## Goal Achievement

### Observable Truths

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | Clicking Add on a catalog search card in collection mode opens the AddToCollectionModal | ✓ VERIFIED | `CatalogSearchOverlay.tsx` line 105: `if (catalogSearchMode === "collection") { openAddToCollection(item.id, itemName) }` |
| 2 | AddToCollectionModal shows category dropdown, optional notes, optional purchase price, and submit/cancel buttons | ✓ VERIFIED | `AddToCollectionModal.tsx` — all four form fields present (lines 99–173): category `<select>`, notes `<textarea>`, purchase price `<input type="number">`, submit + cancel buttons |
| 3 | Submitting the modal creates a reference item with globalItemId and personal fields | ✓ VERIFIED | `AddToCollectionModal.tsx` line 56–63: `createItem.mutate({ name, categoryId, globalItemId, notes, purchasePriceCents })`. API route uses `createItemSchema` which accepts `globalItemId`. Service writes all fields to DB |
| 4 | Success toast appears after adding item to collection | ✓ VERIFIED | `AddToCollectionModal.tsx` line 66: `toast.success("Added to Collection")` on mutation `onSuccess`. `Toaster` rendered in `__root.tsx` line 214 |
| 5 | Clicking Add to Collection on the global item detail page opens the same modal | ✓ VERIFIED | `$globalItemId.tsx` line 136: `onClick={() => openAddToCollection(item.id, ...)`. Same UIStore action consumed by `AddToCollectionModal` |
| 6 | Clicking Add on a catalog search card in thread mode opens the AddToThreadModal with a thread picker | ✓ VERIFIED | `CatalogSearchOverlay.tsx` line 108: `if (catalogSearchMode === "thread") { openAddToThread(item.id, itemName) }`. `AddToThreadModal` renders thread `<select>` in "pick" mode |
| 7 | User can select an existing active thread and the catalog item is added as a candidate | ✓ VERIFIED | `AddToThreadModal.tsx` lines 94–121: `handleAddToExistingThread()` calls `apiPost(/api/threads/${selectedThreadId}/candidates, { globalItemId, ... })`. Query cache invalidated afterward |
| 8 | User can choose New Thread which shows thread name + category fields and creates thread + candidate in one step | ✓ VERIFIED | `AddToThreadModal.tsx` lines 123–151: `handleCreateThreadAndAdd()` calls `createThread.mutateAsync()` then `apiPost` to add candidate. "New Thread..." option at line 202 switches `mode` to "create" |
| 9 | After creating a new thread, subsequent adds in same session default to that thread | ✓ VERIFIED | Both submit handlers call `setCatalogSessionThreadId(...)`. Initialization `useEffect` (line 49–66) pre-selects `catalogSessionThreadId` when modal re-opens in the same session |

**Score: 9/9 truths verified**

### Key Link Verification

| From | To | Via | Status | Details |
|------|----|-----|--------|---------|
| `CatalogSearchOverlay.tsx` | `uiStore.ts` | `openAddToCollection` call replacing handleAddStub | ✓ WIRED | `handleAddStub` absent; `openAddToCollection` called at line 106; `openAddToThread` called at line 108 |
| `AddToCollectionModal.tsx` | `/api/items` | `useCreateItem` mutation with `globalItemId` | ✓ WIRED | `useCreateItem()` imported and called; `globalItemId` passed in mutation payload (line 60) |
| `$globalItemId.tsx` | `uiStore.ts` | `openAddToCollection` on button click | ✓ WIRED | `useUIStore` imported; `openAddToCollection` destructured (line 14); called on button `onClick` (line 136) |
| `uiStore.ts` | `AddToThreadModal.tsx` | `addToThreadModal` + `catalogSessionThreadId` consumed | ✓ WIRED | `AddToThreadModal` reads `addToThreadModal`, `catalogSessionThreadId`, `setCatalogSessionThreadId` from `useUIStore` |
| `AddToThreadModal.tsx` | `/api/threads` | `useCreateThread` for new thread creation | ✓ WIRED | `useCreateThread` imported (line 6); `createThread.mutateAsync()` called in `handleCreateThreadAndAdd` (line 129) |
| `AddToThreadModal.tsx` | `/api/threads/:threadId/candidates` | `apiPost` for candidate creation | ✓ WIRED | `apiPost` called at lines 100 and 133 with `globalItemId` in request body |
| `AddToThreadModal.tsx` | `uiStore.ts` | `setCatalogSessionThreadId` to remember thread selection | ✓ WIRED | Called at lines 111 and 141 after successful candidate add |

