,
+      categoryName: categories.name,
+      categoryEmoji: categories.emoji,
+    })
+    .from(setupItems)
+    .innerJoin(items, eq(setupItems.itemId, items.id))
+    .innerJoin(categories, eq(items.categoryId, categories.id))
+    .where(eq(setupItems.setupId, setupId))
+    .all();
+
+  return { ...setup, items: itemList };
+}
+```
+
+**Totals are computed client-side from the items array** (not a separate endpoint) since the setup detail page already fetches all items. This avoids an extra API call and keeps totals always in sync with displayed data.
+
+For the setup list cards (showing totals per setup), use a SQL subquery:
+
+```typescript
+export function getAllSetups(db: Db = prodDb) {
+  return db
+    .select({
+      id: setups.id,
+      name: setups.name,
+      createdAt: setups.createdAt,
+      updatedAt: setups.updatedAt,
+      itemCount: sql<number>`(
+        SELECT COUNT(*) FROM setup_items
+        WHERE setup_items.setup_id = setups.id
+      )`.as("item_count"),
+      totalWeight: sql<number>`COALESCE((
+        SELECT SUM(items.weight_grams) FROM setup_items
+        INNER JOIN items ON setup_items.item_id = items.id
+        WHERE setup_items.setup_id = setups.id
+      ), 0)`.as("total_weight"),
+      totalCost: sql<number>`COALESCE((
+        SELECT SUM(items.price_cents) FROM setup_items
+        INNER JOIN items ON setup_items.item_id = items.id
+        WHERE setup_items.setup_id = setups.id
+      ), 0)`.as("total_cost"),
+    })
+    .from(setups)
+    .orderBy(desc(setups.updatedAt))
+    .all();
+}
+```
+
+### Pattern 4: Route-Aware TotalsBar
+**What:** Make TotalsBar show different content based on the current route
+**When to use:** Dashboard shows "GearBox" title only; collection shows global totals; setup detail shows setup-specific totals
+
+```typescript
+// TotalsBar accepts optional props to override default behavior
+interface TotalsBarProps {
+  title?: string;          // Override the title text
+  stats?: TotalsStat[];    // Override stats display (empty = title only)
+  linkTo?: string;         // Make title a link (defaults to "/")
+}
+```
+
+**Approach:** Rather than making TotalsBar read route state internally, have each page pass the appropriate stats. This keeps TotalsBar a pure presentational component.
+
+- Dashboard page: `<TotalsBar />` (title only, no stats, no link since already on dashboard)
+- Collection page: `<TotalsBar stats={globalStats} />` (current behavior)
+- Setup detail: `<TotalsBar title={setupName} stats={setupStats} />`
+- Thread detail: keep current behavior
+
+The "GearBox" title becomes a `<Link to="/">` on all pages except the dashboard itself.
+
+### Pattern 5: TanStack Router File-Based Routing
+**What:** New route files auto-register via TanStack Router plugin
+**When to use:** Creating `/collection`, `/setups`, `/setups/:id` routes
+
+```
+src/client/routes/
+  __root.tsx                    # Existing root layout
+  index.tsx                     # REWRITE: Dashboard
+  collection/
+    index.tsx                   # NEW: current index.tsx content moves here
+  setups/
+    index.tsx                   # NEW: setups list
+    $setupId.tsx                # NEW: setup detail
+  threads/
+    $threadId.tsx               # Existing, unchanged
+```
+
+The TanStack Router plugin will auto-generate `routeTree.gen.ts` with the new routes. Route files use `createFileRoute("/path")` -- the path must match the file location.
+
+### Pattern 6: Dashboard Summary Stats
+**What:** Dashboard cards need aggregate data from multiple domains
+**When to use:** The dashboard page
+
+The dashboard needs: collection item count + total weight + total cost, active thread count, setup count. Two approaches:
+
+**Recommended: Aggregate on client from existing hooks**
+- `useTotals()` already provides collection stats
+- `useThreads()` provides thread list (count from `.length`)
+- New `useSetups()` provides setup list (count from `.length`)
+
+This avoids a new dashboard-specific API endpoint. Three parallel queries that TanStack Query handles efficiently with its deduplication.
+
+### Anti-Patterns to Avoid
+- **Don't add setup state to Zustand beyond UI concerns:** Setup data belongs in TanStack Query cache, not Zustand. Zustand is only for panel open/close state.
+- **Don't compute totals in the component loop:** Use SQL aggregation for list views, and derive from the fetched items array for detail views.
+- **Don't create a separate "dashboard totals" API:** Reuse existing totals endpoint + new setup/thread counts from their list endpoints.
+
+## Don't Hand-Roll
+
+| Problem | Don't Build | Use Instead | Why |
+|---------|-------------|-------------|-----|
+| Many-to-many sync | Custom diff logic | Delete-all + re-insert in transaction | Simpler, atomic, handles edge cases |
+| Route generation | Manual route registration | TanStack Router file-based plugin | Already configured, auto-generates types |
+| Data fetching cache | Custom cache | TanStack Query | Already used, handles invalidation |
+| SQL totals aggregation | Client-side loops over raw data | SQL COALESCE + SUM subqueries | Consistent with existing totals.service.ts pattern |
+
+**Key insight:** Every pattern in this phase has a direct precedent in Phases 1-2. The only new concept is the junction table.
+
+## Common Pitfalls
+
+### Pitfall 1: Stale Setup Totals After Item Edit
+**What goes wrong:** User edits a collection item's weight/price, but setup detail page shows old totals
+**Why it happens:** Setup query cache not invalidated when items change
+**How to avoid:** In `useUpdateItem` and `useDeleteItem` mutation `onSuccess`, also invalidate `["setups"]` query key
+**Warning signs:** Totals don't update until page refresh
+
+### Pitfall 2: Orphaned Setup Items After Collection Item Deletion
+**What goes wrong:** Deleting a collection item leaves dangling references in `setup_items`
+**Why it happens:** Missing cascade or no FK constraint
+**How to avoid:** `onDelete: "cascade"` on `setupItems.itemId` FK -- already specified in schema pattern above
+**Warning signs:** Setup shows items that no longer exist in collection
+
+### Pitfall 3: Route Migration Breaking Existing Links
+**What goes wrong:** Moving `/` content to `/collection` breaks hardcoded links like the "Back to planning" link in thread detail
+**Why it happens:** Thread detail page currently links to `{ to: "/", search: { tab: "planning" } }`
+**How to avoid:** Update ALL internal links: thread detail back link, resolution dialog redirect, floating add button visibility check
+**Warning signs:** Clicking links after restructure navigates to wrong page
+
+### Pitfall 4: TanStack Router Route Tree Not Regenerating
+**What goes wrong:** New route files exist but routes 404
+**Why it happens:** Vite dev server needs restart, or route file doesn't export `Route` correctly
+**How to avoid:** Use `createFileRoute("/correct/path")` matching the file location. Restart dev server after adding new route directories.
+**Warning signs:** `routeTree.gen.ts` doesn't include new routes
+
+### Pitfall 5: Floating Add Button Showing on Wrong Pages
+**What goes wrong:** The floating "+" button (for adding items) appears on dashboard or setups pages
+**Why it happens:** Current logic only hides it on thread pages (`!threadMatch`)
+**How to avoid:** Update __root.tsx to only show the floating add button on `/collection` route (gear tab)
+**Warning signs:** "+" button visible on dashboard or setup pages
+
+### Pitfall 6: TotalsBar in Root Layout vs Per-Page
+**What goes wrong:** TotalsBar in `__root.tsx` shows global stats on every page including dashboard
+**Why it happens:** TotalsBar is currently rendered unconditionally in root layout
+**How to avoid:** Either (a) make TotalsBar route-aware via props from root, or (b) move TotalsBar out of root layout and render per-page. Option (a) is simpler -- pass a mode/props based on route matching.
+**Warning signs:** Dashboard shows stats in TotalsBar instead of just the title
+
+## Code Examples
+
+### Setup Zod Schemas
+```typescript
+// In src/shared/schemas.ts
+export const createSetupSchema = z.object({
+  name: z.string().min(1, "Setup name is required"),
+});
+
+export const updateSetupSchema = z.object({
+  name: z.string().min(1).optional(),
+});
+
+export const syncSetupItemsSchema = z.object({
+  itemIds: z.array(z.number().int().positive()),
+});
+```
+
+### Setup Hooks Pattern
+```typescript
+// In src/client/hooks/useSetups.ts -- follows useThreads.ts pattern exactly
+export function useSetups() {
+  return useQuery({
+    queryKey: ["setups"],
+    queryFn: () => apiGet<SetupListItem[]>("/api/setups"),
+  });
+}
+
+export function useSetup(setupId: number | null) {
+  return useQuery({
+    queryKey: ["setups", setupId],
+    queryFn: () => apiGet<SetupWithItems>(`/api/setups/${setupId}`),
+    enabled: setupId != null,
+  });
+}
+
+export function useSyncSetupItems(setupId: number) {
+  const queryClient = useQueryClient();
+  return useMutation({
+    mutationFn: (itemIds: number[]) =>
+      apiPut<{ success: boolean }>(`/api/setups/${setupId}/items`, { itemIds }),
+    onSuccess: () => {
+      queryClient.invalidateQueries({ queryKey: ["setups"] });
+    },
+  });
+}
+```
+
+### Remove Single Item from Setup
+```typescript
+// Separate from batch sync -- used by the x button on item cards in setup detail
+export function useRemoveSetupItem(setupId: number) {
+  const queryClient = useQueryClient();
+  return useMutation({
+    mutationFn: (itemId: number) =>
+      apiDelete<{ success: boolean }>(`/api/setups/${setupId}/items/${itemId}`),
+    onSuccess: () => {
+      queryClient.invalidateQueries({ queryKey: ["setups"] });
+    },
+  });
+}
+```
+
+### Dashboard Route
+```typescript
+// src/client/routes/index.tsx -- new dashboard
+import { createFileRoute, Link } from "@tanstack/react-router";
+
+export const Route = createFileRoute("/")({
+  component: DashboardPage,
+});
+
+function DashboardPage() {
+  // Three hooks in parallel -- TanStack Query deduplicates
+  const { data: totals } = useTotals();
+  const { data: threads } = useThreads();
+  const { data: setups } = useSetups();
+
+  const activeThreadCount = threads?.filter(t => t.status === "active").length ?? 0;
+
+  return (
+    <div className="max-w-7xl mx-auto px-4 sm:px-6 lg:px-8 py-6">
+      <div className="grid grid-cols-1 md:grid-cols-3 gap-6">
+        <DashboardCard to="/collection" ... />
+        <DashboardCard to="/collection?tab=planning" ... />
+        <DashboardCard to="/setups" ... />
+      </div>
+    </div>
+  );
+}
+```
+
+### Collection Route (moved from current index.tsx)
+```typescript
+// src/client/routes/collection/index.tsx
+import { createFileRoute } from "@tanstack/react-router";
+import { z } from "zod";
+
+const searchSchema = z.object({
+  tab: z.enum(["gear", "planning"]).catch("gear"),
+});
+
+export const Route = createFileRoute("/collection/")({
+  validateSearch: searchSchema,
+  component: CollectionPage,
+});
+
+function CollectionPage() {
+  // Exact same content as current HomePage in src/client/routes/index.tsx
+  // Just update navigation targets (e.g., handleTabChange navigates to "/collection")
+}
+```
+
+## State of the Art
+
+| Old Approach | Current Approach | When Changed | Impact |
+|--------------|------------------|--------------|--------|
+| Current `/` has gear+planning | `/` becomes dashboard, content moves to `/collection` | Phase 3 | All internal links must update |
+| TotalsBar always shows global stats | TotalsBar becomes route-aware with contextual stats | Phase 3 | Root layout needs route matching logic |
+| No many-to-many relationships | `setup_items` junction table | Phase 3 | New Drizzle pattern for this project |
+
+## Open Questions
+
+1. **Should setup deletion require confirmation?**
+   - What we know: CONTEXT.md mentions using ConfirmDialog for setup deletion
+   - What's unclear: Whether to also confirm when removing all items from a setup
+   - Recommendation: Use ConfirmDialog for setup deletion (destructive). No confirmation for removing individual items from setup (non-destructive, per CONTEXT.md decision).
+
+2. **Should `useThreads` on dashboard include resolved threads for the count?**
+   - What we know: Dashboard "Planning" card shows active thread count
+   - What's unclear: Whether to show "3 active" or "3 active / 5 total"
+   - Recommendation: Show only active count for simplicity. `useThreads(false)` already filters to active.

+### Requirements Coverage
+
+| Requirement | Source Plan | Description | Status | Evidence |
+|-------------|-------------|-------------|--------|----------|
+| SETP-01 | 03-01, 03-02 | User can create named setups | SATISFIED | `createSetup` service + `POST /api/setups` + setups list page with inline create form |
+| SETP-02 | 03-01, 03-02 | User can add/remove collection items to a setup | SATISFIED | `syncSetupItems` + `removeSetupItem` + `ItemPicker` + `ItemCard.onRemove` |
+| SETP-03 | 03-01, 03-02 | User can see total weight and cost for a setup | SATISFIED | SQL aggregation in `getAllSetups`; client-side totals in `$setupId.tsx` sticky bar |
+| DASH-01 | 03-02 | User sees dashboard home page with cards linking to collection, threads, and setups | SATISFIED | `routes/index.tsx` renders three `DashboardCard` components; all three cards link to correct routes |
+
+No orphaned requirements — all four IDs declared in the plans map to Phase 3 in REQUIREMENTS.md, and all four appear in at least one plan's `requirements` field.
+
+---
+
+### Anti-Patterns Found
+
+No blockers or warnings found. Scanned all 14 files modified in Phase 3.
+
+| File | Pattern Checked | Result |
+|------|-----------------|--------|
+| `src/server/services/setup.service.ts` | Empty returns, TODO comments | Clean |
+| `src/server/routes/setups.ts` | Static mock returns, unimplemented stubs | Clean |
+| `src/client/routes/index.tsx` | Placeholder returns, hardcoded zeros | Clean — uses live query data |
+| `src/client/routes/setups/$setupId.tsx` | Orphaned state, non-functional buttons | Clean |
+| `src/client/components/ItemPicker.tsx` | Done button no-op | Clean — calls `syncItems.mutate` |
+| `src/client/components/TotalsBar.tsx` | Stats always empty | Clean — backward-compatible default |
+| `src/client/hooks/useSetups.ts` | Missing invalidations | Clean — all mutations invalidate `["setups"]` |
+| `src/client/hooks/useItems.ts` | Missing cross-invalidation | Clean — `useUpdateItem` and `useDeleteItem` both invalidate `["setups"]` |
+
+---
+
+### TypeScript Compilation Notes
+
+`npx tsc --noEmit` reports errors, but inspection confirms they are all pre-existing issues unrelated to Phase 3:
+
+- `src/client/components/CategoryPicker.tsx` and `OnboardingWizard.tsx` — pre-existing errors from Phase 1/2
+- `tests/routes/*.test.ts` and `tests/services/*.test.ts` — `c.set("db", ...)` type errors present across all test files including Phase 1/2 files; these do not prevent tests from running (all 87 tests pass)
+
+The Plan 02 SUMMARY confirms these were pre-existing: "TypeScript compiles clean (only pre-existing warnings in CategoryPicker/OnboardingWizard)".
+
+---
+
+### Human Verification Required
+
+The following behaviors require a running browser to confirm, as they cannot be verified by static code analysis:
+
+#### 1. Dashboard card navigation
+
+**Test:** Visit http://localhost:5173/, click each of the three cards.
+**Expected:** Collection card navigates to /collection, Planning card navigates to /collection?tab=planning, Setups card navigates to /setups.
+**Why human:** Link targets are present in code but click behavior and router resolution need runtime confirmation.
+
+#### 2. GearBox title back-link from sub-pages
+
+**Test:** Navigate to /collection, /setups, and a setup detail page. Click the "GearBox" title in the top bar.
+**Expected:** Returns to / (dashboard) from all three pages.
+**Why human:** `linkTo="/"` is passed in code, but hover state and click behavior require visual confirmation.
+
+#### 3. FAB only appears on /collection gear tab
+
+**Test:** Visit /, /collection (gear tab), /collection?tab=planning, /setups, and a setup detail page.
+**Expected:** The floating + button appears only on /collection with the gear tab active.
+**Why human:** Conditional `showFab` logic is present but interaction with tab state requires runtime verification.
+
+#### 4. Item picker category grouping and sync
+
+**Test:** Open a setup detail page, click "Add Items", check multiple items across categories, click "Done".
+**Expected:** SlideOutPanel shows items grouped by category emoji; selected items appear on the detail page; totals update.
+**Why human:** The checklist rendering, group headers, and optimistic/refetch behavior require visual inspection.
+
+#### 5. Setup totals update reactively
+
+**Test:** On a setup detail page, remove an item using the x button, then add it back via the picker.
+**Expected:** Item count, weight, and cost in the sticky bar update immediately after each action.
+**Why human:** Client-side totals recompute from the query cache on refetch; timing requires observation.
+
+---
+
+### Gaps Summary
+
+No gaps. All automated checks passed:
+
+- All 10 observable truths verified against actual code
+- All 15 artifacts exist, are substantive (not stubs), and are wired
+- All 7 key links confirmed present and functional
+- All 4 requirements (SETP-01, SETP-02, SETP-03, DASH-01) fully covered
+- 87 backend tests pass (24 from this phase)
+- No anti-patterns found in Phase 3 files
+- 5 human verification items identified for browser confirmation (visual/interactive behaviors only)

+
+For current requirements, see `.planning/REQUIREMENTS.md`.
+
+---
+
+# Requirements: GearBox
+
+**Defined:** 2026-03-15
+**Core Value:** Make it effortless to manage gear and plan new purchases -- see how a potential buy affects your total setup weight and cost before committing.
+
+## v1.1 Requirements
+
+Requirements for v1.1 Fixes & Polish. Each maps to roadmap phases.
+
+### Database
+
+- [x] **DB-01**: Threads table exists in database (schema push creates all missing tables)
+
+### Images
+
+- [x] **IMG-01**: User can see uploaded images displayed on item detail views
+- [x] **IMG-02**: User can see item images on gear collection cards
+- [x] **IMG-03**: User sees image preview area at top of item form with placeholder icon when no image is set
+- [x] **IMG-04**: User can upload an image by clicking the placeholder area
+
+### Planning
+
+- [x] **PLAN-01**: User can create a new planning thread without errors
+- [x] **PLAN-02**: User sees a polished empty state when no threads exist (clear CTA to create first thread)
+
+### Categories
+
+- [x] **CAT-01**: User can select a Lucide icon when creating/editing a category (icon picker)
+- [x] **CAT-02**: Category icons display as Lucide icons throughout the app (cards, headers, lists)
+- [x] **CAT-03**: Existing emoji categories are migrated to equivalent Lucide icons
+
+## Future Requirements
+
+Deferred from v1.0 Active list. Not in current roadmap.
+
+### Search & Filtering
+
+- **SRCH-01**: User can search items by name and filter by category
+
+### Thread Enhancements
+
+- **THRD-01**: User can compare candidates side-by-side on weight and price
+- **THRD-02**: User can track candidate status (researching -> ordered -> arrived)
+- **THRD-03**: User can rank/prioritize candidates within threads
+- **THRD-04**: User can preview how a candidate affects setup weight/cost
+
+### Data Management
+
+- **DATA-01**: User can select weight units (g, oz, lb, kg)
+- **DATA-02**: User can import/export gear collections via CSV
+
+### Visualization
+
+- **VIZ-01**: User can see weight distribution chart by category
+
+### Setup Enhancements
+
+- **SETUP-01**: User can classify items as base weight, worn, or consumable per setup
+
+## Out of Scope
+
+| Feature | Reason |
+|---------|--------|
+| PostgreSQL migration | SQLite sufficient for single-user app |
+| Authentication / multi-user | Single user, no login needed |
+| Custom comparison parameters | Complexity trap, weight/price covers 80% |
+| Mobile native app | Web-first, responsive design sufficient |
+| Social/sharing features | Different product |
+| Price tracking / deal alerts | Requires scraping, fragile |
+
+## Traceability
+
+Which phases cover which requirements. Updated during roadmap creation.

+<objective>
+Fix the missing threads table in the database and add categoryId to threads so thread creation works end-to-end.
+
+Purpose: DB-01 (threads table exists) and the backend half of PLAN-01 (thread creation works with category). Without this, the planning tab crashes on any thread operation.
+Output: Working database schema, updated API that accepts categoryId on thread creation, and thread list returns category info.

+  <files>src/db/schema.ts, src/shared/schemas.ts, src/shared/types.ts, tests/helpers/db.ts</files>
+  <action>
+1. In `src/db/schema.ts`, add `categoryId` column to the `threads` table:

+   categoryId: integer("category_id").notNull().references(() => categories.id),
+   ```
+   Place it after the `resolvedCandidateId` field.

+1. **Task 1: Add categoryId to threads schema, Zod schemas, types, and test helper** - `629e14f` (feat)
+2. **Task 2: Update thread service and routes to handle categoryId, update hook types** - `ed85081` (feat)
+
+## Files Created/Modified
+- `src/db/schema.ts` - Added categoryId column with FK to categories on threads table
+- `src/shared/schemas.ts` - createThreadSchema requires categoryId, updateThreadSchema accepts optional categoryId
+- `src/shared/types.ts` - Types auto-inferred from updated Zod schemas (no manual changes needed)
+- `src/server/services/thread.service.ts` - createThread inserts categoryId, getAllThreads joins categories, updateThread accepts categoryId
+- `src/client/hooks/useThreads.ts` - ThreadListItem includes categoryId/categoryName/categoryEmoji, useCreateThread sends categoryId
+- `tests/helpers/db.ts` - Test DB CREATE TABLE for threads includes category_id column
+- `tests/services/thread.service.test.ts` - All createThread calls include categoryId: 1
+- `tests/routes/threads.test.ts` - createThreadViaAPI and inline POST include categoryId: 1
+
+## Decisions Made
+- categoryId on threads is NOT NULL with FK to categories -- every thread must belong to a category, consistent with how items work
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] Fixed test files to pass categoryId when creating threads**
+- **Found during:** Task 2 (service and route updates)
+- **Issue:** All thread tests called createThread/createThreadViaAPI with only { name } but categoryId is now required, causing 24 test failures
+- **Fix:** Added categoryId: 1 (seeded Uncategorized category) to all createThread calls in service and route tests
+- **Files modified:** tests/services/thread.service.test.ts, tests/routes/threads.test.ts
+- **Verification:** All 87 tests pass
+- **Committed in:** ed85081 (Task 2 commit)
+
+---
+
+**Total deviations:** 1 auto-fixed (1 bug)
+**Impact on plan:** Necessary fix for test correctness after schema change. No scope creep.
+
+## Issues Encountered
+None
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
+- Thread creation with categoryId works end-to-end via API
+- Planning tab frontend (04-02) can now create threads with category and display category info in thread lists
+- Database schema is stable for thread operations

+<objective>
+Build the frontend for thread creation modal, polished empty state, Active/Resolved pill tabs, category filter, and category display on thread cards.
+
+Purpose: PLAN-01 (user can create threads without errors via modal) and PLAN-02 (polished empty state with CTA). This completes the planning tab UX overhaul.
+Output: Working planning tab with modal-based thread creation, educational empty state, pill tab filtering, and category-aware thread cards.

+   - Form fields: Thread name (text input, required, min 1 char) and Category (select dropdown populated from `useCategories()` hook).
+   - Category select shows emoji + name for each option. Pre-select the first category.
+   - Submit calls `useCreateThread().mutate({ name, categoryId })`.
+   - On success: close modal (via `closeCreateThreadModal` from uiStore), reset form.
+   - On error: show inline error message.
+   - Cancel button and clicking backdrop closes modal.
+   - Disable submit button while `isPending`.

+  <action>
+1. In `src/client/components/ThreadCard.tsx`:
+   - Add `categoryName: string` and `categoryEmoji: string` props to `ThreadCardProps`.
+   - Display category as a pill badge (emoji + name) in the card's badge row, using a style like `bg-blue-50 text-blue-700` to distinguish from existing badges.
+
+2. In `src/client/routes/collection/index.tsx`, rewrite the `PlanningView` function:
+
+   **Remove:** The inline text input + button form for thread creation. Remove the `showResolved` checkbox.
+
+   **Add state:**
+   - `activeTab: "active" | "resolved"` (default "active") for the pill tab selector.
+   - `categoryFilter: number | null` (default null = all categories) for filtering.
+   - Import `useCategories` hook, `useUIStore`, and `CreateThreadModal`.
+
+   **Layout (top to bottom):**
+
+   a. **Header row:** "Planning Threads" heading on the left, "New Thread" button on the right. Button calls `openCreateThreadModal()` from uiStore. Use a plus icon (inline SVG, same pattern as collection empty state button).
+
+   b. **Filter row:** Active/Resolved pill tab selector on the left, category filter dropdown on the right.
+      - Pill tabs: Two buttons styled as a segment control. Active pill gets `bg-blue-600 text-white`, inactive gets `bg-gray-100 text-gray-600 hover:bg-gray-200`. Rounded-full, px-4 py-1.5, text-sm font-medium. Wrap in a `flex bg-gray-100 rounded-full p-0.5 gap-0.5` container.
+      - Category filter: A `<select>` dropdown with "All categories" as default option, then each category with emoji + name. Filter threads client-side by matching `thread.categoryId === categoryFilter`.
+
+   c. **Thread list or empty state:**
+      - Pass `activeTab === "resolved"` as `includeResolved` to `useThreads`. When `activeTab === "active"`, show only active threads. When `activeTab === "resolved"`, filter the results to show only resolved threads (since `includeResolved=true` returns both).
+      - Apply `categoryFilter` on the client side if set.
+
+   d. **Empty state (when filtered threads array is empty AND activeTab is "active" AND no category filter):**
+      - Guided + educational tone per user decision.
+      - Max-width container (max-w-lg mx-auto), centered, py-16.
+      - Heading: "Plan your next purchase" (text-xl font-semibold).
+      - Three illustrated steps showing the workflow, each as a row with a step number circle (1, 2, 3), a short title, and a description:
+        1. "Create a thread" -- "Start a research thread for gear you're considering"
+        2. "Add candidates" -- "Add products you're comparing with prices and weights"
+        3. "Pick a winner" -- "Resolve the thread and the winner joins your collection"
+      - Style each step: flex row, step number in a 8x8 rounded-full bg-blue-100 text-blue-700 font-bold circle, title in font-medium, description in text-sm text-gray-500.
+      - CTA button below steps: "Create your first thread" -- calls `openCreateThreadModal()`. Blue-600 bg, white text, same style as collection empty state button.
+      - If empty because of active filter (category or "resolved" tab), show a simpler "No threads found" message instead of the full educational empty state.
+
+   e. **Render `<CreateThreadModal />` at the bottom** of PlanningView (it reads its own open/close state from uiStore).
+
+   f. **Thread grid:** Keep existing `grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3 gap-4`. Pass `categoryName` and `categoryEmoji` as new props to ThreadCard.

+# Phase 4: Database & Planning Fixes - Context
+
+**Gathered:** 2026-03-15
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+Fix the missing threads/thread_candidates tables in the database, fix thread creation errors, and polish the planning tab UX including empty state, thread creation flow, and list layout. No new thread features (status tracking, comparison, etc.) — those are future phases.
+
+</domain>
+
+<decisions>
+## Implementation Decisions
+
+### Empty state design
+- Guided + educational tone — explain what threads are for, not just "nothing here"
+- Illustrated steps showing the flow: Create thread → Add candidates → Pick winner
+- CTA button opens a modal dialog (not inline form)
+- Should feel inviting and help new users understand the planning workflow
+
+### Thread creation flow
+- Always use a modal dialog for thread creation (both empty state and when threads exist)
+- Modal collects: thread name (required) + category (required)
+- Add `categoryId` column to threads table schema (foreign key to categories)
+- Candidates created in a thread auto-inherit the thread's category by default (can be overridden per candidate)
+- Remove the current inline text input + button form
+
+### Planning tab layout
+- Thread cards show category (icon + name) alongside existing info (candidate count, price range, date)
+- Category filter — let users filter thread list by category
+- Replace "Show archived threads" checkbox with Active / Resolved pill tab selector
+- Threads sorted newest first by default
+
+### Claude's Discretion
+- "Create thread" button placement when threads exist (header area vs floating)
+- Validation UX for thread creation modal (empty name handling, duplicate warnings)
+- Loading skeleton design
+- Exact spacing and typography
+- Category filter UI pattern (dropdown, pills, sidebar)
+
+</decisions>
+
+<code_context>
+## Existing Code Insights
+
+### Reusable Assets
+- `ThreadCard` component (`src/client/components/ThreadCard.tsx`): Existing card with name, candidate count, price range, date, status badge — needs category addition
+- `CategoryHeader` component: Shows category emoji + name + totals — pattern for category display
+- `useThreads` / `useCreateThread` hooks: Existing data fetching and mutation hooks
+- `useUIStore` (Zustand): Panel/dialog state management — use for create thread modal
+- Collection empty state (`src/client/routes/collection/index.tsx` lines 59-93): Pattern for empty states with emoji, heading, description, CTA button
+
+### Established Patterns
+- Drizzle ORM schema in `src/db/schema.ts` — add categoryId column to threads table here
+- `@hono/zod-validator` for request validation on server routes
+- Service layer with db as first param for testability
+- TanStack Query for data fetching with query invalidation on mutations
+- Tab navigation via URL search params (gear/planning tabs)
+
+### Integration Points
+- `src/db/schema.ts`: Add categoryId to threads table
+- `src/server/routes/threads.ts`: Update create/update endpoints for categoryId
+- `src/server/services/thread.service.ts`: Update service functions
+- `src/shared/schemas.ts`: Update Zod schemas for thread creation
+- `src/client/routes/collection/index.tsx` PlanningView: Replace inline form with modal trigger, add empty state, add pill tabs, add category filter
+- `src/client/components/ThreadCard.tsx`: Add category display
+- `tests/helpers/db.ts`: Update CREATE TABLE for threads to include category_id
+
+</code_context>
+
+<specifics>
+## Specific Ideas
+
+- The empty state illustrated steps should visually show the 3-step planning workflow (Create thread → Add candidates → Pick winner) — make it clear what threads are for
+- Pill tabs for Active/Resolved should feel like a segment control, not full page tabs
+- Category on thread cards should use the same icon + name pattern used elsewhere in the app
+
+</specifics>
+
+<deferred>
+## Deferred Ideas
+
+None — discussion stayed within phase scope

+|-------------|-------------|------------------------------------------------------------------|-----------|---------------------------------------------------------------------------------------|
+| DB-01       | 04-01       | Threads table exists in database                                 | SATISFIED | `schema.ts` defines threads table; test helper mirrors it; 87 tests pass with it     |
+| PLAN-01     | 04-01, 04-02| User can create a new planning thread without errors             | SATISFIED | Full stack verified: Zod schema → route → service (categoryId insert) → modal UI     |
+| PLAN-02     | 04-02       | User sees a polished empty state when no threads exist           | SATISFIED | `collection/index.tsx` renders 3-step educational empty state with CTA when no threads |
+
+All three requirements declared across both plan frontmatters are accounted for. No orphaned requirements — REQUIREMENTS.md traceability table maps DB-01, PLAN-01, PLAN-02 exclusively to Phase 4 (marked Complete).
+
+### Anti-Patterns Found
+
+| File | Line | Pattern | Severity | Impact |
+|------|------|---------|----------|--------|
+| (none) | — | — | — | No stubs, placeholders, empty implementations, or TODO comments found in phase-modified files |
+
+Lint check: `bun run lint` reports 144 errors across the project, but zero errors in any of the 8 files modified by this phase. All pre-existing lint errors are in files unrelated to phase 4.
+
+### Human Verification Required
+
+The following items cannot be verified programmatically and need browser testing to confirm full goal achievement:
+
+#### 1. Modal opens and thread creation completes end-to-end
+
+**Test:** Visit `/collection?tab=planning`, click "Create your first thread" CTA, fill name and category, submit.
+**Expected:** Thread appears in the grid as a card with category badge (emoji + name). No console errors.
+**Why human:** Cannot verify runtime React Query mutation success, modal close behavior, or actual API roundtrip in browser without running the stack.
+
+#### 2. Pill tab Active/Resolved filtering works at runtime
+
+**Test:** With both active and resolved threads present, toggle between Active and Resolved pills.
+**Expected:** Each tab shows only threads of the matching status.
+**Why human:** Client-side filter logic (`t.status === activeTab`) is correct in code but runtime behavior depends on API returning correct `status` field values.
+
+#### 3. Category filter narrows thread list
+
+**Test:** With threads in multiple categories, select a specific category from the dropdown.
+**Expected:** Only threads matching that category remain visible.
+**Why human:** Runtime verification of `t.categoryId === categoryFilter` filtering in the browser.
+
+### Gaps Summary
+
+None. All must-haves are verified. All requirement IDs (DB-01, PLAN-01, PLAN-02) are satisfied with evidence in the codebase. The phase goal — users can create and manage planning threads without errors — is achieved:
+
+- The threads table schema is correct and tested (87 tests pass)
+- The API accepts and persists `categoryId` on thread creation
+- The modal UI sends `{ name, categoryId }` to the mutation
+- Category info is returned from the API and displayed on thread cards
+- An educational empty state guides first-time users
+- Active/Resolved pill tabs replace the old checkbox
+
+Three items are flagged for human browser verification, but all automated checks pass with no gaps.

+<objective>
+Fix the image display bug so uploaded images render correctly, then redesign the ImageUpload component into a hero image preview area and move it to the top of both ItemForm and CandidateForm.
+
+Purpose: Images upload but don't display -- fixing this is the prerequisite for all image UX. The hero area redesign makes images prominent and the upload interaction intuitive (click placeholder to add, click image to replace).
+
+Output: Working image display, redesigned ImageUpload component, updated ItemForm and CandidateForm.

+  <action>
+Investigate why uploaded images don't render in the UI. The upload flow works (apiUpload POSTs to /api/images, server saves to ./uploads/ with UUID filename, returns { filename }), but images don't display.
+
+Debugging checklist (work through systematically):
+1. Start dev servers (`bun run dev:server` and `bun run dev:client`) and upload a test image
+2. Check the uploads/ directory -- does the file exist on disk?
+3. Try accessing the image directly via browser: `http://localhost:5173/uploads/{filename}` -- does it load?
+4. If not, try `http://localhost:3000/uploads/{filename}` -- does the backend serve it?
+5. Check Vite proxy config in vite.config.ts -- `/uploads` proxy to `http://localhost:3000` is configured
+6. Check Hono static serving in src/server/index.ts -- `serveStatic({ root: "./" })` should serve `./uploads/*`
+7. Check if the `imageFilename` field is actually being saved to the database and returned by GET /api/items
+
+Common suspects:
+- The serveStatic middleware path might not match (root vs rewrite issue)
+- The imageFilename might not be persisted in the database (check the item update/create service)
+- The Vite proxy might need a rewrite rule
+
+Fix the root cause. If the issue is in static file serving, fix the serveStatic config. If it's a database persistence issue, fix the service layer. If it's a proxy issue, fix vite.config.ts.
+
+After fixing, verify an uploaded image displays at `/uploads/{filename}` in the browser.

+Redesign ImageUpload.tsx into a hero image preview area per user decisions:
+
+**ImageUpload component redesign:**
+- Full-width container with `aspect-[4/3]` ratio (matches ItemCard)
+- Rounded corners (`rounded-xl`), overflow-hidden
+- The entire area is clickable (triggers hidden file input)
+
+**When no image (placeholder state):**
+- Light gray background (bg-gray-50 or bg-gray-100)
+- Centered Lucide `ImagePlus` icon (install lucide-react if not present, or use inline SVG) in gray-300/gray-400
+- "Click to add photo" text below the icon in text-sm text-gray-400
+- Cursor pointer on hover
+
+**When image exists (preview state):**
+- Full-width image with `object-cover` filling the 4:3 area
+- Small circular X button in top-right corner: `absolute top-2 right-2`, white/semi-transparent bg, rounded-full, ~28px, with X icon. onClick calls onChange(null) and stops propagation (so it doesn't trigger file picker)
+- Clicking the image itself opens file picker to replace
+
+**When uploading:**
+- Spinner overlay centered on the hero area (simple CSS spinner or Loader2 icon from lucide-react with animate-spin)
+- Semi-transparent overlay (bg-white/60 or bg-black/20) over the placeholder/current image
+
+**Error state:**
+- Red text below the hero area (same as current)
+
+**Move ImageUpload to top of forms:**
+- In ItemForm.tsx: Move the `<ImageUpload>` from the bottom of the form (currently after Product Link) to the very first element, BEFORE the Name field. Remove the wrapping `<div>` with the "Image" label -- the hero area is self-explanatory.
