Lucas Berger 59e49ec3da chore(16-03): triage eslint-plugin-security findings to green
- Disable detect-object-injection globally in eslint.config.js: all hits were
  numeric loop array indices (ranks[i]) — not user-controlled keys; zod guards
  real API input boundaries; justification comment added (T-16-09)
- Add inline eslint-disable for detect-non-literal-fs-filename at 2 sites:
  - apps/api/src/index.ts: realpathSync(process.argv[1]) — runtime entry path, not user input
  - apps/api/tests/broker/expand.test.ts: readFileSync of test fixture path — test-controlled
- pnpm lint exits 0 across both apps with --max-warnings 0
- 14 of 15 security rules remain active at error; no blanket file disables

Lucas Berger c2ffd1c1b2 feat(16-01): add boot-time refuse-to-boot guard for dev-bypass in production
- Create apps/api/src/lib/bootGuards.ts with assertNotDevBypassInProduction()
- Guard exits non-zero when NODE_ENV=production AND DEV_AUTH_BYPASS=true (D-08)
- Wire import + call as first statement in isMainModule() block in index.ts
- 3/3 unit tests pass, typecheck green

Lucas Berger b8bb6e7671 fix(09): IN-01 add ordering comments cementing signalOutboxDrain() stays after the enqueue commit 2026-06-12 20:50:26 -04:00
Lucas Berger 8307a7b713 fix(09): WR-01 defer outbox drain emit to a microtask so a throwing listener cannot corrupt the enqueue route response 2026-06-12 20:50:21 -04:00
Lucas Berger 0ebdf4864d feat(09-02): wire initOutboxTrigger() at startup under isMainModule() in index.ts
- extend outboxWorker import to include initOutboxTrigger alongside startOutboxWorker
- call initOutboxTrigger() immediately after startOutboxWorker() inside isMainModule() guard
- gated by isMainModule() so tests importing app never register the drain listener (Pitfall 4)
2026-06-12 16:57:52 -04:00
Lucas Berger 30eff3dcdb feat(09-02): add signalOutboxDrain() after each of four enqueue sites in events.ts
- import signalOutboxDrain from '../lib/outboxTrigger.js'
- Site 1 (POST /create): fire-and-forget signal after outbox insert, before 202
- Site 2 (PATCH edit-as-move): signal after await db.transaction() resolves, not inside callback (D-03)
- Site 3 (PATCH same-calendar update): signal after outbox insert, before 202
- Site 4 (DELETE): signal after outbox insert, before 202
2026-06-12 16:57:21 -04:00
Lucas Berger 2b113045f7 feat(09-01): add scheduleOutboxDrain, drainRequested, initOutboxTrigger; route setInterval through wrapper
- Add import { onOutboxDrain } from outboxTrigger.js
- Add let drainRequested = false (D-05 trailing-re-drain flag)
- Export scheduleOutboxDrain(): void — isDraining guard + drainRequested loop (D-05/T-09-01)
  drainRequested=false reset precedes recursive call (Pitfall 3)
  errors caught via .catch to prevent crash (D-02/T-09-03)
- Export initOutboxTrigger(): void — registers onOutboxDrain(() => scheduleOutboxDrain())
- startOutboxWorker setInterval body: scheduleOutboxDrain() replaces runOutboxDrain().catch()
  15 * 1000 interval unchanged (D-08)
- runOutboxDrain body/isDraining guard/finally unchanged (D-02/D-07)
- Fix trigger-wiring tests: add beforeAll(initOutboxTrigger) to wire EventEmitter listener;
  fix Test C mock to return empty rows on trailing drain (correct D-07 behaviour)
- 30/30 outboxWorker tests GREEN; tsc --noEmit clean
2026-06-12 16:52:36 -04:00
Lucas Berger 1e12d702a1 feat(09-01): create outboxTrigger.ts zero-dependency EventEmitter signal module
- Module-level singleton EventEmitter, single subscriber, no setMaxListeners
- Export signalOutboxDrain(): void — fire-and-forget drain signal (D-04)
- Export onOutboxDrain(handler): () => void — register/unsubscribe listener
- Only imports node:events; zero internal dependencies (no circular import risk)