### Data-Flow Trace (Level 4)

| Artifact | Data Variable | Source | Produces Real Data | Status |
|----------|---------------|--------|--------------------|--------|
| `AddToCollectionModal.tsx` | `categories` | `useCategories()` → `GET /api/categories` → Drizzle query | Yes — DB query returns category rows | ✓ FLOWING |
| `AddToCollectionModal.tsx` | `createItem` mutation result | `useCreateItem()` → `apiPost /api/items` → item service → Drizzle insert | Yes — DB insert with `globalItemId` field | ✓ FLOWING |
| `AddToThreadModal.tsx` | `threads` (active threads) | `useThreads()` → `GET /api/threads` → Drizzle query | Yes — filtered to `status === "active"` client-side | ✓ FLOWING |
| `AddToThreadModal.tsx` | `globalItem` | `useGlobalItem(globalItemId)` → `GET /api/global-items/:id` → Drizzle query | Yes — `weightGrams`/`priceCents` passed to candidate payload | ✓ FLOWING |
| `AddToThreadModal.tsx` | candidate creation result | `apiPost /api/threads/:id/candidates` → thread service → Drizzle insert | Yes — `globalItemId` stored on candidate row (confirmed by test at line 657) | ✓ FLOWING |

### Behavioral Spot-Checks

Step 7b: SKIPPED — all entry points are React components requiring a running browser. No runnable CLI or server-only logic was introduced by this phase. The build is the appropriate automated check.

Build verification (from SUMMARY.md — both plans report `bun run build` exits 0, code 0 on type checks):

| Behavior | Check | Status |
|----------|-------|--------|
| No TypeScript errors in new files | `bun run build` (plan 01 + 02 acceptance) | ✓ PASS (per summaries) |
| CATFLOW-06 regression — resolveThread with globalItemId | `tests/services/thread.service.test.ts` lines 704–725 | ✓ COVERED — test exists and verifies `result.item?.globalItemId === gi.id` |
| Commits exist for documented hashes | `git log f309c73 ed76236 c33b7c7` | ✓ VERIFIED — all three hashes resolve |

### Requirements Coverage

| Requirement | Source Plan | Description | Status | Evidence |
|-------------|-------------|-------------|--------|----------|
| CATFLOW-03 | 22-01-PLAN.md | User can add a catalog item to collection as a reference item with personal fields (category, notes, purchase price, image, quantity) | ✓ SATISFIED | `AddToCollectionModal` provides category, notes, purchase price. Image inherited via service-layer `globalItemId` join (item.service.ts lines 34, 74). Quantity defaults to 1 at DB level. Image upload and quantity fields explicitly excluded from modal scope per DISCUSSION-LOG decision D-02 (compact modal = minimal friction). REQUIREMENTS.md marks CATFLOW-03 complete across Phases 19 and 22. |
| CATFLOW-05 | 22-02-PLAN.md | Thread candidates can be added from catalog with global item link | ✓ SATISFIED | `AddToThreadModal` creates candidates via `apiPost /api/threads/:id/candidates` with `globalItemId` in payload. Thread service stores `globalItemId` on candidate row. |
| CATFLOW-06 | 22-02-PLAN.md | Thread resolution with catalog-linked candidate creates reference item with auto-link | ✓ SATISFIED | Existing `thread.service.test.ts` line 704 test: "resolveThread with candidate having globalItemId creates a reference item". No Phase 22 code change was required — existing `resolveThread` service already handles this correctly, confirmed by test coverage. |

No orphaned requirements: all three IDs declared in plan frontmatter map to confirmed implementations. REQUIREMENTS.md shows CATFLOW-03, CATFLOW-05, CATFLOW-06 all marked `[x]` complete with Phase 22 listed.

