dependency_graph:
|
|
requires:
|
|
- 04-01 (lists/list_shares schema, test harness, BrowserRouter shell)
|
|
- 04-02 (listAccess.ts, listEmitter.ts primitives)
|
|
provides:
|
|
- POST/GET/PATCH/DELETE /api/lists with scoped access (D-04) and auto-share (D-01/D-02)
|
|
- listsRouter mounted at /api/lists in index.ts
|
|
- ListsIndex wired to real data (useQuery + useMutation)
|
|
- ListCard with name/count badge/Shared pill + hover-reveal delete
|
|
- CreateListSheet (Shared default D-01, optimistic useMutation)
|
|
- ListDeleteDialog (mirrors Phase 3 pattern, props-driven, D-06)
|
|
- ListsEmptyState (standalone component)
|
|
- listsClient: fetchLists/createList/patchList/deleteList + List/ListItem types
|
|
affects:
|
|
- apps/api/src/routes/lists.ts (new)
|
|
- apps/api/src/index.ts (listsRouter mount added)
|
|
- apps/api/tests/routes/lists.test.ts (it.todo stubs replaced with real assertions)
|
|
- apps/pwa/src/api/listsClient.ts (expanded with create/patch/delete)
|
|
- apps/pwa/src/routes/ListsIndex.tsx (rewritten with real data)
|
|
tech_stack:
|
|
added: []
|
|
patterns:
|
|
- resolveUserId helper copied verbatim from events.ts (per-router duplication convention)
|
|
- getAccessibleListIds via two-select+Set for D-04 scoped GET
|
|
- Auto-share on create: INSERT list_shares for all users WHERE id != creator (OQ-3/D-01/D-02)
|
|
- Plan 06 SSE seam comments at every mutation handler (publishListEvent)
|
|
- useMutation with optimistic update + onError rollback + onSettled invalidate
|
|
- Props-driven ListDeleteDialog (not Zustand-coupled) to avoid modifying stable calendarStore dialog
|
|
key_files:

modified:

- apps/api/src/index.ts (listsRouter import + app.route mount)
|
|
- apps/api/tests/routes/lists.test.ts (it.todo stubs replaced with 23 real integration tests)
|
|
- apps/pwa/src/api/listsClient.ts (createList/patchList/deleteList + List type expanded)
|
|
- apps/pwa/src/routes/ListsIndex.tsx (rewritten — real data, ListCard, CreateListSheet, ListDeleteDialog)
|
|
decisions:
|
|
- "D-04 GET scoped: two-select + Set union (owner + list_shares) matches listAccess.ts pattern"
|
|
- "DELETE owner-only: safe default per plan spec; sharees can edit but not delete in LIST-01"
|
|
- "ListDeleteDialog is props-driven (not Zustand) to keep calendarStore dialog untouched (stable)"
|
|
- "Plan 06 SSE seam comments left at every mutation handler (publishListEvent not yet wired)"
|
|
- "dev-user (id=1) must exist in users table for dev bypass to work with write endpoints (pre-existing env constraint)"
|
|
- "[Rule 1] @hono/zod-validator returns 400 (not 422); tests corrected to match events.ts convention"

# Phase 4 Plan 3: List CRUD Vertical Slice Summary
|
|
|
|
**One-liner:** Full lists CRUD vertical slice (LIST-01) — POST/GET/PATCH/DELETE /api/lists with D-04 scoped access + auto-share-on-create, wired to ListsIndex/ListCard/CreateListSheet/ListDeleteDialog UI with optimistic mutations.
|

## TDD Gate Compliance
|
|
|
|
| Gate | Commit | Status |
|
|
|------|--------|--------|
|
|
| RED — 23 failing integration tests | 2b3d789 | PASS — all 23 failed (404, router not mounted) |
|
|
| GREEN — listsRouter + index mount | 9546b74 | PASS — all 23 tests pass |
|
|
| REFACTOR | (skipped) | Implementation was clean on first pass |