Lucas Berger 03e953158a fix(13-02): eliminate all ESLint violations — pnpm lint exits 0
- eslint.config.js: disable React Compiler rules (v7 flat.recommended enables
  them; codebase does not use the Compiler); add e2e/ to disableTypeChecked
  block; promote exhaustive-deps to error
- API broker: remove redundant as-casts (outboxWorker, poller, reminderScheduler,
  expand, sync, vevent, spike); add targeted ical.js no-unsafe-assignment/argument
  disables with justifying comments inside try blocks
- API routes/sse.ts: fix no-misused-promises on async writeSSE callback with
  void+IIFE+catch pattern
- API routes/lists.ts: let → const for updateValues
- API tests: remove unused imports (beforeEach, eq, vi); rename unused vars
  with _ prefix; remove unused lastActiveId assignment
- PWA components: void navigate() and void queryClient.invalidateQueries() on
  all fire-and-forget call sites; fix CalendarShell explicit-type-casts;
  Couldn't → HTML entity
- PWA test files: as unknown as Response for partial mock objects; string | null
  type annotation on mockLastSyncedUid; remove async from test callbacks without
  await; act(() => {}) not await act(async () => {}) for sync ops
- sw.ts: restructure Notification.data?.url access as let+if so disable
  comments land on the exact violation lines; void self.skipWaiting()

Lucas Berger bf091102f2 fix(08-fix): IN-01 document MariaDB-only long-unique HASH index dependency 2026-06-11 19:27:11 -04:00
Lucas Berger c0f892cae5 fix(db): squash migrations to single baseline (cold-migrate was broken)
0000_easy_slipstream already created lists/list_shares/list_items and the
calendars unique constraint, but 0001_lists_schema re-created those tables and
0001_calendars_user_url_unique was an orphan (not in _journal) — so a cold
`drizzle-kit migrate` against an empty DB failed with ERROR 1050 'Table lists
already exists'. Dev only survived because its DB was built incrementally; CI
is the first cold migrate and exposed it.

Regenerated a single 0000_baseline.sql from schema.ts. Verified on a fresh
mariadb:11: migrate succeeds, schema is structurally identical to the running
dev DB, `drizzle-kit generate` reports no drift, and all 238 API tests pass.
Local dev DBs must be rebuilt (drop + db:migrate); no prod exists.

Lucas Berger 8343faddce feat(260610-k1z-01): wire persistSessionCookie into index.ts + add unit tests
- Mount persistSessionCookie() immediately after oidcAuthMiddleware() inside !devBypassActive block
- Test A: truthy oidcAuthJwt produces Set-Cookie with Max-Age, SameSite=Lax, HttpOnly, Secure
- Test B: falsy/absent oidcAuthJwt emits no oidc-auth cookie (no-resurrection guard)
2026-06-10 14:32:42 -04:00
Lucas Berger aabcb5d043 feat(260610-k1z-01): add persistSessionCookie() middleware (AUTH-02)
- Re-issues oidc-auth cookie with maxAge so PWA sessions survive close/reopen
- Guards on c.get('oidcAuthJwt'): only runs when @hono/oidc-auth set a valid session
- Falsy oidcAuthJwt falls straight through — no resurrection of deleted/absent cookies
- Cookie attrs mirror the library: httpOnly, secure, sameSite=Lax, conditional domain
- maxAge reads OIDC_AUTH_EXPIRES (default 86400s)

