<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.

<!-- Existing code the executor needs to understand -->
From src/db/schema.ts (existing tables to extend):
```typescript

id: integer("id").primaryKey({ autoIncrement: true }),
name: text("name").notNull().unique(),
emoji: text("emoji").notNull().default("\u{1F4E6}"),

```
From src/shared/schemas.ts (existing pattern to follow):
```typescript
export const createItemSchema = z.object({
name: z.string().min(1, "Name is required"),
weightGrams: z.number().nonnegative().optional(),
priceCents: z.number().int().nonnegative().optional(),
categoryId: z.number().int().positive(),

```
From src/server/index.ts (route mounting):
```typescript
app.route("/api/items", itemRoutes);

- createThread: creates thread with name, returns thread with id/status/timestamps
- getAllThreads: returns active threads with candidateCount, minPriceCents, maxPriceCents; excludes resolved by default; includes resolved when includeResolved=true
- getThreadWithCandidates: returns thread with nested candidates array including category info; returns null for non-existent thread
- createCandidate: adds candidate to thread with all item-compatible fields (name, weightGrams, priceCents, categoryId, notes, productUrl, imageFilename)
- updateCandidate: updates candidate fields, returns updated candidate; returns null for non-existent
- deleteCandidate: removes candidate, returns deleted candidate; returns null for non-existent
- updateThread: updates thread name
- deleteThread: removes thread and cascading candidates
- resolveThread: atomically creates collection item from candidate data and sets thread status to "resolved" with resolvedCandidateId; fails if thread not active; fails if candidate not in thread; fails if candidate not found
</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.
All tests must pass after implementation.

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

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

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

<!-- Existing components to reuse/reference -->
From src/client/stores/uiStore.ts (extend this):
```typescript
interface UIState {
panelMode: "closed" | "add" | "edit";
editingItemId: number | null;
confirmDeleteItemId: number | null;
openAddPanel: () => void;
openEditPanel: (itemId: number) => void;
closePanel: () => void;
openConfirmDelete: (itemId: number) => void;
closeConfirmDelete: () => void;
}
```
From src/client/routes/__root.tsx (modify for tab-aware layout):
```typescript
// Currently renders TotalsBar, Outlet, SlideOutPanel (item-specific), ConfirmDialog, FAB
// Need to: make SlideOutPanel and FAB context-aware (items vs candidates)
// Need to: add candidate panel handling alongside item panel
```
From src/client/routes/index.tsx (refactor to add tabs):
```typescript
// Currently: CollectionPage renders items grouped by category
// Becomes: HomePage with tab switcher, CollectionView (existing content) and PlanningView (new)
```
From src/client/hooks/useItems.ts (pattern to follow for hooks):
```typescript
// Uses apiGet, apiPost, apiPut, apiDelete from "../lib/api"
// Uses useQuery with queryKey: ["items"]
// Uses useMutation with onSuccess: invalidateQueries(["items"])
```
API endpoints from Plan 01:
- GET /api/threads (optional ?includeResolved=true)
- POST /api/threads { name }
- GET /api/threads/:id (returns thread with candidates)
- PUT /api/threads/:id { name }
- DELETE /api/threads/:id
- POST /api/threads/:id/candidates (form data with optional image)
- PUT /api/threads/:threadId/candidates/:candidateId
- DELETE /api/threads/:threadId/candidates/:candidateId
- POST /api/threads/:id/resolve { candidateId }

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

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

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

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

# 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)
</user_constraints>
<phase_requirements>
## Phase Requirements
| ID | Description | Research Support |
|----|-------------|-----------------|
| THRD-01 | User can create a planning thread with a name | New `threads` table, thread service `createThread()`, POST /api/threads endpoint, thread creation UI (inline input or slide-out) |
| THRD-02 | User can add candidate products to a thread with weight, price, notes, and product link | New `thread_candidates` table with same fields as items + threadId FK, candidate service, POST /api/threads/:id/candidates, reuse ItemForm with minor adaptations |
| THRD-03 | User can edit and remove candidates from a thread | PUT/DELETE /api/threads/:threadId/candidates/:id, reuse SlideOutPanel + adapted ItemForm for edit, ConfirmDialog pattern for delete |
| THRD-04 | User can resolve a thread by picking a winner, which moves to their collection | `resolveThread()` service function: transactionally create item from candidate data + set thread status to "resolved", ConfirmDialog for confirmation, cache invalidation for both threads and items queries |
</phase_requirements>
## Standard Stack
### Core (Already Installed from Phase 1)
| Library | Version | Purpose | Phase 2 Usage |