## Deviations from Plan
|
|
|
|
### Auto-fixed Issues
|
|
|
|
**1. [Rule 1 - Bug] @hono/zod-validator returns HTTP 400, not 422**
|
|
- **Found during:** GREEN phase — 4 zod validation tests failed with `expected 422 to be 400`
|
|
- **Issue:** The plan specified 422 for zod validation failures, but `@hono/zod-validator` returns 400 (matching the existing events.ts convention in the codebase).
|
|
- **Fix:** Updated test assertions to expect 400, with an inline comment explaining the choice is consistent with events.ts convention.
|
|
- **Files modified:** `apps/api/tests/routes/lists.test.ts`
|
|
- **Commit:** 9546b74

## Playwright Browser Check
|
|
|
|
Ran against `http://localhost:5173/lists` with API on `http://localhost:3000` (DEV_AUTH_BYPASS=true):
|
|
|
|
1. `/lists` renders empty state: "No lists yet" + "Tap + to create your first shared list…" — PASS
|
|
2. Click "+ New list" FAB → CreateListSheet opens with name input auto-focused, Shared/Private toggle defaulting to Shared, Create button disabled (empty name) — PASS
|
|
3. Type "Groceries" → Create → sheet closes, card appears with "Shared" pill and "0 items" — PASS
|
|
4. Create "Gift Ideas" → second card appears — PASS
|
|
5. Hover "Gift Ideas" card → delete (X) icon appears → click → ListDeleteDialog opens with correct heading + body text — PASS
|
|
6. Click "Delete" → dialog closes, "Gift Ideas" card disappears, only "Groceries" remains — PASS
|
|
|
|
## Verification Results
|
|
|
|
### API Tests
|
|
- `tests/routes/lists.test.ts`: 23 passed (0 failed)
|
|
- D-04 negative test ("does NOT return private list of another user") — GREEN
|
|
- All create/get/delete/patch/scope assertions green
|
|
|
|
### Full API Suite
|
|
- 16 passed | 2 skipped (Wave-0 stubs) | 140 passed | 22 todo — no regressions
|
|
|
|
### TypeScript
|
|
- `pnpm --filter @familysync/api typecheck` — PASS
|
|
- `pnpm --filter @familysync/pwa exec tsc --noEmit` — PASS
|
|
|
|
### Existing Tests
|
|
- `apps/pwa/src/components/DeleteConfirmationDialog.test.tsx` — 10 passed (regression guard green)
|
|
- `DeleteConfirmationDialog.tsx` NOT modified
|
|
|
|
## Known Stubs
|
|
|
|
| File | Stub | Reason |
|
|
|------|------|--------|
|
|
| `apps/pwa/src/routes/ListsIndex.tsx:66` | `// TODO: surface "Couldn't delete. Try again." toast` | Plan 06 adds the notification layer once SSE and toast pattern are established |
|
|
| `apps/api/src/routes/lists.ts` | Plan 06 SSE seam comments (`publishListEvent` calls commented out) | Plan 06 adds fan-out once the SSE `/api/sse/lists` endpoint exists |
|
|
|
|
Neither stub prevents the plan's goal (create + delete named lists). Both are forward-seam comments, not data gaps.
|
|
|
|
## Threat Surface Scan
|
|
|
|
All threats from the plan's threat model are mitigated:
|
|
|
|
| Threat ID | Status | Notes |
|
|
|-----------|--------|-------|
|
|
| T-04-05 (EoP — private list via direct id) | Mitigated | checkListAccess() on every mutation; 403 tested |
|
|
| T-04-02 (Info Disclosure — GET leaking non-shared lists) | Mitigated | Two-select + Set scope; negative test asserts absence |
|
|
| T-04-06 (Tampering — XSS via list name) | Mitigated | All list names plain-text JSX children; no dangerouslySetInnerHTML |
|
|
| T-04-07 (Tampering — overposting on PATCH) | Mitigated | patchListSchema whitelists name/isShared only; 400 tested |
|
|
| T-04-08 (EoP — self-adding to list_shares) | Mitigated | Shares server-managed only; no client-writable shares endpoint |
|
|
|
|
No new threat surface beyond the plan's trust boundaries.