Lucas Berger d9efbc1060 fix(quick-260610-i4x-01): replace node-cron schedule() with setInterval in three broker workers
- poller.ts: setInterval(cb, 5 * 60 * 1000) replaces schedule('*/5 * * * *', cb)
- outboxWorker.ts: setInterval(cb, 15 * 1000) replaces schedule('*/15 * * * * *', cb)
- reminderScheduler.ts: setInterval(cb, 60 * 1000) replaces schedule('* * * * *', cb)
- Remove 'import { schedule } from node-cron' from all three files
- Update doc comments to reflect setInterval and document why (node-cron 4.2.1 silent skip)
- Callback bodies and .catch wrappers unchanged; typecheck clean; 91/91 broker tests pass
2026-06-10 13:06:56 -04:00
Lucas Berger 3fdb242f7e fix(260610-hbu-01): catch-up window + per-uid dedup in reminderScheduler
- Replace [now+14min, now+16min] window with (now, now+16min] catch-up
- Replace minuteBucket-keyed Set with uid-keyed Map for exactly-once dedup
- Lead-accurate body: 'Starts in N min' (Math.max(1, round(lead/60000)))
- CR-01 pruning: drop entries whose dtstart <= now (event started)
- WR-01 preserved: mark uid sent after all dispatches complete
- Drop gte import; add gt import from drizzle-orm
2026-06-10 12:32:43 -04:00
Lucas Berger 44d336c01b feat(06-03): expose hasRrule on expanded occurrences
- Add hasRrule: boolean to CalendarOccurrence interface
- Capture isRecurring = event.isRecurring() once before the branch
- Set hasRrule: isRecurring in non-recurring push (always false)
- Set hasRrule: isRecurring in recurring push (always true)
- All 10 expand.test.ts tests pass (RED→GREEN)
2026-06-10 11:17:13 -04:00
Lucas Berger d2abb91bd2 feat(06-02): serialize RRULE UNTIL/COUNT and lock FREQ persistence
- Add assembleRruleString() helper (exported) to outboxWorker.ts (D-06)
- Wire UNTIL/COUNT bound assembly into create + update dispatch branches
- Add recurrenceUntil (max 10) + recurrenceCount (int min 1) to outboxPayloadSchema
- Add recurrenceUntil + recurrenceCount to eventFieldsSchema in events.ts
- Series-edit bound change strips existing UNTIL/COUNT via regex before re-apply (Pitfall 3)
- All 39 broker tests pass (RED->GREEN); existing CR-01 none-wins test preserved

Lucas Berger 17756fc523 fix(05-review): NEW-WR-01 emit delete changes when server returns zero events (whole-cache clear)
Pre-capture all currently-cached rows into pendingDeleteRows before the whole-cache
db.delete() when seenUids.length === 0. The existing >0 branch behavior is unchanged.
Adds a regression test verifying onChanges receives one delete change per cached row
on a full-calendar clear.

