 ### Out of Scope
 
 - Authentication / multi-user — single user for v1, no login needed
-- Custom comparison parameters — future enhancement, not v1
-- Mobile app — web-first
-- Social/sharing features — may add later
+- Custom comparison parameters — complexity trap, weight/price covers 80% of cases
+- Mobile native app — web-first, responsive design sufficient
+- Social/sharing features — different product, defer to v2+
+- 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
 
-- Primary use case is bikepacking gear, but the data model should be generic enough for any hobby/collection type
-- Replaces a spreadsheet-based workflow for tracking gear and planning purchases
-- Single user, no auth — simplest possible setup
-- User prefers Bun over npm as package manager/runtime

+
+## 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

 # Roadmap: GearBox
 
-## Overview
+## Milestones
 
-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.

+<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.

+  </behavior>
+  <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.

+
+    **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

+
+Purpose: Give users the full planning thread workflow in the UI -- create threads, add candidates, compare them visually, and resolve by picking a winner.

+  <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)

+  <files>src/client/routes/threads/$threadId.tsx, src/client/components/CandidateCard.tsx, src/client/components/CandidateForm.tsx, src/client/routes/__root.tsx</files>
+  <action>
+    1. **Create `src/client/components/CandidateCard.tsx`:** Card for candidates within a thread.
+       - Same visual style as ItemCard (same card shape, shadows, tag chips)
+       - Props: id, name, weightGrams, priceCents, categoryName, categoryEmoji, imageFilename, threadId
+       - Display: name, weight (formatted in g/kg), price (formatted in dollars from cents), category chip with emoji
+       - Image display if imageFilename present (use /uploads/ path)
+       - Edit button (opens candidate edit panel via uiStore)
+       - Delete button (opens confirm delete dialog via uiStore)
+       - "Pick as Winner" button -- a distinct action button (e.g. a crown/trophy icon or "Pick Winner" text button). Clicking opens the resolve confirmation dialog via `openResolveDialog(threadId, candidateId)`.
+       - Only show "Pick as Winner" when the thread is active (not resolved)
+
+    2. **Create `src/client/components/CandidateForm.tsx`:** Form for adding/editing candidates.
+       - Structurally similar to ItemForm but uses candidate hooks (useCreateCandidate, useUpdateCandidate)
+       - Same fields: name (required), weight (in grams, displayed as user-friendly input), price (in dollars, converted to cents for API), category (reuse CategoryPicker), notes, product URL, image upload (reuse ImageUpload component)
+       - mode="add": creates candidate via useCreateCandidate
+       - mode="edit": loads candidate data, updates via useUpdateCandidate
+       - On success: closes panel via closeCandidatePanel()
+       - Dollar-to-cents conversion on submit (same as ItemForm pattern)
+
+    3. **Create `src/client/routes/threads/$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.

+**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

+    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

+# 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
+- 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
+- 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)
+- Impact preview showing how a candidate affects setup weight/cost -- v2 (THRD-08)

+
+### 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

+## 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).

+### Sampling Rate
+- **Per task commit:** `bun test --bail`
+- **Per wave merge:** `bun test`
+- **Phase gate:** Full suite green before `/gsd:verify-work`
+
+### Wave 0 Gaps
+- [ ] `tests/services/thread.service.test.ts` -- covers THRD-01, THRD-02, THRD-03, THRD-04
+- [ ] `tests/routes/threads.test.ts` -- integration tests for thread API endpoints
+- [ ] `tests/helpers/db.ts` -- MODIFY: add threads + thread_candidates table creation
+
+## Sources
+
+### Primary (HIGH confidence)
+- Existing codebase: `src/db/schema.ts`, `src/server/services/item.service.ts`, `src/server/routes/items.ts` -- established patterns to replicate
+- Existing codebase: `tests/helpers/db.ts`, `tests/services/item.service.test.ts` -- test infrastructure and patterns
+- Existing codebase: `src/client/hooks/useItems.ts`, `src/client/stores/uiStore.ts` -- client-side patterns
+- Phase 1 research: `.planning/phases/01-foundation-and-collection/01-RESEARCH.md` -- stack decisions and verified versions
+- Drizzle ORM transactions: `db.transaction()` -- verified in category.service.ts (deleteCategory uses it)
+
+### Secondary (MEDIUM confidence)
+- TanStack Router `validateSearch` for search param validation -- documented in TanStack Router docs, used for tab routing
+
+### Tertiary (LOW confidence)
+- Image file copy on resolution -- needs implementation validation (best practice, but filesystem operations in Bun may have edge cases)
+
+## Metadata
+
+**Confidence breakdown:**
+- Standard stack: HIGH -- no new libraries, all from Phase 1
+- Architecture: HIGH -- direct extension of proven Phase 1 patterns, schema/service/route/hook layers
+- Pitfalls: HIGH -- drawn from analysis of resolution flow edge cases and Phase 1 experience
+- Database schema: HIGH -- mirrors items table (locked decision), transaction pattern established in category.service.ts

+
+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.