+- In CandidateForm.tsx: Same change -- move ImageUpload to the top, remove the "Image" label wrapper.
+
+Keep the existing ImageUploadProps interface unchanged ({ value, onChange }) so no other code needs updating.

+# Phase 5 Plan 1: Image Display Fix & Hero Area Summary
+
+**Fixed image persistence bug (Zod schema missing imageFilename) and redesigned ImageUpload as 4:3 hero area at top of item/candidate forms**
+
+## Performance
+
+- **Duration:** 3 min
+- **Started:** 2026-03-15T16:08:51Z
+- **Completed:** 2026-03-15T16:11:27Z
+- **Tasks:** 2
+- **Files modified:** 4
+
+## Accomplishments
+- Identified and fixed root cause of image display bug: imageFilename was missing from Zod validation schemas, causing @hono/zod-validator to silently strip it from payloads
+- Redesigned ImageUpload into a full-width 4:3 hero image area with placeholder, preview, upload spinner, and remove states
+- Moved ImageUpload to first element in both ItemForm and CandidateForm, removing redundant labels
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Fix image display bug and investigate root cause** - `8c0529c` (fix)
+2. **Task 2: Redesign ImageUpload as hero area and move to top of forms** - `3243be4` (feat)
+
+## Files Created/Modified
+- `src/shared/schemas.ts` - Added imageFilename to createItemSchema and createCandidateSchema
+- `src/client/components/ImageUpload.tsx` - Redesigned as 4:3 hero area with placeholder/preview/spinner states
+- `src/client/components/ItemForm.tsx` - Moved ImageUpload to top, removed label wrapper
+- `src/client/components/CandidateForm.tsx` - Moved ImageUpload to top, removed label wrapper
+
+## Decisions Made
+- Used inline SVGs instead of adding lucide-react dependency -- only 3 icons needed, avoids bundle bloat
+- Root cause identified as Zod schema issue, not static file serving or Vite proxy (both were working correctly)
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+None.
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
+- Image display and upload flow fully functional
+- Hero area component ready for any future image-related enhancements in plan 05-02
+- Forms have clean image-first layout

+  <action>
+Update both ItemCard and CandidateCard to ALWAYS render the 4:3 image area (currently they conditionally render it only when imageFilename exists).
+
+**ItemCard.tsx changes:**
+- Replace the conditional `{imageFilename && (...)}` block with an always-rendered `<div className="aspect-[4/3] bg-gray-50">` container
+- When imageFilename exists: render `<img src={/uploads/${imageFilename}} alt={name} className="w-full h-full object-cover" />` (same as current)
+- When imageFilename is null: render a centered placeholder with the category emoji. Use `<div className="w-full h-full flex flex-col items-center justify-center">` containing a `<span className="text-3xl">{categoryEmoji}</span>`. The gray-50 background provides the subtle placeholder look.
+
+**CandidateCard.tsx changes:**
+- Identical treatment: always render the 4:3 area, show image or category emoji placeholder
+- Same structure as ItemCard
+
+Both cards already receive categoryEmoji as a prop, so no prop changes needed.

+  <files>src/client/routes/setups/$setupId.tsx</files>
+  <action>
+The setup detail page currently renders items using ItemCard in a grid. The setup also has a concept of item lists. Add small square thumbnails next to item names in the setup's item display.
+
+Since the setup page uses ItemCard components in a grid (which now have the 4:3 area from Task 1), the card-level display is already handled. The additional work here is for any list-style display of setup items.
+
+Check the setup detail route for list-view rendering of items. If items are only shown via ItemCard grid, then this task focuses on ensuring the ItemCard placeholder works in the setup context. If there's a separate list view, add thumbnails:
+
+**Thumbnail spec (for list views):**
+- Small square image: `w-10 h-10 rounded-lg object-cover flex-shrink-0` (~40px)
+- Placed to the left of the item name in a flex row
+- When imageFilename exists: `<img src={/uploads/${imageFilename}} />`
+- When null: `<div className="w-10 h-10 rounded-lg bg-gray-50 flex items-center justify-center flex-shrink-0"><span className="text-sm">{categoryEmoji}</span></div>`
+
+If the setup page only uses ItemCard (no list view), verify the ItemCard changes from Task 1 render correctly in the setup context and note this in the summary.

+# Phase 5 Plan 2: Image Placeholders & Thumbnails Summary
+
+**Always-visible 4:3 image area on ItemCard and CandidateCard with category emoji placeholders for consistent grid layouts**
+
+## Performance
+
+- **Duration:** 1 min
+- **Started:** 2026-03-15T16:13:39Z
+- **Completed:** 2026-03-15T16:14:40Z
+- **Tasks:** 2
+- **Files modified:** 2
+
+## Accomplishments
+- Replaced conditional image rendering with always-present 4:3 aspect ratio area on both ItemCard and CandidateCard
+- Cards without images now show category emoji centered on gray background, providing visual context
+- Verified setup detail page uses ItemCard grid (no separate list view), so card placeholders serve both contexts
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Add always-visible 4:3 image area with placeholders to ItemCard and CandidateCard** - `acf34c3` (feat)
+2. **Task 2: Add small thumbnails to setup item lists** - No commit needed (setup page only uses ItemCard grid, already updated in Task 1)
+
+## Files Created/Modified
+- `src/client/components/ItemCard.tsx` - Always-visible 4:3 image area with emoji placeholder fallback
+- `src/client/components/CandidateCard.tsx` - Same treatment as ItemCard for consistent behavior
+
+## Decisions Made
+- Setup detail page only uses ItemCard in a grid layout (no separate list view exists), so no additional thumbnail component was needed
+- Category emoji serves as an effective placeholder, providing category context without requiring default images
+
+## Deviations from Plan
+
+None - plan executed exactly as written. The plan anticipated the possibility that the setup page only uses ItemCard grid and specified to verify and note in summary.
+
+## Issues Encountered
+None.
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
+- All image display components complete (upload, hero area, card placeholders)
+- Phase 5 image handling fully complete
+- Ready for Phase 6 category icon system

+# Phase 5: Image Handling - Context
+
+**Gathered:** 2026-03-15
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+Fix image display throughout the app (images upload but don't render), redesign the upload UX with a hero image preview area and placeholder icons, and add image display to gear cards, candidate cards, and setup item lists. No new image features (galleries, editing, tagging) — those would be separate phases.
+
+</domain>
+
+<decisions>
+## Implementation Decisions
+
+### Image preview area (item form)
+- Move image from bottom of form to a full-width hero area at the top
+- 4:3 landscape aspect ratio (matches ItemCard's existing aspect-[4/3])
+- When no image: light gray background with centered Lucide icon (ImagePlus or Camera) and "Click to add photo" text below
+- When image exists: full-width image with object-cover, small circular X button in top-right to remove
+- Clicking the image opens file picker to replace (same behavior as clicking placeholder)
+
+### Card placeholders
+- All cards (items and candidates) show the 4:3 image area always — consistent card heights in grid
+- When no image: light gray (gray-50/gray-100) background with the item's category icon centered
+- Category icons are currently emoji — use whatever is current (Phase 6 will migrate to Lucide)
+- Candidate cards get the same placeholder treatment as item cards
+
+### Upload interaction
+- Click only — no drag-and-drop (keeps it simple for side panel form)
+- Spinner overlay centered on hero area while uploading
+- No client-side image processing (no crop, no resize) — CSS object-cover handles display
+- CandidateForm gets the same hero area redesign as ItemForm
+
+### Image in detail/setup views
+- Clicking uploaded image in form opens file picker to replace (no lightbox/zoom)
+- Setup item lists show small square thumbnails (~40px) with rounded corners next to item name
+- Setup thumbnails show category icon placeholder when item has no image
+
+### Image display bug fix
+- Investigate and fix root cause of images uploading but not rendering (likely path/proxy issue)
+- This is prerequisite work — fix before redesigning the UX
+
+### Claude's Discretion
+- Exact placeholder icon choice (ImagePlus vs Camera vs similar)
+- Spinner animation style
+- Exact gray shade for placeholder backgrounds
+- Transition/animation on image load
+- Error state design for failed uploads
+
+</decisions>
+
+<code_context>
+## Existing Code Insights
+
+### Reusable Assets
+- `ImageUpload` component (`src/client/components/ImageUpload.tsx`): Existing upload logic with file validation, apiUpload call, preview, and remove button — needs restructuring into hero area pattern
+- `ItemCard` (`src/client/components/ItemCard.tsx`): Already renders imageFilename with `aspect-[4/3]` but skips image area when null — needs placeholder addition
+- `CandidateCard` / `CandidateForm`: Candidate equivalents that need same treatment
+- `apiUpload` helper in `lib/api.ts`: Upload function already works
+
+### Established Patterns
+- Images stored as UUID filenames in `./uploads/` directory
+- Server serves `/uploads/*` via `hono/bun` serveStatic
+- Vite dev proxy forwards `/uploads` to `http://localhost:3000`
+- Image upload API at `POST /api/images` returns `{ filename }` (201 status)
+- `imageFilename` field on items and candidates — string or null
+- 5MB max, JPG/PNG/WebP accepted
+
+### Integration Points
+- `src/client/components/ItemForm.tsx`: Move ImageUpload from bottom to top, redesign as hero area
+- `src/client/components/CandidateForm.tsx`: Same hero area redesign
+- `src/client/components/ItemCard.tsx`: Add placeholder when imageFilename is null
+- `src/client/components/CandidateCard.tsx`: Add placeholder when imageFilename is null
+- `src/client/routes/setups/$setupId.tsx`: Add small thumbnails to setup item list
+- Server static file serving: Verify `/uploads/*` path works in both dev and production
+
+</code_context>
+
+<specifics>
+## Specific Ideas
+
+- Hero area should feel like a product photo section — clean, prominent, image-first
+- Placeholder with category icon adds visual meaning even before images are uploaded
+- Consistent 4:3 aspect ratio across hero area and cards keeps everything aligned
+- Setup thumbnails should be compact (40px square) — don't dominate the list layout
+
+</specifics>
+
+<deferred>
+## Deferred Ideas
+
+None — discussion stayed within phase scope

+| 4  | Clicking the placeholder opens file picker and uploaded image replaces placeholder immediately | VERIFIED | `onClick={() => inputRef.current?.click()}` on hero div; `onChange(result.filename)` updates state on success |
+| 5  | When image exists, a small circular X button in top-right removes the image                  | VERIFIED   | `absolute top-2 right-2 w-7 h-7 … rounded-full` button calls `handleRemove` → `onChange(null)` with `stopPropagation` |
+| 6  | Clicking an existing image opens file picker to replace it                                   | VERIFIED   | Entire hero div has `onClick` trigger; `value ? <img …> : <placeholder>` branch — img is inside the clickable div |
+| 7  | CandidateForm has the same hero area redesign as ItemForm                                     | VERIFIED   | `<ImageUpload>` is first element in `CandidateForm` JSX (line 138); identical prop wiring |

+
+## Human Verification Required
+
+### 1. Upload → immediate preview
+
+**Test:** Open ItemForm, click the gray hero area, select a JPEG file.
+**Expected:** Hero area immediately shows the uploaded image (no page reload). The X button appears in the top-right corner.
+**Why human:** Dynamic state update after async upload cannot be verified statically.
+
+### 2. Remove image
+
+**Test:** With an image displayed in the ItemForm hero area, click the X button.
+**Expected:** Hero area reverts to gray placeholder with the ImagePlus icon and "Click to add photo" text. The X button disappears.
+**Why human:** State transition after user interaction.
+
+### 3. Image persists after save
+
+**Test:** Upload an image, fill in a name, click "Add Item". Reopen the item in edit mode.
+**Expected:** The hero area shows the previously uploaded image (not the placeholder). Confirms the Zod schema fix persists imageFilename through the full create-item API round-trip.
+**Why human:** End-to-end persistence across API round-trips.
+
+### 4. Gear collection card consistency
+
+**Test:** View gear collection with a mix of items (some with images, some without).
+**Expected:** All cards are the same height due to the always-present 4:3 area. Cards without images show the category emoji centered on a gray background. No layout shift between card types.
+**Why human:** Visual layout consistency requires visual inspection.
+
+### 5. Setup page image display
+
+**Test:** Open a setup that contains both items with images and items without.
+**Expected:** All ItemCards in the setup grid show consistent heights. Items with images display them; items without show the category emoji placeholder.
+**Why human:** Visual confirmation in the setup context.
+
+---
+
+## Gaps Summary
+
+No gaps. All 13 observable truths verified, all 5 artifacts substantive and wired, all 8 key links confirmed present in code, all 4 requirements satisfied with evidence.
+
+The root cause fix (Zod schema missing `imageFilename`) is verified in `src/shared/schemas.ts` with both `createItemSchema` and `createCandidateSchema` now including the field. The server-side persistence chain is complete: Zod allows the field → service layer writes `imageFilename` to DB → GET returns it → cards render `/uploads/{filename}`.

+<objective>
+Migrate the category data layer from emoji to Lucide icons and create the icon data infrastructure.
+
+Purpose: Establish the foundation (schema, types, icon data, render helper) that all UI components will consume. Without this, no component can display or select Lucide icons.
+Output: Updated DB schema with `icon` column, Zod schemas with `icon` field, all services updated, curated icon data file with render component, Drizzle migration generated, lucide-react installed.

+  <action>
+    1. In `src/db/schema.ts`: Rename the `emoji` column on `categories` to `icon` with `text("icon").notNull().default("package")`. The column name in the database changes from `emoji` to `icon`.
+
+    2. In `src/shared/schemas.ts`:
+       - `createCategorySchema`: Replace `emoji: z.string().min(1).max(4).default("📦")` with `icon: z.string().min(1).max(50).default("package")`. The max is 50 to allow Lucide icon names like "mountain-snow".
+       - `updateCategorySchema`: Replace `emoji: z.string().min(1).max(4).optional()` with `icon: z.string().min(1).max(50).optional()`.
+
+    3. In `src/server/services/category.service.ts`:
+       - `createCategory`: Change function parameter type from `{ name: string; emoji?: string }` to `{ name: string; icon?: string }`. Update the spread to use `data.icon` and `{ icon: data.icon }`.
+       - `updateCategory`: Change parameter type from `{ name?: string; emoji?: string }` to `{ name?: string; icon?: string }`.
+
+    4. In `src/server/services/item.service.ts`: Change `categoryEmoji: categories.emoji` to `categoryIcon: categories.icon` in the select.
+
+    5. In `src/server/services/thread.service.ts`: Same rename — `categoryEmoji: categories.emoji` to `categoryIcon: categories.icon` in both `getAllThreads` and `getThreadById` functions.
+
+    6. In `src/server/services/setup.service.ts`: Same rename — `categoryEmoji` to `categoryIcon`.
+
+    7. In `src/server/services/totals.service.ts`: Same rename — `categoryEmoji` to `categoryIcon`.
+
+    8. In `src/db/seed.ts`: Change `emoji: "\u{1F4E6}"` to `icon: "package"`.
+
+    9. In `tests/helpers/db.ts`: Change the CREATE TABLE statement for categories to use `icon TEXT NOT NULL DEFAULT 'package'` instead of `emoji TEXT NOT NULL DEFAULT '📦'`. Update the seed insert to use `icon: "package"` instead of `emoji: "\u{1F4E6}"`.
+
+    10. Generate the Drizzle migration: Run `bun run db:generate` to create the migration SQL. The migration needs to handle renaming the column AND converting existing emoji values to icon names. After generation, inspect the migration file and add data conversion SQL if Drizzle doesn't handle it automatically. The emoji-to-icon mapping for migration:
+        - 📦 -> "package"
+        - 🏕️/⛺ -> "tent"
+        - 🚲 -> "bike"
+        - 📷 -> "camera"
+        - 🎒 -> "backpack"
+        - 👕 -> "shirt"
+        - 🔧 -> "wrench"
+        - 🍳 -> "cooking-pot"
+        - Any unmapped emoji -> "package" (fallback)
+
+    NOTE: Since SQLite doesn't support ALTER TABLE RENAME COLUMN in all versions, the migration may need to recreate the table. Check the generated migration and ensure it works. If `bun run db:generate` produces a column rename, verify it. If it produces a drop+recreate, ensure data is preserved. You may need to manually write migration SQL that: (a) creates a new column `icon`, (b) updates it from `emoji` with the mapping, (c) drops the `emoji` column. Test with `bun run db:push`.

+  <action>
+    1. Install lucide-react: `bun add lucide-react`
+
+    2. Create `src/client/lib/iconData.ts` with:
+
+    a) An `EMOJI_TO_ICON_MAP` constant (Record&lt;string, string&gt;) mapping emoji characters to Lucide icon names. Cover at minimum:
+       - 📦 -> "package", 🏕️ -> "tent", ⛺ -> "tent", 🚲 -> "bike", 📷 -> "camera"
+       - 🎒 -> "backpack", 👕 -> "shirt", 🔧 -> "wrench", 🍳 -> "cooking-pot"

+       - 🏖️ -> "umbrella-off", 🧭 -> "compass", 🔦 -> "flashlight", 🔋 -> "battery"
+       - 📱 -> "smartphone", 🎧 -> "headphones", 🧤 -> "hand", 🧣 -> "scarf"
+       - 👟 -> "footprints", 🥾 -> "footprints", 🧢 -> "hard-hat", 🕶️ -> "glasses"
+       - Plus any other reasonable gear-related emoji from the old emojiData.ts
+
+    b) An `IconGroup` interface and `iconGroups` array with ~80-120 curated gear-relevant Lucide icons organized into groups:
+       ```typescript
+       interface IconEntry { name: string; keywords: string[] }
+       interface IconGroup { name: string; icon: string; icons: IconEntry[] }
+       ```
+       Groups (matching picker tabs):
+       - **Outdoor**: tent, campfire, mountain, mountain-snow, compass, map, map-pin, binoculars, tree-pine, trees, sun, cloud-rain, snowflake, wind, flame, leaf, flower-2, sunrise, sunset, moon, star, thermometer
+       - **Travel**: backpack, luggage, plane, car, bike, ship, train-front, map-pinned, globe, ticket, route, navigation, milestone, fuel, parking-meter
+       - **Sports**: dumbbell, trophy, medal, timer, heart-pulse, footprints, gauge, target, flag, swords, shield, zap
+       - **Electronics**: laptop, smartphone, tablet-smartphone, headphones, camera, battery, bluetooth, wifi, usb, monitor, keyboard, mouse, gamepad-2, speaker, radio, tv, plug, cable, cpu, hard-drive
+       - **Clothing**: shirt, glasses, watch, gem, scissors, ruler, palette
+       - **Cooking**: cooking-pot, utensils, cup-soda, coffee, beef, fish, apple, wheat, flame-kindling, refrigerator, microwave
+       - **Tools**: wrench, hammer, screwdriver, drill, ruler, tape-measure, flashlight, pocket-knife, axe, shovel, paintbrush, scissors, cog, nut
+       - **General**: package, box, tag, bookmark, archive, folder, grid-3x3, list, layers, circle-dot, square, hexagon, triangle, heart, star, plus, check, x
+
+       Each icon entry has `name` (the Lucide icon name) and `keywords` (array of search terms for filtering).
+
+    c) A `LucideIcon` React component that renders a Lucide icon by name string:
+       ```typescript
+       import { icons } from "lucide-react";
+
+       interface LucideIconProps {
+         name: string;
+         size?: number;
+         className?: string;
+       }
+
+       export function LucideIcon({ name, size = 20, className = "" }: LucideIconProps) {
+         const IconComponent = icons[name as keyof typeof icons];
+         if (!IconComponent) {
+           const FallbackIcon = icons["Package"];
+           return <FallbackIcon size={size} className={className} />;
+         }
+         return <IconComponent size={size} className={className} />;
+       }
+       ```
+
+       IMPORTANT: Lucide icon names in the `icons` map use PascalCase (e.g., "Package", "MountainSnow"). The `name` prop should accept kebab-case (matching Lucide convention) and convert to PascalCase for lookup. Add a conversion helper:
+       ```typescript
+       function toPascalCase(str: string): string {
+         return str.split("-").map(s => s.charAt(0).toUpperCase() + s.slice(1)).join("");
+       }
+       ```
+       Use `icons[toPascalCase(name)]` for lookup.
+
+    NOTE: This approach imports the entire lucide-react icons object for dynamic lookup by name. This is intentional — the icon picker needs access to all icons by name string. Tree-shaking won't help here since we need runtime lookup. The bundle impact is acceptable for this single-user app.

+# Phase 6 Plan 1: Category Icon Data Layer Summary
+
+**Migrated categories from emoji to Lucide icon names with curated 119-icon data set and LucideIcon render component**
+
+## Performance
+
+- **Duration:** 5 min
+- **Started:** 2026-03-15T16:45:02Z
+- **Completed:** 2026-03-15T16:50:15Z
+- **Tasks:** 2
+- **Files modified:** 18
+
+## Accomplishments
+- Renamed emoji column to icon across DB schema, Zod schemas, and all 5 services
+- Created Drizzle migration with emoji-to-icon data conversion for existing categories
+- Built iconData.ts with 119 curated gear-relevant Lucide icons across 8 groups
+- Added LucideIcon component with kebab-to-PascalCase conversion and Package fallback
+- All 87 tests pass, build succeeds
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Migrate schema, Zod schemas, services, test helper, and seed to icon field** - `546dff1` (feat)
+2. **Task 2: Install lucide-react and create icon data file with LucideIcon component** - `fca1eb7` (feat)
+
+## Files Created/Modified
+- `src/db/schema.ts` - Categories table now uses icon column with "package" default
+- `src/shared/schemas.ts` - Zod schemas validate icon as string(1-50)
+- `src/server/services/category.service.ts` - Parameter types use icon instead of emoji
+- `src/server/services/item.service.ts` - Returns categoryIcon instead of categoryEmoji
+- `src/server/services/thread.service.ts` - Returns categoryIcon in both list and detail
+- `src/server/services/setup.service.ts` - Returns categoryIcon in setup item list
+- `src/server/services/totals.service.ts` - Returns categoryIcon in category totals
+- `src/db/seed.ts` - Seeds Uncategorized with icon "package"
+- `tests/helpers/db.ts` - Test helper creates icon column, seeds with "package"
+- `src/client/lib/iconData.ts` - Curated icon groups, LucideIcon component, emoji-to-icon map
+- `drizzle/0001_rename_emoji_to_icon.sql` - Migration SQL with data conversion
+- `package.json` - Added lucide-react dependency
+
+## Decisions Made
+- Used ALTER TABLE RENAME COLUMN for SQLite migration -- simpler than table recreation, supported in SQLite 3.25+
+- Applied migration directly via Bun SQLite API since drizzle-kit push/generate requires interactive input for column renames
+- Included 119 icons (slightly under the upper bound) for comprehensive gear coverage without bloat
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 3 - Blocking] Updated all test files referencing emoji/categoryEmoji**
+- **Found during:** Task 1 (schema migration)
+- **Issue:** Test files referenced emoji field and categoryEmoji property which no longer exist after schema rename
+- **Fix:** Updated 6 test files to use icon/categoryIcon
+- **Files modified:** tests/services/category.service.test.ts, tests/routes/categories.test.ts, tests/services/item.service.test.ts, tests/services/totals.test.ts, tests/services/setup.service.test.ts, tests/services/thread.service.test.ts
+- **Verification:** All 87 tests pass
+- **Committed in:** 546dff1 (Task 1 commit)
+
+---
+
+**Total deviations:** 1 auto-fixed (1 blocking)
+**Impact on plan:** Test updates were necessary for correctness. No scope creep.
+
+## Issues Encountered
+- drizzle-kit generate/push commands require interactive input for column renames -- applied migration SQL directly via Bun SQLite API instead
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
+- Icon data infrastructure complete, ready for UI component work (06-02: IconPicker, 06-03: display integration)
+- Client-side still references categoryEmoji -- will be updated in subsequent plans
+
+## Self-Check: PASSED
+
+All created files verified, all commits found, all key exports confirmed.

+<objective>
+Build the IconPicker component and update all category create/edit components to use Lucide icons instead of emoji.
+
+Purpose: Enable users to browse, search, and select Lucide icons when creating or editing categories. This is the primary user-facing feature of the phase.
+Output: New IconPicker component, updated CategoryPicker, CategoryHeader, OnboardingWizard, and CreateThreadModal.

+    Create `src/client/components/IconPicker.tsx` following the same portal-based popover pattern as EmojiPicker.tsx but rendering Lucide icons.
+
+    Props interface:
+    ```typescript
+    interface IconPickerProps {
+      value: string;           // Current icon name (kebab-case, e.g. "tent")
+      onChange: (icon: string) => void;
+      size?: "sm" | "md";
+    }
+    ```
+
+    Architecture (mirror EmojiPicker exactly for these behaviors):
+    - Portal-based popover via `createPortal(popup, document.body)`
+    - Trigger button: bordered square box showing the selected LucideIcon, or "+" when empty
+    - Position calculation: measure trigger rect, place below (or above if not enough space), clamp left to viewport
+    - Click-outside detection via document mousedown listener
+    - Escape key closes popover
+    - Focus search input on open
+    - `data-icon-picker` attribute on popover div (for click-outside exclusion in CategoryPicker)
+    - Stop mousedown propagation from popover (so parent click-outside handlers don't fire)
+
+    Popover content:
+    - Search input at top (placeholder: "Search icons...")
+    - Group tabs below search (only shown when not searching). Each tab shows a small LucideIcon for that group's `icon` field. Active tab highlighted with blue.
+    - Icon grid: 6 columns. Each cell renders a LucideIcon at 20px, with hover highlight, name as title attribute. On click, call `onChange(icon.name)` and close.
+    - When searching: filter across all groups by matching query against icon `name` and `keywords`. Show flat grid of results. Show "No icons found" if empty.
+    - Popover width: ~w-72 (288px). Max grid height: ~max-h-56 with overflow-y-auto.
+
+    Trigger button styling:
+    - `size="md"`: `w-12 h-12` — icon at 24px inside, gray-500 color
+    - `size="sm"`: `w-10 h-10` — icon at 20px inside, gray-500 color
+    - Border, rounded-md, hover:border-gray-300, hover:bg-gray-50
+
+    Import `iconGroups` and `LucideIcon` from `../lib/iconData`.
+    Import `icons` from `lucide-react` only if needed for tab icons (or just use LucideIcon component for tabs too).

+    - IconPicker component renders a trigger button with the selected Lucide icon

+  <action>
+    **CategoryPicker.tsx:**
+    1. Replace `import { EmojiPicker }` with `import { IconPicker }` from `./IconPicker` and `import { LucideIcon }` from `../lib/iconData`.
+    2. Change state: `newCategoryEmoji` -> `newCategoryIcon`, default from `"📦"` to `"package"`.
+    3. In `handleConfirmCreate`: Change `{ name, emoji: newCategoryIcon }` to `{ name, icon: newCategoryIcon }`.
+    4. In click-outside handler: Change `data-emoji-picker` check to `data-icon-picker`.
+    5. Reset: Change all `setNewCategoryEmoji("📦")` to `setNewCategoryIcon("package")`.
+    6. In the combobox input display (when closed): Replace `${selectedCategory.emoji} ` text prefix with nothing — instead, add a LucideIcon before the input or use a different display approach. Best approach: when not open and a category is selected, show a small LucideIcon (size 16, className="text-gray-500 inline") before the category name in the input value.
+
+    Actually, for simplicity with the input element, render the icon as a visual prefix:
+    - Wrap input in a div with `relative` positioning
+    - Add a `LucideIcon` absolutely positioned on the left (pl-8 on input for padding)
+    - Input value when closed: just `selectedCategory.name` (no emoji prefix)
+    - Only show the icon prefix when a category is selected and dropdown is closed
+
+    7. In the dropdown list items: Replace `{cat.emoji} {cat.name}` with `<LucideIcon name={cat.icon} size={16} className="inline-block mr-1.5 text-gray-500" /> {cat.name}`.
+    8. In the inline create flow: Replace `<EmojiPicker value={newCategoryEmoji} onChange={setNewCategoryEmoji} size="sm" />` with `<IconPicker value={newCategoryIcon} onChange={setNewCategoryIcon} size="sm" />`.
+
+    **CategoryHeader.tsx:**
+    1. Replace `import { EmojiPicker }` with `import { IconPicker }` from `./IconPicker` and `import { LucideIcon }` from `../lib/iconData`.
+    2. Props: rename `emoji` to `icon` (type stays string).
+    3. State: `editEmoji` -> `editIcon`.
+    4. In `handleSave`: Change `emoji: editEmoji` to `icon: editIcon`.
+    5. Edit mode: Replace `<EmojiPicker value={editEmoji} onChange={setEditEmoji} size="sm" />` with `<IconPicker value={editIcon} onChange={setEditIcon} size="sm" />`.
+    6. Display mode: Replace `<span className="text-xl">{emoji}</span>` with `<LucideIcon name={icon} size={22} className="text-gray-500" />`.
+    7. Edit button onClick: Change `setEditEmoji(emoji)` to `setEditIcon(icon)`.
+
+    **OnboardingWizard.tsx:**
+    1. Replace `import { EmojiPicker }` with `import { IconPicker }` from `./IconPicker`.
+    2. State: `categoryEmoji` -> `categoryIcon`, default from `""` to `""` (empty is fine, picker shows "+").
+    3. In `handleCreateCategory`: Change `emoji: categoryEmoji.trim() || undefined` to `icon: categoryIcon.trim() || undefined`.
+    4. In step 2 JSX: Change label from "Emoji (optional)" to "Icon (optional)". Replace `<EmojiPicker value={categoryEmoji} onChange={setCategoryEmoji} size="md" />` with `<IconPicker value={categoryIcon} onChange={setCategoryIcon} size="md" />`.
+
+    **CreateThreadModal.tsx:**
+    1. Import `LucideIcon` from `../lib/iconData`.
+    2. In the category list: Replace `{cat.emoji} {cat.name}` with `<LucideIcon name={cat.icon} size={16} className="inline-block mr-1.5 text-gray-500" /> {cat.name}`.

+# Phase 6 Plan 2: Category Icon UI Components Summary
+
+**IconPicker component with search/group tabs and all category create/edit/display flows migrated from emoji to Lucide icons**
+
+## Performance
+
+- **Duration:** 5 min
+- **Started:** 2026-03-15T16:53:11Z
+- **Completed:** 2026-03-15T16:58:04Z
+- **Tasks:** 2
+- **Files modified:** 9
+
+## Accomplishments
+- Created IconPicker component with portal popover, search filtering, 8 group tabs, and 6-column icon grid
+- Replaced EmojiPicker with IconPicker in CategoryPicker, CategoryHeader, and OnboardingWizard
+- Updated CategoryPicker to show LucideIcon prefix in input and dropdown list items
+- Build succeeds with no TypeScript errors
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Create IconPicker component** - `59d1c89` (feat)
+2. **Task 2: Update CategoryPicker, CategoryHeader, OnboardingWizard, and CreateThreadModal** - `570bcea` (feat)
+
+## Files Created/Modified
+- `src/client/components/IconPicker.tsx` - New portal-based Lucide icon picker with search and group tabs
+- `src/client/components/CategoryPicker.tsx` - Uses IconPicker for inline create, LucideIcon for display
+- `src/client/components/CategoryHeader.tsx` - LucideIcon in view mode, IconPicker in edit mode
+- `src/client/components/OnboardingWizard.tsx` - IconPicker for category creation step
+- `src/client/components/CreateThreadModal.tsx` - Removed emoji from category select options
+- `src/client/hooks/useCategories.ts` - Fixed emoji -> icon in useUpdateCategory type
+- `src/client/routes/collection/index.tsx` - Fixed categoryEmoji -> categoryIcon references
+- `src/client/routes/setups/$setupId.tsx` - Fixed categoryEmoji -> categoryIcon references
+- `src/client/routes/threads/$threadId.tsx` - Fixed categoryEmoji -> categoryIcon reference
+
+## Decisions Made
+- Native HTML `<select>` elements cannot render React components, so category select dropdowns show name only (no icon prefix)
+- IconPicker uses 6-column grid instead of EmojiPicker's 8-column for better visibility of icons at 20px
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 3 - Blocking] Fixed categoryEmoji -> categoryIcon in collection and setup routes**
+- **Found during:** Task 2
+- **Issue:** Routes passed `emoji={categoryEmoji}` to CategoryHeader and used `item.categoryEmoji` which no longer exists after Plan 01 renamed the field
+- **Fix:** Updated all `categoryEmoji` references to `categoryIcon` and `emoji=` prop to `icon=` in collection/index.tsx, setups/$setupId.tsx, and threads/$threadId.tsx
+- **Files modified:** src/client/routes/collection/index.tsx, src/client/routes/setups/$setupId.tsx, src/client/routes/threads/$threadId.tsx
+- **Verification:** Build succeeds
+- **Committed in:** 570bcea (Task 2 commit)
+
+**2. [Rule 3 - Blocking] Fixed useUpdateCategory hook type from emoji to icon**
+- **Found during:** Task 2
+- **Issue:** useUpdateCategory mutationFn type still had `emoji?: string` instead of `icon?: string`
+- **Fix:** Changed type to `icon?: string`
+- **Files modified:** src/client/hooks/useCategories.ts
+- **Verification:** Build succeeds
+- **Committed in:** 570bcea (Task 2 commit)
+
+---
+
+**Total deviations:** 2 auto-fixed (2 blocking)
+**Impact on plan:** Both fixes were necessary for build to pass after Plan 01 renamed emoji to icon. No scope creep.
+
+## Issues Encountered
+None
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
+- IconPicker and all category create/edit components complete
+- EmojiPicker.tsx and emojiData.ts can be removed in Plan 03 (cleanup)
+- Some display components (ItemCard, ThreadCard, etc.) were already updated in Plan 01

+# Phase 6 Plan 3: Display Component Icon Migration Summary
+
+**Migrated all display components from emoji text to LucideIcon rendering with consistent sizing across cards, badges, and headers**
+
+## Performance
+
+- **Duration:** 6 min
+- **Started:** 2026-03-15T16:53:10Z
+- **Completed:** 2026-03-15T16:59:16Z
+- **Tasks:** 2
+- **Files modified:** 13
+
+## Accomplishments
+- Replaced emoji text rendering with LucideIcon components in ItemCard, CandidateCard, ThreadCard, and ItemPicker
+- Updated all client-side hook interfaces from categoryEmoji to categoryIcon to match server API
+- Updated route files to pass icon prop to CategoryHeader and categoryIcon to card components
+- Removed old EmojiPicker.tsx and emojiData.ts files, zero emoji references remain
+- All 87 tests pass, build succeeds
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Update display components to use categoryIcon with LucideIcon** - `615c894` (feat)
+2. **Task 2: Update route files and delete old emoji files** - `9fcb07c` (chore)
+
+## Files Created/Modified
+- `src/client/components/ItemCard.tsx` - Renders LucideIcon at 36px in placeholder, 14px in badge
+- `src/client/components/CandidateCard.tsx` - Same LucideIcon pattern as ItemCard
+- `src/client/components/ThreadCard.tsx` - Renders LucideIcon at 16px next to category name
+- `src/client/components/ItemPicker.tsx` - Shows LucideIcon next to category group headers
+- `src/client/hooks/useItems.ts` - Interface: categoryEmoji -> categoryIcon
+- `src/client/hooks/useThreads.ts` - Interfaces: categoryEmoji -> categoryIcon in ThreadListItem and CandidateWithCategory
+- `src/client/hooks/useSetups.ts` - Interface: categoryEmoji -> categoryIcon
+- `src/client/hooks/useTotals.ts` - Interface: categoryEmoji -> categoryIcon
+- `src/client/hooks/useCategories.ts` - Mutation type: emoji -> icon
+- `src/client/lib/iconData.tsx` - Renamed from .ts to .tsx (contains JSX)
+- `src/client/routes/collection/index.tsx` - Passes icon to CategoryHeader, categoryIcon to cards
+- `src/client/routes/setups/$setupId.tsx` - Same icon prop updates
+- `src/client/routes/threads/$threadId.tsx` - Passes categoryIcon to CandidateCard
+
+## Decisions Made
+- Renamed iconData.ts to iconData.tsx since it contains JSX and the production build (rolldown) requires proper .tsx extension for JSX parsing
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 3 - Blocking] Updated client hook interfaces to match server API**
+- **Found during:** Task 1 (display component updates)
+- **Issue:** Client-side TypeScript interfaces in hooks still referenced categoryEmoji but server API returns categoryIcon after Plan 01 migration
+- **Fix:** Updated interfaces in useItems, useThreads, useSetups, useTotals, and useCategories hooks
+- **Files modified:** 5 hook files
+- **Verification:** Build succeeds, types match API responses
+- **Committed in:** 615c894 (Task 1 commit)
+
+**2. [Rule 1 - Bug] Renamed iconData.ts to iconData.tsx**
+- **Found during:** Task 1 (build verification)
+- **Issue:** iconData.ts contains JSX (LucideIcon component) but had .ts extension, causing rolldown parse error during production build
+- **Fix:** Renamed file to .tsx
+- **Files modified:** src/client/lib/iconData.tsx (renamed from .ts)
+- **Verification:** Build succeeds
+- **Committed in:** 615c894 (Task 1 commit)
+
+---
+
+**Total deviations:** 2 auto-fixed (1 blocking, 1 bug)
+**Impact on plan:** Both fixes necessary for build correctness. No scope creep.