Lucas Berger 30e9de13f9 feat(05-07): implement eventChangeDispatcher + syncCalendar diff/title/onChanges
- Create eventChangeDispatcher.ts: dispatchEventChange + isMeaningfulChange
- D-04: description-only edits are silent; meaningful fields = title/dtstartUtc/dtstartDate/allDay/location
- D-03: actor excluded via ne() + application-level filter; all subs filtered by userId != actorUserId
- D-13: reads only push_subscriptions from MariaDB — no tsdav/Fastmail I/O
- syncCalendar: add optional onChanges callback; populate title from VEVENT SUMMARY on every upsert
- syncCalendar: pre-upsert SELECT to detect add vs update; track changedFields; prune emits deletes
- poller: pass onChanges with actor=cred.userId (external changes from other member)
- outboxWorker.triggerTargetedResync: pass onChanges with actor=userId (this-member writes)
- All 4 eventChangeDispatcher tests + 14 sync tests GREEN
2026-06-09 22:03:52 -04:00
Lucas Berger b95f671485 feat(05-06): implement reminderScheduler — shared timed 15-min reminder scan
- Create apps/api/src/broker/reminderScheduler.ts:
  - runReminderCheck(now): queries isShared=true + allDay=false events
    with dtstartUtc in [now+14min, now+16min] via calendarEvents→calendars→
    pushSubscriptions cross-join (2 innerJoins; fans out to all subscribers)
  - In-memory sentReminders Set keyed uid:minuteBucket prevents double-fire
    at window boundary (D-06, T-05-18)
  - Per-event and per-subscription try/catch for error isolation (T-05-19)
  - Null title fallback (event.title ?? uid) — handles rows before Plan 05-07
  - Empty shared-calendar set produces zero sends and no crash (D-16)
  - startReminderScheduler(): node-cron 1-min schedule wrapping runReminderCheck
- Wire startReminderScheduler() into index.ts isMainModule() guard after
  startOutboxWorker() and VAPID setVapidDetails (NOTIF-01)
- Tests: 3/3 GREEN (all-day excluded, non-shared excluded, dedup)
2026-06-09 21:38:32 -04:00
Lucas Berger d2ce4e08c7 feat(05-05): hook notifyListChange into list/item mutations (reorder excluded)
- POST /:id/items (item added) → notifyListChange
- PATCH /list-items/:itemId checked/text → notifyListChange; position-only → silent (D-01)
- DELETE /list-items/:itemId → notifyListChange
- PATCH /:id (list rename/share toggle) → notifyListChange
- DELETE /:id (list delete) → notifyListChange
- POST / (list create) → no notification (empty list, D-01 spirit)
- lists.test.ts: 2 new tests prove reorder-silent (position) and check-notifies (NOTIF-02)
- All 59 lists.test.ts assertions GREEN
2026-06-09 21:26:29 -04:00
Lucas Berger 69231043e4 feat(05-05): implement listChangeDispatcher — access-scoped, self-suppressed, coalesced push (NOTIF-02)
- notifyListChange(listId, actorId, windowMs?) wraps coalesceListPush with a
  dispatch closure that resolves actor name + list name from DB, builds
  audience as owner ∪ list_shares MINUS actorId (D-03), and calls
  dispatchPush per accessible subscriber subscription
- D-02 generic copy: '{Actor} made {N} changes to {ListName}' — no item text
- D-03 self-suppression: actorId filtered from audience before subscription load
- T-05-14: audience strictly scoped to list access (owner + list_shares only)
- T-05-15: no item text in notification body
- Empty audience and missing subscriptions are silent no-ops
- Tests: 5/5 GREEN (burst→1 push, self-suppress, access scope, empty audience)
2026-06-09 21:24:48 -04:00
Lucas Berger d816f79271 fix(05-04): wrap setVapidDetails in try/catch to prevent startup crash on bad VAPID key
- Bad/truncated VAPID_PRIVATE_KEY logs a warning instead of crashing the server
- API still starts and serves all other routes; push dispatch fails with a log message
2026-06-09 21:13:58 -04:00
Lucas Berger f6f1374904 feat(05-04): push subscription API + VAPID startup wiring
- Create apps/api/src/routes/push.ts: GET /vapid-public-key, POST /subscription (upsert), DELETE /subscription (user-scoped)
- Wire pushRouter at /api/push in index.ts
- Call webpush.setVapidDetails() in isMainModule() guard before serve()
- Fix broken vi.getMockImplementation scaffold bug in push.test.ts (Rule 1)
- push.test.ts: all 4 tests GREEN
2026-06-09 21:04:16 -04:00
Lucas Berger c1758de05e feat(05-03): implement pushCoalescer — per-(list,actor) sliding debounce (D-01/D-03)
- module-level Map<string, {count, timer}> keyed by ${listId}:${actorId}
- sliding window: each call within window resets timer and increments count
- fires dispatch(listId, actorId, count) once on timer expiry; map entry self-deletes
- actorId passed as second arg so caller can apply excludeUserId=actorId (D-03)
- default windowMs=45000; injected dispatch keeps module pure and testable
2026-06-09 20:58:42 -04:00
Lucas Berger e4170b3823 feat(05-02): implement pushDispatcher — VAPID send + 410/404 prune
- buildPushBody: dual-format payload (iOS 18.4+ declarative + legacy)
- dispatchPush: calls webpush.sendNotification with TTL=300, urgency=normal
- Prunes push_subscriptions row on 410/404 from push service (D-11)
- Logs transient errors with [pushDispatcher] prefix; never throws to caller
- Default import for web-push (CommonJS — Pitfall 7)
2026-06-09 20:54:47 -04:00
Lucas Berger 73fcdaf075 feat(05-01): add push_subscriptions table + calendar_events.title column; VAPID env wiring
- schema.ts: new pushSubscriptions mysqlTable (user_id FK cascade, endpoint unique, p256dh, auth)
- schema.ts: add nullable title varchar(500) to calendarEvents after rawVevent (D-02/NOTIF-01)
- 0003_same_xavin.sql: CREATE TABLE push_subscriptions + ALTER calendar_events ADD title
- migration applied to dev DB via db:generate + db:migrate (NOT db:push per anti-pattern)
- docker-compose.yml: inject VAPID_PUBLIC_KEY/PRIVATE_KEY/SUBJECT into api environment block
- .env.example: document all three VAPID vars with placeholders + generation instructions

Lucas Berger ae115c65ef chore(04-07): commit drizzle migration metadata for 0002 collation migration