+| Requirement | Source Plan | Description                                                                | Status          | Evidence                                                                |
+|-------------|-------------|----------------------------------------------------------------------------|-----------------|-------------------------------------------------------------------------|
+| THRD-01     | 02-01, 02-02 | User can create a planning thread with a name                              | SATISFIED       | `POST /api/threads` (service + route) + `PlanningView` create form      |
+| THRD-02     | 02-01, 02-02 | User can add candidate products with weight, price, notes, and product link | SATISFIED       | `POST /api/threads/:id/candidates` + `CandidateForm` + `CandidateCard` |
+| THRD-03     | 02-01, 02-02 | User can edit and remove candidates from a thread                          | SATISFIED       | `PUT/DELETE /api/threads/:threadId/candidates/:candidateId` + Edit/Delete on CandidateCard + delete dialog |
+| THRD-04     | 02-01, 02-02 | User can resolve a thread by picking a winner, which moves to collection   | SATISFIED       | `POST /api/threads/:id/resolve` (atomic transaction) + `ResolveDialog` in `__root.tsx` + cross-query invalidation |
+
+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

+    - 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.

+    **1. Create SetupCard.tsx (reference ThreadCard.tsx pattern):**
+    - Props: `id: number`, `name: string`, `itemCount: number`, `totalWeight: number`, `totalCost: number`
+    - 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
+

+
+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

+- 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.

+    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

+- How the checklist picker handles a large number of items (scroll behavior)
+- Error states and loading skeletons

+
+<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

+```
+
+### 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.

+- **Per task commit:** `bun test tests/services/setup.service.test.ts && bun test tests/routes/setups.test.ts`
+- **Per wave merge:** `bun test`
+- **Phase gate:** Full suite green before `/gsd:verify-work`
+
+### Wave 0 Gaps
+- [ ] `tests/services/setup.service.test.ts` -- covers SETP-01, SETP-02, SETP-03
+- [ ] `tests/routes/setups.test.ts` -- covers SETP-01, SETP-02 API layer
+- [ ] `tests/helpers/db.ts` -- needs `setups` and `setup_items` CREATE TABLE statements added

+## Sources
+
+### Primary (HIGH confidence)
+- Existing codebase: `src/db/schema.ts`, `src/server/services/thread.service.ts`, `src/server/routes/threads.ts` -- direct pattern references
+- Existing codebase: `src/client/hooks/useThreads.ts`, `src/client/stores/uiStore.ts` -- client-side patterns
+- Existing codebase: `tests/services/thread.service.test.ts`, `tests/helpers/db.ts` -- test infrastructure patterns

+- TanStack Router file-based routing conventions -- verified against existing `routeTree.gen.ts` auto-generation
+
+### Tertiary (LOW confidence)
+- None
+
+## Metadata
+
+**Confidence breakdown:**
+- Standard stack: HIGH -- no new dependencies, all patterns established in Phases 1-2
+- Architecture: HIGH -- direct 1:1 mapping from thread patterns to setup patterns, only new concept is junction table
+- Pitfalls: HIGH -- identified from direct codebase analysis (hardcoded links, TotalsBar in root, cascade behavior)

+
+### Observable Truths
+
+Combined must-haves from Plan 01 (backend) and Plan 02 (frontend).
+
+| #  | Truth | Status | Evidence |
+|----|-------|--------|----------|
+| 1  | Setup CRUD operations work (create, read, update, delete) | VERIFIED | `setup.service.ts` exports all 5 functions; all 7 API routes implemented in `setups.ts`; 24 tests passing |
+| 2  | Items can be added to and removed from a setup via junction table | VERIFIED | `syncSetupItems` (delete-all + re-insert) and `removeSetupItem` both implemented; cascade FKs on both sides of `setup_items` |
+| 3  | Setup totals (weight, cost, item count) are computed correctly via SQL aggregation | VERIFIED | `getAllSetups` uses COALESCE subqueries; test confirms 2000g/50000c sums and 0-fallback for empty setups |
+| 4  | Deleting a setup cascades to setup_items; deleting a collection item cascades from setup_items | VERIFIED | Both FK sides use `ON DELETE CASCADE`; test in `setup.service.test.ts` confirms item deletion removes it from setups |
+| 5  | User sees dashboard at / with three summary cards (Collection, Planning, Setups) | VERIFIED | `src/client/routes/index.tsx` renders three `DashboardCard` components using `useTotals`, `useThreads`, `useSetups` |
+| 6  | User can navigate to /collection and see the existing gear/planning tabs | VERIFIED | `src/client/routes/collection/index.tsx` registers `createFileRoute("/collection/")` with gear/planning tab logic |
+| 7  | User can create a named setup from the setups list page | VERIFIED | `src/client/routes/setups/index.tsx` has inline form calling `useCreateSetup()`; clears on success |
+| 8  | User can add/remove collection items to a setup via checklist picker | VERIFIED | `ItemPicker.tsx` uses `useSyncSetupItems`; `ItemCard.tsx` has `onRemove` prop calling `useRemoveSetupItem`; both wired in `$setupId.tsx` |
+| 9  | User can see total weight and cost for a setup in the sticky bar | VERIFIED | Setup detail page computes totals client-side from `setup.items` array; renders in sticky bar at `top-14` |
+| 10 | GearBox title in TotalsBar links back to dashboard from all sub-pages | VERIFIED | `TotalsBar` accepts `linkTo` prop; `__root.tsx` passes `linkTo="/"` on all non-dashboard routes; dashboard passes empty stats (title only) |
+
+**Score:** 10/10 truths verified
+
+---
+
+### Required Artifacts
+
+#### Plan 01 Artifacts

+
+### 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)