+
+## Issues Encountered
+- Plan 02 (IconPicker + component updates) had partial uncommitted work in the working tree. The CategoryHeader, CategoryPicker, OnboardingWizard, and CreateThreadModal were already updated to use icon/IconPicker. These changes were committed as part of the pre-commit flow.
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
+- Category icon migration is complete across all layers: database, API, and UI
+- All components render Lucide icons consistently
+- Phase 6 is fully complete
+
+## Self-Check: PASSED
+
+All created files verified, all commits found, zero emoji references confirmed.

+# Phase 6: Category Icons - Context
+
+**Gathered:** 2026-03-15
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+Replace the emoji-based category icon system with Lucide icons. Build an icon picker component, update all display points throughout the app, migrate existing emoji categories to equivalent Lucide icons via database migration, and clean up the old emoji code. No new category features (color coding, nesting, reordering) — those would be separate phases.
+
+</domain>
+
+<decisions>
+## Implementation Decisions
+
+### Icon picker UX
+- Same portal-based popover pattern as current EmojiPicker (positioning, click-outside, escape, scroll)
+- Search bar + category tab navigation (tabs = icon groups)
+- Icon grid with Lucide icons rendered at consistent size
+- Trigger button: selected icon in bordered square box, or "+" when empty (same dimensions as current EmojiPicker trigger)
+- CategoryPicker combobox shows Lucide icon + name inline for each category (replacing emoji + name)
+- CategoryPicker's inline create flow uses new IconPicker instead of EmojiPicker
+
+### Icon display style
+- Color: gray tones matching surrounding text (gray-500/600) — subtle, minimalist
+- Stroke weight: default 2px (Lucide standard)
+- Sizes: context-matched — ~20px in headers, ~16px in card badges/pills, ~14px inline in lists
+- Card image placeholder areas (from Phase 5): Lucide category icon at ~32-40px on gray background, replacing emoji
+- No color per category — all icons use same gray tones
+
+### Emoji migration
+- Automatic mapping table: emoji → Lucide icon name (e.g. 🏕→'tent', 🚲→'bike', 📷→'camera', 📦→'package')
+- Unmapped emoji fall back to 'package' icon
+- Uncategorized category (id=1): 📦 maps to 'package'
+- Database column renamed from `emoji` (text) to `icon` (text), storing Lucide icon name strings
+- Default value changes from "📦" to "package"
+- Migration runs during `bun run db:push` — one-time schema change with data conversion
+
+### Icon subset
+- Curated subset of ~80-120 gear-relevant Lucide icons
+- Organized into groups that match picker tabs: Outdoor, Travel, Sports, Electronics, Clothing, Tools, General
+- Groups serve as both picker tabs and browsing categories
+- Search filters across all groups
+
+### Cleanup
+- Old EmojiPicker.tsx and emojiData.ts fully removed after migration
+- No emoji references remain anywhere in the codebase
+- OnboardingWizard default categories updated to use Lucide icon names
+
+### Claude's Discretion
+- Exact icon selections for each curated group
+- Icon data file structure (static data file similar to emojiData.ts or alternative)
+- Migration script implementation details
+- Exact emoji-to-icon mapping table completeness
+- Popover sizing and grid column count
+- Search algorithm (fuzzy vs exact match on icon names)
+
+</decisions>
+
+<code_context>
+## Existing Code Insights
+
+### Reusable Assets
+- `EmojiPicker` component (`src/client/components/EmojiPicker.tsx`): 215-line component with portal popover, search, category tabs, click-outside, escape handling — architecture to replicate for IconPicker
+- `CategoryPicker` (`src/client/components/CategoryPicker.tsx`): Combobox with search, keyboard nav, inline create — needs EmojiPicker → IconPicker swap
+- `CategoryHeader` (`src/client/components/CategoryHeader.tsx`): Edit mode uses EmojiPicker — needs IconPicker swap
+- `emojiData.ts` (`src/client/lib/emojiData.ts`): Data structure pattern to replicate for icon groups
+
+### Established Patterns
+- Portal-based popover rendering via `createPortal` (EmojiPicker)
+- Click-outside detection via document mousedown listener
+- Category data flows: `useCategories` hook → components render `cat.emoji` everywhere
+- Drizzle ORM schema in `src/db/schema.ts` — `emoji` column on categories table
+- `@hono/zod-validator` for request validation — `createCategorySchema` in schemas.ts
+
+### Integration Points
+- `src/db/schema.ts`: Rename `emoji` column to `icon`, change default from "📦" to "package"
+- `src/shared/schemas.ts`: Update category schemas (field name emoji → icon)
+- `src/shared/types.ts`: Types inferred from schemas — will auto-update
+- `src/server/services/category.service.ts`: Update service functions
+- `src/server/routes/categories.ts`: Update route handlers if needed
+- `src/client/components/CategoryHeader.tsx`: Replace EmojiPicker with IconPicker, emoji → icon prop
+- `src/client/components/CategoryPicker.tsx`: Replace EmojiPicker with IconPicker, emoji → icon display
+- `src/client/components/ItemCard.tsx`: Replace `categoryEmoji` prop with `categoryIcon`, render Lucide icon
+- `src/client/components/CandidateCard.tsx`: Same as ItemCard
+- `src/client/components/ThreadCard.tsx`: Category icon display
+- `src/client/components/OnboardingWizard.tsx`: Default categories use icon names instead of emoji
+- `src/client/routes/collection/index.tsx`: Category display in collection view
+- `src/client/routes/index.tsx`: Dashboard category display
+- `src/db/seed.ts`: Seed data emoji → icon
+- `tests/helpers/db.ts`: Update test helper CREATE TABLE and seed data
+
+</code_context>
+
+<specifics>
+## Specific Ideas
+
+- Icon picker should feel like a natural evolution of the EmojiPicker — same popover behavior, just rendering Lucide SVGs instead of emoji characters
+- Curated icon groups should focus on gear/hobby relevance: outdoor camping, cycling, travel, electronics, clothing, tools
+- The migration mapping should cover common gear emoji (tent, bike, backpack, camera, etc.) with 'package' as the universal fallback
+- After migration, zero emoji should remain — fully consistent Lucide icon experience
+
+</specifics>
+
+<deferred>
+## Deferred Ideas
+
+None — discussion stayed within phase scope

+### Requirements Coverage
+
+| Requirement | Source Plan | Description | Status | Evidence |
+|-------------|------------|-------------|--------|----------|
+| CAT-01 | 06-02 | User can select a Lucide icon when creating/editing a category (icon picker) | SATISFIED | IconPicker component exists and is wired into CategoryPicker, CategoryHeader, and OnboardingWizard |
+| CAT-02 | 06-03 | Category icons display as Lucide icons throughout the app (cards, headers, lists) | SATISFIED | ItemCard, CandidateCard, ThreadCard, ItemPicker, CategoryHeader all render LucideIcon with categoryIcon prop |
+| CAT-03 | 06-01 | Existing emoji categories are migrated to equivalent Lucide icons | SATISFIED | Migration SQL `0001_rename_emoji_to_icon.sql` renames column and converts emoji values to icon names |
+
+### Anti-Patterns Found
+
+| File | Line | Pattern | Severity | Impact |
+|------|------|---------|----------|--------|
+| `src/client/routes/collection/index.tsx` | 64 | `<div className="text-5xl mb-4">🎒</div>` emoji in empty state | Info | Decorative emoji in the gear collection empty state (not a category icon) — outside phase scope |
+
+The single emoji found is a decorative `🎒` in the collection empty state UI — it is not a category icon and is not part of the data model. Zero `categoryEmoji`, `EmojiPicker`, or `emojiData` references remain.
+
+### Human Verification Required
+
+#### 1. IconPicker Popover Visual Layout
+
+**Test:** Navigate to any category create/edit flow (CategoryPicker inline create, or CategoryHeader edit mode). Click the icon trigger button.
+**Expected:** Popover opens below the trigger with a search input at top, 8 group tab icons, and a 6-column icon grid. Clicking a group tab switches the icon set. Typing in search filters icons in real time. Clicking an icon selects it and closes the popover.
+**Why human:** Portal-based popover positioning and interactive search filtering cannot be confirmed by static analysis.
+
+#### 2. Onboarding Icon Selection
+
+**Test:** Clear the `onboardingComplete` setting (or use a fresh DB) and walk through onboarding step 2.
+**Expected:** "Icon (optional)" label appears above an IconPicker trigger button (not an EmojiPicker). Selecting an icon and creating the category persists the icon name in the database.
+**Why human:** End-to-end flow through a stateful wizard; requires runtime execution.
+
+#### 3. Category Filter Dropdown (Known Limitation)
+
+**Test:** Navigate to collection > planning tab. Check the category filter dropdown (top-right of the planning view).
+**Expected:** The dropdown shows category names only (no icons). This is a confirmed known limitation documented in the 06-02 SUMMARY — native HTML `<select>` cannot render React components.
+**Why human:** Requirement CAT-02 says icons display "throughout the app." The filter dropdown does not render icons. This is a deliberate deviation due to HTML constraints, not a bug, but human review confirms the trade-off is acceptable.
+
+### Gaps Summary
+
+No gaps. All 16 observable truths are verified in the codebase.
+
+The one known limitation — category filter dropdown shows names only without icons — was a deliberate decision documented in the 06-02 SUMMARY ("Native HTML select cannot render React components"). The plan's task instructions acknowledged this. CAT-02 is satisfied by all card, header, list, and picker surfaces; the filter select is the only exception.

+- **SOCL-01**: User can create an account with authentication
+- **SOCL-02**: User can share collections and setups publicly
+- **SOCL-03**: User can view other users' public profiles and setups
+
+### Automation
+
+- **AUTO-01**: System can auto-fill product information (price, weight, images) from external sources
+
+## Out of Scope
+
+Explicitly excluded. Documented to prevent scope creep.
+
+| Feature | Reason |
+|---------|--------|
+| Per-item weight input in multiple units | Parsing complexity, ambiguous storage -- display-only conversion is sufficient |
+| Interactive chart drill-down (click to zoom) | Adds significant interaction complexity for minimal value |
+| Weight goals / targets | Opinionated norms conflict with hobby-agnostic design |
+| Custom classification labels | base/worn/consumable covers 95% of use cases |
+| Server-side full-text search | Premature for single-user app with <1000 items |
+| Classification at item level (not setup level) | Same item has different roles in different setups |
+| Status change timestamps | Useful but adds schema complexity -- defer |

+
+### v1.2 Collection Power-Ups (In Progress)
+
+**Milestone Goal:** Make core gear management significantly more useful as collections grow -- better search, proper weight classification, richer planning threads.
+
+- [x] **Phase 7: Weight Unit Selection** - Users see all weights in their preferred unit across the entire app
+- [x] **Phase 8: Search, Filter, and Candidate Status** - Users can find items quickly and track candidate purchase progress
+- [x] **Phase 9: Weight Classification and Visualization** - Users can classify gear by role and visualize weight distribution in setups
+
+## Phase Details
+
+### Phase 7: Weight Unit Selection
+**Goal**: Users see all weights in their preferred unit across the entire app
+**Depends on**: Nothing (first phase of v1.2)
+**Requirements**: UNIT-01, UNIT-02, UNIT-03
+**Success Criteria** (what must be TRUE):
+  1. User can select a weight unit (g, oz, lb, kg) from a visible control and the selection persists after closing and reopening the app
+  2. Every weight value in the app (item cards, candidate cards, category headers, totals bar, setup details) displays in the selected unit with appropriate precision
+  3. Weight input fields accept values and store them correctly regardless of display unit (no rounding drift across edit cycles)
+**Plans:** 2 plans
+
+Plans:
+- [x] 07-01-PLAN.md -- TDD formatWeight unit conversion core + useWeightUnit hook
+- [ ] 07-02-PLAN.md -- Wire unit toggle into TotalsBar and update all 8 call sites
+
+### Phase 8: Search, Filter, and Candidate Status
+**Goal**: Users can find items quickly and track candidate purchase progress
+**Depends on**: Phase 7
+**Requirements**: SRCH-01, SRCH-02, SRCH-03, SRCH-04, SRCH-05, PLAN-01, CAND-01, CAND-02, CAND-03
+**Success Criteria** (what must be TRUE):
+  1. User can type in a search field on the collection page and see items filtered instantly by name as they type
+  2. User can select a category from a dropdown (showing Lucide icons alongside names) to filter items in both collection and planning views
+  3. User can see how many items match active filters (e.g., "showing 12 of 47 items") and clear all filters with one action
+  4. Each candidate in a planning thread displays a status badge (researching, ordered, or arrived) that the user can change by clicking
+  5. New candidates automatically start with "researching" status
+**Plans:** 2 plans
+
+Plans:
+- [ ] 08-01-PLAN.md -- Candidate status vertical slice (schema migration, service, tests, StatusBadge UI)
+- [ ] 08-02-PLAN.md -- Search/filter toolbar with CategoryFilterDropdown on gear and planning tabs
+
+### Phase 9: Weight Classification and Visualization
+**Goal**: Users can classify gear by role and visualize weight distribution in setups
+**Depends on**: Phase 7, Phase 8
+**Requirements**: CLAS-01, CLAS-02, CLAS-03, CLAS-04, VIZZ-01, VIZZ-02, VIZZ-03
+**Success Criteria** (what must be TRUE):
+  1. User can classify each item within a setup as base weight, worn, or consumable, and the same item can have different classifications in different setups
+  2. Setup detail view shows separate weight subtotals for base weight, worn weight, and consumable weight in addition to the overall total
+  3. User can view a donut chart in a setup showing weight distribution, and toggle between category breakdown and classification breakdown
+  4. User can hover chart segments to see the category/classification name, weight (in selected unit), and percentage
+**Plans:** 2 plans
+
+Plans:
+- [ ] 09-01-PLAN.md -- Classification vertical slice (schema, service, tests, API route, ClassificationBadge UI)
+- [ ] 09-02-PLAN.md -- WeightSummaryCard with subtotals, donut chart, pill toggle, and visual verification

+<objective>
+Create the weight unit conversion core: a parameterized `formatWeight` function with a `WeightUnit` type and a `useWeightUnit` convenience hook, all backed by tests.
+
+Purpose: Establish the conversion contracts (type, function, hook) that Plan 02 will wire into every component. TDD approach ensures the conversion math is correct before any UI work.
+Output: Working `formatWeight(grams, unit)` with tests green, `useWeightUnit()` hook ready for consumption.

+# Phase 7 Plan 01: Weight Unit Core Summary
+
+**Parameterized formatWeight with g/oz/lb/kg conversion and useWeightUnit settings hook, backed by 21 TDD tests**
+
+## Performance
+
+- **Duration:** 2 min
+- **Started:** 2026-03-16T11:14:19Z
+- **Completed:** 2026-03-16T11:16:30Z
+- **Tasks:** 2
+- **Files modified:** 3
+
+## Accomplishments
+- TDD-developed formatWeight function supporting 4 weight units (g, oz, lb, kg) with appropriate precision
+- WeightUnit type exported for consumption by all display components in Plan 02
+- useWeightUnit convenience hook with validation and "g" default, ready for component integration
+- Full backward compatibility preserved -- formatWeight(grams) still returns "Xg" as before
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1 (RED): TDD formatWeight tests** - `431c179` (test)
+2. **Task 1 (GREEN): Implement formatWeight with unit parameter** - `6cac0a3` (feat)
+3. **Task 2: Create useWeightUnit convenience hook** - `ada3791` (feat)
+
+_TDD task had 2 commits (test -> feat). No refactor needed -- code was already minimal._
+
+## Files Created/Modified
+- `src/client/lib/formatters.ts` - Added WeightUnit type, conversion constants, switch-based unit formatting
+- `src/client/hooks/useWeightUnit.ts` - Convenience hook wrapping useSetting("weightUnit") with typed validation
+- `tests/lib/formatters.test.ts` - 21 tests covering all units, null/undefined, backward compat, edge cases
+
+## Decisions Made
+- Conversion precision follows common usage: grams rounded (0dp), ounces 1dp, pounds 2dp, kilograms 2dp
+- useWeightUnit validates stored value against a whitelist of known units, protecting against corrupt settings data
+- Conversion constants (GRAMS_PER_OZ=28.3495, GRAMS_PER_LB=453.592, GRAMS_PER_KG=1000) kept as module-level consts, not exported
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] Fixed import order in useWeightUnit.ts**
+- **Found during:** Task 2 (useWeightUnit hook creation)
+- **Issue:** Biome lint required imports sorted alphabetically (type imports before value imports)
+- **Fix:** Reordered imports to put `import type { WeightUnit }` before `import { useSetting }`
+- **Files modified:** src/client/hooks/useWeightUnit.ts
+- **Verification:** `bun run lint` passes clean
+- **Committed in:** ada3791 (Task 2 commit)
+
+---
+
+**Total deviations:** 1 auto-fixed (1 bug - lint order)
+**Impact on plan:** Trivial formatting fix. No scope creep.
+
+## Issues Encountered
+None
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
+- WeightUnit type and formatWeight function ready for Plan 02 to wire into all weight-displaying components
+- useWeightUnit hook ready for components to consume the user's preferred unit from settings
+- All 108 existing tests pass (full suite regression check confirmed)
+
+## Self-Check: PASSED
+
+All files exist, all commits found, all exports verified.

+<objective>
+Wire weight unit selection through the entire app: add a segmented unit toggle to TotalsBar and update all 8 formatWeight call sites to use the selected unit.
+
+Purpose: Deliver the complete user-facing feature. After this plan, users can select g/oz/lb/kg and see all weights update instantly across collection, planning, setups, and dashboard.
+Output: Fully functional weight unit selection with persistent preference.

+  </files>
+  <action>
+    **TotalsBar.tsx** -- Add unit toggle and wire formatWeight:
+
+    1. Import `useWeightUnit` from `../hooks/useWeightUnit`, `useUpdateSetting` from `../hooks/useSettings`, and `WeightUnit` type from `../lib/formatters`
+    2. Inside the component function, call `const unit = useWeightUnit()` and `const updateSetting = useUpdateSetting()`
+    3. Define `const UNITS: WeightUnit[] = ["g", "oz", "lb", "kg"]`
+    4. Add a segmented pill toggle to the right side of the TotalsBar, between the title and the stats. The toggle should be a `div` with `flex items-center gap-1 bg-gray-100 rounded-full px-1 py-0.5` containing a button per unit:
+       ```
+       <button
+         key={u}
+         onClick={() => updateSetting.mutate({ key: "weightUnit", value: u })}
+         className={`px-2 py-0.5 text-xs rounded-full transition-colors ${
+           unit === u
+             ? "bg-white text-gray-700 shadow-sm font-medium"
+             : "text-gray-400 hover:text-gray-600"
+         }`}
+       >
+         {u}
+       </button>
+       ```
+    5. Update the default stats construction (the `data?.global` branch) to pass `unit` to both `formatWeight` calls:
+       - `formatWeight(data.global.totalWeight, unit)` and `formatWeight(null, unit)`
+    6. Position the toggle: place it in the flex container between the title and stats, using a wrapper div that pushes stats to the right. The toggle should be visible but not dominant -- it's a small utility control.
+
+    **ItemCard.tsx** -- 3-line change:
+    1. Add import: `import { useWeightUnit } from "../hooks/useWeightUnit";`
+    2. Inside component: `const unit = useWeightUnit();`
+    3. Change `{formatWeight(weightGrams)}` to `{formatWeight(weightGrams, unit)}`
+
+    **CandidateCard.tsx** -- Same 3-line pattern as ItemCard:
+    1. Add import: `import { useWeightUnit } from "../hooks/useWeightUnit";`
+    2. Inside component: `const unit = useWeightUnit();`
+    3. Change `{formatWeight(weightGrams)}` to `{formatWeight(weightGrams, unit)}`
+
+    **CategoryHeader.tsx** -- Same 3-line pattern:
+    1. Add import: `import { useWeightUnit } from "../hooks/useWeightUnit";`
+    2. Inside component: `const unit = useWeightUnit();`
+    3. Change `{formatWeight(totalWeight)}` to `{formatWeight(totalWeight, unit)}`
+
+    **SetupCard.tsx** -- Same 3-line pattern:
+    1. Add import: `import { useWeightUnit } from "../hooks/useWeightUnit";`
+    2. Inside component: `const unit = useWeightUnit();`
+    3. Change `{formatWeight(totalWeight)}` to `{formatWeight(totalWeight, unit)}`
+
+    **ItemPicker.tsx** -- Same 3-line pattern:
+    1. Add import: `import { useWeightUnit } from "../hooks/useWeightUnit";`
+    2. Inside component: `const unit = useWeightUnit();`
+    3. Change `formatWeight(item.weightGrams)` to `formatWeight(item.weightGrams, unit)`
+
+    **routes/index.tsx** (Dashboard) -- Same 3-line pattern:
+    1. Add import: `import { useWeightUnit } from "../hooks/useWeightUnit";`
+    2. Inside `DashboardPage`: `const unit = useWeightUnit();`
+    3. Change `formatWeight(global?.totalWeight ?? null)` to `formatWeight(global?.totalWeight ?? null, unit)`
+
+    **routes/setups/$setupId.tsx** (Setup Detail) -- Same 3-line pattern:
+    1. Add import: `import { useWeightUnit } from "../../hooks/useWeightUnit";`
+    2. Inside `SetupDetailPage`: `const unit = useWeightUnit();`
+    3. Change `{formatWeight(totalWeight)}` to `{formatWeight(totalWeight, unit)}`

+# Phase 7 Plan 02: Weight Unit UI Wiring Summary
+
+**Segmented g/oz/lb/kg toggle in TotalsBar with all 8 weight display call sites wired to user-selected unit**
+
+## Performance
+
+- **Duration:** 3 min
+- **Started:** 2026-03-16T11:20:20Z
+- **Completed:** 2026-03-16T11:23:32Z
+- **Tasks:** 2 (1 auto + 1 checkpoint auto-approved)
+- **Files modified:** 8
+
+## Accomplishments
+- Added segmented pill toggle (g/oz/lb/kg) to TotalsBar with persistent settings via useUpdateSetting
+- Wired all 8 formatWeight call sites to pass the selected unit from useWeightUnit hook
+- All 108 existing tests pass with no regressions, lint clean
+
+## Task Commits

+Each task was committed atomically:
+
+1. **Task 1: Add unit toggle to TotalsBar and update all call sites** - `faa4378` (feat)
+2. **Task 2: Verify weight unit selection end-to-end** - auto-approved (checkpoint)
+
+## Files Created/Modified
+- `src/client/components/TotalsBar.tsx` - Added unit toggle UI, useUpdateSetting mutation, and unit-aware formatWeight calls
+- `src/client/components/ItemCard.tsx` - Added useWeightUnit import and unit parameter to formatWeight
+- `src/client/components/CandidateCard.tsx` - Added useWeightUnit import and unit parameter to formatWeight

+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] Fixed import order for WeightUnit type in TotalsBar.tsx**
+- **Found during:** Task 1 (TotalsBar modification)
+- **Issue:** Biome lint required `type WeightUnit` to come after value imports in destructured import
+- **Fix:** Changed `{ type WeightUnit, formatPrice, formatWeight }` to `{ formatPrice, formatWeight, type WeightUnit }`
+- **Files modified:** src/client/components/TotalsBar.tsx
+- **Verification:** `bun run lint` passes clean
+- **Committed in:** faa4378 (Task 1 commit)
+
+---
+
+**Total deviations:** 1 auto-fixed (1 bug - lint import ordering)
+**Impact on plan:** Trivial import ordering fix. No scope creep.
+
+## Issues Encountered
+None
+
+## User Setup Required

+# Phase 7: Weight Unit Selection - Context
+
+**Gathered:** 2026-03-16
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+Users can select a preferred weight unit (g, oz, lb, kg) and all weight displays across the app reflect that choice. Weight input stays in grams. The setting persists across sessions.
+
+</domain>
+
+<decisions>
+## Implementation Decisions
+
+### Claude's Discretion
+- Unit selector placement (TotalsBar, settings page, or elsewhere)
+- Pounds display format (traditional "2 lb 3 oz" vs decimal "2.19 lb")
+- Precision per unit (decimal places for oz, kg)
+- Default unit (grams, matching current behavior)
+- How formatWeight gets access to the setting (hook, context, parameter)
+
+</decisions>
+
+<code_context>
+## Existing Code Insights
+
+### Reusable Assets
+- `formatWeight()` in `src/client/lib/formatters.ts`: Currently `Math.round(grams) + "g"` — single conversion point for all weight display
+- `useSetting(key)` hook in `src/client/hooks/useSettings.ts`: Fetches from `/api/settings/:key`, caches with React Query
+- `useUpdateSetting()` mutation: PUT to `/api/settings/:key`, invalidates query cache
+- Settings API already exists with get/put endpoints
+
+### Established Patterns
+- Settings stored as key/value strings in SQLite `settings` table
+- React Query for server state, Zustand for UI-only state
+- Pill badges for weight/price display on ItemCard and CandidateCard (blue-50/blue-400 for weight)
+
+### Integration Points
+- `formatWeight()` call sites (~8 components): TotalsBar, ItemCard, CandidateCard, CategoryHeader, SetupCard, ItemPicker, collection route, setup detail route
+- `formatPrice()` is in the same file — similar pattern, not affected by this phase
+- TotalsBar already imports `useTotals()` and `formatWeight` — natural place for a unit toggle

+# Phase 7: Weight Unit Selection - Research
+
+**Researched:** 2026-03-16
+**Domain:** Weight unit conversion, display formatting, settings persistence
+**Confidence:** HIGH
+
+## Summary
+
+This phase is a display-only concern with a clean architecture. All weight data is already stored in grams (`weight_grams REAL` in SQLite). The task is to: (1) let the user pick a display unit, (2) persist that choice via the existing settings system, and (3) modify `formatWeight()` to convert grams to the selected unit before rendering. The existing `useSetting`/`useUpdateSetting` hooks and `/api/settings/:key` API handle persistence out of the box -- no schema changes or migrations needed.
+
+The codebase has a single `formatWeight(grams)` function in `src/client/lib/formatters.ts` called from exactly 8 components. Every weight display flows through this function, so the conversion is a single-point change. The challenge is threading the unit preference to `formatWeight` -- currently a pure function with no access to React state. The cleanest approach is to add a `unit` parameter and create a `useWeightUnit()` hook that components use to get the current unit, then pass it to `formatWeight`.
+
+**Primary recommendation:** Add a `unit` parameter to `formatWeight(grams, unit)`, create a `useWeightUnit()` convenience hook wrapping `useSetting("weightUnit")`, and place a small unit toggle in the TotalsBar. Keep weight input always in grams -- this is a display-only feature per the requirements and out-of-scope list.

+## Phase Requirements
+
+| ID | Description | Research Support |
+|----|-------------|-----------------|
+| UNIT-01 | User can select preferred weight unit (g, oz, lb, kg) from settings | Settings API already exists; `useSetting`/`useUpdateSetting` hooks ready; unit selector component needed in TotalsBar |
+| UNIT-02 | All weight displays across the app reflect the selected unit | Single `formatWeight()` function is the sole conversion point; 8 call sites across TotalsBar, ItemCard, CandidateCard, CategoryHeader, SetupCard, ItemPicker, collection route, setup detail route |
+| UNIT-03 | Weight unit preference persists across sessions | `settings` table + `/api/settings/:key` upsert endpoint already handle this -- just use key `"weightUnit"` |
+</phase_requirements>
+
+## Standard Stack
+
+### Core
+| Library | Version | Purpose | Why Standard |
+|---------|---------|---------|--------------|
+| React 19 | 19.x | UI framework | Already in project |
+| TanStack React Query | 5.x | Server state / caching | Already used for all data fetching; `useSetting` hook wraps it |
+| Hono | 4.x | API server | Settings routes already exist |
+| Drizzle ORM | latest | Database access | Settings table already defined |
+
+### Supporting
+No additional libraries needed. This phase requires zero new dependencies.
+
+### Alternatives Considered
+| Instead of | Could Use | Tradeoff |
+|------------|-----------|----------|
+| Parameter-based `formatWeight(g, unit)` | React Context provider | Context adds unnecessary complexity for a single value; parameter is explicit, testable, and avoids re-render cascades |
+| Zustand store for unit | `useSetting` hook (React Query) | Unit is server-persisted state, not ephemeral UI state; React Query is the correct layer per project conventions |
+
+## Architecture Patterns
+
+### Recommended Approach
+
+No new files except a small `useWeightUnit` convenience hook. The changes are surgical:
+
+```
+src/client/
+  lib/
+    formatters.ts         # MODIFY: add unit parameter to formatWeight
+  hooks/
+    useWeightUnit.ts      # NEW: convenience hook wrapping useSetting("weightUnit")
+  components/
+    TotalsBar.tsx          # MODIFY: add unit toggle control
+    ItemCard.tsx           # MODIFY: pass unit to formatWeight
+    CandidateCard.tsx      # MODIFY: pass unit to formatWeight
+    CategoryHeader.tsx     # MODIFY: pass unit to formatWeight
+    SetupCard.tsx          # MODIFY: pass unit to formatWeight
+    ItemPicker.tsx         # MODIFY: pass unit to formatWeight
+  routes/
+    index.tsx              # MODIFY: pass unit to formatWeight
+    setups/$setupId.tsx    # MODIFY: pass unit to formatWeight
+```
+
+### Pattern 1: Weight Unit Type and Conversion Constants
+
+**What:** Define a `WeightUnit` type and conversion map as a simple module constant.
+**When to use:** Everywhere unit-related logic is needed.
+**Example:**
+
+```typescript
+// In src/client/lib/formatters.ts
+export type WeightUnit = "g" | "oz" | "lb" | "kg";
+
+const GRAMS_PER_OZ = 28.3495;
+const GRAMS_PER_LB = 453.592;
+const GRAMS_PER_KG = 1000;
+
+export function formatWeight(
+  grams: number | null | undefined,
+  unit: WeightUnit = "g",
+): string {
+  if (grams == null) return "--";
+
+  switch (unit) {
+    case "g":
+      return `${Math.round(grams)}g`;
+    case "oz":
+      return `${(grams / GRAMS_PER_OZ).toFixed(1)} oz`;
+    case "lb":
+      return `${(grams / GRAMS_PER_LB).toFixed(2)} lb`;
+    case "kg":
+      return `${(grams / GRAMS_PER_KG).toFixed(2)} kg`;
+  }
+}
+```
+
+### Pattern 2: Convenience Hook
+
+**What:** A thin hook that reads the weight unit setting and returns a typed value with a sensible default.
+**When to use:** Any component that calls `formatWeight`.
+**Example:**
+
+```typescript
+// In src/client/hooks/useWeightUnit.ts
+import { useSetting } from "./useSettings";
+import type { WeightUnit } from "../lib/formatters";
+
+const VALID_UNITS: WeightUnit[] = ["g", "oz", "lb", "kg"];
+
+export function useWeightUnit(): WeightUnit {
+  const { data } = useSetting("weightUnit");
+  if (data && VALID_UNITS.includes(data as WeightUnit)) {
+    return data as WeightUnit;
+  }
+  return "g"; // default matches current behavior
+}
+```
+
+### Pattern 3: Unit Selector in TotalsBar
+
+**What:** A small segmented control or dropdown in the TotalsBar for switching units.
+**When to use:** Global weight unit selection, always visible.
+**Example concept:**
+
+```typescript
+// Segmented pill buttons in TotalsBar
+const UNITS: WeightUnit[] = ["g", "oz", "lb", "kg"];
+
+// Small inline toggle alongside stats

+
+### Anti-Patterns to Avoid
+- **Converting on the server side:** Database stores grams, API returns grams. Conversion is purely a display concern -- never modify the API layer.
+- **Using React Context for a single value:** The project uses React Query for server state. Adding a Context provider for one setting breaks convention and introduces unnecessary complexity.
+- **Storing converted values:** Always store grams in the database. The `weightUnit` setting is a display preference, not a data transformation.
+- **Changing weight input fields:** The requirements explicitly keep input in grams (see Out of Scope in REQUIREMENTS.md: "Per-item weight input in multiple units" is excluded). Input labels stay as "Weight (g)".
+
+## Don't Hand-Roll
+
+| Problem | Don't Build | Use Instead | Why |
+|---------|-------------|-------------|-----|
+| Setting persistence | Custom localStorage + API sync | Existing `useSetting`/`useUpdateSetting` hooks + settings API | Already handles cache invalidation and server persistence |
+| Unit conversion | Complex conversion library | Simple division constants (28.3495, 453.592, 1000) | Only 4 units, all linear conversions from grams -- a library is overkill |
+
+**Key insight:** The entire feature is a ~30-line formatter change + a small UI toggle + updating 8 call sites. No external library is needed.
+
+## Common Pitfalls
+
+### Pitfall 1: Floating-Point Display Precision
+**What goes wrong:** Showing too many decimal places (e.g., "42.328947 oz") or too few (e.g., "0 kg" for a 450g item).
+**Why it happens:** Different units have different natural precision ranges.
+**How to avoid:** Use unit-specific precision: `g` = 0 decimals (round), `oz` = 1 decimal, `lb` = 2 decimals, `kg` = 2 decimals. These match gear community conventions (LighterPack and similar apps use comparable precision).
+**Warning signs:** Items showing "0 lb" or "0.0 oz" when they have measurable weight.
+
+### Pitfall 2: Null/Undefined Weight Handling
+**What goes wrong:** Conversion math on null values produces NaN or "NaN oz".
+**Why it happens:** Many items have `weightGrams: null` (optional field).
+**How to avoid:** The existing `if (grams == null) return "--"` guard at the top of `formatWeight` handles this. Keep it as the first check before any unit logic.
+**Warning signs:** "NaN" or "undefined oz" appearing in the UI.
+
+### Pitfall 3: Forgetting a Call Site
+**What goes wrong:** One component still shows grams while everything else shows the selected unit.
+**Why it happens:** `formatWeight` is called in 8 different files. Missing one is easy.
+**How to avoid:** Grep for all `formatWeight` call sites. The complete list is: TotalsBar.tsx, ItemCard.tsx, CandidateCard.tsx, CategoryHeader.tsx, SetupCard.tsx, ItemPicker.tsx, `routes/index.tsx`, `routes/setups/$setupId.tsx`. Update all 8.
+**Warning signs:** Inconsistent unit display across different views.
+
+### Pitfall 4: Default Unit Breaks Existing Behavior
+**What goes wrong:** If the default isn't "g", existing users see different numbers on upgrade.
+**Why it happens:** No `weightUnit` setting exists in the database yet.
+**How to avoid:** Default to `"g"` when `useSetting("weightUnit")` returns null (404 from API). This preserves backward compatibility -- the app looks identical until the user changes the unit.
+**Warning signs:** Weights appearing in ounces on first load without user action.
+
+### Pitfall 5: Rounding Drift on Edit Cycles
+**What goes wrong:** User edits an item, weight displays as "42.3 oz", they save without changing weight, but the stored value shifts.
+**Why it happens:** Would only occur if input fields converted units. Since input stays in grams (per Out of Scope), this cannot happen.
+**How to avoid:** Keep all input fields showing grams. The label says "Weight (g)" and the stored value is always `weight_grams`. Display conversion is one-directional: grams -> display unit.
+**Warning signs:** N/A -- this is prevented by the "input stays in grams" design decision.
+
+### Pitfall 6: React Query Cache Staleness
+**What goes wrong:** User changes unit but some components still show the old unit until they re-render.
+**Why it happens:** The `useUpdateSetting` mutation invalidates `["settings", "weightUnit"]`, but components caching the old value might not immediately re-render.
+**How to avoid:** Since `useWeightUnit()` wraps `useSetting("weightUnit")` which uses React Query with the same query key, invalidation on mutation will trigger re-renders in all subscribed components. This works out of the box.
+**Warning signs:** Temporary inconsistency after changing units -- should resolve within one render cycle.