### Anti-Patterns Found

| File | Pattern | Severity | Impact |
|------|---------|----------|--------|
| `CatalogSearchOverlay.tsx` line 409/420 | `onAdd={() => handleAdd(item)}` — `onAdd` prop no longer receives `MouseEvent` (CardProps type changed from `(e: React.MouseEvent) => void` to `() => void`) | ℹ️ Info | `e.stopPropagation()` from the original plan stub was dropped — the Add button is inside a card that has no `onClick` navigation handler, so event bubbling is benign. Not a functional issue. |

No TODO/FIXME/placeholder code, no empty return stubs, no hardcoded empty data arrays flowing to user-visible output.

### Human Verification Required

The following flows require a running browser with an authenticated session. Automated code inspection confirms the wiring is complete; the tests below verify user-observable behavior.

#### 1. Add to Collection — catalog search entry point

**Test:** Open the app, click the FAB, select "Add to Collection". In the catalog overlay, search for any item and click "Add".
**Expected:** AddToCollectionModal opens showing the item name, a category dropdown pre-selected to the first category, a notes textarea, and a purchase price input. Fill in a category, click "Add to Collection". A toast "Added to Collection" appears. Navigate to /collection — the item is present.
**Why human:** Modal render and toast display require a live browser. Toast timing and overlay persistence after submit cannot be verified statically.

#### 2. Add to Collection — global item detail page entry point

**Test:** Navigate to `/global-items/:id` for any item. Verify both "Add to Collection" (filled/primary) and "Add to Thread" (outlined/secondary) buttons are visible. Click "Add to Collection".
**Expected:** Same AddToCollectionModal opens with the correct item name. Submit works and toast appears.
**Why human:** Button visibility and correct styling require browser rendering.

#### 3. Add to Thread — existing thread selection + session memory

**Test:** Ensure at least one active thread exists. Click FAB > "Start Thread". In the overlay, click "Add" on any item.
**Expected:** AddToThreadModal opens in "pick" mode showing active threads in a dropdown with category names alongside thread names. Select a thread and click "Add as Candidate". Toast "Added to [Thread Name]" appears. Click "Add" on another item — the previously selected thread is pre-selected.
**Why human:** Session thread memory requires observing state across multiple modal open/close cycles. Thread dropdown population requires real thread data.

#### 4. New Thread creation from thread picker

**Test:** In thread mode, click "Add" on a catalog item. In the thread picker dropdown, select "+ New Thread...".
**Expected:** Form switches to "New Thread + Candidate" mode with thread name input and category dropdown. A "Back to thread picker" link is visible if active threads exist. Fill in a thread name, select a category, click "Create & Add". Toast "Created [name] with first candidate" appears. Click "Add" on another item — the new thread is pre-selected.
**Why human:** Mode switching animation, back-navigation between pick/create modes, and toast content require browser observation.

#### 5. Thread resolution regression (CATFLOW-06)

**Test:** Resolve a thread whose winning candidate has a `globalItemId` (i.e., was added from the catalog in Flow 3 or 4). Click "Pick Winner" on that candidate.
**Expected:** The resolved item appears in the collection with its `globalItemId` set, inheriting global item data (weight, price, image from catalog).
**Why human:** Full resolution → collection navigation requires a live app and real DB state. The unit test at line 704 covers the service logic; this test verifies the UI path.

### Gaps Summary

No automated gaps found. All 9 observable truths are VERIFIED in code. All 3 requirement IDs are satisfied. All key links are wired. All artifacts pass Levels 1–4 (exist, substantive, wired, data flowing).

Five items are routed to human verification because they involve browser rendering, toast display, modal state transitions, and real session/DB state that cannot be confirmed by static code inspection alone.
