## Goal Achievement

### Observable Truths

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | Navigating to /items/:id renders a full detail page with all item data | ✓ VERIFIED | `src/client/routes/items/$itemId.tsx` (454 lines), createFileRoute("/items/$itemId"), renders name, weight/price badges, notes, quantity, product link, image |
| 2 | Item detail page shows hero image, name, weight/price/category badges, notes, quantity, purchase price, product link | ✓ VERIFIED | File substantive at 454 lines; isLoading/isError states handled; ImageUpload and CategoryPicker wired in edit mode |
| 3 | Clicking Edit toggles fields to editable inputs; Save persists via updateItem mutation | ✓ VERIFIED | `isEditing` state + `useUpdateItem()` with `onSuccess: () => setIsEditing(false)` confirmed in file |
| 4 | Navigating to /global-items/:id shows enhanced catalog page with Add to Collection button | ✓ VERIFIED | `src/client/routes/global-items/$globalItemId.tsx` has button at line 131; stub documented per plan (Phase 22 wires it) |
| 5 | Catalog detail page shows hero image, brand, model, specs, description, owner count | ✓ VERIFIED | useGlobalItem hook connected; 148-line file with all sections present |
| 6 | Navigating to /threads/:threadId/candidates/:candidateId renders a full candidate detail page | ✓ VERIFIED | `src/client/routes/threads/$threadId/candidates/$candidateId.tsx` (506 lines), createFileRoute with correct path |
| 7 | Candidate detail page shows name, weight, price, notes, pros, cons, status, product link, image | ✓ VERIFIED | useThread + candidates.find pattern; isEditing toggle; all fields confirmed in 506-line file |
| 8 | Thread detail page at /threads/:threadId still works after route restructuring | ✓ VERIFIED | `src/client/routes/threads/$threadId/index.tsx` exists (629 lines); flat `$threadId.tsx` deleted; routeTree.gen.ts has no entry for old flat path |
| 9 | Add candidate button on thread page uses modal dialog instead of slide-out panel | ✓ VERIFIED | `addCandidateOpen` state + `AddCandidateModal` component + `useCreateCandidate` wired; no `openCandidateAddPanel` reference remains |
| 10 | Clicking an ItemCard navigates to /items/:id | ✓ VERIFIED | `useNavigate` + `navigate({ to: "/items/$itemId", params: ... })` in ItemCard.tsx; `openEditPanel` fully removed |
| 11 | Clicking a CandidateCard navigates to /threads/:threadId/candidates/:candidateId | ✓ VERIFIED | `useNavigate` + correct params in CandidateCard.tsx; `openCandidateEditPanel` removed |
| 12 | Lint passes cleanly | ✗ FAILED | `bun run lint` exits with 20 errors. Phase-21 files contribute: format error in `threads/$threadId/index.tsx` (missing semicolons), unused `imageFilename` param in `ItemCard.tsx` and `CandidateCard.tsx` |
| 13 | REQUIREMENTS.md merge conflict resolved — all DETAIL requirements reflect correct status | ✗ FAILED | Unresolved `<<<<<<< HEAD` / `>>>>>>>` conflict markers at lines 67-71 and 192-196; DETAIL-01, -02, -03, -05 checkboxes in conflict |

**Score:** 11/13 truths verified

### Key Link Verification

| From | To | Via | Status | Details |
|------|----|-----|--------|---------|
| `items/$itemId.tsx` | useItem hook | `useItem(Number(itemId))` | ✓ WIRED | Line 32: type assertion used to access imageUrl enrichment |
| `items/$itemId.tsx` | useUpdateItem mutation | `updateItem.mutate(...)` | ✓ WIRED | Line 40 import + mutation called in save handler |
| `global-items/$globalItemId.tsx` | Add to Collection button | button element + onClick | ✓ WIRED (stub) | console.log stub per plan — Phase 22 wires actual flow |
| `candidates/$candidateId.tsx` | useThread hook | `useThread(threadId)` + `candidates.find` | ✓ WIRED | Lines 35, 57; finds candidate from thread array |
| `candidates/$candidateId.tsx` | useUpdateCandidate mutation | `updateCandidate.mutate(...)` | ✓ WIRED | Line 36 init + called in save handler |
| `ItemCard.tsx` | /items/$itemId route | `useNavigate → /items/$itemId` | ✓ WIRED | Lines 40, 48 — navigate with itemId params |
| `CandidateCard.tsx` | /threads/$threadId/candidates/$candidateId route | `useNavigate → /threads/$threadId/candidates/$candidateId` | ✓ WIRED | Lines 50, 62 — navigate with both params |
| `CatalogSearchOverlay.tsx` | /global-items/$globalItemId route | `useNavigate → /global-items/$globalItemId` | ✓ WIRED | Lines 101, 106 — closeCatalogSearch then navigate |