+
+## Code Examples
+
+### Complete formatWeight Implementation
+
+```typescript
+// src/client/lib/formatters.ts
+export type WeightUnit = "g" | "oz" | "lb" | "kg";
+
+const GRAMS_PER_OZ = 28.3495;
+const GRAMS_PER_LB = 453.592;
+const GRAMS_PER_KG = 1000;
+
+export function formatWeight(
+  grams: number | null | undefined,
+  unit: WeightUnit = "g",
+): string {
+  if (grams == null) return "--";
+
+  switch (unit) {
+    case "g":
+      return `${Math.round(grams)}g`;
+    case "oz":
+      return `${(grams / GRAMS_PER_OZ).toFixed(1)} oz`;
+    case "lb":
+      return `${(grams / GRAMS_PER_LB).toFixed(2)} lb`;
+    case "kg":
+      return `${(grams / GRAMS_PER_KG).toFixed(2)} kg`;
+  }
+}
+```
+
+### useWeightUnit Hook
+
+```typescript
+// src/client/hooks/useWeightUnit.ts
+import { useSetting } from "./useSettings";
+import type { WeightUnit } from "../lib/formatters";
+
+const VALID_UNITS: WeightUnit[] = ["g", "oz", "lb", "kg"];
+
+export function useWeightUnit(): WeightUnit {
+  const { data } = useSetting("weightUnit");
+  if (data && VALID_UNITS.includes(data as WeightUnit)) {
+    return data as WeightUnit;
+  }
+  return "g";
+}
+```
+
+### Component Usage Pattern (e.g., ItemCard)
+
+```typescript
+// Before:
+import { formatWeight } from "../lib/formatters";
+// ...
+{formatWeight(weightGrams)}
+
+// After:
+import { formatWeight } from "../lib/formatters";
+import { useWeightUnit } from "../hooks/useWeightUnit";
+// ...
+const unit = useWeightUnit();
+// ...
+{formatWeight(weightGrams, unit)}
+```
+
+### Stats Prop Pattern (TotalsBar and routes/index.tsx)
+
+When `formatWeight` is called inside a stats array construction (not directly in JSX), the unit must be available in that scope:
+
+```typescript
+// routes/index.tsx - Dashboard
+const unit = useWeightUnit();
+// ...
+stats={[
+  { label: "Items", value: String(global?.itemCount ?? 0) },
+  { label: "Weight", value: formatWeight(global?.totalWeight ?? null, unit) },
+  { label: "Cost", value: formatPrice(global?.totalCost ?? null) },
+]}
+```
+
+## State of the Art
+
+| Old Approach | Current Approach | When Changed | Impact |
+|--------------|------------------|--------------|--------|
+| `Math.round(grams) + "g"` (hardcoded) | `formatWeight(grams, unit)` (parameterized) | This phase | All weight displays become unit-aware |
+
+**Deprecated/outdated:**
+- Nothing to deprecate. The old `formatWeight(grams)` signature remains backward-compatible since `unit` defaults to `"g"`.
+
+## Design Recommendations (Claude's Discretion Areas)
+
+### Unit Selector Placement: TotalsBar
+**Recommendation:** Place the unit toggle in the TotalsBar, right side, near the weight stat. The TotalsBar is visible on every page that shows weight (collection, setups). It is the natural place for a global display preference.
+
+### Pounds Display Format: Decimal
+**Recommendation:** Use decimal pounds (`"2.19 lb"`) rather than traditional `"2 lb 3 oz"`. Reasons: (1) simpler implementation, (2) consistent with how LighterPack handles it, (3) easier to compare weights at a glance, (4) traditional format mixes two units which complicates the mental model.
+
+### Precision Per Unit
+**Recommendation:**
+- `g`: 0 decimal places (integers, matching current behavior)
+- `oz`: 1 decimal place (standard for gear weights -- e.g., "14.2 oz")
+- `lb`: 2 decimal places (e.g., "2.19 lb")
+- `kg`: 2 decimal places (e.g., "1.36 kg")
+
+### Default Unit: Grams
+**Recommendation:** Default to `"g"` -- this preserves backward compatibility. When `useSetting("weightUnit")` returns null (no setting in DB), the app behaves identically to today.
+
+### How formatWeight Gets the Unit: Parameter
+**Recommendation:** Pass `unit` as a parameter rather than using React Context or a global. This keeps `formatWeight` a pure function (testable without React), follows the existing pattern of the codebase (no Context providers used anywhere), and makes the data flow explicit.
+
+## Open Questions
+
+1. **Should the unit toggle appear in setup detail view's sub-bar?**
+   - What we know: Setup detail has its own sticky bar below TotalsBar showing setup-specific stats including weight
+   - What's unclear: Whether the global TotalsBar is visible enough from setup detail view
+   - Recommendation: The TotalsBar is sticky at the top on every page. Its toggle applies globally. No need for a second toggle in the setup bar.

+
+No orphaned requirements. REQUIREMENTS.md marks all three as complete for Phase 7. All three requirement IDs appear in at least one plan's `requirements` field.
+
+### Anti-Patterns Found
+
+| File | Line | Pattern | Severity | Impact |
+|------|------|---------|----------|--------|
+| — | — | None found | — | — |
+
+Scanned all 11 modified files. No TODOs, FIXMEs, placeholder comments, empty implementations, or stub returns found. All `formatWeight` calls outside `formatters.ts` carry the `unit` argument.
+
+### Human Verification Required
+
+#### 1. Unit Toggle Visibility
+
+**Test:** Start `bun run dev:client` and `bun run dev:server`, navigate to http://localhost:5173/collection
+**Expected:** A segmented pill toggle showing g / oz / lb / kg is visible in the sticky top bar, positioned between the GearBox title and the stats (items / total / spent)
+**Why human:** Visual rendering cannot be verified programmatically
+
+#### 2. Unit Toggle Click Behavior
+
+**Test:** With the app running, click "oz" in the toggle on the Collection page
+**Expected:** All weight badges on ItemCards, CategoryHeader totals, and the TotalsBar total update immediately to ounce values (e.g., "15.9 oz"). No page reload required.
+**Why human:** React Query cache invalidation and live re-render require runtime observation
+
+#### 3. Cross-Page Unit Consistency
+
+**Test:** Select "lb" on the Collection page, then navigate to the Dashboard (/), then navigate to a Setup detail page
+**Expected:** The Dashboard Collection card weight shows in lb; all weights in the Setup detail sticky bar and ItemCards show in lb
+**Why human:** Cross-page state propagation via TanStack Router and shared React Query cache requires runtime verification
+
+#### 4. Persistence Across Refresh
+
+**Test:** Select "kg", then hard-refresh the page (Ctrl+R or F5)
+**Expected:** After refresh, all weights still display in kg. The kg button appears active/highlighted in the toggle.
+**Why human:** Browser session handling and settings API round-trip require runtime verification
+
+### Gaps Summary
+
+No automated gaps found. All artifacts exist, are substantive, and are correctly wired. The 3 human verification items are standard runtime behaviors (visual rendering, live updates, persistence) that cannot be verified statically.
+
+The implementation is complete and correct based on static analysis:
+- `formatWeight` conversion math is verified by 21 passing tests
+- All 8 component call sites pass `unit` from `useWeightUnit()` — confirmed by exhaustive grep
+- TotalsBar contains the full toggle UI with `useUpdateSetting` wired to `weightUnit` key
+- `useWeightUnit` correctly wraps `useSetting("weightUnit")` with type validation and "g" default
+- Full test suite (108 tests) passes with no regressions
+- Lint clean (78 files, no issues)
+- All 4 phase commits verified in git history (431c179, 6cac0a3, ada3791, faa4378)

+Add candidate status tracking (researching/ordered/arrived) as a full vertical slice: schema migration, service/Zod updates, tests, and clickable status badge UI on CandidateCard.
+
+Purpose: Let users track purchase progress for candidates they are evaluating in planning threads.
+Output: Working status badge on each candidate card with popup menu to change status.

+    1. **Schema migration** -- Add status column to `threadCandidates` in `src/db/schema.ts`:
+       ```typescript
+       status: text("status").notNull().default("researching"),
+       ```
+       Then run `bun run db:generate && bun run db:push` to apply.
+

+       ```typescript
+       export const candidateStatusSchema = z.enum(["researching", "ordered", "arrived"]);
+       ```
+       Add `status: candidateStatusSchema.optional()` to `createCandidateSchema`. Since `updateCandidateSchema = createCandidateSchema.partial()`, it automatically includes status as optional.
+
+    3. **Service updates** -- In `src/server/services/thread.service.ts`:
+       - In `getThreadWithCandidates`, add `status: threadCandidates.status` to the select object (between `imageFilename` and `createdAt`).
+       - In `createCandidate`, add `status: data.status ?? "researching"` to the values object.
+       - In `updateCandidate`, add `status` to the data type: `status: "researching" | "ordered" | "arrived"`.
+
+    4. **Client type updates** -- In `src/client/hooks/useThreads.ts`, add `status: "researching" | "ordered" | "arrived"` to `CandidateWithCategory` interface. In `src/client/hooks/useCandidates.ts`, add `status?: "researching" | "ordered" | "arrived"` to `CandidateResponse` interface.
+
+    5. **Test helper** -- In `tests/helpers/db.ts`, add `status TEXT NOT NULL DEFAULT 'researching'` to the `thread_candidates` CREATE TABLE statement (after `image_filename TEXT` line).
+
+    6. **Service tests** -- In `tests/services/thread.service.test.ts`, add a describe block "candidate status" with the tests from the behavior section above.

+       - Props: `status: "researching" | "ordered" | "arrived"`, `onStatusChange: (status: "researching" | "ordered" | "arrived") => void`
+       - Status config map:

+           researching: { icon: "search", label: "Researching" },
+           ordered: { icon: "truck", label: "Ordered" },

+         } as const;
+         ```
+       - Render as a pill button (muted gray tones per user decision -- NOT semantic colors):
+         - Use `bg-gray-100 text-gray-600` styling, similar neutral tone to the category pill
+         - Show `LucideIcon` (size 14) + text label
+       - On click: call `e.stopPropagation()` (prevent card click propagation per pitfall #3), toggle popup menu open/closed
+       - Popup menu: `position: absolute` below the badge, `right-0`, with 3 options (each showing icon + label). Use a `containerRef` + `useEffect` mousedown listener for click-outside dismiss (same pattern as `CategoryPicker`). Pressing Escape also closes the menu.
+       - When an option is clicked: call `onStatusChange(selectedStatus)`, close the menu.
+       - Show a subtle checkmark or different background on the currently active status in the menu.
+

+       - Import `StatusBadge` from `./StatusBadge`.
+       - Add `<StatusBadge status={status} onStatusChange={onStatusChange} />` to the pill row (the `flex flex-wrap gap-1.5 mb-3` div), after the category pill.
+
+    3. **Update thread detail page caller** -- Find where `CandidateCard` is rendered (in the thread detail route). Add the `status` and `onStatusChange` props.

+    Create `src/client/components/CategoryFilterDropdown.tsx` -- a searchable dropdown showing categories with Lucide icons. This is a FILTER dropdown, NOT the form-based `CategoryPicker` (which handles creation). Keep them separate per user decision.
+
+    **Props:**
+    ```typescript
+    interface CategoryFilterDropdownProps {
+      value: number | null;           // selected category ID, null = "All categories"
+      onChange: (value: number | null) => void;
+      categories: Array<{ id: number; name: string; icon: string }>;
+    }
+    ```
+
+    **Structure:**
+    - **Trigger button**: Shows "All categories" with a chevron-down icon when `value` is null. Shows the selected category's `LucideIcon` (size 14) + name when a category is selected. Style: `px-3 py-2 border border-gray-200 rounded-lg text-sm bg-white` (matching search input height). Include a small clear "x" button on the right when a category is selected (clicking it calls `onChange(null)` without opening the dropdown).
+    - **Dropdown panel**: Opens below the trigger, `position: absolute`, `z-20`, white bg, border, rounded-lg, shadow-lg, max-height with overflow-y-auto. Width matches trigger or has a reasonable min-width (~220px).
+    - **Search input inside dropdown**: Text input at top of dropdown, placeholder "Search categories...", filters the category list as user types. Auto-focused when dropdown opens.
+    - **Option list**: "All categories" as first option (selecting calls `onChange(null)` and closes). Then each category: `LucideIcon` (size 16) + category name. Highlight the currently selected option with a subtle bg color. Hover state on each option.
+    - **Click-outside dismiss**: Use `containerRef` + `useEffect` mousedown listener pattern (same as `CategoryPicker`). Also close on Escape keydown.
+    - **State reset**: Clear internal search text when dropdown closes.
+
+    **Do NOT:**
+    - Reuse or modify `CategoryPicker.tsx`
+    - Add category creation capability

+       }, [items, searchText, categoryFilter]);
+       ```
+       Import `useMemo` from React, import `useCategories` from hooks.
+
+    4. Compute filter state:
+       ```typescript
+       const hasActiveFilters = searchText !== "" || categoryFilter !== null;
+       ```
+
+    5. Add sticky toolbar ABOVE the existing item grid rendering (after loading/empty checks, before the grouped items). The toolbar only shows when there are items:
+       ```jsx
+       <div className="sticky top-0 z-10 bg-white/95 backdrop-blur-sm border-b border-gray-100 -mx-4 px-4 py-3 sm:-mx-6 sm:px-6 lg:-mx-8 lg:px-8 mb-6">
+         <div className="flex gap-3 items-center">
+           <div className="relative flex-1">
+             <input
+               type="text"
+               placeholder="Search items..."
+               value={searchText}
+               onChange={(e) => setSearchText(e.target.value)}
+               className="w-full px-3 py-2 border border-gray-200 rounded-lg text-sm focus:outline-none focus:ring-2 focus:ring-gray-400 focus:border-transparent"
+             />
+             {searchText && (
+               <button onClick={() => setSearchText("")} className="absolute right-2 top-1/2 -translate-y-1/2 text-gray-400 hover:text-gray-600">
+                 {/* small x icon */}
+               </button>
+             )}
+           </div>
+           <CategoryFilterDropdown
+             value={categoryFilter}
+             onChange={setCategoryFilter}
+             categories={categories ?? []}
+           />
+         </div>
+         {hasActiveFilters && (
+           <p className="text-xs text-gray-500 mt-2">
+             Showing {filteredItems.length} of {items?.length ?? 0} items
+           </p>
+         )}
+       </div>
+       ```
+
+    6. Conditional rendering based on filter state:
+       - **When `hasActiveFilters` is true**: Render `filteredItems` as a flat grid (no category grouping, no `CategoryHeader`). If `filteredItems.length === 0`, show "No items match your search" centered text message.
+       - **When `hasActiveFilters` is false**: Keep existing category-grouped rendering exactly as-is (the `groupedItems` Map pattern), but use `filteredItems` as the source (which equals all items when no filters).
+
+    **PlanningView changes:**
+
+    1. Import `CategoryFilterDropdown` from `../../components/CategoryFilterDropdown`.
+    2. Replace the native `<select>` element (lines ~277-291) with:
+       ```jsx
+       <CategoryFilterDropdown
+         value={categoryFilter}
+         onChange={setCategoryFilter}
+         categories={categories ?? []}
+       />
+       ```
+    3. Remove the `useCategories` hook call if it's already called earlier, or keep it -- just make sure categories data is available.
+
+    **Important per user decisions:**
+    - Search matches item names ONLY (not category names) -- the dropdown handles category filtering
+    - No debounce on search input (per CONTEXT.md, <1000 items)
+    - No combined "clear all" button -- user clears search and dropdown individually
+    - Filters naturally reset on tab switch because `CollectionView` unmounts when tab changes (conditional rendering in `CollectionPage`). Verify this is the case -- if `CollectionView` stays mounted, add a `key={tab}` prop to force remount.

+# Phase 8: Search, Filter, and Candidate Status - Context
+
+**Gathered:** 2026-03-16
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+Users can find collection items quickly via text search and category filter, track candidate purchase progress with status badges, and use an icon-aware category dropdown on both gear and planning tabs. Side-by-side comparison, ranking, and impact preview are separate phases.
+
+</domain>
+
+<decisions>
+## Implementation Decisions
+
+### Search & filter bar
+- Sticky toolbar above the item grid on the gear tab, stays visible on scroll
+- Search input + category dropdown side by side in the toolbar
+- Client-side filtering on every keystroke (no debounce needed for <1000 items)
+- Search matches item names only (not category names) — category filtering is the dropdown's job
+- When any filter is active, items display as a flat grid (no category group headers)
+- Filters reset when switching between gear/planning/setups tabs
+
+### Candidate status
+- Three statuses: researching (default), ordered, arrived
+- Status badge appears in the existing pill row alongside weight/price/category pills
+- Badge shows icon + text label (e.g., magnifying glass + "researching", truck + "ordered", check + "arrived")
+- Muted/neutral color scheme for status badges — gray tones, not semantic colors. Color reserved for weight/price pills
+- Click the status badge to open a small popup menu showing all three status options (allows jumping to any status, including backward)
+- New candidates default to "researching" status
+- Requires `status` column on `thread_candidates` table (schema migration)
+
+### Filter feedback
+- "Showing X of Y items" count displayed when filters are active — placement at Claude's discretion
+- No combined "clear all" button — user clears search text and resets category dropdown individually
+- "No items match your search" simple text message for empty filter results (no suggestions)
+
+### Icon-aware category dropdown
+- Shared `CategoryFilterDropdown` component used on both gear tab and planning tab
+- Separate from the existing `CategoryPicker` component (which is a form combobox for category selection/creation)
+- "All categories" as the first option — selecting it clears the category filter
+- Searchable dropdown — includes a search input inside the dropdown for filtering categories
+- Trigger button shows the selected category's Lucide icon + name when a category is selected
+
+### Claude's Discretion
+- Exact toolbar styling (padding, borders, background)
+- Filter result count placement (in toolbar or above grid)
+- Status popup menu implementation details
+- Specific gray tone values for status badges
+- Keyboard accessibility patterns for the dropdown and status menu
+- Icon choices for status badges (magnifying glass, truck, check are suggestions)
+
+</decisions>
+
+<code_context>
+## Existing Code Insights
+
+### Reusable Assets
+- `CategoryPicker` (`src/client/components/CategoryPicker.tsx`): Combobox with icon display, search, keyboard nav, and category creation. Pattern reference for the new filter dropdown, but not reusable directly since it's a form input, not a filter
+- `LucideIcon` (`src/client/lib/iconData.ts`): Dynamic icon renderer used throughout the app — reuse for dropdown icons and status badges
+- `useCategories` hook: Already fetches all categories with icons — drives the dropdown options
+- `useItems` hook: Returns all items — client-side filtering can operate on this data
+- `CollectionTabs` / `ThreadTabs`: Tab component with pill styling — existing navigation pattern
+- `CandidateCard`: Currently has weight/price/category pill row — status badge slots in here
+
+### Established Patterns
+- Client-side state for filter/tab state (`useState` in route components, not Zustand)
+- URL params for tab navigation (`?tab=gear`)
+- React Query for server data, Zustand for UI state (panels/dialogs only)
+- Pill badges: blue-50/blue-400 for weight, green-50/green-500 for price, gray-50/gray-600 for category
+
+### Integration Points
+- `CollectionView` function in `src/client/routes/collection/index.tsx`: Search/filter toolbar goes here, above the category-grouped items
+- `PlanningView` function: Replace existing `<select>` category filter with shared `CategoryFilterDropdown`
+- `CandidateCard`: Add status prop and badge to the pill row
+- `thread_candidates` table in `src/db/schema.ts`: Add `status` column with default "researching"
+- Candidate API routes + services: Need to handle status field in CRUD operations

+# Phase 8: Search, Filter, and Candidate Status - Research
+
+**Researched:** 2026-03-16
+**Domain:** Client-side filtering, searchable dropdown components, schema migration, status badges
+**Confidence:** HIGH
+
+## Summary
+
+Phase 8 adds three capabilities to GearBox: (1) a search and category filter toolbar on the gear tab with result counts, (2) an icon-aware searchable category filter dropdown shared between gear and planning tabs, and (3) candidate status tracking (researching/ordered/arrived) with clickable status badges. The work spans all layers: schema migration (adding `status` column to `thread_candidates`), service/route updates (CRUD for status field), Zod schema updates, and several new client components.
+
+The codebase is well-structured for these additions. Client-side filtering is straightforward since `useItems()` already returns all items with category info. The `CategoryPicker` component provides a reference pattern for the searchable dropdown, though the new `CategoryFilterDropdown` is simpler (no creation flow). The candidate status feature requires a schema migration, but Drizzle Kit and the existing migration infrastructure handle this cleanly.
+
+**Primary recommendation:** Build in two waves -- (1) backend schema migration + candidate status (smaller, foundational), then (2) search/filter toolbar and shared category dropdown (larger, UI-focused). Both waves are pure client-side filtering with minimal server changes.

+## Phase Requirements
+
+| ID | Description | Research Support |
+|----|-------------|-----------------|
+| SRCH-01 | User can search items by name with instant filtering as they type | Client-side `useState` + `.filter()` on `useItems()` data. Pattern documented in Architecture section |
+| SRCH-02 | User can filter collection items by category via dropdown | New `CategoryFilterDropdown` component using `useCategories()` data. Pattern from existing `CategoryPicker` |
+| SRCH-03 | User can combine text search with category filter simultaneously | Chain `.filter()` calls -- search text AND category ID. Both stored as `useState` in `CollectionView` |
+| SRCH-04 | User can see result count when filters are active | Computed from `filteredItems.length` vs `items.length`. Conditional rendering when filters active |
+| SRCH-05 | User can clear all active filters with one action | Per CONTEXT.md: no combined button. User clears search text and resets dropdown individually. Both inputs have clear affordances |
+| PLAN-01 | Planning category filter dropdown shows Lucide icons alongside names | Replace existing `<select>` in `PlanningView` with shared `CategoryFilterDropdown` |
+| CAND-01 | Each candidate displays a status badge (researching, ordered, or arrived) | Add `status` prop to `CandidateCard`, render as pill in existing flex row |
+| CAND-02 | User can change a candidate's status via click interaction | Status badge click opens popup menu. Uses `useUpdateCandidate` mutation with `status` field |
+| CAND-03 | New candidates default to "researching" status | Schema default + Drizzle `.default("researching")`. Service layer already handles defaults via `?? null` pattern |

+  services/
+    thread.service.test.ts          # MODIFIED - add tests for status field
+```
+
+### Pattern 1: Client-Side Filtering with useState
+**What:** Filter items in-memory using React state, no server round-trips
+**When to use:** Small datasets (<1000 items), instant feedback needed
+**Example:**
+```typescript
+// In CollectionView
+function CollectionView() {
+  const [searchText, setSearchText] = useState("");
+  const [categoryFilter, setCategoryFilter] = useState<number | null>(null);
+  const { data: items } = useItems();
+
+  const filteredItems = useMemo(() => {
+    if (!items) return [];
+    return items.filter((item) => {
+      const matchesSearch = searchText === "" ||
+        item.name.toLowerCase().includes(searchText.toLowerCase());
+      const matchesCategory = categoryFilter === null ||
+        item.categoryId === categoryFilter;
+      return matchesSearch && matchesCategory;
+    });
+  }, [items, searchText, categoryFilter]);
+
+  const hasActiveFilters = searchText !== "" || categoryFilter !== null;
+  // ...
+}
+```
+
+### Pattern 2: Searchable Dropdown with Click-Outside Dismiss
+**What:** Dropdown with internal search input, opens on click, closes on click-outside or Escape
+**When to use:** Category filter dropdowns where a native `<select>` is insufficient (need icons, search)
+**Example:**
+```typescript
+// Reference: existing CategoryPicker pattern (containerRef + useEffect for mousedown)
+function CategoryFilterDropdown({ value, onChange, categories }) {
+  const [isOpen, setIsOpen] = useState(false);
+  const [search, setSearch] = useState("");
+  const containerRef = useRef<HTMLDivElement>(null);
+
+  useEffect(() => {
+    function handleClickOutside(e: MouseEvent) {
+      if (containerRef.current && !containerRef.current.contains(e.target as Node)) {
+        setIsOpen(false);
+        setSearch("");
+      }
+    }
+    document.addEventListener("mousedown", handleClickOutside);
+    return () => document.removeEventListener("mousedown", handleClickOutside);
+  }, []);
+  // ... trigger button + dropdown list with LucideIcon per option
+}
+```
+
+### Pattern 3: Status Badge with Popup Menu
+**What:** Clickable pill badge that opens a small menu to change status
+**When to use:** Inline status changes without opening a modal/panel
+**Example:**
+```typescript
+// StatusBadge - renders in CandidateCard's pill row
+function StatusBadge({ status, onStatusChange }: {
+  status: "researching" | "ordered" | "arrived";
+  onStatusChange: (status: string) => void;
+}) {
+  const [menuOpen, setMenuOpen] = useState(false);
+  const containerRef = useRef<HTMLDivElement>(null);
+  // Click-outside dismiss pattern (same as CategoryPicker)
+  // Renders: pill button + absolute-positioned menu with 3 options
+}
+```
+
+### Pattern 4: Schema Migration with Default Value
+**What:** Add column with default to existing table using Drizzle Kit
+**When to use:** Adding new fields that need backward compatibility with existing rows
+**Example:**
+```typescript
+// In src/db/schema.ts -- add to threadCandidates table definition:
+status: text("status").notNull().default("researching"),
+
+// Then run: bun run db:generate && bun run db:push
+// Drizzle Kit will generate: ALTER TABLE thread_candidates ADD COLUMN status TEXT NOT NULL DEFAULT 'researching'
+```
+
+### Pattern 5: Flat Grid vs Category-Grouped Grid
+**What:** Conditionally render items as flat grid or category-grouped sections
+**When to use:** When filters are active, category grouping loses meaning
+**Example:**
+```typescript
+// When filters active: flat grid of filteredItems
+// When no filters: existing category-grouped Map pattern (already in CollectionView)
+const hasActiveFilters = searchText !== "" || categoryFilter !== null;
+
+return hasActiveFilters ? (
+  <div className="grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3 gap-4">
+    {filteredItems.map((item) => <ItemCard key={item.id} ... />)}
+  </div>
+) : (
+  // Existing grouped rendering with CategoryHeader
+  <>
+    {Array.from(groupedItems.entries()).map(([categoryId, { items, ... }]) => (
+      // ... existing CategoryHeader + grid pattern
+    ))}
+  </>
+);
+```
+
+### Anti-Patterns to Avoid
+- **Server-side filtering for this use case:** Out of scope per REQUIREMENTS.md ("Premature for single-user app with <1000 items"). All filtering is client-side.
+- **Zustand for filter state:** Per codebase convention, filter/tab state uses `useState` in route components, not Zustand. Zustand is only for panel/dialog state.
+- **Debouncing search input:** Per CONTEXT.md, no debounce needed for <1000 items. React is fast enough for synchronous filtering.
+- **Modifying CategoryPicker:** The new dropdown is separate from `CategoryPicker`. CategoryPicker is a form combobox for category selection/creation. Do not conflate them.
+
+## Don't Hand-Roll
+
+| Problem | Don't Build | Use Instead | Why |
+|---------|-------------|-------------|-----|
+| Click-outside detection | Custom event system | `useEffect` + `mousedown` listener on `document` (existing pattern from `CategoryPicker`) | Pattern already proven in codebase, handles edge cases |
+| Dynamic icon rendering | SVG string lookup | `LucideIcon` component from `src/client/lib/iconData.tsx` | Already handles kebab-case to PascalCase conversion, fallback to Package icon |
+| Schema migrations | Manual SQL | `bun run db:generate` + `bun run db:push` (Drizzle Kit) | Generates correct ALTER TABLE, manages migration journal |
+| Popup menu positioning | Complex position calculation | CSS `position: absolute` + `right-0` on container with `position: relative` | Simple case -- badge is in a flex row, menu drops below. No viewport collision for this layout |
+
+## Common Pitfalls
+
+### Pitfall 1: Forgetting to Update Test Helper DB Schema
+**What goes wrong:** Adding `status` column to `src/db/schema.ts` but not to `tests/helpers/db.ts` CREATE TABLE statement causes all thread service tests to fail.
+**Why it happens:** The test helper creates in-memory SQLite tables manually, not via Drizzle migrations.
+**How to avoid:** Always update both `src/db/schema.ts` AND `tests/helpers/db.ts` thread_candidates CREATE TABLE in the same commit.
+**Warning signs:** Tests that worked before now fail with "table thread_candidates has no column named status".
+
+### Pitfall 2: Filter State Not Resetting on Tab Switch
+**What goes wrong:** User searches on gear tab, switches to planning, comes back -- old search text still showing stale filtered results.
+**Why it happens:** useState persists while the component is mounted. Tab switching in `CollectionPage` conditionally renders views but `CollectionView` may stay mounted if React reuses the component.
+**How to avoid:** Use a `key` prop tied to the tab value on the view components, or explicitly reset filter state in a `useEffect` keyed on tab changes. The simplest approach: since `CollectionView` is conditionally rendered (unmounted when tab !== "gear"), useState will naturally reset. Verify this is the case.
+**Warning signs:** Filters persisting when switching tabs.
+
+### Pitfall 3: Status Badge Click Propagating to Card Actions
+**What goes wrong:** Clicking the status badge also triggers the card's edit panel or other click handlers.
+**Why it happens:** Event bubbling -- `CandidateCard` has click handlers on parent elements.
+**How to avoid:** Call `e.stopPropagation()` on the status badge click handler. The existing code already does this for the external link button.
+**Warning signs:** Clicking status badge opens the edit panel instead of the status menu.
+
+### Pitfall 4: Candidate Status Not Included in API Responses
+**What goes wrong:** Status column is added to schema but `getThreadWithCandidates` doesn't select it, so frontend never receives it.
+**Why it happens:** The service uses explicit `select()` clauses, not `select(*)`. New columns must be explicitly added.
+**How to avoid:** Add `status: threadCandidates.status` to the select object in `getThreadWithCandidates`.
+**Warning signs:** Status badge always shows "researching" even after changing it.
+
+### Pitfall 5: Zod Schema Missing Status in updateCandidateSchema
+**What goes wrong:** PUT request to update candidate status gets rejected by Zod validation.
+**Why it happens:** `updateCandidateSchema = createCandidateSchema.partial()` -- if `createCandidateSchema` doesn't include status, neither does update.
+**How to avoid:** Add `status` to `updateCandidateSchema` (and optionally `createCandidateSchema`). Use `z.enum(["researching", "ordered", "arrived"])`.
+**Warning signs:** 400 errors when trying to change status via the badge.
+
+### Pitfall 6: Sticky Toolbar Covering Content
+**What goes wrong:** The sticky search/filter toolbar overlaps the first row of items when scrolled.
+**Why it happens:** `position: sticky` without adequate spacing pushes content under the toolbar.
+**How to avoid:** Ensure the grid content below the toolbar has no negative margin or overlapping. The toolbar sits in normal flow and sticks on scroll -- padding/margin on the toolbar itself handles spacing.
+**Warning signs:** First item card partially hidden behind the toolbar when scrolling.
+
+## Code Examples
+
+### Schema Migration: Add Status Column
+```typescript
+// src/db/schema.ts -- threadCandidates table
+export const threadCandidates = sqliteTable("thread_candidates", {
+  // ... existing columns ...
+  status: text("status").notNull().default("researching"),
+});
+```
+
+### Zod Schema Update
+```typescript
+// src/shared/schemas.ts
+export const candidateStatusSchema = z.enum(["researching", "ordered", "arrived"]);
+
+export const createCandidateSchema = z.object({
+  name: z.string().min(1, "Name is required"),
+  weightGrams: z.number().nonnegative().optional(),
+  priceCents: z.number().int().nonnegative().optional(),
+  categoryId: z.number().int().positive(),
+  notes: z.string().optional(),
+  productUrl: z.string().url().optional().or(z.literal("")),
+  imageFilename: z.string().optional(),
+  status: candidateStatusSchema.optional(), // optional on create, defaults to "researching"
+});
+
+export const updateCandidateSchema = createCandidateSchema.partial();
+// This automatically includes status as optional
+```
+
+### Service Update: Status in getThreadWithCandidates
+```typescript
+// src/server/services/thread.service.ts -- in getThreadWithCandidates
+const candidateList = db
+  .select({
+    id: threadCandidates.id,
+    threadId: threadCandidates.threadId,
+    name: threadCandidates.name,
+    weightGrams: threadCandidates.weightGrams,
+    priceCents: threadCandidates.priceCents,
+    categoryId: threadCandidates.categoryId,
+    notes: threadCandidates.notes,
+    productUrl: threadCandidates.productUrl,
+    imageFilename: threadCandidates.imageFilename,
+    status: threadCandidates.status,  // ADD THIS
+    createdAt: threadCandidates.createdAt,
+    updatedAt: threadCandidates.updatedAt,
+    categoryName: categories.name,
+    categoryIcon: categories.icon,
+  })
+  .from(threadCandidates)
+  .innerJoin(categories, eq(threadCandidates.categoryId, categories.id))
+  .where(eq(threadCandidates.threadId, threadId))
+  .all();
+```
+
+### Test Helper Update
+```sql
+-- tests/helpers/db.ts -- thread_candidates CREATE TABLE
+CREATE TABLE thread_candidates (
+  id INTEGER PRIMARY KEY AUTOINCREMENT,
+  thread_id INTEGER NOT NULL REFERENCES threads(id) ON DELETE CASCADE,
+  name TEXT NOT NULL,
+  weight_grams REAL,
+  price_cents INTEGER,
+  category_id INTEGER NOT NULL REFERENCES categories(id),
+  notes TEXT,
+  product_url TEXT,
+  image_filename TEXT,
+  status TEXT NOT NULL DEFAULT 'researching',
+  created_at INTEGER NOT NULL DEFAULT (unixepoch()),
+  updated_at INTEGER NOT NULL DEFAULT (unixepoch())
+)
+```
+
+### Client Hook Update: CandidateWithCategory Type
+```typescript
+// src/client/hooks/useThreads.ts -- add status to CandidateWithCategory
+interface CandidateWithCategory {
+  id: number;
+  threadId: number;
+  name: string;
+  weightGrams: number | null;
+  priceCents: number | null;
+  categoryId: number;
+  notes: string | null;
+  productUrl: string | null;
+  imageFilename: string | null;
+  status: "researching" | "ordered" | "arrived";  // ADD THIS
+  createdAt: string;
+  updatedAt: string;
+  categoryName: string;
+  categoryIcon: string;
+}
+```
+
+### Lucide Icon Names for Status Badges
+```typescript
+// Available in lucide-react (verified via iconData.tsx icon groups)
+const STATUS_CONFIG = {
+  researching: { icon: "search", label: "Researching" },
+  ordered: { icon: "truck", label: "Ordered" },
+  arrived: { icon: "check", label: "Arrived" },
+} as const;
+// Note: "search" maps to lucide's Search icon (magnifying glass)
+// "truck" maps to Truck icon
+// "check" maps to Check icon
+// All are valid lucide-react icon names and work with the LucideIcon component
+```
+
+### Sticky Toolbar Pattern
+```typescript
+// Toolbar sticks to top on scroll
+<div className="sticky top-0 z-10 bg-white/95 backdrop-blur-sm border-b border-gray-100 -mx-4 px-4 py-3 sm:-mx-6 sm:px-6 lg:-mx-8 lg:px-8">
+  <div className="flex gap-3 items-center">
+    <input
+      type="text"
+      placeholder="Search items..."
+      value={searchText}
+      onChange={(e) => setSearchText(e.target.value)}
+      className="flex-1 px-3 py-2 border border-gray-200 rounded-lg text-sm ..."
+    />
+    <CategoryFilterDropdown
+      value={categoryFilter}
+      onChange={setCategoryFilter}
+    />
+  </div>
+</div>
+```
+
+## State of the Art
+
+| Old Approach | Current Approach | When Changed | Impact |
+|--------------|------------------|--------------|--------|
+| Native `<select>` for category filter | Searchable dropdown with icons | This phase | Planning view's `<select>` replaced with `CategoryFilterDropdown` |
+| No candidate status tracking | `status` column with badge UI | This phase | Candidates now track purchase progress |
+| Category-grouped items only | Conditional flat grid when filtering | This phase | Better UX when searching/filtering |
+
+## Open Questions
+
+1. **Sticky toolbar `top` offset**
+   - What we know: The toolbar should be `sticky top-0` but needs to account for any fixed header/navbar if one exists.
+   - What's unclear: Whether there's a fixed navbar above the collection page that would require a `top-[Npx]` offset instead of `top-0`.
+   - Recommendation: Start with `top-0`. If there's a fixed navbar, adjust the top value to match its height. The current layout appears to not have a fixed navbar based on the route structure.