drizzle-kit cannot track the migration as applied.
2026-06-09 14:26:52 -04:00
Lucas Berger c0bd6d732d fix(04-07): add owner-only guard for isShared on PATCH /api/lists/:id (T-04-08)
- Immediately after access check, return 403 if patch.isShared !== undefined
  and !access.isOwner — blocks sharees from mutating list_shares
- Guard message: 'Only the list owner can change sharing settings'
- Sharees may still PATCH { name } (rename test stays green)
- Update stale comment: 'Reconcile list_shares on visibility change (owner only)'
- Closes T-04-08 (elevation of privilege) and T-04-05 (shared root cause)
2026-06-09 14:22:48 -04:00
Lucas Berger 9b860617c5 feat(04-07): migrate list_items.rank to COLLATE utf8mb4_bin (LIST-03)
- Add varcharBin customType helper emitting varchar(255) COLLATE utf8mb4_bin
- Replace listItems.rank varchar with varcharBin to carry explicit binary collation
- Generate migration 0002_yielding_mattie_franklin.sql: ALTER TABLE list_items
  MODIFY COLUMN rank varchar(255) COLLATE utf8mb4_bin NOT NULL (additive, no DROP)
- Apply migration via db:migrate (never db:push, per project memory constraint)
- utf8mb4_bin ensures uppercase-prefixed ranks (e.g. Zz) sort before lowercase
  ranks (e.g. a0) in DB ORDER BY, matching JS string order — closes LIST-03 gap
2026-06-09 14:21:42 -04:00
Lucas Berger 690f0b95c0 refactor(04): move rank.test.ts into tests/ mirror dir (convention + dist hygiene)
src/lib/rank.test.ts was the last co-located API test. The API tsconfig excludes
tests/ from the build, so all test files belong there; a test in src/ gets compiled
into dist/ and vitest then runs the stale compiled copy (the source of phantom
'22 todo' and dist sourcemap warnings). Moving it to tests/lib/ matches convention
and leaves zero test files in src/, so the production build no longer emits test
artifacts. Updated rank.test.ts path refs in phase-04 plan docs.

Lucas Berger 1652a68c51 feat(04-06): implement live-sync SSE vertical slice (LIST-04, D-04/D-10/D-11/D-12)
- Wire publishListEvent fan-out in lists.ts after every write mutation (item:added/updated/deleted, list:updated/deleted)
- Add GET /api/sse/lists scoped endpoint in sse.ts: resolveUserId → 401 on null; getAccessibleListIds → subscribe only to accessible channels; 30s heartbeat; cleanup on disconnect (D-04/T-04-01/T-04-02)
- Create useListSSE.ts: bounded-backoff EventSource wrapper (250ms→500ms→1s→2s→4s→cap 8s); MAX_ATTEMPTS=6; withCredentials:true; close-before-retry prevents reconnect storm (Pitfall 3); invalidates ['list', listId] on open (D-10) and on each event; onStateChange('disconnected') after exhaustion (D-11)
- Create LiveSyncIndicator.tsx: connected=green dot; reconnecting=pulsing muted dot + label; disconnected=red dot + 'Updates paused' (role=alert); correct ARIA per UI-SPEC
- Wire useListSSE + LiveSyncIndicator into ListDetail header; retain refetchInterval:30000 polling fallback (D-12)
- All 8 useListSSE tests pass; all 54 API tests pass; both typechecks pass
- playwright-cli: live update confirmed (eggs item added via API appeared in browser without manual refresh)

Lucas Berger ef4b1157b3 test(04-05): server-side reorder ordering + rank precision tests (LIST-03, D-13)
- rank.test.ts: 100-iteration zipper mid-point insert precision test (Pitfall 2);
  rank-between-neighbors contract test; total 10 tests (was 8)
- lists.test.ts: 5 new LIST-03 ordering tests — PATCH position updates only rank
  and GET returns new ASC order; one-row write asserts other items unchanged;
  LWW (D-15): second PATCH overwrites first; T-04-07 two-field position PATCH → 400
- Note: tests use a0–a5 rank range (avoids uppercase ranks that sort differently
  under MariaDB utf8mb4_unicode_ci vs JS lexicographic order)
2026-06-09 13:17:35 -04:00
Lucas Berger 5e3151416c feat(04-04): implement item CRUD endpoints + fractional rank (LIST-02)
- Add rank.ts: rankForAppend/rankBetween wrapping fractional-indexing (D-13)
- Extend listsRouter: POST /:id/items (fractional rank at active-bottom),
  GET /:id/items (rank ASC, access-gated)
- Add listItemsRouter (mounted /api/list-items): PATCH /:itemId per-field LWW
  (exactly-one-field zod refine D-08/T-04-07), DELETE /:itemId delete-wins (D-09)
- Uncheck recomputes rank to active-bottom in same write (Open Question 2)
- All item handlers: access-gate via checkListAccess (T-04-05)
- Plan 06 SSE seam comments at each mutation handler
- All 48 tests green; typecheck passes