|---------|---------|---------|---------------|
| Hono | 4.12.x | Backend API | New thread + candidate route handlers |
| Drizzle ORM | 0.45.x | Database ORM | New table definitions, migration, transactional resolution |
| TanStack Router | 1.x | Client routing | Tab navigation, thread detail route |
| TanStack Query | 5.x | Server state | useThreads, useCandidates hooks |
| Zustand | 5.x | UI state | Thread panel state, confirm dialog state |
| Zod | 4.x | Validation | Thread and candidate schemas |
| @hono/zod-validator | 0.7.6+ | Route validation | Validate thread/candidate request bodies |
### No New Dependencies Required
Phase 2 uses the exact same stack as Phase 1. No new libraries needed.
## Architecture Patterns
### New Files Structure
```
src/
db/
schema.ts # ADD: threads + thread_candidates tables
shared/
schemas.ts # ADD: thread + candidate Zod schemas
types.ts # ADD: Thread, Candidate types
server/
index.ts # ADD: mount thread routes
routes/
threads.ts # NEW: /api/threads CRUD + resolution
services/
thread.service.ts # NEW: thread + candidate business logic
client/
routes/
index.tsx # MODIFY: add tab navigation, move collection into tab
threads/
index.tsx # NEW: thread detail view (or use search params)
components/
ThreadCard.tsx # NEW: thread card for thread list
CandidateCard.tsx # NEW: candidate card (adapts ItemCard pattern)
CandidateForm.tsx # NEW: candidate add/edit form (adapts ItemForm)
ThreadTabs.tsx # NEW: tab switcher component
hooks/
useThreads.ts # NEW: thread CRUD hooks
useCandidates.ts # NEW: candidate CRUD + resolution hooks
stores/
uiStore.ts # MODIFY: add thread-specific panel/dialog state
tests/
helpers/
db.ts # MODIFY: add threads + candidates table creation
services/
thread.service.test.ts # NEW: thread + candidate service tests
routes/
threads.test.ts # NEW: thread API integration tests
```
### 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 }),

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

## 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: `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

| 8 | User can switch between My Gear and Planning tabs on the home page | VERIFIED | `index.tsx:13-15,32-34``z.enum(["gear","planning"])` search schema; `ThreadTabs` renders tabs; conditionally renders `CollectionView` or `PlanningView` |
| 9 | User can see a list of planning threads as cards with name, candidate count, date, and price range | VERIFIED | `ThreadCard.tsx:63-74` — renders candidateCount chip, date chip, priceRange chip; `index.tsx:236-248` maps threads to ThreadCards |
| 10 | User can create a new thread from the Planning tab | VERIFIED | `index.tsx:172-210` — form with `onSubmit` calls `createThread.mutate({ name })`; not a stub (contains input, validation, pending state) |
| 11 | User can click a thread card to see its candidates as a card grid | VERIFIED | `ThreadCard.tsx:44-47``onClick` navigates to `/threads/$threadId`; `$threadId.tsx:128-144` — grid of `CandidateCard` components |

### Key Link Verification
| From | To | Via | Status | Details |
|---------------------------------------------|-------------------------------------------------|-----------------------------------------|----------|---------------------------------------------------------------------------|
| `src/server/routes/threads.ts` | `src/server/services/thread.service.ts` | service function calls | WIRED | Line 1-20: imports all service functions; all routes invoke them |
| `src/server/services/thread.service.ts` | `src/db/schema.ts` | Drizzle queries on threads/threadCandidates | WIRED | Line 2: `import { threads, threadCandidates, items, categories } from "../../db/schema.ts"` |
| `src/server/services/thread.service.ts` | `src/server/services/item.service.ts` | resolveThread uses items table | WIRED | `resolveThread` inserts directly into `items` table via Drizzle (imported from schema, not item.service — same net effect) |
| `src/server/index.ts` | `src/server/routes/threads.ts` | app.route mount | WIRED | `index.ts:9,27` — imported and mounted at `/api/threads` |
| `src/client/hooks/useThreads.ts` | `/api/threads` | apiGet/apiPost/apiDelete | WIRED | Lines 47, 64, 76, 87, 104 — all hooks call correct API paths |
| `src/client/hooks/useCandidates.ts` | `/api/threads/:id/candidates` | apiPost/apiPut/apiDelete | WIRED | Lines 23, 39, 54 — candidate endpoints called with correct patterns |
| `src/client/hooks/useThreads.ts` | `queryClient.invalidateQueries` | cross-invalidation on resolution | WIRED | `useResolveThread` invalidates `threads`, `items`, and `totals` on success (lines 108-110) |
| `src/client/routes/index.tsx` | `src/client/components/ThreadCard.tsx` | renders thread cards in Planning tab | WIRED | `index.tsx:10,237` — imported and used in `PlanningView` |
| `src/client/routes/threads/$threadId.tsx` | `src/client/components/CandidateCard.tsx` | renders candidate cards in thread detail | WIRED | `$threadId.tsx:3,130` — imported and used in candidate grid |
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.
### Requirements Coverage
| 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.