+
+2. **useCandidates hook status mutation**
+   - What we know: `useUpdateCandidate` already exists and can be used for status changes via `apiPut`.
+   - What's unclear: Whether a dedicated `useUpdateCandidateStatus` hook is cleaner than reusing the general `useUpdateCandidate`.
+   - Recommendation: Reuse `useUpdateCandidate` -- it already accepts partial updates. Adding a dedicated hook would be unnecessary abstraction.

+### Sampling Rate
+- **Per task commit:** `bun test tests/services/thread.service.test.ts`
+- **Per wave merge:** `bun test`
+- **Phase gate:** Full suite green before `/gsd:verify-work`
+
+### Wave 0 Gaps
+- [ ] `tests/helpers/db.ts` -- add `status TEXT NOT NULL DEFAULT 'researching'` to thread_candidates CREATE TABLE
+- [ ] `tests/services/thread.service.test.ts` -- add tests for: (1) createCandidate returns status "researching" by default, (2) updateCandidate can change status, (3) getThreadWithCandidates includes status field
+
+## Sources
+
+### Primary (HIGH confidence)
+- **Codebase analysis** -- direct reading of all relevant source files:
+  - `src/db/schema.ts` -- current threadCandidates table definition (no status column)
+  - `src/client/routes/collection/index.tsx` -- CollectionView (where toolbar goes) and PlanningView (where `<select>` is replaced)
+  - `src/client/components/CandidateCard.tsx` -- current pill row layout (where status badge goes)
+  - `src/client/components/CategoryPicker.tsx` -- searchable dropdown reference pattern
+  - `src/client/lib/iconData.tsx` -- LucideIcon component and available icon names
+  - `src/server/services/thread.service.ts` -- candidate CRUD with explicit select fields
+  - `src/shared/schemas.ts` -- Zod validation schemas for candidates
+  - `src/client/hooks/useThreads.ts` -- CandidateWithCategory interface
+  - `src/client/hooks/useCandidates.ts` -- mutation hooks for candidates
+  - `tests/helpers/db.ts` -- test helper CREATE TABLE statements
+  - `drizzle.config.ts` -- migration config
+  - `drizzle/0001_rename_emoji_to_icon.sql` -- migration precedent
+
+### Secondary (MEDIUM confidence)
+- **Drizzle ORM** -- ALTER TABLE ADD COLUMN with DEFAULT for SQLite is well-documented and standard
+
+### Tertiary (LOW confidence)
+- None -- all findings are from direct codebase analysis
+
+## Metadata
+
+**Confidence breakdown:**
+- Standard stack: HIGH -- no new libraries, all existing
+- Architecture: HIGH -- patterns derived from existing codebase conventions
+- Pitfalls: HIGH -- identified from actual code reading (explicit selects, test helper, event bubbling)
+- Schema migration: HIGH -- follows existing migration pattern (drizzle/0001_rename_emoji_to_icon.sql)

+## Goal Achievement
+
+### Observable Truths
+
+| # | Truth | Status | Evidence |
+|---|-------|--------|---------|
+| 1 | Each candidate displays a status badge showing one of three statuses: researching, ordered, or arrived | VERIFIED | `StatusBadge.tsx` renders pill with `STATUS_CONFIG` map; `CandidateCard.tsx` line 114 renders `<StatusBadge status={status} .../>` |
+| 2 | User can click a status badge to open a popup menu and change the candidate's status to any of the three options | VERIFIED | `StatusBadge.tsx`: click handler calls `setIsOpen`, popup renders all 3 options, each calls `onStatusChange(key)` and closes |
+| 3 | New candidates automatically have status 'researching' without the user needing to set it | VERIFIED | `schema.ts` line 61: `.default("researching")`; `thread.service.ts` line 153: `status: data.status ?? "researching"` |
+| 4 | User can type in a search field on the gear tab and see items filtered instantly by name as they type | VERIFIED | `collection/index.tsx` lines 58-73: `useState searchText`, `useMemo filteredItems` filters by `item.name.toLowerCase().includes(...)` on every change |
+| 5 | User can select a category from a searchable dropdown (with Lucide icons) to filter items on both gear and planning tabs | VERIFIED | `CategoryFilterDropdown.tsx` renders `LucideIcon` per option; used in both `CollectionView` (line 205) and `PlanningView` (line 373) |
+| 6 | User can combine text search with category filter to narrow results | VERIFIED | `useMemo filteredItems` (lines 61-71): both `matchesSearch` AND `matchesCategory` must be true |
+| 7 | User sees 'Showing X of Y items' when filters are active on the gear tab | VERIFIED | `collection/index.tsx` lines 211-215: `{hasActiveFilters && <p>Showing {filteredItems.length} of {items.length} items</p>}` |
+| 8 | User can clear search text and reset category filter individually | VERIFIED | Search: clear button at line 184 calls `setSearchText("")`; Category: `x` button in `CategoryFilterDropdown.tsx` line 91 calls `onChange(null)` |
+| 9 | When filters are active, items display as a flat grid without category group headers | VERIFIED | Lines 219-278: `hasActiveFilters` branches to flat `<div className="grid ...">` rendering `filteredItems` directly, bypassing `groupedItems` Map |
+| 10 | Empty filter results show 'No items match your search' message | VERIFIED | Lines 220-226: `filteredItems.length === 0` shows `<p>No items match your search</p>` |
+| 11 | Planning tab category filter shows Lucide icons alongside category names | VERIFIED | `PlanningView` at line 373 uses `<CategoryFilterDropdown>` which renders `LucideIcon` per category option |

+
+### Anti-Patterns Found
+
+| File | Line | Pattern | Severity | Impact |
+|------|------|---------|----------|--------|
+| `src/client/routes/collection/index.tsx` | 222-224 | Biome formatter disagreement (JSX whitespace in `<p>` tag) | Info | Formatter-only issue, no logic impact. Not a code defect. |
+| `.planning/config.json` | all | Biome formatter expects tabs | Info | Planning config, no source code impact |
+| `drizzle/meta/0002_snapshot.json` | all | Biome formatter expects tabs | Info | Generated drizzle file, no source code impact |
+
+No blockers. No logic anti-patterns in source files. All stub detection checks pass — no `return null`, `return {}`, `return []`, console-only implementations, or placeholder comments found in any phase artifact.
+
+### Human Verification Required
+
+#### 1. StatusBadge Popup Behavior
+
+**Test:** Navigate to a thread detail page, click the "Researching" badge on any candidate
+**Expected:** Popup menu appears below the badge showing three options (Researching with search icon, Ordered with truck icon, Arrived with check icon). Currently active status is highlighted. Clicking outside or pressing Escape closes without changes.
+**Why human:** Popup positioning, z-index rendering, and dismiss behavior require browser interaction
+
+#### 2. Sticky Toolbar on Scroll
+
+**Test:** On the gear tab with 10+ items, scroll down the page
+**Expected:** The search input and category dropdown remain fixed at the top of the viewport while items scroll beneath
+**Why human:** CSS `sticky` positioning behavior with `backdrop-blur-sm` requires visual confirmation
+
+#### 3. Filter Reset on Tab Switch
+
+**Test:** Enter search text "tent", select a category, then switch to the Planning tab, then switch back to Gear
+**Expected:** On return to Gear tab, search field is empty and "All categories" is shown (no filter active)
+**Why human:** Requires verifying React component unmount/remount behavior through actual navigation
+
+### Gaps Summary
+
+No gaps. All 11 observable truths are verified. All 8 artifacts exist with substantive implementations. All 7 key links are confirmed wired. All 9 requirements are satisfied. 24 tests pass including 5 new candidate status tests. 113 total tests pass across the full suite.
+
+The only open items are 3 human verification checks for visual/behavioral aspects that cannot be confirmed statically — these are normal for a UI phase and do not indicate missing functionality.
+
+**Note on SRCH-05:** The requirement states "clear all active filters with one action." The implementation provides individual clear controls (search `x` button and dropdown `x` button) per explicit design decision documented in `08-CONTEXT.md`. The REQUIREMENTS.md marks SRCH-05 as [x] complete. This is an intentional scoping decision made during context capture, not a missed requirement.

+
+<objective>
+Add per-setup item classification (base weight / worn / consumable) as a complete vertical slice: schema migration, service layer with tests, API route, and ClassificationBadge UI component wired into the setup detail page.
+
+Purpose: Users need to classify gear items by their role within a specific setup to enable weight breakdown analysis. The same item can serve different roles in different setups (e.g., a jacket is "worn" in a hiking setup but "base weight" in a bike setup).
+
+Output: Working classification system -- clicking a badge on any item card in a setup cycles through base/worn/consumable, persists to the database, and survives item sync operations.

+<!-- Key types and contracts the executor needs. Extracted from codebase. -->
+
+From src/db/schema.ts (setupItems table -- CURRENT, needs classification column added):
+```typescript
+export const setupItems = sqliteTable("setup_items", {
+  id: integer("id").primaryKey({ autoIncrement: true }),
+  setupId: integer("setup_id").notNull().references(() => setups.id, { onDelete: "cascade" }),
+  itemId: integer("item_id").notNull().references(() => items.id, { onDelete: "cascade" }),
+});
+```
+
+From src/server/services/setup.service.ts (functions to modify):
+```typescript
+type Db = typeof prodDb;
+export function getSetupWithItems(db: Db, setupId: number): { ...setup, items: [...] } | null;
+export function syncSetupItems(db: Db, setupId: number, itemIds: number[]): void;
+export function removeSetupItem(db: Db, setupId: number, itemId: number): void;
+```
+
+From src/shared/schemas.ts (existing pattern for enums):
+```typescript
+export const candidateStatusSchema = z.enum(["researching", "ordered", "arrived"]);
+```
+
+From src/client/lib/api.ts (existing helpers -- NO apiPatch exists):
+```typescript
+export async function apiGet<T>(url: string): Promise<T>;
+export async function apiPost<T>(url: string, body: unknown): Promise<T>;
+export async function apiPut<T>(url: string, body: unknown): Promise<T>;
+export async function apiDelete<T>(url: string): Promise<T>;
+```
+
+From src/client/hooks/useSetups.ts (existing types):
+```typescript
+interface SetupItemWithCategory {
+  id: number; name: string; weightGrams: number | null; priceCents: number | null;
+  categoryId: number; notes: string | null; productUrl: string | null;
+  imageFilename: string | null; createdAt: string; updatedAt: string;
+  categoryName: string; categoryIcon: string;
+}
+// NEEDS: classification field added to this interface
+```
+
+From src/client/components/StatusBadge.tsx (pattern reference for click interaction):
+```typescript
+// Uses click-to-open popup with status options
+// ClassificationBadge should be SIMPLER: direct click-to-cycle (only 3 values)
+// Must call e.stopPropagation() to prevent ItemCard click handler
+```
+
+From src/client/components/ItemCard.tsx (props interface -- badge goes in the badges area):
+```typescript
+interface ItemCardProps {
+  id: number; name: string; weightGrams: number | null; priceCents: number | null;
+  categoryName: string; categoryIcon: string; imageFilename: string | null;
+  productUrl?: string | null; onRemove?: () => void;
+}
+// Classification badge will be rendered OUTSIDE ItemCard, in the setup detail page's
+// grid layout, alongside the ItemCard. The ItemCard itself does NOT need modification.
+// The badge sits in the flex-wrap gap-1.5 area of ItemCard OR as a sibling element.
+```
+
+From tests/helpers/db.ts (setup_items CREATE TABLE -- needs classification column):
+```sql

+  </behavior>
+  <action>
+    1. **Update test helper FIRST** (`tests/helpers/db.ts`): Add `classification text NOT NULL DEFAULT 'base'` to the `setup_items` CREATE TABLE statement.
+
+    2. **Write failing tests** in `tests/services/setup.service.test.ts`:
+       - Add `describe("updateItemClassification", ...)` block with tests for setting classification and verifying the update
+       - Add test in existing `getSetupWithItems` describe for classification field presence (should default to "base")
+       - Add test in existing `syncSetupItems` describe for classification preservation (sync with different item list, verify classifications retained for items that remain)
+       - Add test for same item in two setups having different classifications
+       - Import the new `updateItemClassification` function from setup.service.ts
+
+    3. **Run tests** -- they must FAIL (RED phase).
+
+    4. **Update Drizzle schema** (`src/db/schema.ts`): Add `classification: text("classification").notNull().default("base")` to the `setupItems` table definition.
+
+    5. **Generate migration**: Run `bun run db:generate` to create the migration SQL file. Then run `bun run db:push` to apply.
+
+    6. **Add Zod schema** (`src/shared/schemas.ts`):
+       ```typescript
+       export const classificationSchema = z.enum(["base", "worn", "consumable"]);
+       export const updateClassificationSchema = z.object({
+         classification: classificationSchema,
+       });
+       ```
+
+    7. **Add types** (`src/shared/types.ts`): Add `UpdateClassification` type inferred from `updateClassificationSchema`. The `SetupItem` type auto-updates from Drizzle schema inference.
+
+    8. **Implement service functions** (`src/server/services/setup.service.ts`):
+       - Add `updateItemClassification(db, setupId, itemId, classification)` -- uses `db.update(setupItems).set({ classification }).where(sql\`..setupId AND ..itemId\`)`.
+       - Modify `getSetupWithItems` to include `classification: setupItems.classification` in the select fields.
+       - Modify `syncSetupItems` to preserve classifications using Approach A from research: before deleting, read existing classifications into a `Map<number, string>` (itemId -> classification). After re-inserting, apply saved classifications using `classificationMap.get(itemId) ?? "base"` in the insert values.
+
+    9. **Run tests** -- they must PASS (GREEN phase).

+  <action>
+    1. **Add PATCH route** (`src/server/routes/setups.ts`):
+       - Import `updateClassificationSchema` from schemas and `updateItemClassification` from service.
+       - Add `app.patch("/:id/items/:itemId/classification", zValidator("json", updateClassificationSchema), handler)`.
+       - Handler: extract `setupId` and `itemId` from params, `classification` from validated body, call `updateItemClassification(db, setupId, itemId, classification)`, return `{ success: true }`.
+
+    2. **Add integration test** (`tests/routes/setups.test.ts`):
+       - Add `describe("PATCH /api/setups/:id/items/:itemId/classification", ...)` block.
+       - Test: create setup, add item, PATCH classification to "worn", GET setup and verify item has classification "worn".
+       - Test: PATCH with invalid classification value returns 400.
+
+    3. **Add `apiPatch` helper** (`src/client/lib/api.ts`):
+       ```typescript
+       export async function apiPatch<T>(url: string, body: unknown): Promise<T> {
+         const res = await fetch(url, {
+           method: "PATCH",

+         });
+         return handleResponse<T>(res);
+       }
+       ```
+
+    4. **Update client hooks** (`src/client/hooks/useSetups.ts`):
+       - Add `classification: string` field to `SetupItemWithCategory` interface (defaults to "base" from API).
+       - Add `useUpdateItemClassification(setupId: number)` mutation hook:
+         ```typescript
+         export function useUpdateItemClassification(setupId: number) {
+           const queryClient = useQueryClient();
+           return useMutation({
+             mutationFn: ({ itemId, classification }: { itemId: number; classification: string }) =>
+               apiPatch<{ success: boolean }>(
+                 `/api/setups/${setupId}/items/${itemId}/classification`,
+                 { classification },
+               ),
+             onSuccess: () => {
+               queryClient.invalidateQueries({ queryKey: ["setups", setupId] });
+             },
+           });
+         }
+         ```
+       - Import `apiPatch` from `../lib/api`.
+
+    5. **Create ClassificationBadge component** (`src/client/components/ClassificationBadge.tsx`):
+       - Props: `classification: string`, `onCycle: () => void`.
+       - Define `CLASSIFICATION_ORDER = ["base", "worn", "consumable"] as const`.
+       - Define `CLASSIFICATION_LABELS = { base: "Base Weight", worn: "Worn", consumable: "Consumable" }`.
+       - Render as a `<button>` with pill styling: `bg-gray-100 text-gray-600 hover:bg-gray-200` (muted gray per user decision).
+       - Display the label text for the current classification.
+       - On click: call `e.stopPropagation()` (critical -- prevents ItemCard from opening edit panel), then call `onCycle()`.
+       - The parent component computes the next classification and calls the mutation.
+
+    6. **Wire into setup detail page** (`src/client/routes/setups/$setupId.tsx`):
+       - Import `ClassificationBadge` and `useUpdateItemClassification`.
+       - Create the mutation hook: `const updateClassification = useUpdateItemClassification(numericId)`.
+       - Add a helper function to compute next classification:
+         ```typescript
+         function nextClassification(current: string): string {
+           const order = ["base", "worn", "consumable"];
+           const idx = order.indexOf(current);
+           return order[(idx + 1) % order.length];
+         }
+         ```
+       - In the items grid, render `ClassificationBadge` below each `ItemCard` (as a sibling within the grid cell). Wrap ItemCard + badge in a `<div>`:
+         ```tsx
+         <div key={item.id}>
+           <ItemCard ... />
+           <div className="px-4 pb-3 -mt-1">
+             <ClassificationBadge
+               classification={item.classification}
+               onCycle={() => updateClassification.mutate({
+                 itemId: item.id,
+                 classification: nextClassification(item.classification),
+               })}
+             />
+           </div>
+         </div>
+         ```
+       - Alternatively, the badge can go inside the card's badge row if preferred. Use discretion on exact placement -- it should be near the weight/price badges but distinct.

+- Implemented classification-preserving syncSetupItems that saves/restores classifications across atomic re-sync
+- Built PATCH endpoint with Zod validation for updating item classification within a setup
+- Created ClassificationBadge component with click-to-cycle interaction (base weight -> worn -> consumable)
+- Wired badge into setup detail page below each ItemCard in the category-grouped grid
+- Added apiPatch client helper and useUpdateItemClassification mutation hook
+- 7 new tests (5 service, 2 route) covering classification CRUD, preservation, cross-setup independence, and validation
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Schema migration, service layer, and tests for classification** - `4491e4c` (feat - TDD red/green)
+2. **Task 2: API route, client hook, ClassificationBadge, and wiring** - `fb738d7` (feat)
+
+## Files Created/Modified
+- `src/db/schema.ts` - Added classification column to setupItems table
+- `drizzle/0003_misty_mongu.sql` - SQLite migration for classification column
+- `src/shared/schemas.ts` - Added classificationSchema and updateClassificationSchema
+- `src/shared/types.ts` - Added UpdateClassification type
+- `src/server/services/setup.service.ts` - Added updateItemClassification, modified getSetupWithItems and syncSetupItems
+- `src/server/routes/setups.ts` - Added PATCH /:id/items/:itemId/classification endpoint
+- `src/client/lib/api.ts` - Added apiPatch helper
+- `src/client/hooks/useSetups.ts` - Added classification field and useUpdateItemClassification hook
+- `src/client/components/ClassificationBadge.tsx` - New click-to-cycle badge component
+- `src/client/routes/setups/$setupId.tsx` - Wired ClassificationBadge into item grid
+- `tests/helpers/db.ts` - Added classification column to test schema
+- `tests/services/setup.service.test.ts` - Added 5 classification tests
+- `tests/routes/setups.test.ts` - Added 2 classification integration tests
+
+## Decisions Made
+- ClassificationBadge uses simple click-to-cycle rather than popup (only 3 values, simpler UX)
+- Classification stored on setupItems join table (not items table) so same item can have different roles in different setups
+- syncSetupItems preserves classifications by reading into Map<itemId, classification> before delete and restoring after re-insert
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+None
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
+- Classification data is available for weight breakdown visualization (Plan 09-02)
+- getSetupWithItems returns classification field for every item, ready for grouping by classification
+- All 121 tests pass across the full suite
+
+## Self-Check: PASSED
+
+All 14 files verified present. Both task commits (4491e4c, fb738d7) confirmed in git history.

+<objective>
+Add the WeightSummaryCard component with classification weight subtotals, a donut chart for weight distribution, and a pill toggle for switching between category and classification views.
+
+Purpose: Users need to visualize how weight is distributed across their setup -- both by gear category (shelter, sleep, cook) and by classification (base weight, worn, consumable). The donut chart with tooltips makes weight analysis intuitive.
+
+Output: A summary card below the setup sticky bar showing Base | Worn | Consumable | Total weight columns alongside a donut chart with interactive tooltips, togglable between category and classification breakdowns.

+    src/client/routes/setups/$setupId.tsx,
+    package.json
+  </files>
+  <action>
+    1. **Install Recharts**: Run `bun add recharts`. This adds recharts to package.json. React and react-dom are already peer deps in the project.
+
+    2. **Create WeightSummaryCard component** (`src/client/components/WeightSummaryCard.tsx`):
+
+       **Props interface:**
+       ```typescript
+       interface WeightSummaryCardProps {
+         items: SetupItemWithCategory[];  // from useSetups hook (includes classification field)
+       }
+       ```
+       Import `SetupItemWithCategory` from `../hooks/useSetups`.
+
+       **State:** `viewMode: "category" | "classification"` -- local React state, default "category".
+
+       **Weight subtotals computation** (derive from items array):
+       ```typescript
+       const baseWeight = items.reduce((sum, i) => i.classification === "base" ? sum + (i.weightGrams ?? 0) : sum, 0);
+       const wornWeight = items.reduce((sum, i) => i.classification === "worn" ? sum + (i.weightGrams ?? 0) : sum, 0);
+       const consumableWeight = items.reduce((sum, i) => i.classification === "consumable" ? sum + (i.weightGrams ?? 0) : sum, 0);
+       const totalWeight = baseWeight + wornWeight + consumableWeight;
+       ```
+
+       **Chart data transformation:**
+       - `buildCategoryChartData(items)`: Group by `categoryName`, sum `weightGrams`, compute percentage. Filter out zero-weight groups. Return `Array<{ name: string, weight: number, percent: number }>`.
+       - `buildClassificationChartData(items)`: Group by classification using labels ("Base Weight", "Worn", "Consumable"), sum weights, compute percentage. Filter out zero-weight groups.
+       - Select data source based on `viewMode`.
+
+       **Render structure:**
+       ```
+       <div className="bg-white rounded-xl border border-gray-100 p-5 mb-6">
+         <!-- Pill toggle: Category | Classification -->
+         <div className="flex items-center justify-between mb-4">

+           <!-- Donut chart -->
+           <div className="flex-shrink-0" style={{ width: 180, height: 180 }}>
+             <ResponsiveContainer width="100%" height={180}>

+                 <Tooltip content={<CustomTooltip unit={unit} />} />
+               </PieChart>
+             </ResponsiveContainer>

+             <SubtotalColumn label="Consumable" weight={consumableWeight} unit={unit} color="#10b981" />
+             <SubtotalColumn label="Total" weight={totalWeight} unit={unit} />
+           </div>
+         </div>
+       </div>
+       ```
+
+       **Pill toggle** (inline component or extracted):
+       - Two buttons in a `bg-gray-100 rounded-full` container: "Category" and "Classification".
+       - Active state: `bg-white text-gray-700 shadow-sm font-medium`. Inactive: `text-gray-400 hover:text-gray-600`.
+       - Same pattern as TotalsBar weight unit selector.
+
+       **SubtotalColumn** (inline component):
+       - Vertical stack: colored dot (if color provided), label in text-xs text-gray-500, weight value in text-sm font-semibold text-gray-900.
+
+       **CustomTooltip:**
+       - Props: `active`, `payload`, `unit` (WeightUnit).
+       - When active and payload exists, show: segment name (bold), weight formatted with `formatWeight()`, percentage as `(XX.X%)`.
+       - Styled: `bg-white border border-gray-200 rounded-lg shadow-lg px-3 py-2 text-sm`.
+
+       **Color selection:**
+       - When `viewMode === "category"`: use `CATEGORY_COLORS` array (cycle through for many categories).
+       - When `viewMode === "classification"`: use `CLASSIFICATION_COLORS` object (keyed by classification value).
+
+       **Edge cases:**
+       - If all items have null/zero weight, show a placeholder message ("No weight data to display") instead of the chart.
+       - If items array is empty, component should not render (handled by parent).
+
+    3. **Wire into setup detail page** (`src/client/routes/setups/$setupId.tsx`):
+       - Import `WeightSummaryCard` from `../../components/WeightSummaryCard`.
+       - Render `<WeightSummaryCard items={setup.items} />` between the actions bar and the items grid (before the `{itemCount > 0 && (` block), but INSIDE the `itemCount > 0` condition so it only shows when there are items.
+       - Exact placement: after the actions `<div>` and before the items-grouped-by-category `<div>`, within the `{itemCount > 0 && (...)}` block.
+
+    4. **Verify**: Run `bun run build` to ensure no TypeScript errors and Recharts imports resolve correctly.

+    2. Open http://localhost:5173 and navigate to a setup with items (or create one and add items)
+    3. **Classification badges**: Verify each item card shows a gray pill badge. Click it and confirm it cycles: "Base Weight" -> "Worn" -> "Consumable" -> "Base Weight". Confirm clicking the badge does NOT open the item edit panel.
+    4. **Classification persistence**: Refresh the page. Confirm classifications are preserved.
+    5. **Weight subtotals**: With items classified differently, verify the summary card shows correct subtotals for Base, Worn, Consumable, and Total columns.
+    6. **Donut chart (Category view)**: Verify the donut chart shows colored segments grouped by category. Hover segments to see tooltip with category name, weight, and percentage.
+    7. **Donut chart (Classification view)**: Click the "Classification" pill toggle. Verify chart segments change to show base/worn/consumable breakdown with different colors. Hover to verify tooltips.
+    8. **Donut center**: Confirm total weight is displayed in the center of the donut hole in the selected weight unit.
+    9. **Weight unit**: Toggle the weight unit in the top bar (if available). Confirm all subtotals, chart center, and tooltips update to the new unit.
+    10. **Add/remove items**: Add another item to the setup. Verify it appears with default "Base Weight" badge and the chart updates. Remove an item and verify classifications for remaining items are preserved.

+# Phase 9: Weight Classification and Visualization - Context
+
+**Gathered:** 2026-03-16
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+Users can classify each item within a setup as base weight, worn, or consumable (same item can differ across setups). Setup detail view shows weight subtotals by classification and a donut chart for weight distribution, toggleable between category and classification breakdowns. Side-by-side comparison, ranking, and impact preview are separate phases.
+
+</domain>
+
+<decisions>
+## Implementation Decisions
+
+### Classification UI
+- Click-to-cycle badge on each item card within a setup — clicks cycle through base weight → worn → consumable → base weight
+- Follows the StatusBadge pattern from Phase 8 (pill badge, click interaction)
+- Default classification is "base weight" when an item is added to a setup
+- Badge always visible on every item card in the setup (not hidden for default)
+- Muted gray color scheme for all classification badges (bg-gray-100 text-gray-600), consistent with Phase 8 status badges
+- Classification stored on `setup_items` join table (already decided in prior phases)
+
+### Weight subtotals display
+- Summary section below the setup sticky bar, always visible when setup has items
+- Card with columns layout: Base | Worn | Consumable | Total — each as a labeled column with weight value
+- Sticky bar keeps its existing simple stats (item count, total weight, total cost)
+- Summary card is a separate visual element, not inline text
+
+### Chart placement & style
+- Donut chart sits inside the summary card alongside the weight subtotals — chart + numbers as one visual unit
+- Pill toggle above the chart for switching between "Category" and "Classification" views (same style as weight unit selector)
+- Total weight displayed in the center of the donut hole (e.g., "2.87kg")
+- Hover tooltips show segment name, weight (in selected unit), and percentage

+## Existing Code Insights
+
+### Reusable Assets
+- `StatusBadge` (`src/client/components/StatusBadge.tsx`): Click-to-cycle pattern with popup — direct pattern reference for classification badge
+- `formatWeight()` in `src/client/lib/formatters.ts`: Handles unit conversion, reuse for subtotals and chart tooltips
+- `useWeightUnit()` hook: Gets current weight unit setting for display
+- `getSetupWithItems()` in `src/server/services/setup.service.ts`: Fetches setup items with category joins — needs to include classification field
+- `syncSetupItems()`: Delete-all + re-insert pattern — needs to preserve classification values
+
+### Established Patterns
+- Settings stored as key/value strings in SQLite `settings` table
+- React Query for server data, Zustand for UI-only state (panels/dialogs)
+- Pill badges: blue-50/blue-400 for weight, green-50/green-500 for price, gray-50/gray-600 for metadata
+- Weight unit pill toggle in TotalsBar — same pattern for chart category/classification toggle
+- Click-outside + Escape dismiss pattern for popups (CategoryPicker, StatusBadge)
+
+### Integration Points
+- `setup_items` table (`src/db/schema.ts`): Add `classification` column with default "base"
+- `getSetupWithItems()`: Include classification in query results
+- `syncSetupItems()`: Must handle classification when syncing (preserve during re-insert)
+- Setup detail page (`src/client/routes/setups/$setupId.tsx`): Add summary card section, classification badges on ItemCards, donut chart
+- `ItemCard` component: Needs optional `classification` prop and badge (only rendered in setup context)
+- Setup routes (`src/server/routes/setups.ts`): API needs to accept/return classification data
+- Test helper (`tests/helpers/db.ts`): Update CREATE TABLE for setup_items to include classification column

+# Phase 9: Weight Classification and Visualization - Research
+
+**Researched:** 2026-03-16
+**Domain:** Schema migration, classification UI, chart visualization (Recharts)
+**Confidence:** HIGH
+
+## Summary
+
+Phase 9 adds two features: (1) per-setup item classification (base weight / worn / consumable) stored on the `setup_items` join table, and (2) a donut chart visualization of weight distribution inside the setup detail page. The classification feature requires a schema migration adding a `classification` column with a default of `"base"` to `setup_items`, updates to the sync/query service layer, a new API endpoint for updating individual item classifications, and a click-to-cycle badge on each item card within setup context. The visualization feature requires installing Recharts and building a summary card component with a donut chart, weight subtotals, and a pill toggle for switching between category and classification breakdowns.
+
+The project has strong existing patterns to follow: the `StatusBadge` click-to-cycle component from Phase 8, the `formatWeight()` utility with `useWeightUnit()` hook, the TotalsBar pill toggle for weight units, and the Drizzle migration pattern established in prior phases (e.g., `0002_broken_roughhouse.sql` adding a column with `ALTER TABLE ... ADD`). Recharts v3.x is the decided chart library, which is mature, well-documented, and has a straightforward API for donut charts using `PieChart` + `Pie` with `innerRadius`.
+
+**Primary recommendation:** Use Recharts v3.x with `Cell` component for individual slice colors (still functional in v3, deprecated only for v4), `Label` for center text, and a custom `content` function on `Tooltip` for formatted hover data. Store classification as a text column on `setup_items` with a Zod enum for validation.

+
+## User Constraints (from CONTEXT.md)
+
+### Locked Decisions
+- Click-to-cycle badge on each item card within a setup -- clicks cycle through base weight -> worn -> consumable -> base weight
+- Follows the StatusBadge pattern from Phase 8 (pill badge, click interaction)
+- Default classification is "base weight" when an item is added to a setup
+- Badge always visible on every item card in the setup (not hidden for default)
+- Muted gray color scheme for all classification badges (bg-gray-100 text-gray-600), consistent with Phase 8 status badges
+- Classification stored on `setup_items` join table (already decided in prior phases)
+- Summary section below the setup sticky bar, always visible when setup has items
+- Card with columns layout: Base | Worn | Consumable | Total -- each as a labeled column with weight value
+- Sticky bar keeps its existing simple stats (item count, total weight, total cost)
+- Summary card is a separate visual element, not inline text
+- Donut chart sits inside the summary card alongside the weight subtotals -- chart + numbers as one visual unit
+- Pill toggle above the chart for switching between "Category" and "Classification" views (same style as weight unit selector)
+- Total weight displayed in the center of the donut hole (e.g., "2.87kg")
+- Hover tooltips show segment name, weight (in selected unit), and percentage
+- Chart library: **Recharts** (PieChart + Pie with innerRadius for donut shape)
+
+### Claude's Discretion
+- Summary card exact layout (chart left/right, column arrangement)
+- Chart color palette for segments (should work with both category and classification views)
+- Minimum item threshold for showing chart vs a placeholder message
+- Donut chart sizing and proportions
+- Tooltip styling
+- Keyboard accessibility for classification cycling
+- Animation on chart transitions between category/classification views

+
+## Standard Stack
+
+### Core
+| Library | Version | Purpose | Why Standard |
+|---------|---------|---------|--------------|
+| recharts | ^3.8.0 | Donut chart visualization | Most popular React charting library, declarative API, built on D3, 27K GitHub stars |
+
+### Supporting (already in project)
+| Library | Version | Purpose | When to Use |
+|---------|---------|---------|-------------|
+| drizzle-orm | ^0.45.1 | Schema migration for classification column | Add column to setup_items table |
+| zod | ^4.3.6 | Validation for classification enum | API input validation |
+| react | ^19.2.4 | UI components | Summary card, badge, chart wrapper |
+| tailwindcss | ^4.2.1 | Styling | Summary card layout, badge styling |
+
+### Alternatives Considered
+| Instead of | Could Use | Tradeoff |
+|------------|-----------|----------|
+| Recharts | Chart.js / react-chartjs-2 | Chart.js is imperative; Recharts is declarative React components -- better fit for this stack |
+| Recharts | Visx | Lower-level D3 wrapper; more control but more code for a simple donut chart |
+| Recharts | Tremor | Tremor wraps Recharts but adds full design system overhead -- too heavy for one chart |
+
+**Installation:**
+```bash
+bun add recharts
+```
+
+Note: Recharts has `react` and `react-dom` as peer dependencies, both already in the project. No additional peer deps needed.
+
+## Architecture Patterns
+
+### Schema Change: setup_items classification column
+
+```sql
+-- Migration: ALTER TABLE setup_items ADD classification text DEFAULT 'base' NOT NULL;
+ALTER TABLE `setup_items` ADD `classification` text DEFAULT 'base' NOT NULL;
+```
+
+The Drizzle schema change in `src/db/schema.ts`:
+```typescript
+export const setupItems = sqliteTable("setup_items", {
+  id: integer("id").primaryKey({ autoIncrement: true }),
+  setupId: integer("setup_id")
+    .notNull()
+    .references(() => setups.id, { onDelete: "cascade" }),
+  itemId: integer("item_id")
+    .notNull()
+    .references(() => items.id, { onDelete: "cascade" }),
+  classification: text("classification").notNull().default("base"),
+});
+```
+
+Values: `"base"` | `"worn"` | `"consumable"` -- stored as text, validated with Zod enum.
+
+### API Design: Classification Update
+
+A new `PATCH /api/setups/:id/items/:itemId/classification` endpoint is the cleanest approach. It avoids modifying the existing sync endpoint (which does delete-all + re-insert and would lose classifications).
+
+Alternatively, a dedicated `PATCH /api/setup-items/:setupItemId` could work, but using the composite key `(setupId, itemId)` is more consistent with the existing `DELETE /api/setups/:id/items/:itemId` pattern.
+
+**Use:** `PATCH /api/setups/:setupId/items/:itemId/classification` with body `{ classification: "worn" }`.
+
+### syncSetupItems Must Preserve Classifications
+
+The existing `syncSetupItems` function does delete-all + re-insert. After adding classification, this will reset all classifications to "base" whenever items are synced. Two approaches:
+
+**Approach A (recommended):** Before deleting, read existing classifications into a map `{ itemId -> classification }`. After re-inserting, apply the saved classifications. This keeps the atomic sync pattern intact.
+
+**Approach B:** Change sync to diff-based (add new, remove missing, keep existing). More complex, breaks the simple pattern.
+
+Use Approach A -- preserves the established pattern with minimal changes.
+
+### getSetupWithItems Must Include Classification
+
+The `getSetupWithItems` query needs to select `classification` from `setupItems`:
+
+```typescript
+const itemList = db
+  .select({
+    id: items.id,
+    name: items.name,
+    weightGrams: items.weightGrams,
+    priceCents: items.priceCents,
+    categoryId: items.categoryId,
+    // ... existing fields ...
+    categoryName: categories.name,
+    categoryIcon: categories.icon,
+    classification: setupItems.classification, // NEW
+  })
+  .from(setupItems)
+  .innerJoin(items, eq(setupItems.itemId, items.id))
+  .innerJoin(categories, eq(items.categoryId, categories.id))
+  .where(eq(setupItems.setupId, setupId))
+  .all();
+```
+
+### Component Architecture
+
+```
+src/client/
+  components/
+    ClassificationBadge.tsx     # Click-to-cycle badge (base/worn/consumable)
+    WeightSummaryCard.tsx       # Summary card: subtotals + donut chart
+  routes/
+    setups/
+      $setupId.tsx              # Modified: adds ClassificationBadge to ItemCard, adds WeightSummaryCard
+  hooks/
+    useSetups.ts                # Modified: add useUpdateItemClassification mutation, update types
+```
+
+### Pattern: ClassificationBadge (Click-to-Cycle)
+
+Follow the StatusBadge pattern but simplified -- no popup menu needed since there are only 3 values and the user cycles through them. Direct click-to-cycle is faster UX for 3 options.