---

### Data-Flow Trace (Level 4)

| Artifact | Data Variable | Source | Produces Real Data | Status |
|----------|---------------|--------|--------------------|--------|
| `items/$itemId.tsx` | `item` (ItemWithCategory) | `useItem(Number(itemId))` → `apiGet("/api/items/:id")` → Drizzle query | Yes — existing API endpoint with DB query | ✓ FLOWING |
| `global-items/$globalItemId.tsx` | `item` (GlobalItemWithDetails) | `useGlobalItem(Number(globalItemId))` → `apiGet("/api/global-items/:id")` | Yes — existing API endpoint | ✓ FLOWING |
| `candidates/$candidateId.tsx` | `candidate` (from thread.candidates array) | `useThread(threadId)` → `apiGet("/api/threads/:id")` → includes candidates | Yes — thread API returns candidates array | ✓ FLOWING |
| `threads/$threadId/index.tsx` | `thread` (ThreadWithCandidates) | `useThread(threadId)` → same API | Yes — pre-existing data flow preserved | ✓ FLOWING |

---

### Behavioral Spot-Checks

| Behavior | Check | Result | Status |
|----------|-------|--------|--------|
| Route tree includes all 3 new routes | grep routeTree.gen.ts for /items/$itemId, /global-items/$globalItemId, /threads/.../candidates/$candidateId | All 3 found at lines 60, 65, 76 | ✓ PASS |
| No dead panel references in src/client/ | grep for openEditPanel, openCandidateEditPanel, panelMode, candidatePanelMode | 0 results | ✓ PASS |
| openCandidateAddPanel removed from thread index | grep threads/$threadId/index.tsx | 0 matches | ✓ PASS |
| Old flat $threadId.tsx deleted | ls src/client/routes/threads/$threadId.tsx | FLAT_FILE_REMOVED | ✓ PASS |
| UIStore preserves required dialog state | grep openConfirmDelete, openResolveDialog in uiStore.ts | Both present with implementations | ✓ PASS |
| Lint clean | bun run lint | 20 errors, 19 warnings | ✗ FAIL |

---

### Requirements Coverage

| Requirement | Source Plan | Description | Status | Evidence |
|-------------|------------|-------------|--------|----------|
| DETAIL-01 | 21-01 | Clicking a collection item navigates to full detail page (`/items/:id`) showing all item data | ✓ SATISFIED | Route exists (454 lines), ItemCard navigates to it, route registered in routeTree.gen.ts |
| DETAIL-02 | 21-01 | Clicking a catalog search result navigates to public detail page (`/global-items/:id`) with "Add to Collection" button | ✓ SATISFIED | CatalogSearchOverlay.tsx navigates to /global-items/$globalItemId; button present in route file (stub per plan) |
| DETAIL-03 | 21-01 | Item detail page has edit mode toggle for modifying personal fields | ✓ SATISFIED | isEditing state, all personal fields (notes, category, quantity, purchase price) have editable inputs in edit mode |
| DETAIL-04 | 21-02, 21-03 | Thread candidates navigate to detail pages instead of opening slide-out panels | ✓ SATISFIED | CandidateCard and CandidateListItem navigate to /threads/$threadId/candidates/$candidateId; candidate detail page exists |
| DETAIL-05 | 21-03 | Slide-out panels for items and candidates are removed from the application | ✓ SATISFIED | No SlideOutPanel usage in __root.tsx; panel state removed from UIStore; component files preserved on disk per plan |

**Note:** REQUIREMENTS.md has an unresolved merge conflict covering these requirements. The implementation satisfies all five, but the tracking file needs conflict resolution to reflect the correct [x] Complete state for DETAIL-01 through DETAIL-05.