+
+```typescript
+const CLASSIFICATION_ORDER = ["base", "worn", "consumable"] as const;
+type Classification = typeof CLASSIFICATION_ORDER[number];
+
+const CLASSIFICATION_CONFIG = {
+  base: { label: "Base Weight", icon: "backpack" },
+  worn: { label: "Worn", icon: "shirt" },
+  consumable: { label: "Consumable", icon: "droplets" },
+} as const;
+```
+
+Click handler cycles to next classification: `base -> worn -> consumable -> base`.
+
+### Pattern: Donut Chart with Recharts v3
+
+```typescript
+import { PieChart, Pie, Cell, Tooltip, Label, ResponsiveContainer } from "recharts";
+
+// Cell is still functional in v3 (deprecated for v4 removal)
+// This is the standard pattern for v3.x
+<ResponsiveContainer width="100%" height={200}>
+  <PieChart>
+    <Pie
+      data={chartData}
+      dataKey="weight"
+      nameKey="name"
+      cx="50%"
+      cy="50%"
+      innerRadius={55}
+      outerRadius={80}
+      paddingAngle={2}
+    >
+      {chartData.map((entry, index) => (
+        <Cell key={entry.name} fill={COLORS[index % COLORS.length]} />
+      ))}
+      <Label
+        value={formatWeight(totalWeight, unit)}
+        position="center"
+        className="text-lg font-semibold"
+      />
+    </Pie>
+    <Tooltip content={<CustomTooltip unit={unit} />} />
+  </PieChart>
+</ResponsiveContainer>
+```
+
+### Pattern: Custom Tooltip
+
+```typescript
+function CustomTooltip({ active, payload, unit }: any) {
+  if (!active || !payload?.length) return null;
+  const { name, weight, percent } = payload[0].payload;
+  return (
+    <div className="bg-white border border-gray-200 rounded-lg shadow-lg px-3 py-2 text-sm">
+      <p className="font-medium text-gray-900">{name}</p>
+      <p className="text-gray-600">
+        {formatWeight(weight, unit)} ({(percent * 100).toFixed(1)}%)
+      </p>
+    </div>
+  );
+}
+```
+
+### Pattern: Data Transformation for Chart
+
+```typescript
+// Category view: group items by category, sum weights
+function buildCategoryChartData(items: SetupItemWithCategory[]) {
+  const groups = new Map<string, number>();
+  for (const item of items) {
+    const current = groups.get(item.categoryName) ?? 0;
+    groups.set(item.categoryName, current + (item.weightGrams ?? 0));
+  }
+  const total = items.reduce((sum, i) => sum + (i.weightGrams ?? 0), 0);
+  return Array.from(groups.entries())
+    .filter(([_, weight]) => weight > 0)
+    .map(([name, weight]) => ({ name, weight, percent: total > 0 ? weight / total : 0 }));
+}
+
+// Classification view: group by classification, sum weights
+function buildClassificationChartData(items: SetupItemWithClassification[]) {
+  const groups = { base: 0, worn: 0, consumable: 0 };
+  for (const item of items) {
+    groups[item.classification] += item.weightGrams ?? 0;
+  }
+  const total = Object.values(groups).reduce((a, b) => a + b, 0);
+  return Object.entries(groups)
+    .filter(([_, weight]) => weight > 0)
+    .map(([key, weight]) => ({
+      name: CLASSIFICATION_CONFIG[key as Classification].label,
+      weight,
+      percent: total > 0 ? weight / total : 0,
+    }));
+}
+```
+
+### Pattern: Pill Toggle (View Mode Switcher)
+
+Reuse the exact pattern from TotalsBar's weight unit toggle:
+
+```typescript
+const VIEW_MODES = ["category", "classification"] as const;
+type ViewMode = typeof VIEW_MODES[number];
+
+const [viewMode, setViewMode] = useState<ViewMode>("category");
+
+// Rendered as:
+<div className="flex items-center gap-1 bg-gray-100 rounded-full px-1 py-0.5">
+  {VIEW_MODES.map((mode) => (
+    <button
+      key={mode}
+      onClick={() => setViewMode(mode)}
+      className={`px-2.5 py-0.5 text-xs rounded-full transition-colors capitalize ${
+        viewMode === mode
+          ? "bg-white text-gray-700 shadow-sm font-medium"
+          : "text-gray-400 hover:text-gray-600"
+      }`}
+    >
+      {mode === "category" ? "Category" : "Classification"}
+    </button>
+  ))}
+</div>
+```
+
+### Anti-Patterns to Avoid
+- **Modifying syncSetupItems to accept classifications in the itemIds array:** This couples the sync endpoint to classification data. Keep them separate -- sync manages membership, classification update manages role.
+- **Computing classification subtotals on the server:** The setup detail page already computes totals client-side from the items array. Keep classification subtotals client-side too for consistency.
+- **Using a separate table for classifications:** Overkill. A single column on `setup_items` is the right level of complexity.
+- **Using Recharts v4 patterns (RechartsSymbols.fill):** v4 is not released. Stick with `Cell` component which works in v3.x.
+
+## Don't Hand-Roll
+
+| Problem | Don't Build | Use Instead | Why |
+|---------|-------------|-------------|-----|
+| Donut chart rendering | Custom SVG arc calculations | Recharts `PieChart` + `Pie` | Arc math, hit detection, animation, accessibility -- all handled |
+| Chart tooltips | Custom hover position tracking | Recharts `Tooltip` with `content` prop | Viewport boundary detection, positioning, hover state management |
+| Responsive chart sizing | Manual resize observers | Recharts `ResponsiveContainer` | Handles debounced resize, prevents layout thrashing |
+| Weight unit formatting | Inline conversion in chart | Existing `formatWeight()` utility | Already handles all units with correct decimal places |
+
+**Key insight:** Recharts handles all the hard SVG/D3 work. The implementation should focus on data transformation (grouping items into chart segments) and styling (Tailwind classes on the summary card and tooltip).
+
+## Common Pitfalls
+
+### Pitfall 1: syncSetupItems Destroys Classifications
+**What goes wrong:** The existing sync function deletes all setup_items then re-inserts. After adding classification, every sync resets all items to "base".
+**Why it happens:** Delete-all + re-insert pattern was designed before classification existed.
+**How to avoid:** Save classifications before delete, restore after re-insert (Approach A above).
+**Warning signs:** Items losing their classification after adding/removing any item from the setup.
+
+### Pitfall 2: ResponsiveContainer Needs a Defined Parent Height
+**What goes wrong:** Recharts `ResponsiveContainer` with `height="100%"` renders at 0px if the parent container has no explicit height.
+**Why it happens:** CSS percentage heights require the parent to have a defined height.
+**How to avoid:** Use a fixed numeric height on `ResponsiveContainer` (e.g., `height={200}`) or ensure the parent div has an explicit height (e.g., `h-[200px]`).
+**Warning signs:** Chart not visible, 0-height container.
+
+### Pitfall 3: Chart Data with Zero-Weight Items
+**What goes wrong:** Items with `null` or `0` weight produce zero-size or NaN chart segments.
+**Why it happens:** Recharts renders slices proportional to `dataKey` values. Zero values create invisible or problematic slices.
+**How to avoid:** Filter out zero-weight entries before passing data to the chart. Show a "no weight data" placeholder if all items have null weight.
+**Warning signs:** Console warnings about NaN, invisible chart segments, misaligned tooltips.
+
+### Pitfall 4: Test Helper Must Match Schema
+**What goes wrong:** Tests fail because the in-memory DB schema in `tests/helpers/db.ts` doesn't include the new `classification` column.
+**Why it happens:** The test helper has hand-written CREATE TABLE statements that must be manually kept in sync with `src/db/schema.ts`.
+**How to avoid:** Update the test helper's `setup_items` CREATE TABLE to include `classification text NOT NULL DEFAULT 'base'` alongside updating the Drizzle schema.
+**Warning signs:** Tests failing with "no such column: classification" errors.
+
+### Pitfall 5: Classification Badge Click Propagates to ItemCard
+**What goes wrong:** Clicking the classification badge opens the item edit panel instead of cycling classification.
+**Why it happens:** ItemCard is a `<button>` element. Click events bubble up from the badge to the card.
+**How to avoid:** Call `e.stopPropagation()` on the classification badge click handler. This is the same pattern used by the remove button and product URL link on ItemCard.
+**Warning signs:** Edit panel opening when user tries to change classification.
+
+## Code Examples
+
+### Zod Schema for Classification
+
+```typescript
+// In src/shared/schemas.ts
+export const classificationSchema = z.enum(["base", "worn", "consumable"]);
+
+export const updateClassificationSchema = z.object({
+  classification: classificationSchema,
+});
+```
+
+### Service: Update Item Classification
+
+```typescript
+// In src/server/services/setup.service.ts
+export function updateItemClassification(
+  db: Db = prodDb,
+  setupId: number,
+  itemId: number,
+  classification: string,
+) {
+  return db
+    .update(setupItems)
+    .set({ classification })
+    .where(
+      sql`${setupItems.setupId} = ${setupId} AND ${setupItems.itemId} = ${itemId}`,
+    )
+    .run();
+}
+```
+
+### Service: syncSetupItems with Classification Preservation
+
+```typescript
+export function syncSetupItems(
+  db: Db = prodDb,
+  setupId: number,
+  itemIds: number[],
+) {
+  return db.transaction((tx) => {
+    // Save existing classifications before delete
+    const existing = tx
+      .select({
+        itemId: setupItems.itemId,
+        classification: setupItems.classification,
+      })
+      .from(setupItems)
+      .where(eq(setupItems.setupId, setupId))
+      .all();
+
+    const classificationMap = new Map(
+      existing.map((e) => [e.itemId, e.classification]),
+    );
+
+    // Delete all existing items for this setup
+    tx.delete(setupItems).where(eq(setupItems.setupId, setupId)).run();
+
+    // Re-insert with preserved classifications
+    for (const itemId of itemIds) {
+      tx.insert(setupItems)
+        .values({
+          setupId,
+          itemId,
+          classification: classificationMap.get(itemId) ?? "base",
+        })
+        .run();
+    }
+  });
+}
+```
+
+### Hook: useUpdateItemClassification
+
+```typescript
+// In src/client/hooks/useSetups.ts
+export function useUpdateItemClassification(setupId: number) {
+  const queryClient = useQueryClient();
+  return useMutation({
+    mutationFn: ({ itemId, classification }: { itemId: number; classification: string }) =>
+      apiPut<{ success: boolean }>(
+        `/api/setups/${setupId}/items/${itemId}/classification`,
+        { classification },
+      ),
+    onSuccess: () => {
+      queryClient.invalidateQueries({ queryKey: ["setups", setupId] });
+    },
+  });
+}
+```
+
+### Color Palette for Chart Segments
+
+```typescript
+// Category colors: distinguishable palette for up to 10 categories
+const CATEGORY_COLORS = [
+  "#6366f1", // indigo
+  "#f59e0b", // amber
+  "#10b981", // emerald
+  "#ef4444", // red
+  "#8b5cf6", // violet
+  "#06b6d4", // cyan
+  "#f97316", // orange
+  "#ec4899", // pink
+  "#14b8a6", // teal
+  "#84cc16", // lime
+];
+
+// Classification colors: 3 distinct colors matching the semantic meaning
+const CLASSIFICATION_COLORS = {
+  base: "#6366f1",       // indigo -- "foundation" feel
+  worn: "#f59e0b",       // amber -- "on your body" warmth
+  consumable: "#10b981", // emerald -- "used up" organic feel
+};
+```
+
+## State of the Art
+
+| Old Approach | Current Approach | When Changed | Impact |
+|--------------|------------------|--------------|--------|
+| Recharts `Cell` for per-slice colors | Still `Cell` in v3.x (deprecated for v4) | v3.0 deprecated, v4 removes | Use `Cell` now; plan to migrate to data-mapped colors when v4 drops |
+| Recharts v2 state management | Recharts v3 rewritten state | v3.0 (2024) | Better performance, fewer rendering bugs |
+| `activeShape` prop on Pie | `shape` prop with `isActive` callback | v3.0 | Use `shape` for custom active sectors if needed |
+
+**Deprecated/outdated:**
+- `Cell` component: Deprecated in v3, removed in v4. Still functional now. When v4 releases, migrate to `RechartsSymbols.fill` in data objects or `fillKey` prop.
+- `activeShape` / `inactiveShape` props on Pie: Deprecated in v3 in favor of unified `shape` prop.
+
+## Open Questions
+
+1. **Recharts bundle size impact**
+   - What we know: Recharts depends on D3 modules, adding ~50-80KB gzipped to the bundle
+   - What's unclear: Exact tree-shaking behavior with Vite and specific imports
+   - Recommendation: Import only needed components (`import { PieChart, Pie, Cell, Tooltip, Label, ResponsiveContainer } from "recharts"`) -- Vite will tree-shake unused parts
+
+2. **Chart animation performance**
+   - What we know: Recharts animations are CSS-based and generally smooth
+   - What's unclear: Whether toggling between category/classification views should animate the transition
+   - Recommendation: Enable default animation on initial render. For view toggles, let Recharts handle the re-render naturally (it will animate by default). If janky, set `isAnimationActive={false}`.

+
+**Confidence breakdown:**
+- Standard stack: HIGH - Recharts is the user's locked decision, v3.8.0 is current, API is well-documented
+- Architecture: HIGH - Classification column pattern mirrors the Phase 8 status column migration exactly; all code patterns verified against existing codebase
+- Pitfalls: HIGH - syncSetupItems preservation is the main risk; verified by reading the actual delete-all + re-insert code; other pitfalls are standard React/Recharts issues

+
+### Requirements Coverage
+
+| Requirement | Source Plan | Description | Status | Evidence |
+|---|---|---|---|---|
+| CLAS-01 | 09-01 | User can classify each item within a setup as base weight, worn, or consumable | SATISFIED | ClassificationBadge + PATCH endpoint + updateItemClassification service all wired and tested |
+| CLAS-02 | 09-02 | Setup totals display base weight, worn weight, consumable weight, and total separately | SATISFIED | WeightSummaryCard renders 4 SubtotalColumn components with computed weights |
+| CLAS-03 | 09-01 | Items default to "base weight" classification when added to a setup | SATISFIED | DB default "base" + syncSetupItems fallback + test confirms default |
+| CLAS-04 | 09-01 | Same item can have different classifications in different setups | SATISFIED | Classification on join table; cross-setup test passes |
+| VIZZ-01 | 09-02 | User can view a donut chart showing weight distribution by category in a setup | SATISFIED | Recharts PieChart with buildCategoryChartData, default viewMode="category" |
+| VIZZ-02 | 09-02 | User can toggle chart between category view and classification view | SATISFIED | Pill toggle with VIEW_MODES array, setViewMode state updates chartData source |
+| VIZZ-03 | 09-02 | User can hover chart segments to see category name, weight, and percentage | SATISFIED | CustomTooltip renders all three fields; passed to PieChart as `content` prop |
+
+No orphaned requirements — all 7 IDs declared in plan frontmatter and accounted for.
+
+---
+
+### Anti-Patterns Found
+
+No blockers or warnings found in modified files. The only `return null` instance is a standard React guard clause in CustomTooltip (not a stub).
+
+---
+
+### Human Verification Required
+
+The following items cannot be verified programmatically and require a running browser session:
+
+#### 1. Click-to-cycle badge interaction and stopPropagation
+
+**Test:** Open a setup with items. Click a classification badge on one item card.
+**Expected:** Badge label cycles Base Weight -> Worn -> Consumable -> Base Weight. The item edit panel does NOT open when clicking the badge.
+**Why human:** stopPropagation correctness and visual badge state update require browser execution.
+
+#### 2. Donut chart renders with correct segment proportions
+
+**Test:** Add items with different categories and weights to a setup. View the setup detail page.
+**Expected:** Donut chart segments are proportional to weight distribution. Total weight appears in the center hole.
+**Why human:** Chart rendering requires browser + Recharts layout.
+
+#### 3. Pill toggle switches chart data
+
+**Test:** Click the "Classification" pill on the WeightSummaryCard.
+**Expected:** Chart segments change from category-based colors to indigo/amber/emerald for base/worn/consumable. Tooltips show "Base Weight", "Worn", or "Consumable" labels.
+**Why human:** Visual and interactive behavior requires browser.
+
+#### 4. Tooltip on hover
+
+**Test:** Hover over a chart segment.
+**Expected:** Tooltip appears with segment name, formatted weight in the selected unit, and percentage.
+**Why human:** Hover state requires browser interaction.
+
+#### 5. Weight unit propagation
+
+**Test:** Toggle the weight unit in the top bar (g / oz / lb / kg). Observe WeightSummaryCard.
+**Expected:** All four subtotal columns and the donut center label update to the selected unit.
+**Why human:** useWeightUnit hook behavior and re-render requires browser.
+
+---
+
+### Test Suite Results
+
+All 121 tests pass across 10 files (32 setup-specific tests across services and routes).
+
+- `tests/services/setup.service.test.ts` — 5 new classification tests pass (default "base", preservation, new item default, cross-setup independence, update from base to worn)
+- `tests/routes/setups.test.ts` — 2 new PATCH classification tests pass (valid update + 400 for invalid value)
+
+---
+
+### Summary
+
+Phase 9 goal is fully achieved. All 9 observable truths are verified against the actual codebase — no stubs, no orphaned artifacts, no broken links. The complete vertical slice from DB schema to UI component is wired and exercised by 7 automated tests. Human verification is needed only for visual/interactive browser behaviors (chart rendering, hover tooltips, click cycling), which are structurally sound in the code.

+**Scope:** Client-side filtering of already-fetched data. No server changes needed -- the collection is small enough (single user) that client-side filtering is both simpler and faster.
+
+**Integration points:**
+
+| Layer | File | Change Type | Details |
+|-------|------|-------------|---------|
+| Client | `routes/collection/index.tsx` | MODIFY | Add search input and category filter dropdown above the gear grid in `CollectionView` |
+| Client | NEW `components/SearchBar.tsx` | NEW | Reusable search input component with clear button |
+| Client | `hooks/useItems.ts` | NO CHANGE | Already returns all items; filtering happens in the route |
+
+**Data flow:**
+
+```
+CollectionView (owns search/filter state via useState)
+    |
+    +-- SearchBar (controlled input, calls setSearchTerm)
+    +-- CategoryFilter (dropdown from useCategories, calls setCategoryFilter)
+    |
+    +-- Items = useItems().data
+        .filter(item => matchesSearch(item.name, searchTerm))
+        .filter(item => !categoryFilter || item.categoryId === categoryFilter)
+        |
+        +-- Grouped by category -> rendered as before
+```
+
+**Why client-side:** The `useItems()` hook already fetches all items. For a single-user app, even 500 items is trivially fast to filter in memory. Adding server-side search would mean new API parameters, new query logic, and pagination -- all unnecessary complexity. If the collection grows beyond ~2000 items someday, server-side search can be added to the existing `getAllItems` service function by accepting optional `search` and `categoryId` parameters and adding Drizzle `like()` + `eq()` conditions.
+
+**Pattern -- filtered items with useMemo:**
+
+```typescript
+// In CollectionView component
+const [searchTerm, setSearchTerm] = useState("");
+const [categoryFilter, setCategoryFilter] = useState<number | null>(null);
+
+const filteredItems = useMemo(() => {
+  if (!items) return [];
+  return items
+    .filter(item => {
+      if (!searchTerm) return true;
+      return item.name.toLowerCase().includes(searchTerm.toLowerCase());
+    })
+    .filter(item => {
+      if (!categoryFilter) return true;
+      return item.categoryId === categoryFilter;
+    });
+}, [items, searchTerm, categoryFilter]);
+```
+
+No debounce library needed -- `useMemo` re-computes on keystroke, and filtering an in-memory array of <1000 items is sub-millisecond. Debounce is only needed if triggering API calls.
+
+**The category filter already exists** in `PlanningView` (lines 191-209 and 277-290 in `collection/index.tsx`). The same pattern should be reused for the gear tab with an icon-aware dropdown replacing the plain `<select>`. The existing `useCategories` hook provides the category list.
+
+**Planning category filter upgrade:** The current plain `<select>` in PlanningView should be upgraded to an icon-aware dropdown that shows Lucide icons next to category names. This is a shared component that both the gear tab filter and the planning tab filter can use.
+
+---
+
+### Feature 2: Weight Classification (Base / Worn / Consumable)
+
+**Scope:** Per-item-per-setup classification. An item's classification depends on the setup context (a rain jacket might be "worn" in one setup and "base" in another). This means the classification lives on the `setup_items` join table, not on the `items` table.
+
+**Integration points:**
+
+| Layer | File | Change Type | Details |
+|-------|------|-------------|---------|
+| DB | `schema.ts` | MODIFY | Add `weightClass` column to `setup_items` |
+| DB | Drizzle migration | NEW | `ALTER TABLE setup_items ADD COLUMN weight_class TEXT NOT NULL DEFAULT 'base'` |
+| Shared | `schemas.ts` | MODIFY | Add `weightClass` to sync schema, add update schema |
+| Shared | `types.ts` | NO CHANGE | Types auto-infer from Drizzle schema |
+| Server | `setup.service.ts` | MODIFY | `getSetupWithItems` returns `weightClass`; add `updateSetupItemClass` function |
+| Server | `routes/setups.ts` | MODIFY | Add `PATCH /:id/items/:itemId` for classification update |
+| Client | `hooks/useSetups.ts` | MODIFY | `SetupItemWithCategory` type adds `weightClass`; add `useUpdateSetupItemClass` mutation |
+| Client | `routes/setups/$setupId.tsx` | MODIFY | Show classification badges, add toggle UI, compute classification totals |
+| Client | `components/ItemCard.tsx` | MODIFY | Accept optional `weightClass` prop for setup context |
+| Test | `tests/helpers/db.ts` | MODIFY | Add `weight_class` column to `setup_items` CREATE TABLE |
+
+**Schema change:**
+
+```typescript
+// In schema.ts -- setup_items table
+export const setupItems = sqliteTable("setup_items", {
+  id: integer("id").primaryKey({ autoIncrement: true }),
+  setupId: integer("setup_id")
+    .notNull()
+    .references(() => setups.id, { onDelete: "cascade" }),
+  itemId: integer("item_id")
+    .notNull()
+    .references(() => items.id, { onDelete: "cascade" }),
+  weightClass: text("weight_class").notNull().default("base"),
+  // Values: "base" | "worn" | "consumable"
+});
+```
+
+**Why on setup_items, not items:** LighterPack and all serious gear tracking tools classify items per-loadout. A sleeping bag is "base weight" in a backpacking setup but might not be in a day hike setup. The same pair of hiking boots is "worn weight" in every setup, but this is a user choice per context. Storing on the join table preserves this flexibility at zero additional complexity -- the `setup_items` table already exists.
+
+**New endpoint for classification update:**
+
+The existing sync pattern (delete-all + re-insert) would destroy classification data on every item add/remove. Instead, add a targeted update endpoint:
+
+```typescript
+// In setup.service.ts
+export function updateSetupItemClass(
+  db: Db,
+  setupId: number,
+  itemId: number,
+  weightClass: "base" | "worn" | "consumable",
+) {
+  return db
+    .update(setupItems)
+    .set({ weightClass })
+    .where(
+      sql`${setupItems.setupId} = ${setupId} AND ${setupItems.itemId} = ${itemId}`,
+    )
+    .run();
+}
+```
+
+```typescript
+// In routes/setups.ts -- new PATCH route
+app.patch("/:setupId/items/:itemId", zValidator("json", updateSetupItemClassSchema), (c) => {
+  const db = c.get("db");
+  const setupId = Number(c.req.param("setupId"));
+  const itemId = Number(c.req.param("itemId"));
+  const { weightClass } = c.req.valid("json");
+  updateSetupItemClass(db, setupId, itemId, weightClass);
+  return c.json({ success: true });
+});
+```
+
+**Also update syncSetupItems** to preserve existing classifications or accept them:
+
+```typescript
+// Updated syncSetupItems to accept optional weightClass
+export function syncSetupItems(
+  db: Db,
+  setupId: number,
+  items: Array<{ itemId: number; weightClass?: string }>,
+) {
+  return db.transaction((tx) => {
+    tx.delete(setupItems).where(eq(setupItems.setupId, setupId)).run();
+    for (const item of items) {
+      tx.insert(setupItems)
+        .values({
+          setupId,
+          itemId: item.itemId,
+          weightClass: item.weightClass ?? "base",
+        })
+        .run();
+    }
+  });
+}
+```
+
+**Sync schema update:**
+
+```typescript
+export const syncSetupItemsSchema = z.object({
+  items: z.array(z.object({
+    itemId: z.number().int().positive(),
+    weightClass: z.enum(["base", "worn", "consumable"]).default("base"),
+  })),
+});
+```
+
+This is a **breaking change** to the sync API shape (from `{ itemIds: number[] }` to `{ items: [...] }`). The single call site is `useSyncSetupItems` in `useSetups.ts`, called from `ItemPicker.tsx`.
+
+**Client-side classification totals** are computed from the setup items array, not from a separate API:
+
+```typescript
+const baseWeight = setup.items
+  .filter(i => i.weightClass === "base")
+  .reduce((sum, i) => sum + (i.weightGrams ?? 0), 0);
+
+const wornWeight = setup.items
+  .filter(i => i.weightClass === "worn")
+  .reduce((sum, i) => sum + (i.weightGrams ?? 0), 0);
+
+const consumableWeight = setup.items
+  .filter(i => i.weightClass === "consumable")
+  .reduce((sum, i) => sum + (i.weightGrams ?? 0), 0);
+```
+
+**UI for classification toggle:** A three-segment toggle on each item card within the setup detail view. Clicking a segment calls `useUpdateSetupItemClass`. The three segments use the same pill-tab pattern already used for Active/Resolved in PlanningView.
+
+---
+
+### Feature 3: Weight Distribution Visualization
+
+**Scope:** Donut chart showing weight breakdown by category (on collection page) and by classification (on setup detail page). Uses `react-minimal-pie-chart` (~2kB gzipped) instead of Recharts (~45kB) because this is the only chart in the app.
+
+**Integration points:**
+
+| Layer | File | Change Type | Details |
+|-------|------|-------------|---------|
+| Package | `package.json` | MODIFY | Add `react-minimal-pie-chart` dependency |
+| Client | NEW `components/WeightChart.tsx` | NEW | Reusable donut chart component |
+| Client | `routes/collection/index.tsx` | MODIFY | Add chart above category list in gear tab |
+| Client | `routes/setups/$setupId.tsx` | MODIFY | Add classification breakdown chart |
+| Client | `hooks/useTotals.ts` | NO CHANGE | Already returns `CategoryTotals[]` with weights |
+
+**Why react-minimal-pie-chart over Recharts:** The app needs exactly one chart type (donut/pie). Recharts adds ~45kB gzipped for a full charting library when only the PieChart component is used. `react-minimal-pie-chart` is <3kB gzipped, has zero dependencies beyond React, supports donut charts via `lineWidth` prop, includes animation, and provides label support. It is the right tool for a focused need.
+
+**Chart component pattern:**
+
+```typescript
+// components/WeightChart.tsx
+import { PieChart } from "react-minimal-pie-chart";
+
+interface WeightChartProps {
+  segments: Array<{
+    label: string;
+    value: number;    // weight in grams (always grams internally)
+    color: string;
+  }>;
+  size?: number;
+}
+
+export function WeightChart({ segments, size = 200 }: WeightChartProps) {
+  const filtered = segments.filter(s => s.value > 0);
+  if (filtered.length === 0) return null;
+
+  return (
+    <PieChart
+      data={filtered.map(s => ({
+        title: s.label,
+        value: s.value,
+        color: s.color,
+      }))}
+      lineWidth={35}          // donut style
+      paddingAngle={2}
+      rounded
+      animate
+      animationDuration={500}
+      style={{ height: size, width: size }}
+    />
+  );
+}
+```
+
+**Two usage contexts:**
+
+1. **Collection page** -- weight by category. Data source: `useTotals().data.categories`. Each `CategoryTotals` already has `totalWeight` and `categoryName`. Assign a consistent color per category (use category index mapped to a palette array).
+
+2. **Setup detail page** -- weight by classification. Data source: computed from `setup.items` grouping by `weightClass`. Three fixed colors for base/worn/consumable.
+
+**Color palette for categories:**
+
+```typescript
+const CATEGORY_COLORS = [
+  "#6B7280", "#3B82F6", "#10B981", "#F59E0B",
+  "#EF4444", "#8B5CF6", "#EC4899", "#14B8A6",
+  "#F97316", "#6366F1", "#84CC16", "#06B6D4",
+];
+
+function getCategoryColor(index: number): string {
+  return CATEGORY_COLORS[index % CATEGORY_COLORS.length];
+}
+```
+
+**Classification colors (matching the app's muted palette):**
+
+```typescript
+const CLASSIFICATION_COLORS = {
+  base: "#6B7280",       // gray -- the core pack weight
+  worn: "#3B82F6",       // blue -- on your body
+  consumable: "#F59E0B", // amber -- gets used up
+};
+```
+
+**Chart placement:** On the collection page, the chart appears as a compact summary card above the category-grouped items, alongside the global totals. On the setup detail page, it appears in the sticky sub-bar area or as a collapsible section showing base/worn/consumable breakdown with a legend. Keep it compact -- this is a supplementary visualization, not the primary UI.
+
+---
+
+### Feature 4: Candidate Status Tracking
+
+**Scope:** Track candidate lifecycle from "researching" through "ordered" to "arrived". This is a column on the `thread_candidates` table, displayed as a badge on `CandidateCard`, and editable inline.
+
+**Integration points:**
+
+| Layer | File | Change Type | Details |
+|-------|------|-------------|---------|
+| DB | `schema.ts` | MODIFY | Add `status` column to `thread_candidates` |
+| DB | Drizzle migration | NEW | `ALTER TABLE thread_candidates ADD COLUMN status TEXT NOT NULL DEFAULT 'researching'` |
+| Shared | `schemas.ts` | MODIFY | Add `status` to candidate schemas |
+| Server | `thread.service.ts` | MODIFY | Include `status` in candidate creates and updates |
+| Server | `routes/threads.ts` | NO CHANGE | Already passes through all candidate fields |
+| Client | `hooks/useThreads.ts` | MODIFY | `CandidateWithCategory` type adds `status` |
+| Client | `hooks/useCandidates.ts` | NO CHANGE | `useUpdateCandidate` already handles partial updates |
+| Client | `components/CandidateCard.tsx` | MODIFY | Show status badge, add click-to-cycle |
+| Client | `components/CandidateForm.tsx` | MODIFY | Add status selector to form |
+| Test | `tests/helpers/db.ts` | MODIFY | Add `status` column to `thread_candidates` CREATE TABLE |
+
+**Schema change:**
+
+```typescript
+// In schema.ts -- thread_candidates table
+export const threadCandidates = sqliteTable("thread_candidates", {
+  // ... existing fields ...
+  status: text("status").notNull().default("researching"),
+  // Values: "researching" | "ordered" | "arrived"
+});
+```
+
+**Status badge colors (matching app's muted palette from v1.1):**
+
+```typescript
+const CANDIDATE_STATUS_STYLES = {
+  researching: "bg-gray-100 text-gray-600",
+  ordered:     "bg-amber-50 text-amber-600",
+  arrived:     "bg-green-50 text-green-600",
+} as const;
+```
+
+**Inline status cycling:** On `CandidateCard`, clicking the status badge cycles to the next state (researching -> ordered -> arrived). This calls the existing `useUpdateCandidate` mutation with just the status field. No new endpoint needed -- the `updateCandidate` service already accepts partial updates via `updateCandidateSchema.partial()`.
+
+```typescript
+// In CandidateCard
+const STATUS_ORDER = ["researching", "ordered", "arrived"] as const;
+
+function cycleStatus(current: string) {
+  const idx = STATUS_ORDER.indexOf(current as any);
+  return STATUS_ORDER[(idx + 1) % STATUS_ORDER.length];
+}
+
+// onClick handler for status badge:
+updateCandidate.mutate({
+  candidateId: id,
+  status: cycleStatus(status),
+});
+```
+
+**Candidate creation default:** New candidates default to "researching". The `createCandidateSchema` includes `status` as optional with default.
+
+```typescript
+export const createCandidateSchema = z.object({
+  // ... existing fields ...
+  status: z.enum(["researching", "ordered", "arrived"]).default("researching"),
+});
+```
+
+---
+
+### Feature 5: Weight Unit Selection
+
+**Scope:** User preference stored in the `settings` table, applied globally across all weight displays. The database always stores grams -- unit conversion is a display-only concern handled in the client formatter.
+
+**Integration points:**
+
+| Layer | File | Change Type | Details |
+|-------|------|-------------|---------|
+| DB | `settings` table | NO SCHEMA CHANGE | Uses existing key-value `settings` table: `{ key: "weightUnit", value: "g" }` |
+| Server | Settings routes | NO CHANGE | Existing `GET/PUT /api/settings/:key` handles this |
+| Client | `hooks/useSettings.ts` | MODIFY | Add `useWeightUnit` convenience hook |
+| Client | `lib/formatters.ts` | MODIFY | `formatWeight` accepts unit parameter |
+| Client | NEW `hooks/useFormatWeight.ts` | NEW | Hook combining weight unit setting + formatter |
+| Client | ALL components showing weight | MODIFY | Use new formatting approach |
+| Client | `components/ItemForm.tsx` | MODIFY | Weight input label shows current unit, converts on submit |
+| Client | `components/CandidateForm.tsx` | MODIFY | Same as ItemForm |
+| Client | NEW `components/UnitSelector.tsx` | NEW | Unit picker UI (segmented control or dropdown) |
+
+**Settings approach -- why not a new table:**
+
+The `settings` table already exists with a `key/value` pattern, and `useSettings.ts` already has `useSetting(key)` and `useUpdateSetting`. Adding weight unit is:
+
+```typescript
+// In useSettings.ts
+export function useWeightUnit() {
+  return useSetting("weightUnit"); // Returns "g" | "oz" | "lb" | "kg" or null (default to "g")
+}
+```
+
+**Conversion constants:**
+
+```typescript
+const GRAMS_PER_UNIT = {
+  g:  1,
+  oz: 28.3495,
+  lb: 453.592,
+  kg: 1000,
+} as const;
+
+type WeightUnit = keyof typeof GRAMS_PER_UNIT;
+```
+
+**Modified formatWeight:**
+
+```typescript
+export function formatWeight(
+  grams: number | null | undefined,
+  unit: WeightUnit = "g",
+): string {
+  if (grams == null) return "--";
+  const converted = grams / GRAMS_PER_UNIT[unit];
+  const decimals = unit === "g" ? 0 : unit === "kg" ? 2 : 1;
+  return `${converted.toFixed(decimals)} ${unit}`;
+}
+```
+
+**Threading unit through components -- custom hook approach:**
+
+Create a `useFormatWeight()` hook. Components call it to get a unit-aware formatter. No React Context needed -- `useSetting()` already provides reactive data through React Query.
+
+```typescript
+// hooks/useFormatWeight.ts
+import { useSetting } from "./useSettings";
+import { formatWeight as rawFormat, type WeightUnit } from "../lib/formatters";
+
+export function useFormatWeight() {
+  const { data: unitSetting } = useSetting("weightUnit");
+  const unit = (unitSetting ?? "g") as WeightUnit;
+
+  return {
+    unit,
+    formatWeight: (grams: number | null | undefined) => rawFormat(grams, unit),
+  };
+}
+```
+
+Components that display weight (ItemCard, CandidateCard, CategoryHeader, TotalsBar, SetupDetailPage) call `const { formatWeight } = useFormatWeight()` instead of importing `formatWeight` directly from `lib/formatters.ts`. This is 6-8 call sites to update.
+
+**Weight input handling:** When the user enters weight in the form, the input accepts the selected unit and converts to grams before sending to the API. The label changes from "Weight (g)" to "Weight (oz)" etc.
+
+```typescript
+// In ItemForm, the label reads from the hook
+const { unit } = useFormatWeight();
+// Label: `Weight (${unit})`
+
+// On submit, before payload construction:
+const weightGrams = form.weightValue
+  ? Number(form.weightValue) * GRAMS_PER_UNIT[unit]
+  : undefined;
+```
+
+**When editing an existing item**, the form pre-fills by converting stored grams back to the display unit:
+
+```typescript
+const displayWeight = item.weightGrams != null
+  ? (item.weightGrams / GRAMS_PER_UNIT[unit]).toFixed(unit === "g" ? 0 : unit === "kg" ? 2 : 1)
+  : "";
+```
+
+**Unit selector placement:** In the TotalsBar component. The user sees the unit right where weights are displayed and can switch inline. A small segmented control or dropdown next to the weight display in the top bar.

+## Build Order (Dependency-Aware)
+
+The features have specific dependencies that dictate build order.
+
+```
+Phase 1: Weight Unit Selection
+  +-- Modifies formatWeight which is used everywhere
+  +-- Must be done first so subsequent weight displays use the new formatter
+  +-- Dependencies: none (uses existing settings infrastructure)
+
+Phase 2: Search/Filter
+  +-- Pure client-side addition, no schema changes
+  +-- Can be built independently
+  +-- Dependencies: none
+
+Phase 3: Candidate Status Tracking
+  +-- Schema migration (simple column add)
+  +-- Minimal integration surface
+  +-- Dependencies: none (but batch schema migration with Phase 4)
+
+Phase 4: Weight Classification
+  +-- Schema migration + sync API change + new PATCH endpoint
+  +-- Requires weight unit work to be done (displays classification totals)
+  +-- Dependencies: Phase 1 (weight formatting)
+
+Phase 5: Weight Distribution Charts
+  +-- Depends on weight classification (for setup breakdown chart)
+  +-- Depends on weight unit (chart labels need formatted weights)
+  +-- Dependencies: Phase 1 + Phase 4
+  +-- npm dependency: react-minimal-pie-chart
+```
+
+**Batch Phase 3 and Phase 4 schema migrations into one Drizzle migration** since they both add columns. Run `bun run db:generate` once after both schema changes are made.

+
+## Anti-Patterns to Avoid
+
+### Anti-Pattern 1: Server-Side Search for Small Collections
+
+**What people do:** Build a search API with pagination, debounced requests, loading states
+**Why it's wrong for this app:** Single-user app with <1000 items. Server round-trips add latency and complexity for zero benefit. Client already has all items in React Query cache.
+**Do this instead:** Filter in-memory using `useMemo` over the cached items array.
+
+### Anti-Pattern 2: Weight Classification on the Items Table
+
+**What people do:** Add `weightClass` column to `items` table
+**Why it's wrong:** An item's classification is context-dependent -- the same item can be "base" in one setup and not present in another. Putting it on `items` forces a single global classification.
+**Do this instead:** Put `weightClass` on `setup_items` join table. This is how LighterPack and every serious gear tracker works.
+
+### Anti-Pattern 3: Converting Stored Values to User's Unit
+
+**What people do:** Store weights in the user's preferred unit, or convert on the server before sending
+**Why it's wrong:** Changing the unit preference would require re-interpreting all stored data. Different users (future multi-user) might prefer different units from the same data.
+**Do this instead:** Always store grams in the database. Convert to display unit only in the client formatter. The conversion is a pure function with no side effects.
+
+### Anti-Pattern 4: Heavy Charting Library for One Chart Type
+
+**What people do:** Install Recharts (~45kB) or Chart.js (~67kB) for a single donut chart
+**Why it's wrong:** Massive bundle size overhead for minimal usage. These libraries are designed for dashboards with many chart types.
+**Do this instead:** Use `react-minimal-pie-chart` (<3kB) which does exactly donut/pie charts with zero dependencies.
+
+### Anti-Pattern 5: React Context Provider for Weight Unit
+
+**What people do:** Build a full React Context provider with `createContext`, `useContext`, a Provider wrapper component
+**Why it's excessive here:** The `useSetting("weightUnit")` hook already provides reactive data through React Query. Adding a Context layer on top adds indirection for no benefit.
+**Do this instead:** Create a simple custom hook `useFormatWeight()` that internally calls `useSetting("weightUnit")`. React Query already handles caching and reactivity.

+# Feature Research: v1.2 Collection Power-Ups
+
+**Domain:** Gear management -- search/filter, weight classification, weight visualization, candidate status tracking, weight unit selection
+**Researched:** 2026-03-16
+**Confidence:** HIGH
+**Scope:** New features only. v1.0/v1.1 features (item CRUD, categories, threads, setups, dashboard, onboarding, images, icons) are already shipped.
+
+## Table Stakes
+
+Features that gear management users expect. Missing these makes the app feel incomplete for collections beyond ~20 items.
+
+| Feature | Why Expected | Complexity | Dependencies on Existing |
+|---------|--------------|------------|--------------------------|
+| Search items by name | Every competitor with an inventory concept has search. Hikt highlights "searchable digital closet." PackLight Supporter Edition has inventory search. Once a collection exceeds 30 items, scrolling to find something is painful. LighterPack notably lacks this and users complain. | LOW | Items query (`useItems`), collection view. Client-side only -- no API changes needed for <500 items. |
+| Filter items by category | Already partially exists in Planning view (category dropdown for threads). Collection view groups by category visually but has no filter. Users need to quickly narrow to "show me just my shelter items." | LOW | Categories query (`useCategories`), collection view. Client-side filtering of already-fetched items. |
+| Weight unit selection (g, oz, lb, kg) | Universal across all competitors. LighterPack supports toggling between g/oz/lb/kg. Packrat offers per-item input in any unit with display conversion. Backpacking Light forum users specifically praise apps that let you "enter item weights in grams and switch the entire display to lbs & oz." Gear specs come in mixed units -- a sleeping bag in lbs/oz, a fuel canister in grams. | LOW | `formatWeight()` in `lib/formatters.ts`, `settings` table (already exists with key/value store), TotalsBar, ItemCard, CandidateCard, SetupCard -- every weight display. |
+| Weight classification (base/worn/consumable) | LighterPack pioneered this three-way split and it is now universal. Hikt, PackLight, Packstack, HikeLite, 99Boulders spreadsheet -- all support it. "Base weight" is the core metric of the ultralight community. Without classification, weight totals are a single number with no actionable insight. | MEDIUM | `setup_items` join table (needs new column), setup detail view, setup service, totals computation. Schema migration required. |
+
+## Differentiators
+
+Features that set GearBox apart or add meaningful value beyond what competitors offer.
+
+| Feature | Value Proposition | Complexity | Dependencies on Existing |
+|---------|-------------------|------------|--------------------------|
+| Weight distribution visualization (donut/pie chart) | LighterPack's pie chart is iconic and widely cited as its best feature. "The pie chart at the top is a great way to visualize how your pack weight breaks down by category." PackLight uses bar graphs. GearBox can do this per-setup with a modern donut chart that also shows base/worn/consumable breakdown -- a combination no competitor offers cleanly. | MEDIUM | Totals data (already computed server-side per category), weight classification (new), a chart library (react-minimal-pie-chart at 2kB or Recharts). |
+| Candidate status tracking (researching/ordered/arrived) | No competitor has this. Research confirmed: the specific workflow of tracking purchase status through stages does not exist in any gear management app. This is unique to GearBox's planning thread concept. It makes threads a living document of the purchase lifecycle, not just a comparison tool. | LOW | `thread_candidates` table (needs new `status` column), CandidateCard, CandidateForm. Simple text field migration. |
+| Planning category filter with icon-aware dropdown | Already partially built as a plain `<select>` in PlanningView. Upgrading to show Lucide icons alongside category names makes filtering feel polished and consistent with the icon picker UX. | LOW | Existing CategoryPicker component pattern, existing category filter state in PlanningView. |
+| Weight classification shown per-setup (not global) | In LighterPack, worn/consumable flags are per-item within a list. In GearBox, items exist in a global collection and appear in multiple setups. The same jacket might be "worn" in a summer bikepacking setup but "base weight" (packed in panniers) in a winter setup. Classification belongs on the setup_items join, not on the item itself. This is architecturally superior to competitors. | MEDIUM | `setup_items` table schema, setup sync endpoint, setup detail UI. |
+
+## Anti-Features
+
+Features to explicitly NOT build in this milestone.
+
+| Anti-Feature | Why Avoid | What to Do Instead |
+|--------------|-----------|-------------------|
+| Per-item weight input in multiple units | Packrat lets you enter "2 lb 3 oz" per item. This adds parsing complexity, ambiguous storage, and conversion bugs. | Store grams internally (already done). Convert for display only. Users enter grams; if they want oz input, they convert mentally or we add a unit toggle on the input field later. |
+| Interactive chart drill-down (click to zoom) | LighterPack lets you click pie slices to zoom into category breakdowns. Adds significant interaction complexity. | Static donut chart with hover tooltips. Drill-down is a future enhancement. |
+| Weight goals / targets ("your target base weight is X") | Some apps show ultralight thresholds. Adds opinionated norms that conflict with hobby-agnostic design. | Show the numbers. Let users interpret them. |
+| Custom weight classification labels | Beyond base/worn/consumable. Some users want "luxury" or "shared" categories. | Three classifications cover 95% of use cases. The notes field handles edge cases. |
+| Server-side search / full-text search | SQLite FTS5 or similar. Premature for a single-user app with <1000 items. | Client-side filtering of the already-fetched items array. Simpler, faster for the expected data scale. |
+| Worn/consumable at the global item level | Tempting to add a classification column to the `items` table. | Classification varies by setup context. A rain shell is "worn" on a day hike but "base weight" (packed) on a bike tour. The join table `setup_items` is the correct location. |
+
+## Feature Details
+
+### 1. Search and Filter
+
+**What users expect:** A text input that filters visible items by name as you type. A category dropdown or pill selector to filter by category. Both should work together (search within a category).
+
+**Domain patterns observed:**
+- Hikt: Searchable gear closet with category and specification filters
+- PackLight: Inventory search (premium feature) with category organization
+- Backpacking Light Calculator: Search filter in gear locker and within packs
+- LighterPack: No text search -- widely considered a gap
+
+**Recommended implementation:**
+- Sticky search bar above the collection grid with a text input and category filter dropdown
+- Client-side filtering using `Array.filter()` on the items array from `useItems()`
+- Case-insensitive substring match on item name
+- Category filter as pills or dropdown (reuse the pattern from PlanningView)
+- URL search params for filter state (shareable filtered views, consistent with existing `?tab=` pattern)
+- Clear filters button when any filter is active
+- Result count displayed ("showing 12 of 47 items")
+
+**Complexity:** LOW. Pure client-side. No API changes. ~100 lines of new component code plus minor state management.
+
+### 2. Weight Classification (Base/Worn/Consumable)
+
+**What users expect:** Every item in a setup can be marked as one of three types:
+- **Base weight**: Items carried in the pack. The fixed weight of your loadout. This is the primary metric ultralight hikers optimize.
+- **Worn weight**: Items on your body while hiking (shoes, primary clothing, watch, sunglasses). Not counted toward pack weight but tracked as part of "skin-out" weight.
+- **Consumable weight**: Items that deplete during a trip (food, water, fuel, sunscreen). Variable weight not counted toward base weight.
+
+**Domain patterns observed:**
+- LighterPack: Per-item icons (shirt icon = worn, flame icon = consumable). Default = base weight. Totals show base/worn/consumable/total separately.
+- Packstack: "Separates base weight, worn weight, and consumables so you always know exactly what your pack weighs."
+- HikeLite: "Mark heavy clothing as worn to see your true base weight."
+- 99Boulders spreadsheet: Column with dropdown: WORN / CONSUMABLE / - (dash = base).
+
+**Critical design decision -- classification scope:**
+In LighterPack, items only exist within lists, so the flag is per-item-per-list inherently. In GearBox, items live in a global collection and are referenced by setups. The classification MUST live on the `setup_items` join table, not on the `items` table. Reason: the same item can have different classifications in different setups (a puffy jacket is "worn" on a cold-weather hike but "base weight" in a three-season setup where it stays packed).
+
+**Recommended implementation:**
+- Add `classification TEXT NOT NULL DEFAULT 'base'` column to `setup_items` table
+- Valid values: `"base"`, `"worn"`, `"consumable"`
+- Default to `"base"` (most items are base weight; this matches user expectation)
+- UI: Small segmented control or icon toggle on each item within the setup detail view
+- LighterPack-style icons: backpack icon (base), shirt icon (worn), flame/droplet icon (consumable)
+- Setup totals recalculated: show base weight, worn weight, consumable weight, and total (skin-out) as four separate numbers
+- SQL aggregation update: `SUM(CASE WHEN classification = 'base' THEN weight_grams ELSE 0 END)` etc.
+
+**Complexity:** MEDIUM. Requires schema migration, API changes (sync endpoint must accept classification), service layer updates, and UI for per-item classification within setup views.
+
+### 3. Weight Distribution Visualization
+
+**What users expect:** A chart showing where the weight is. By category is standard. By classification (base/worn/consumable) is a bonus.
+
+**Domain patterns observed:**
+- LighterPack: Color-coded pie chart by category, click to drill down. "As you enter each piece of equipment, a pie chart immediately displays a breakdown of where your weight is appropriated." Colors are customizable per category.
+- PackLight: Bar graph comparing category weights
+- OutPack: Category breakdown graph
+
+**Two chart contexts:**
+1. **Collection-level**: Weight by category across the whole collection. Uses existing `useTotals()` data.
+2. **Setup-level**: Weight by category AND by classification within a specific setup. More useful because setups represent actual loadouts.
+
+**Recommended implementation:**
+- Donut chart (modern feel, consistent with GearBox's minimalist aesthetic)
+- Library: `react-minimal-pie-chart` (2kB gzipped, zero dependencies, SVG-based) over Recharts (40kB+). GearBox only needs pie/donut -- no line charts, bar charts, etc.
+- Setup detail view: Donut chart showing weight by category, with center text showing total base weight
+- Optional toggle: switch between "by category" and "by classification" views
+- Color assignment: Derive from category or classification type (base = neutral gray, worn = blue, consumable = amber)
+- Hover tooltips showing category name, weight, and percentage
+- Responsive: Chart should work on mobile viewports
+
+**Complexity:** MEDIUM. New dependency, new component, integration with totals data. The chart itself is straightforward; the data aggregation for per-setup-per-category-per-classification is the main work.
+
+### 4. Candidate Status Tracking
+
+**What users expect:** This is novel -- no competitor has it. The workflow mirrors real purchase behavior:
+1. **Researching** (default): You found this product, added it to a thread, and are evaluating it
+2. **Ordered**: You decided to buy it and placed an order
+3. **Arrived**: The product has been delivered. Ready for thread resolution.
+
+**Why this matters:** Without status tracking, threads are a flat list of candidates. With it, threads become a living purchase tracker. A user can see at a glance "I ordered the Nemo Tensor, still researching two other pads."
+
+**Recommended implementation:**
+- Add `status TEXT NOT NULL DEFAULT 'researching'` column to `thread_candidates` table
+- Valid values: `"researching"`, `"ordered"`, `"arrived"`
+- UI: Status badge on CandidateCard (small colored pill, similar to existing weight/price badges)
+- Color scheme: researching = gray/neutral, ordered = amber/yellow, arrived = green
+- Status change: Dropdown or simple click-to-cycle on the candidate card
+- Thread-level summary: Show count by status ("2 researching, 1 ordered")
+- When resolving a thread, only candidates with status "arrived" should be selectable as winners (soft constraint -- show a warning, not a hard block, since users may resolve with a "researching" candidate they just bought in-store)
+
+**Complexity:** LOW. Simple column addition, enum-like text field, badge rendering, optional status transition UI.
+
+### 5. Weight Unit Selection
+
+**What users expect:** Choose a preferred unit (grams, ounces, pounds, kilograms) and have ALL weight displays in the app use that unit. LighterPack toggles between g/oz/lb/kg at the top level. The BPL Calculator app lets you "enter item weights in grams and switch the entire display to lbs & oz."
+
+**Domain patterns observed:**
+- LighterPack: Toggle at list level between lb/oz/g/kg. Only changes summary display, not per-item display.
+- Packrat: "Input items in different units, choose how they're displayed, and freely convert between them."
+- BPL Calculator: Global settings change, applied to all displays
+- WeighMyGear: Input locked to grams, less intuitive
+
+**Recommended implementation:**
+- Store preference in existing `settings` table as `{ key: "weightUnit", value: "g" }` (default: grams)
+- Supported units: `g` (grams), `oz` (ounces), `lb` (pounds + ounces), `kg` (kilograms)
+- Conversion constants: 1 oz = 28.3495g, 1 lb = 453.592g, 1 kg = 1000g
+- Display format per unit:
+  - `g`: "450g" (round to integer)
+  - `oz`: "15.9 oz" (one decimal)
+  - `lb`: "2 lb 3 oz" (pounds + remainder ounces, traditional format)
+  - `kg`: "1.45 kg" (two decimals)
+- Update `formatWeight()` to accept unit parameter or read from a React context/hook
+- Settings UI: Simple dropdown or segmented control, accessible from a settings page or inline in the TotalsBar
+- Internal storage stays as grams (already the case with `weight_grams` column)
+- Affects: TotalsBar, ItemCard, CandidateCard, SetupCard, CategoryHeader, setup detail view, chart tooltips
+
+**Complexity:** LOW. No schema changes. Update the `formatWeight()` function, add a settings hook, propagate the unit to all display points. The main effort is touching every component that displays weight (there are ~6-8 call sites).
+
+### 6. Planning Category Filter with Icon-Aware Dropdown
+
+**What users expect:** The existing category filter in PlanningView is a plain `<select>` without icons. Since categories now have Lucide icons (v1.1), the filter should show them.
+
+**Recommended implementation:**
+- Replace the native `<select>` with a custom dropdown component that renders `<LucideIcon>` alongside category names
+- Match the visual style of the CategoryPicker used in thread creation
+- Same functionality, better visual consistency
+
+**Complexity:** LOW. UI-only change. Replace ~20 lines of `<select>` with a custom dropdown component.
+

+# Pitfalls Research
+
+**Domain:** Adding search/filter, weight classification, weight distribution charts, candidate status tracking, and weight unit selection to an existing gear management app (GearBox v1.2)
+**Researched:** 2026-03-16
+**Confidence:** HIGH (pitfalls derived from direct codebase analysis + domain-specific patterns from gear tracking community + React/SQLite ecosystem knowledge)
+
+## Critical Pitfalls
+
+### Pitfall 1: Weight Unit Conversion Rounding Accumulation
+
+**What goes wrong:**
+GearBox stores weight as `real("weight_grams")` (a floating-point column in SQLite). When adding unit selection (g, oz, lb, kg), the naive approach is to convert on display and let users input in their preferred unit, converting back to grams on save. The problem: repeated round-trip conversions accumulate rounding errors. A user enters `5.3 oz`, which converts to `150.253...g`, gets stored as `150.253`, then displayed back as `5.30 oz` (fine so far). But if the user opens the edit form (which shows `5.30 oz`), makes no changes, and saves, the value reconverts from the displayed `5.30` to `150.2535g` -- a different value from what was stored. Over multiple edit cycles, weights drift. More critically, the existing `SUM(items.weight_grams)` aggregates in `setup.service.ts` and `totals.service.ts` will accumulate these micro-errors across dozens of items, producing totals that visibly disagree with manual addition of displayed values. A setup showing items of "5.3 oz + 2.1 oz" but a total of "7.41 oz" (instead of 7.40 oz) erodes trust in the app's core value proposition.
+
+**Why it happens:**
+The conversion factor between grams and ounces (28.3495) is irrational enough that floating-point representation always involves truncation. Combined with SQLite's `REAL` type (8-byte IEEE 754 float, ~15 digits of precision), individual items are accurate enough, but the accumulation across conversions and summation surfaces visible errors.
+
+**How to avoid:**
+1. Store weights in grams as the canonical unit -- this is already done. Good.
+2. Convert only at the display boundary (the `formatWeight` function in `lib/formatters.ts`). Never convert grams to another unit, let the user edit, and convert back.
+3. When the user inputs in oz/lb/kg, convert to grams once on save and store. The edit form should always load the stored grams value and re-convert for display, never re-convert from a previously displayed value.
+4. Round only at the final display step, not during storage. Use `Number(value.toFixed(1))` for display, never for the stored value.
+5. For totals, compute `SUM(weight_grams)` in SQL (already done), then convert the total to display units once. Do not sum converted per-item display values.
+6. Consider changing `weight_grams` from `real` to `integer` to store milligrams (or tenths of grams) for sub-gram precision without floating-point issues. This is a larger migration but eliminates the class of errors entirely.
+
+**Warning signs:**
+- Edit form pre-fills with a converted value and saves by reconverting that value
+- `formatWeight` is called before summation rather than after
+- Unit conversion is done in multiple places (client and server) with different rounding
+- Tests compare floating-point totals with `===` instead of tolerance-based comparison
+
+**Phase to address:**
+Phase 1 (Weight unit selection) -- the conversion layer must be designed correctly from the start. Getting this wrong poisons every downstream feature (charts, setup totals, classification breakdowns).
+
+---
+
+### Pitfall 2: Weight Classification Stored at Wrong Level
+
+**What goes wrong:**
+Weight classification (base weight / worn / consumable) seems like a property of the item itself -- "my rain jacket is always worn weight." So the developer adds a `classification` column to the `items` table. But this is wrong: the same item can be classified differently in different setups. A rain jacket is "worn" in a summer bikepacking setup but "base weight" (packed in the bag) in a winter setup where you wear a heavier outer shell. By putting classification on the item, users cannot accurately model multiple setups with the same gear, which is the entire point of the setup feature.
+
+**Why it happens:**
+LighterPack and similar tools model classification at the list level (each list has its own classification per item), but when you look at the GearBox schema, the `setup_items` join table only has `(id, setup_id, item_id)`. It feels more natural to add a column to the item itself rather than to a join table, especially since the current `setup_items` table is minimal. The single-user context also makes it feel like "my items have fixed classifications."
+
+**How to avoid:**
+Add `classification TEXT DEFAULT 'base'` to the `setup_items` table, not to `items`. This means:
+- The same item can have different classifications in different setups
+- Classification is optional and defaults to "base" (the most common case)
+- The `items` table stays generic -- classification is a setup-level concern
+- Existing `setup_items` rows get a sensible default via the migration
+- SQL aggregates for setup totals can easily group by classification: `SUM(CASE WHEN setup_items.classification = 'base' THEN items.weight_grams ELSE 0 END)`
+
+If classification is also useful outside of setups (e.g., in the collection view for a general breakdown), add it as an optional `defaultClassification` on `items` that serves as a hint when adding items to setups, but the authoritative classification is always on `setup_items`.
+
+**Warning signs:**
+- `classification` column added to `items` table
+- Setup detail view shows classification but cannot be different per setup
+- Weight breakdown chart shows the same classification for an item across all setups
+- No way to classify an item as "worn" in one setup and "base" in another
+
+**Phase to address:**
+Phase 2 (Weight classification) -- this is the single most important schema decision in v1.2. Getting it wrong requires migrating data out of the `items` table into `setup_items` later, which means reconciling possibly-different classifications that users already set.
+
+---
+
+### Pitfall 3: Search/Filter Implemented Server-Side for a Client-Side Dataset
+
+**What goes wrong:**
+The developer adds a `GET /api/items?search=tent&category=3` endpoint, sending filtered results from the server. This means:
+- Every keystroke fires an API request (or requires debouncing, adding latency)
+- The client's React Query cache for `["items"]` now contains different data depending on filter params, causing stale/inconsistent state
+- Category grouping in `CollectionView` breaks because the full list is no longer available
+- The existing `useTotals()` hook returns totals for all items, but the list shows filtered items -- a confusing mismatch
+
+**Why it happens:**
+Server-side filtering is the "correct" pattern at scale, and most tutorials teach it that way. But GearBox is a single-user app where the entire collection fits comfortably in memory. The existing `useItems()` hook already fetches all items in one call and the collection view groups them client-side.
+
+**How to avoid:**
+Implement search and filter entirely on the client side:
+1. Keep `useItems()` fetching the full list (it already does)
+2. Add filter state (search query, category ID) as URL search params or React state in the collection page
+3. Filter the `items` array in the component using `Array.filter()` before grouping and rendering
+4. The totals bar should continue to show collection totals (unfiltered), not filtered totals -- or show both ("showing 12 of 47 items")
+5. Only move to server-side filtering if the collection exceeds ~500 items, which is far beyond typical for a single-user gear app
+
+This preserves the existing caching behavior, requires zero API changes, and gives instant feedback on every keystroke.
+
+**Warning signs:**
+- New query parameters added to `GET /api/items` endpoint
+- `useItems` hook accepts filter params, creating multiple cache entries
+- Search input has a debounce delay
+- Filtered view totals disagree with dashboard totals
+
+**Phase to address:**
+Phase 1 (Search/filter) -- the decision to filter client-side vs server-side affects where state lives and must be decided before building the UI.
+
+---
+
+### Pitfall 4: Candidate Status Transition Without Validation
+
+**What goes wrong:**
+The existing thread system has a simple `status: "active" | "resolved"` on threads and no status on candidates. Adding candidate status tracking (researching -> ordered -> arrived) as a simple text column without transition validation allows impossible states: a candidate marked "arrived" in a thread that was already "resolved," or a candidate going from "arrived" back to "researching." Worse, the existing `resolveThread` function in `thread.service.ts` copies candidate data to create a collection item -- but does not check or update candidate status, so a "researching" candidate can be resolved as the winner (logically wrong, though the data flow works).
+
+**Why it happens:**
+The current codebase uses plain strings for thread status with no validation layer. The developer follows the same pattern for candidate status: just a text column with no constraints. SQLite does not enforce enum values, so any string is accepted.
+
+**How to avoid:**
+1. Define valid candidate statuses as a union type: `"researching" | "ordered" | "arrived"` in `schemas.ts`
+2. Add Zod validation for the status field with `.refine()` or `z.enum()` to reject invalid values at the API level
+3. Define valid transitions: `researching -> ordered -> arrived` (and optionally `* -> dropped`)
+4. In the service layer, validate that the requested status transition is valid before applying it (e.g., cannot go from "arrived" to "researching")
+5. When resolving a thread, do NOT require a specific candidate status -- the user may resolve with a "researching" candidate if they decide to buy it outright. But DO update all non-winner candidates to a terminal state like "dropped" in the same transaction.
+6. Add a check in `resolveThread`: if the thread is already resolved, reject the operation (this check already exists in the current code -- good)
+
+**Warning signs:**
+- Candidate status is a plain `text()` column with no Zod enum validation
+- No transition validation in the update candidate service
+- `resolveThread` does not update non-winner candidate statuses
+- UI allows arbitrary status changes via a dropdown with no constraints
+
+**Phase to address:**
+Phase 3 (Candidate status tracking) -- must be designed with awareness of the existing thread resolution flow in `thread.service.ts`. The status field and transition logic should be added together, not incrementally.
+
+---
+
+### Pitfall 5: Weight Distribution Chart Diverges from Displayed Totals
+
+**What goes wrong:**
+The weight distribution chart (e.g., a donut chart showing weight by category or by classification) computes its data from one source, while the totals bar and setup detail page compute from another. The chart might use client-side summation of displayed (rounded) values while the totals use SQL `SUM()`. Or the chart uses the `useTotals()` hook data while the setup page computes totals inline (as `$setupId.tsx` currently does on lines 53-61). These different computation paths produce different numbers for the same data, and when a chart slice says "Shelter: 2,450g" but the category header says "Shelter: 2,451g," users lose trust.
+
+**Why it happens:**
+The codebase already has two computation paths for totals: `totals.service.ts` computes via SQL aggregates, and the setup detail page computes via JavaScript reduce on the client. These happen to agree now because there is no unit conversion, but adding unit display and classification filtering creates more opportunities for divergence.
+
+**How to avoid:**
+1. Establish a single source of truth for all weight computations: the SQL aggregate in the service layer.
+2. For chart data, create a dedicated endpoint or extend `GET /api/totals` to return breakdowns by category AND by classification (for setups). Do not recompute in the chart component.
+3. For setup-specific charts, extend `getSetupWithItems` to return pre-computed breakdowns, or compute them from the setup's item list using a shared utility function that is used by both the totals display and the chart.
+4. Unit conversion happens once, at the display layer, using the same `formatWeight` function everywhere.
+5. Write a test that compares the chart data source against the totals data source and asserts they agree.
+
+**Warning signs:**
+- Chart component does its own `reduce()` on item data instead of using the same data as the totals display
+- Two different API endpoints return weight totals for the same scope and the values differ by small amounts
+- Chart labels show different precision than text displays (chart: "2.4 kg", header: "2,451 g")
+- No shared utility function for weight summation
+
+**Phase to address:**
+Phase 3 (Weight distribution visualization) -- but the single-source-of-truth pattern should be established in Phase 1 when refactoring formatters for unit selection.
+
+---
+
+### Pitfall 6: Schema Migration Breaks Test Helper
+
+**What goes wrong:**
+GearBox's test infrastructure uses a manual `createTestDb()` function in `tests/helpers/db.ts` that creates tables with raw SQL `CREATE TABLE` statements instead of using Drizzle's migration system. When adding new columns (e.g., `classification` to `setup_items`, `status` to `thread_candidates`, `weight_unit` to `settings`), the developer updates `src/db/schema.ts` and runs `bun run db:generate` + `bun run db:push`, but forgets to update the test helper's CREATE TABLE statements. All tests pass in the test database (which has the old schema) while the real database has the new schema -- or worse, tests fail with cryptic column-not-found errors and the developer wastes time debugging the wrong thing.
+
+**Why it happens:**
+The test helper duplicates the schema definition in raw SQL rather than deriving it from the Drizzle schema. This is a known pattern in the codebase (documented in CLAUDE.md: "When adding schema columns, update both `src/db/schema.ts` and the test helper's CREATE TABLE statements"). But under the pressure of adding multiple schema changes across several features, it is easy to miss one table or one column.
+
+**How to avoid:**
+1. **Every schema change PR must include the corresponding test helper update.** Add this as a checklist item in the development workflow.
+2. Consider writing a simple validation test that compares the columns in `createTestDb()` tables against the Drizzle schema definition, failing if they diverge. This catches the problem automatically.
+3. For v1.2, since multiple schema changes are landing (classification on setup_items, status on candidates, possibly weight_unit in settings), batch the test helper update and verify all changes in one pass.
+4. Long-term: investigate using Drizzle's `migrate()` with in-memory SQLite to eliminate the duplication entirely.
+
+**Warning signs:**
+- Schema column added to `schema.ts` but not to `tests/helpers/db.ts`
+- Tests pass locally but queries fail at runtime
+- New service function works in the app but throws in tests
+- Test database has fewer columns than production database
+
+**Phase to address:**
+Every phase that touches the schema. Must be addressed in Phase 1 (unit settings), Phase 2 (classification on setup_items), and Phase 3 (candidate status). Each phase should verify test helper parity as a completion criterion.
+
+---
+
+### Pitfall 7: Weight Unit Preference Stored Wrong, Applied Wrong
+
+**What goes wrong:**
+The developer stores the user's preferred weight unit as a setting (using the existing `settings` table with key-value pairs). But then applies it inconsistently: the collection page shows grams, the setup page shows ounces, the chart shows kilograms. Or the setting is read once on page load and cached in Zustand, so changing the preference requires a page refresh. Or the setting is read on every render, causing a flash of "g" before the "oz" preference loads.
+
+**Why it happens:**
+The `settings` table is a key-value store with no type safety. The preference is a string like `"oz"` that must be parsed and applied in many places: `formatWeight` in formatters, chart labels, totals bar, setup detail, item cards, category headers. Missing any one of these locations creates an inconsistency.
+
+**How to avoid:**
+1. Store the preference in the `settings` table as `{ key: "weightUnit", value: "g" | "oz" | "lb" | "kg" }`.
+2. Create a `useWeightUnit()` hook that wraps `useSettings()` and returns the parsed unit with a fallback to `"g"`.
+3. Modify `formatWeight` to accept a unit parameter: `formatWeight(grams, unit)`. This is a single function used everywhere, so changing it propagates automatically.
+4. Do NOT store converted values anywhere -- always store grams, convert at display time.
+5. Use React Query for the settings fetch so the preference is cached and shared across components. When the user changes their preference, invalidate `["settings"]` and all displays update simultaneously via React Query's reactivity.
+6. Handle the loading state: show raw grams (or a loading skeleton) until the preference is loaded. Do not flash a different unit.
+
+**Warning signs:**
+- `formatWeight` does not accept a unit parameter -- it is hardcoded to `"g"`
+- Weight unit preference is stored in Zustand instead of React Query (settings endpoint)
+- Some components use `formatWeight` and some inline their own formatting
+- Changing the unit preference does not update all visible weights without a page refresh
+
+**Phase to address:**
+Phase 1 (Weight unit selection) -- this is foundational infrastructure. The `formatWeight` refactor and `useWeightUnit` hook must exist before building any other feature that displays weight.
+
+---
+
+## Technical Debt Patterns
+
+Shortcuts that seem reasonable but create long-term problems.
+
+| Shortcut | Immediate Benefit | Long-term Cost | When Acceptable |
+|----------|-------------------|----------------|-----------------|
+| Adding classification to `items` instead of `setup_items` | Simpler schema, no join table changes | Cannot have different classifications per setup; future migration required | Never -- the per-setup model is the correct one |
+| Client-side unit conversion on both read and write paths | Simple bidirectional conversion | Rounding drift over edit cycles, inconsistent totals | Never -- convert once on write, display-only on read |
+| Separate chart data computation from totals computation | Faster chart development, no API changes | Numbers disagree between chart and text displays | Only if a shared utility function ensures identical computation |
+| Hardcoding chart library colors per category | Quick to implement | Colors collide when user adds categories; no dark mode support | MVP only if using a predictable color generation function is planned |
+| Adding candidate status without transition validation | Faster to implement | Invalid states accumulate, resolve logic has edge cases | Only if validation is added before the feature ships to production |
+| Debouncing search instead of client-side filter | Familiar pattern from server-filtered apps | Unnecessary latency, complex cache management | Never for this app's scale (sub-500 items) |
+
+## Integration Gotchas
+
+Since v1.2 is adding features to an existing system rather than integrating external services, these are internal integration points where new features interact with existing ones.
+
+| Integration Point | Common Mistake | Correct Approach |
+|-------------------|----------------|------------------|
+| Search/filter + category grouping | Filtering items breaks the existing category-grouped layout because the group headers disappear when no items match | Filter within groups: show category headers only for groups with matching items. Empty groups should hide, not show "no items." |
+| Weight classification + existing setup totals | Adding classification changes how totals are computed (base weight vs total weight), but existing setup list cards show `totalWeight` which was previously "everything" | Keep `totalWeight` as the sum of all items. Add `baseWeight` as a new computed field (sum of items where classification = 'base'). Show both in the setup detail view. |
+| Candidate status + thread resolution | Adding status to candidates but not updating `resolveThread` to handle it | The `resolveThread` transaction must set winner status to a terminal state and non-winners to "dropped." New candidates added to an already-resolved thread should be rejected. |
+| Unit selection + React Query cache | Changing the weight unit preference does not invalidate the items cache because items are stored in grams regardless | The unit preference is a display concern, not a data concern. Do NOT invalidate items/totals on unit change. Just re-render with the new unit. Ensure `formatWeight` is called reactively, not cached. |
+| Weight chart + empty/null weights | Chart component crashes or shows misleading data when items have `null` weight | Filter out items with null weight from chart data. Show a note like "3 items excluded (no weight recorded)." Never treat null as 0 in a chart -- that makes the chart lie. |
+
+## Performance Traps
+
+Patterns that work at small scale but fail as usage grows.
+
+| Trap | Symptoms | Prevention | When It Breaks |
+|------|----------|------------|----------------|
+| Re-rendering entire collection on search keystroke | UI jank on every character typed in search box | Use `useMemo` to memoize the filtered list; ensure `ItemCard` is memoized with `React.memo` | 100+ items with images |
+| Chart re-renders on every parent state change | Chart animation restarts on unrelated state updates (e.g., opening a panel) | Memoize chart data computation with `useMemo`; wrap chart component in `React.memo`; use `isAnimationActive={false}` after initial render | Any chart library with entrance animations |
+| Recharts SVG rendering with many category slices | Donut chart becomes sluggish with 20+ categories, each with a tooltip and label | Limit chart to top N categories by weight, group the rest into "Other." Recharts is SVG-based, so keep segments under ~15. | 20+ categories (unlikely for single user, but possible) |
+| Fetching settings on every component that displays weight | Waterfall of settings requests, or flash of unconverted weights | Use React Query with `staleTime: Infinity` for settings (they change rarely). Prefetch settings at app root. | First load of any page with weights |
+| Computing classification breakdown per-render | Expensive reduce operations on every render cycle | Compute once in `useMemo` keyed on the items array and classification data | Setups with 50+ items (common for full bikepacking lists) |
+
+## Security Mistakes
+
+Domain-specific security issues beyond general web security.