**Orphaned requirements:** None. All 5 requirement IDs from phase plans (DETAIL-01 through DETAIL-05) are accounted for.

---

### Anti-Patterns Found

| File | Line | Pattern | Severity | Impact |
|------|------|---------|----------|--------|
| `src/client/routes/global-items/$globalItemId.tsx` | 133 | `console.log("Add to collection — wired in Phase 22")` | ℹ️ Info | Documented intentional stub; Phase 22 wires actual flow |
| `src/client/routes/threads/$threadId/index.tsx` | 39, 65 | Missing semicolons (format error) | ⚠️ Warning | Causes lint failure; cosmetic only, no runtime impact |
| `src/client/components/ItemCard.tsx` | 32 | `imageFilename` destructured but unused in render (imageUrl used instead) | ⚠️ Warning | Lint error; pre-existing pattern from Phase 17 image refactor; no runtime impact |
| `src/client/components/CandidateCard.tsx` | 37 | Same `imageFilename` unused parameter | ⚠️ Warning | Same root cause as ItemCard |

No blocker anti-patterns found. The "Add to Collection" console.log stub is explicitly planned for Phase 22 and does not block the phase goal.

### Human Verification Required

#### 1. Item Detail Edit Mode Persistence

**Test:** Navigate to `/items/:id` for an existing item. Click "Edit", change the item name or notes, click "Save".
**Expected:** Page returns to read-only view showing the updated values. Refreshing the page shows the saved data.
**Why human:** Mutation side-effects (React Query cache invalidation + server write) cannot be verified by static code inspection.

#### 2. Candidate "Pick as winner" Dialog

**Test:** Navigate to `/threads/:threadId/candidates/:candidateId` for a candidate in an active thread. Click "Pick as winner".
**Expected:** ResolveDialog opens with correct thread and candidate pre-selected.
**Why human:** Dialog render triggered by UIStore state change requires live browser.

#### 3. Catalog Search Card Click Navigation

**Test:** Open catalog search overlay, click on a search result card body (not the "Add" button).
**Expected:** Overlay closes and browser navigates to `/global-items/:id` for that item.
**Why human:** Two-step interaction (closeCatalogSearch + navigate) requires live browser to verify sequencing.

#### 4. Add Candidate Modal on Thread Page

**Test:** Navigate to `/threads/:threadId`, click "Add Candidate".
**Expected:** Modal dialog opens with all form fields (name, weight, price, category, notes, URL, image, pros, cons). Submitting creates a new candidate visible on the thread page.
**Why human:** Modal render and form submission require live browser.

---

### Gaps Summary

Two gaps block a clean pass:

**Gap 1 — Lint failures in phase-21 files.** `bun run lint` reports 20 errors total. The phase-21 files contribute:
- `src/client/routes/threads/$threadId/index.tsx`: Biome format error (missing semicolons at two expression statement positions). Quick fix: `bunx @biomejs/biome format --write src/client/routes/threads/\$threadId/index.tsx`.
- `src/client/components/ItemCard.tsx` and `CandidateCard.tsx`: `imageFilename` is in the destructuring props but not used in the render (they use `imageUrl` from the same API enrichment). This was exposed by the Phase 17 image refactor and carried forward. Fix: remove `imageFilename` from the destructured parameter list, or rename to `_imageFilename` if it needs to remain in the interface for API compatibility.

**Gap 2 — REQUIREMENTS.md merge conflict.** The file has `<<<<<<< HEAD` / `>>>>>>>` markers at lines 67-71 and 192-196 around the DETAIL requirements section. This prevents the requirements table from accurately showing phase completion status. The conflict should be resolved by accepting the worktree-agent-a00c5cfa side which marks DETAIL-05 as [x] Complete, and additionally marking DETAIL-01, DETAIL-02, DETAIL-03 as [x] Complete (the implementation satisfies all of them per this verification).

Both gaps are low-effort fixes and do not represent missing functionality. The core goal — full detail pages replacing slide-out panels — is fully achieved.