+
+| Mistake | Risk | Prevention |
+|---------|------|------------|
+| Candidate status field accepts arbitrary strings | SQLite text column accepts anything; UI may display unexpected values or XSS payloads in status badges | Validate status against enum in Zod schema. Reject unknown values at API level. Use `z.enum(["researching", "ordered", "arrived"])`. |
+| Search query used in raw SQL LIKE | SQL injection if search string is interpolated into query (unlikely with Drizzle ORM but possible in raw SQL aggregates) | Use Drizzle's `like()` or `ilike()` operators which parameterize automatically. Never use template literals in `sql\`\`` with unsanitized user input. |
+| Unit preference allows arbitrary values | Settings table stores any string; a crafted value could break formatWeight or cause display issues | Validate unit against `z.enum(["g", "oz", "lb", "kg"])` both on read and write. Use a typed constant for the allowed values. |
+
+## UX Pitfalls
+
+Common user experience mistakes in this domain.
+
+| Pitfall | User Impact | Better Approach |
+|---------|-------------|-----------------|
+| Search clears when switching tabs (gear/planning/setups) | User searches for "tent," switches to planning to check threads, switches back and search is gone | Persist search query as a URL search parameter (`?tab=gear&q=tent`). TanStack Router already handles tab via search params. |
+| Unit selection buried in settings page | User cannot quickly toggle between g and oz when comparing products listed in different units | Add a unit toggle/selector directly in the weight display area (e.g., in the TotalsBar or a small dropdown next to weight values). Keep global preference in settings, but allow quick access. |
+| Classification picker adds friction to setup composition | User must classify every item when adding it to a setup, turning a quick "add to loadout" into a tedious process | Default all items to "base" classification. Allow bulk reclassification. Show classification as an optional second step after composing the setup. |
+| Chart with no actionable insight | A pie chart showing "Shelter: 40%, Sleep: 25%, Cooking: 20%" is pretty but does not help the user make decisions | Pair the chart with a list sorted by weight. Highlight the heaviest category. If possible, show how the breakdown compares to "typical" or to other setups. At minimum, make chart segments clickable to filter to that category. |
+| Status badges with no timestamps | User sees "ordered" but cannot remember when they ordered, or whether it has been suspiciously long | Store status change timestamps. Show relative time ("ordered 3 days ago"). Highlight statuses that have been stale too long ("ordered 30+ days ago -- still waiting?"). |
+| Filter resets feel destructive | User applies multiple filters (category + search), then accidentally clears one and loses the other | Show active filters as dismissible chips/pills above the list. Each filter is independently clearable. A "clear all" button resets everything. |
+
+## "Looks Done But Isn't" Checklist
+
+Things that appear complete but are missing critical pieces.
+
+- [ ] **Search/filter:** Often missing keyboard shortcut (Cmd/Ctrl+K to focus search) -- verify search is easily accessible without mouse
+- [ ] **Search/filter:** Often missing empty state for "no results" -- verify a helpful message appears when search matches nothing, distinct from "collection is empty"
+- [ ] **Weight classification:** Often missing the per-setup model -- verify the same item can have different classifications in different setups
+- [ ] **Weight classification:** Often missing "unclassified" handling -- verify items with no classification default to "base" in all computations
+- [ ] **Weight chart:** Often missing null-weight items -- verify items without weight data are excluded from chart with a visible note, not silently treated as 0g
+- [ ] **Weight chart:** Often missing responsiveness -- verify chart renders correctly on mobile widths (Recharts needs `ResponsiveContainer` wrapper)
+- [ ] **Candidate status:** Often missing transition validation -- verify a candidate cannot go from "arrived" back to "researching"
+- [ ] **Candidate status:** Often missing integration with thread resolution -- verify resolving a thread updates all candidate statuses appropriately
+- [ ] **Unit selection:** Often missing consistent application -- verify every weight display in the app (cards, headers, totals, charts, setup detail, item picker) uses the selected unit
+- [ ] **Unit selection:** Often missing the edit form -- verify the item/candidate edit form shows weight in the selected unit and converts correctly on save
+- [ ] **Unit selection:** Often missing chart axis labels -- verify the chart shows the correct unit in labels and tooltips
+
+## Recovery Strategies
+
+When pitfalls occur despite prevention, how to recover.
+
+| Pitfall | Recovery Cost | Recovery Steps |
+|---------|---------------|----------------|
+| Classification on items instead of setup_items | HIGH | Add classification column to setup_items. Write migration to copy item classification to all setup_item rows referencing it. Remove classification from items. Review all service queries. |
+| Rounding drift from bidirectional conversion | MEDIUM | Audit all items for drift (compare stored grams to expected values). Fix formatWeight to convert only at display. One-time data cleanup for items with suspicious fractional grams. |
+| Chart data disagrees with totals | LOW | Refactor chart to use the same data source as totals. Create shared utility. No data migration needed. |
+| Test helper out of sync with schema | LOW | Update CREATE TABLE statements in test helper. Run all tests. Fix any that relied on the old schema. |
+| Server-side search causing cache issues | MEDIUM | Revert to client-side filtering. Remove query params from useItems. May need to clear stale React Query cache entries with different keys. |
+| Candidate status without transitions | MEDIUM | Add transition validation to update endpoint. Audit existing candidates for invalid states. Write cleanup migration if needed. |
+| Unit preference inconsistently applied | LOW | Audit all weight display points. Ensure all use formatWeight with unit parameter. No data changes needed. |
+
+## Pitfall-to-Phase Mapping
+
+How roadmap phases should address these pitfalls.
+
+| Pitfall | Prevention Phase | Verification |
+|---------|------------------|--------------|
+| Rounding accumulation | Phase 1: Weight unit selection | `formatWeight` converts grams to display unit. Edit forms load grams from API, not from displayed value. Write test: edit an item 10 times without changes, weight stays identical. |
+| Classification at wrong level | Phase 2: Weight classification | `classification` column exists on `setup_items`, not `items`. Test: same item in two setups has different classifications. |
+| Server-side search for client data | Phase 1: Search/filter | No new API parameters on `GET /api/items`. Filter logic lives in `CollectionView` component. Test: search works instantly without network requests. |
+| Status without transition validation | Phase 3: Candidate status | Zod enum validates status values. Service rejects invalid transitions. Test: updating "arrived" to "researching" returns 400 error. |
+| Chart/totals divergence | Phase 3: Weight visualization | Chart data and totals bar use same computation path. Test: sum of chart segment values equals displayed total. |
+| Test helper desync | Every schema-changing phase | Each phase's PR includes updated test helper. CI test suite catches column mismatches. |
+| Unit preference inconsistency | Phase 1: Weight unit selection | All weight displays use `formatWeight(grams, unit)`. Test: change unit preference, verify all visible weights update without refresh. |

+# Technology Stack -- v1.2 Collection Power-Ups
+
+**Project:** GearBox
+**Researched:** 2026-03-16
+**Scope:** Stack additions for search/filter, weight classification, weight distribution charts, candidate status tracking, weight unit selection
+**Confidence:** HIGH
+
+## Key Finding: Minimal New Dependencies
+
+Four of five v1.2 features require **zero new libraries**. They are pure application logic built on top of the existing stack (Drizzle ORM filters, Zod schema extensions, Zustand state, React Query invalidation). The only decision point is whether to add a charting library for weight distribution visualization.
+
+## New Dependency
+
+### Charting: react-minimal-pie-chart
+
+| Technology | Version | Purpose | Why |
+|------------|---------|---------|-----|
+| react-minimal-pie-chart | ^9.1.2 | Weight distribution donut/pie charts | Under 2kB gzipped. Supports pie, donut, loading, and completion chart types. SVG-based with CSS animations, hover/click interactions, custom label rendering. React 19 compatible (peerDeps explicitly include `^19`). Zero external dependencies. TypeScript native. |
+
+**Why this over alternatives:**
+
+| Criterion | react-minimal-pie-chart | Recharts | Custom SVG | Chart.js |
+|-----------|------------------------|----------|------------|----------|
+| Bundle size | ~2kB gzipped | ~97kB gzipped | 0kB | ~60kB gzipped |
+| Chart types needed | Pie + donut (exactly what we need) | Overkill (line, bar, area, scatter, etc.) | Manual math | Overkill |
+| React 19 support | Explicit in peerDeps | Isolated rendering issues reported with 19.2.x | N/A | Wrapper has open React 19 issues |
+| Interactivity | Click, hover, focus, keyboard events per segment | Full but heavy | Must implement from scratch | Canvas-based (harder to style) |
+| Labels | Render prop for custom labels (percentage, value, SVG) | Built-in | Must implement | Built-in |
+| Animation | CSS-based, configurable duration/easing, reveal effect | D3-based, heavier | Must implement | Canvas animation |
+| Learning curve | Minimal -- one component, straightforward props | Moderate -- many components | High -- SVG arc math | Moderate |
+| Maintenance risk | Low -- tiny surface area, stable API | Low -- large community | Zero | Medium -- Canvas abstraction |
+
+**Why not custom SVG:** The SVG `<circle>` + `stroke-dasharray` approach works for static charts but breaks interactivity (stacked circles mean only the last segment is clickable). The `<path>` arc approach gives full interactivity but requires implementing arc math, animation, labels, hover states, and accessibility from scratch. At ~2kB, react-minimal-pie-chart costs less than the custom code would and handles all edge cases.
+
+**Why not Recharts:** GearBox needs exactly one chart type (donut/pie). Recharts adds ~97kB of unused capability. It also had isolated rendering issues reported with React 19.2.x, and pulls in D3 submodules. Significant overkill for this use case.
+
+## Existing Stack Usage for Each Feature
+
+### 1. Search/Filter Items
+
+**No new dependencies.** Uses existing Drizzle ORM operators and React state.
+
+| Existing Tech | How It Is Used |
+|---------------|----------------|
+| Drizzle ORM `like()` | Server-side text search on `items.name` column. SQLite LIKE is case-insensitive by default, so no need for `ilike()`. |
+| Drizzle ORM `eq()`, `and()` | Category filter: `eq(items.categoryId, selectedId)`. Combine with search: `and(like(...), eq(...))`. |
+| TanStack Query | New query key pattern: `["items", { search, categoryId }]` for filtered results. Server-side filtering preferred over client-side to establish the pattern early (collections grow). |
+| Zustand or URL search params | Store active filter state. URL search params preferred (already used for tab state) so filter state is shareable/bookmarkable. |
+| Zod | Validate query params on the Hono route: `z.object({ search: z.string().optional(), categoryId: z.number().optional() })`. |
+
+**Implementation approach:** Add query parameters to `GET /api/items` rather than client-side filtering. Drizzle's conditional filter pattern handles optional params cleanly:
+
+```typescript
+import { like, eq, and } from "drizzle-orm";
+
+const conditions = [];
+if (search) conditions.push(like(items.name, `%${search}%`));
+if (categoryId) conditions.push(eq(items.categoryId, categoryId));
+
+db.select().from(items).where(and(...conditions));
+```
+
+### 2. Weight Classification (Base/Worn/Consumable)
+
+**No new dependencies.** Schema change + UI state.
+
+| Existing Tech | How It Is Used |
+|---------------|----------------|
+| Drizzle ORM | Add `weightClass` column to `setup_items` table: `text("weight_class").notNull().default("base")`. Classification is per-setup-item, not per-item globally (a sleeping bag is "base" in a bikepacking setup but might be categorized differently elsewhere). |
+| Zod | Extend `syncSetupItemsSchema` to include classification: `z.enum(["base", "worn", "consumable"])`. |
+| drizzle-kit | Generate migration for the new column: `bun run db:generate`. |
+| SQL aggregates | Compute base/worn/consumable weight subtotals server-side, same pattern as existing category totals in `useTotals`. |
+
+**Key design decision:** Weight classification belongs on `setup_items` (the join table), not on `items` directly. An item's classification depends on context -- hiking poles are "worn" if you always use them, "base" if they pitch your tent. LighterPack follows this same model. This means the `syncSetupItemsSchema` changes from `{ itemIds: number[] }` to `{ items: Array<{ itemId: number, weightClass: "base" | "worn" | "consumable" }> }`.
+
+### 3. Weight Distribution Charts
+
+**One new dependency:** `react-minimal-pie-chart` (documented above).
+
+| Existing Tech | How It Is Used |
+|---------------|----------------|
+| TanStack Query (`useTotals`) | Already returns per-category weight totals. Extend to also return per-weight-class totals for a given setup. |
+| Tailwind CSS | Style chart container, legend, responsive layout. Chart labels use Tailwind color tokens for consistency. |
+| Lucide React | Category icons in the chart legend, consistent with existing CategoryHeader component. |
+
+**Chart data sources:**
+- **By category:** Already available from `GET /api/totals` response (`categories` array with `totalWeight` per category). No new endpoint needed.
+- **By weight classification:** New endpoint `GET /api/setups/:id/breakdown` returning `{ base: number, worn: number, consumable: number }` computed from the `weight_class` column on `setup_items`.
+
+### 4. Candidate Status Tracking
+
+**No new dependencies.** Schema change + UI update.
+
+| Existing Tech | How It Is Used |
+|---------------|----------------|
+| Drizzle ORM | Add `status` column to `thread_candidates` table: `text("status").notNull().default("researching")`. Values: `"researching"`, `"ordered"`, `"arrived"`. |
+| Zod | Add to `createCandidateSchema` and `updateCandidateSchema`: `status: z.enum(["researching", "ordered", "arrived"]).default("researching")`. |
+| Tailwind CSS | Status badge colors on CandidateCard (gray for researching, amber for ordered, green for arrived). Same badge pattern used for thread status already. |
+| Lucide React | Status icons: `search` for researching, `truck` for ordered, `check-circle` for arrived. Already in the curated icon set. |
+
+### 5. Weight Unit Selection
+
+**No new dependencies.** Settings storage + formatter change.
+
+| Existing Tech | How It Is Used |
+|---------------|----------------|
+| SQLite `settings` table | Store preferred unit: `{ key: "weightUnit", value: "g" }`. Same pattern as existing onboarding settings. |
+| React Query (`useSettings`) | Already exists. Fetch and cache the weight unit preference. |
+| `formatWeight()` in `lib/formatters.ts` | Extend to accept a unit parameter and convert from grams (the canonical storage format). |
+| Zustand (optional) | Could cache the unit preference in UI store for synchronous access in formatters. Alternatively, pass it through React context or as a parameter. |
+
+**Conversion constants (stored weights are always grams):**
+
+| Unit | From Grams | Display Format |
+|------|-----------|----------------|
+| g (grams) | `x` | `${Math.round(x)}g` |
+| oz (ounces) | `x / 28.3495` | `${(x / 28.3495).toFixed(1)}oz` |
+| lb (pounds) | `x / 453.592` | `${(x / 453.592).toFixed(2)}lb` |
+| kg (kilograms) | `x / 1000` | `${(x / 1000).toFixed(2)}kg` |
+
+**Key decision:** Store weights in grams always. Convert on display only. This avoids precision loss from repeated conversions and keeps the database canonical. The `formatWeight` function becomes the single conversion point.
+
+## Installation
+
+```bash
+# Only new dependency for v1.2
+bun add react-minimal-pie-chart
+```
+
+That is it. One package, under 2kB gzipped.
+
+## Schema Changes Summary
+
+These are the Drizzle schema modifications needed (no new tables, just column additions):
+
+| Table | Change | Migration |
+|-------|--------|-----------|
+| `setup_items` | Add `weightClass: text("weight_class").notNull().default("base")` | `bun run db:generate && bun run db:push` |
+| `thread_candidates` | Add `status: text("status").notNull().default("researching")` | `bun run db:generate && bun run db:push` |
+| `settings` | No schema change (already key-value). Insert `weightUnit` row. | Seed via service or onboarding. |
+
+## What NOT to Add
+
+| Avoid | Why | Use Instead |
+|-------|-----|-------------|
+| Recharts | 97kB for one chart type. React 19 edge-case issues. D3 dependency chain. | react-minimal-pie-chart (2kB) |
+| Chart.js / react-chartjs-2 | Canvas-based (harder to style with Tailwind). Open React 19 peer dep issues. Overkill. | react-minimal-pie-chart |
+| visx | Low-level D3 primitives. Steep learning curve. Have to build chart from scratch. Great for custom viz, overkill for a donut chart. | react-minimal-pie-chart |
+| Fuse.js or similar search library | Client-side fuzzy search adds bundle weight and complexity. SQLite LIKE is sufficient for name search on a single-user collection (hundreds of items, not millions). | Drizzle `like()` operator |
+| Full-text search (FTS5) | SQLite FTS5 is powerful but requires virtual tables and different query syntax. Overkill for simple name matching on small collections. | Drizzle `like()` operator |
+| i18n library for unit conversion | This is not internationalization. It is four conversion constants and a formatter function. A library would be absurd. | Custom `formatWeight()` function |
+| State machine library (XState) | Candidate status is a simple enum, not a complex state machine. Three values with no guards or side effects. | Zod enum + Drizzle text column |
+| New Zustand store for filters | Filter state should live in URL search params for shareability/bookmarkability. The collection page already uses this pattern for tabs. | TanStack Router search params |
+
+## Existing Stack Version Compatibility
+
+All existing dependencies remain unchanged. The only version consideration:
+
+| New Package | Compatible With | Verified |
+|-------------|-----------------|----------|
+| react-minimal-pie-chart ^9.1.2 | React 19 (`peerDeps: "^16.8.0 \|\| ^17 \|\| ^18 \|\| ^19"`) | YES -- package.json on GitHub confirms. Dev deps test against React 19.0.0. |
+| react-minimal-pie-chart ^9.1.2 | TypeScript 5.x | YES -- library is TypeScript native (built with TS 3.8+). |
+| react-minimal-pie-chart ^9.1.2 | Bun bundler / Vite | YES -- pure ESM, no native dependencies, standard npm package. |

+# Project Research Summary
+
+**Project:** GearBox v1.2 -- Collection Power-Ups
+**Domain:** Gear management (bikepacking, sim racing, etc.) -- feature enhancement milestone
+**Researched:** 2026-03-16
+**Confidence:** HIGH
+
+## Executive Summary
+
+GearBox v1.2 adds six features to the existing gear management app: item search/filter, weight classification (base/worn/consumable), weight distribution charts, candidate status tracking, weight unit selection, and a planning category filter upgrade. Research confirms that four of six features require zero new dependencies -- they are pure application logic built on the existing stack (Drizzle ORM, React Query, Zod, Tailwind). The sole new dependency is `react-minimal-pie-chart` (~2kB gzipped) for donut chart visualization. The codebase is well-positioned for these additions: the settings table already supports key-value preferences, the `setup_items` join table is the correct place for weight classification, and the client-side data model is small enough for in-memory filtering.
+
+The recommended approach is to build weight unit selection first because it refactors the `formatWeight` function that every subsequent feature depends on for display. Search/filter and candidate status tracking are independent and low-risk. Weight classification is the most architecturally significant change -- it adds a column to the `setup_items` join table and changes the sync API shape from `{ itemIds: number[] }` to `{ items: Array<{ itemId, weightClass }> }`. Weight distribution charts come last because they depend on both the unit formatter and the classification data. The two schema changes (columns on `setup_items` and `thread_candidates`) should be batched into a single Drizzle migration.
+
+The primary risks are: (1) weight unit conversion rounding drift from bidirectional conversion in edit forms, (2) accidentally placing weight classification on the `items` table instead of the `setup_items` join table, and (3) chart data diverging from displayed totals due to separate computation paths. All three are preventable with clear architectural rules established in the first phase: store grams canonically, convert only at the display boundary, and use a single source of truth for weight computations.
+
+## Key Findings
+
+### Recommended Stack
+
+The existing stack (React 19, Hono, Drizzle ORM, SQLite, Bun) handles all v1.2 features without modification. One small library addition is needed.
+
+**Core technologies (all existing, no changes):**
+- **Drizzle ORM `like()`, `eq()`, `and()`**: Available for server-side filtering if needed in the future, but client-side filtering is preferred at this scale
+- **Zod `z.enum()`**: Validates weight classification (`"base" | "worn" | "consumable"`) and candidate status (`"researching" | "ordered" | "arrived"`) with compile-time type safety
+- **React Query `useSetting()`**: Reactive settings caching ensures unit preference changes propagate to all weight displays without page refresh
+- **Existing `settings` table**: Key-value store supports weight unit preference with no schema change
+
+**New dependency:**
+- **react-minimal-pie-chart ^9.1.2**: Donut/pie charts at ~2kB gzipped. React 19 compatible (explicit in peerDeps). Zero external dependencies. TypeScript native. Chosen over Recharts (~97kB, React 19 rendering issues reported) and Chart.js (~60kB, canvas-based, harder to style with Tailwind).
+
+**What NOT to add:**
+- Recharts, Chart.js, or visx (massive overkill for one chart type)
+- Fuse.js or FTS5 (overkill for name search on sub-1000 item collections)
+- XState (candidate status is a simple enum, not a complex state machine)
+- i18n library for unit conversion (four constants and a formatter function)
+
+### Expected Features
+
+**Must have (table stakes):**
+- **Search items by name** -- every competitor with an inventory has search; LighterPack notably lacks it and users complain
+- **Filter items by category** -- partially exists in planning view, missing from collection view
+- **Weight unit selection (g/oz/lb/kg)** -- universal across all competitors; gear specs come in mixed units
+- **Weight classification (base/worn/consumable)** -- pioneered by LighterPack, now industry standard; "base weight" is the core metric of the ultralight community
+
+**Should have (differentiators):**
+- **Weight distribution donut chart** -- LighterPack's pie chart is cited as its best feature; GearBox can uniquely combine category and classification breakdown
+- **Candidate status tracking (researching/ordered/arrived)** -- entirely unique to GearBox's planning thread concept; no competitor has purchase lifecycle tracking
+- **Per-setup classification** -- architecturally superior to competitors; the same item can be classified differently across setups
+
+**Defer (v2+):**
+- Per-item weight input in multiple units (parsing complexity)
+- Interactive chart drill-down (click to zoom into categories)
+- Weight goals/targets (opinionated norms conflict with hobby-agnostic design)
+- Custom weight classification labels beyond base/worn/consumable
+- Server-side full-text search (premature for single-user scale)
+- Status change timestamps on candidates (useful but not essential now)
+
+### Architecture Approach
+
+All v1.2 features integrate into the existing three-layer architecture (client/server/database) with minimal structural changes. The client layer gains 5 new files (SearchBar, WeightChart, UnitSelector components; useFormatWeight hook; migration SQL) and modifies 15 existing files. The server layer changes are limited to the setup service (weight classification PATCH endpoint, updated sync function) and thread service (candidate status field passthrough). No new route registrations are needed in `src/server/index.ts`. The API layer (`lib/api.ts`) and UI state store (`uiStore.ts`) require no changes.
+
+**Major components:**
+1. **`useFormatWeight` hook** -- single source of truth for unit-aware weight formatting; wraps `useSetting("weightUnit")` and `formatWeight(grams, unit)` so all weight displays stay consistent
+2. **`WeightChart` component** -- reusable donut chart wrapper; used in collection page (weight by category) and setup detail page (weight by classification)
+3. **`SearchBar` component** -- reusable search input with clear button; collection page filters via `useMemo` over the cached `useItems()` data
+4. **Updated `syncSetupItems`** -- breaking API change from `{ itemIds: number[] }` to `{ items: Array<{ itemId, weightClass }> }`; single call site (ItemPicker.tsx) makes this safe
+5. **`PATCH /api/setups/:id/items/:itemId`** -- new endpoint for updating weight classification without triggering full sync (which would destroy classification data)
+
+### Critical Pitfalls
+
+1. **Weight unit conversion rounding drift** -- bidirectional conversion in edit forms causes grams to drift over multiple edit cycles. Always load stored grams from the API, convert for display, and convert user input back to grams once on save. Never re-convert from a previously displayed value.
+
+2. **Weight classification at the wrong level** -- placing `classification` on the `items` table instead of `setup_items` prevents per-setup classification. A rain jacket is "worn" in summer but "base weight" in winter. This is the single most important schema decision in v1.2 and is costly to reverse.
+
+3. **Chart data diverging from displayed totals** -- the codebase already has two computation paths (SQL aggregates in `totals.service.ts` vs. JavaScript reduce in `$setupId.tsx`). Adding charts creates a third. Use a shared utility for weight summation and convert units only at the final display step.
+
+4. **Server-side search for client-side data** -- adding search API parameters creates React Query cache fragmentation and unnecessary latency. Keep filtering client-side with `useMemo` over the cached items array.
+
+5. **Test helper desync with schema** -- the manual `createTestDb()` in `tests/helpers/db.ts` duplicates schema in raw SQL. Every column addition must be mirrored there or tests pass against the wrong schema.
+
+## Implications for Roadmap
+
+Based on combined research, a 5-phase structure is recommended:
+
+### Phase 1: Weight Unit Selection
+
+**Rationale:** Foundational infrastructure. The `formatWeight` refactor touches every component that displays weight (~8 call sites). All subsequent features depend on this formatter working correctly with unit awareness. Building this first means classification totals, chart labels, and setup breakdowns automatically display in the user's preferred unit.
+
+**Delivers:** Global weight unit preference (g/oz/lb/kg) stored in settings, `useFormatWeight` hook, updated `formatWeight` function, UnitSelector component in TotalsBar, correct unit display across all existing weight surfaces (ItemCard, CandidateCard, CategoryHeader, TotalsBar, setup detail), correct unit handling in ItemForm and CandidateForm weight inputs.
+
+**Addresses:** Weight unit selection (table stakes from FEATURES.md)
+
+**Avoids:** Rounding drift (Pitfall 1), inconsistent unit application (Pitfall 7), flash of unconverted weights on load
+
+**Schema changes:** None (uses existing settings table key-value store)
+
+### Phase 2: Search, Filter, and Planning Category Filter
+
+**Rationale:** Pure client-side addition with no schema changes, no API changes, and no dependencies on other v1.2 features. Immediately useful as collections grow. The planning category filter upgrade fits naturally here since both involve filter UX and the icon-aware dropdown is a shared component.
+
+**Delivers:** Search input in collection view, icon-aware category filter dropdown (reused in gear and planning tabs), filtered item display with count ("showing 12 of 47 items"), URL search param persistence, empty state for no results, result count display.
+
+**Addresses:** Search items by name (table stakes), filter by category (table stakes), planning category filter upgrade (differentiator)
+
+**Avoids:** Server-side search anti-pattern (Pitfall 3), search state lost on tab switch (UX pitfall), category groups disappearing incorrectly during filtering
+
+**Schema changes:** None
+
+### Phase 3: Candidate Status Tracking
+
+**Rationale:** Simple schema change on `thread_candidates` with minimal integration surface. Independent of other features. Low complexity but requires awareness of the existing thread resolution flow. Schema change should be batched with Phase 4 into one Drizzle migration.
+
+**Delivers:** Status column on candidates (researching/ordered/arrived), status badge on CandidateCard with click-to-cycle, status field in CandidateForm, Zod enum validation, status transition validation in service layer (researching -> ordered -> arrived, no backward transitions).
+
+**Addresses:** Candidate status tracking (differentiator -- unique to GearBox)
+
+**Avoids:** Status without transition validation (Pitfall 4), test helper desync (Pitfall 6), not handling candidate status during thread resolution
+
+**Schema changes:** Add `status TEXT NOT NULL DEFAULT 'researching'` to `thread_candidates`
+
+### Phase 4: Weight Classification
+
+**Rationale:** Most architecturally significant change in v1.2. Changes the sync API shape (breaking change, single call site). Requires Phase 1 to be complete so classification totals display in the correct unit. Schema migration should be batched with Phase 3.
+
+**Delivers:** `weightClass` column on `setup_items`, updated sync endpoint accepting `{ items: Array<{ itemId, weightClass }> }`, new `PATCH /api/setups/:id/items/:itemId` endpoint, three-segment classification toggle per item in setup detail view, base/worn/consumable weight subtotals.
+
+**Addresses:** Weight classification base/worn/consumable (table stakes), per-setup classification (differentiator)
+
+**Avoids:** Classification on items table (Pitfall 2), test helper desync (Pitfall 6), losing classification data on sync
+
+**Schema changes:** Add `weight_class TEXT NOT NULL DEFAULT 'base'` to `setup_items`
+
+### Phase 5: Weight Distribution Charts
+
+**Rationale:** Depends on Phase 1 (unit-aware labels) and Phase 4 (classification data for setup breakdown). Only phase requiring a new npm dependency. Highest UI complexity but lowest architectural risk -- read-only visualization of existing data.
+
+**Delivers:** `react-minimal-pie-chart` integration, `WeightChart` component, collection-level donut chart (weight by category from `useTotals()`), setup-level donut chart (weight by classification), chart legend with consistent colors, hover tooltips with formatted weights.
+
+**Addresses:** Weight distribution visualization (differentiator)
+
+**Avoids:** Chart/totals divergence (Pitfall 5), chart crashing on null-weight items, unnecessary chart re-renders on unrelated state changes
+
+**Schema changes:** None (npm dependency: `bun add react-minimal-pie-chart`)
+
+### Phase Ordering Rationale
+
+- **Phase 1 first** because `formatWeight` is called by every weight-displaying component. Refactoring it after other features are built means touching the same files twice.
+- **Phase 2 is independent** and could be built in any order, but sequencing it second allows the team to ship a quick win while Phase 3/4 schema changes are designed.
+- **Batch Phase 3 + Phase 4 schema migrations** into one `bun run db:generate` run. Both add columns to existing tables; a single migration simplifies deployment.
+- **Phase 4 after Phase 1** because classification totals need the unit-aware formatter.
+- **Phase 5 last** because it is pure visualization depending on data from Phases 1 and 4, and introduces the only external dependency.
+
+### Research Flags
+
+Phases likely needing deeper research during planning:
+- **Phase 4 (Weight Classification):** The sync API shape change is breaking. The existing delete-all/re-insert pattern destroys classification data. Needs careful design of the PATCH endpoint and how ItemPicker interacts with classification preservation during item add/remove. Worth a `/gsd:research-phase`.
+- **Phase 5 (Weight Distribution Charts):** react-minimal-pie-chart API specifics (label rendering, responsive sizing, animation control) should be validated with a quick prototype. Consider a short research spike.
+
+Phases with standard patterns (skip research-phase):
+- **Phase 1 (Weight Unit Selection):** Well-documented pattern. Extend `formatWeight`, add a `useSetting` wrapper, propagate through components. No unknowns.
+- **Phase 2 (Search/Filter):** Textbook client-side filtering with `useMemo`. No API changes. Standard React pattern.
+- **Phase 3 (Candidate Status):** Simple column addition with Zod enum validation. Existing `useUpdateCandidate` mutation already handles partial updates.
+
+## Confidence Assessment
+
+| Area | Confidence | Notes |
+|------|------------|-------|
+| Stack | HIGH | Only one new dependency (react-minimal-pie-chart). React 19 compatibility verified via package.json peerDeps. All other features use existing stack with no changes. |
+| Features | HIGH | Feature set derived from analysis of 8+ competing tools (LighterPack, Hikt, PackLight, Packstack, HikeLite, Packrat, OutPack, BPL Calculator). Clear consensus on table stakes vs. differentiators. |
+| Architecture | HIGH | Based on direct codebase analysis with integration points mapped to specific files. The 5 new / 15 modified file inventory is concrete and verified against the existing codebase. |
+| Pitfalls | HIGH | Derived from codebase-specific patterns (test helper duplication, dual computation paths) combined with domain risks (unit conversion rounding, classification scope). Not generic warnings. |
+
+**Overall confidence:** HIGH
+
+### Gaps to Address
+
+- **`lb` display format:** FEATURES.md suggests "2 lb 3 oz" (pounds + remainder ounces) while STACK.md suggests simpler decimal format. The traditional "lb + oz" format is more useful to American users but adds formatting complexity. Decide during Phase 1 implementation.
+- **Status change timestamps:** PITFALLS.md recommends storing `statusChangedAt` alongside `status` for staleness detection ("ordered 30 days ago -- still waiting?"). Low effort to add during the schema migration. Decide during Phase 3 planning.
+- **Sync API backward compatibility:** The sync endpoint shape changes from `{ itemIds: number[] }` to `{ items: [...] }`. Single call site (ItemPicker.tsx), but verify no external consumers exist before shipping.
+- **react-minimal-pie-chart responsive behavior:** SVG-based and should handle responsive sizing, but exact approach (CSS width vs. explicit size prop) should be validated in Phase 5. Not a risk, just a detail to confirm.

+title: Replace planning category filter select with icon-aware dropdown
+area: ui
+files:
+  - src/client/routes/collection/index.tsx
+---
+
+## Problem
+
+The category filter in the planning tab uses a native HTML `<select>` element, which cannot render Lucide icons inline. After Phase 6 migrated all category icons from emoji to Lucide, this filter only shows category names without their icons — inconsistent with the rest of the app where category icons appear alongside names (CategoryPicker combobox, CategoryHeader, cards, etc.).
+
+This was documented as a deliberate deviation in 06-02-SUMMARY due to HTML `<select>` constraints.
+
+## Solution
+
+Replace the native `<select>` with a custom dropdown component (similar to CategoryPicker's combobox pattern) that renders `LucideIcon` + category name for each option. Reuse the existing popover/dropdown patterns from IconPicker or CategoryPicker.

+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+GearBox is a single-user web app for managing gear collections (bikepacking, sim racing, etc.), tracking weight/price, and planning purchases through research threads. Full-stack TypeScript monolith running on Bun.
+
+## Commands
+
+```bash
+# Development (run both in separate terminals)
+bun run dev:client          # Vite dev server on :5173 (proxies /api to :3000)
+bun run dev:server          # Hono server on :3000 with hot reload
+
+# Database
+bun run db:generate         # Generate Drizzle migration from schema changes
+bun run db:push             # Apply migrations to gearbox.db
+
+# Testing
+bun test                    # Run all tests
+bun test tests/services/item.service.test.ts  # Run single test file
+
+# Lint & Format
+bun run lint                # Biome check (tabs, double quotes, organized imports)
+
+# Build
+bun run build               # Vite build → dist/client/
+```
+
+## Architecture
+
+**Stack**: React 19 + Hono + Drizzle ORM + SQLite, all running on Bun.
+
+### Client (`src/client/`)
+- **Routing**: TanStack Router with file-based routes in `src/client/routes/`. Route tree auto-generated to `routeTree.gen.ts` — never edit manually.
+- **Data fetching**: TanStack React Query via custom hooks in `src/client/hooks/` (e.g., `useItems`, `useThreads`, `useSetups`). Mutations invalidate related query keys.
+- **UI state**: Zustand store (`stores/uiStore.ts`) for panel/dialog state only — server data lives in React Query.
+- **API calls**: Thin fetch wrapper in `lib/api.ts` (`apiGet`, `apiPost`, `apiPut`, `apiDelete`, `apiUpload`).
+- **Styling**: Tailwind CSS v4.
+
+### Server (`src/server/`)
+- **Routes** (`routes/`): Hono handlers with Zod validation via `@hono/zod-validator`. Delegate to services.
+- **Services** (`services/`): Pure business logic functions that take a db instance. No HTTP awareness — testable without mocking.
+- Route registration in `src/server/index.ts` via `app.route("/api/...", routes)`.
+
+### Shared (`src/shared/`)
+- **`schemas.ts`**: Zod schemas for API request validation (source of truth for types).
+- **`types.ts`**: Types inferred from Zod schemas + Drizzle table definitions. No manual type duplication.
+
+### Database (`src/db/`)
+- **Schema**: `schema.ts` — Drizzle table definitions for SQLite.
+- **Prices stored as cents** (`priceCents: integer`) to avoid float rounding.
+- **Timestamps**: stored as integers (unix epoch) with `{ mode: "timestamp" }`.
+- Tables: `categories`, `items`, `threads`, `threadCandidates`, `setups`, `setupItems`, `settings`.
+
+### Testing (`tests/`)
+- Bun test runner. Tests at service level and route level.
+- `tests/helpers/db.ts`: `createTestDb()` creates in-memory SQLite with full schema and seeds an "Uncategorized" category. When adding schema columns, update both `src/db/schema.ts` and the test helper's CREATE TABLE statements.
+
+## Path Alias
+
+`@/*` maps to `./src/*` (configured in tsconfig.json).
+
+## Key Patterns
+
+- **Thread resolution**: Resolving a thread copies the winning candidate's data into a new item in the collection, sets `resolvedCandidateId`, and changes status to "resolved".
+- **Setup item sync**: `PUT /api/setups/:id/items` replaces all setup_items atomically (delete all, re-insert).
+- **Image uploads**: `POST /api/images` saves to `./uploads/` with UUID filename, returned as `imageFilename` on item/candidate records.
+- **Aggregates** (weight/cost totals): Computed via SQL on read, not stored on records.
