### Phase 18: Auto timezone detection and ability to change timezone
|
||||
|
||||
**Goal:** [To be planned]
|
||||
**Requirements**: TBD
|
||||
**Depends on:** Phase 17
|
||||
**Plans:** 0 plans
|
||||
**Goal:** Make the household timezone an explicit, stored, user-changeable setting — auto-detected from the browser at first run, changeable from the role-gated /admin Settings — and route the server-side all-day "9 AM local" reminder computation through it (replacing the implicit `process.env.TZ` fallback), without touching the already-correct browser-local display/timed-write path.
|
||||
**Requirements**: TBD (decision contract D-01..D-07 from 18-CONTEXT.md)
|
||||
**Depends on:** Phase 10 (admin role + `/admin` Settings + `app_config`); Phase 11 (all-day reminder computation this rewires). Independent of Phase 17. Phase 12 (setup wizard) not required — seeding is self-contained.
|
||||
**Plans:** 4/4 plans complete
|
||||
|
||||
Plans:
|
||||
**Wave 1**
|
||||
|
||||
- [ ] TBD (run /gsd-plan-phase 18 to break down)
|
||||
- [x] 18-01-PLAN.md — TDD: getHouseholdTimezone(db) accessor + isValidIanaTimezone (D-05/D-06)
|
||||
|
||||
**Wave 2** *(blocked on Wave 1 completion)*
|
||||
|
||||
- [x] 18-02-PLAN.md — TDD: admin GET/PUT/seed timezone endpoints on adminRouter, requireAdmin + IANA validation + no-overwrite seed (D-01/D-02/D-03/D-04)
|
||||
- [x] 18-03-PLAN.md — TDD: route all-day reminder TZ at reminderScheduler:247 + outboxWorker:501,607 through the accessor (D-05/D-06/D-07)
|
||||
|
||||
**Wave 3** *(blocked on Wave 2 completion)*
|
||||
|
||||
- [x] 18-04-PLAN.md — PWA Timezone section in /admin Settings (searchable IANA picker + detected-zone seed) + client fns (D-02/D-04)

|

- **Phase 16 added (2026-06-12, /gsd-phase):** CI Dependency Audit, Security Checks & Image Hygiene — extend the Phase 8 Gitea CI workflow with outdated-dependency reporting (`pnpm outdated`), a vulnerability audit (`pnpm audit` at a chosen severity), and a baseline of additional security checks (secret scan / image scan). User requested a 16 integer phase (not a decimal insert) — they've been running independent/CI phases ahead of the admin chain. **Depends on Phase 8; independent of the admin chain (10–12).** Scope still needs definition — run /gsd-discuss-phase 16. Milestone window now Phases 7–16.
|
||||
- **Backlog 999.17 folded into Phase 16 + removed (2026-06-12, /gsd-phase):** the dev/prod image-boundary item (confine `DEV_AUTH_BYPASS` to dev via build/boot-time enforcement; ensure no `.env`/secrets/encryption keys/`DEV_USER` seed/family data ship in published images; CI assertion in the publish job) was pulled into Phase 16 — shared CI surface and overlapping secret/image scanning made a separate phase redundant. The 999.17 backlog entry + its phase dir were **deleted** (not retained-for-history) since the scope now lives in an active phase; this also clears the recycled-number collision with Phase 15's historical "promoted from 999.17" provenance (the markdown-lint item that became Phase 15 had reused 999.17 first).
|
||||
- **Phase 18 added (2026-06-13, /gsd-phase):** Auto timezone detection and ability to change timezone — let the app auto-detect the household timezone and allow changing it. User invoked `/gsd-phase --insert 18` but Phase 18 didn't exist (17 was the last integer phase), so after confirmation it was added as an integer phase at the end of the milestone, not a decimal insert. Motivated by the Phase 11 all-day-reminder dependency on a correct server `TZ` (all-day reminders fire at 9 AM local, computed from `process.env.TZ`). Scope still needs definition — run /gsd-discuss-phase 18. Milestone window now Phases 7–18.
|
||||
- **Phase 19 added (2026-06-15, /gsd-phase):** Local Auth (No-OIDC Mode) — run FamilySync entirely on local DB users with no OIDC, optionally wiring OIDC in later. Deferred from the Phase 12 discuss-phase (the operator runs it this way and wants no-OIDC as a first-class mode). **Depends on Phase 12** — builds on the pre-OIDC local-user foundation introduced there (nullable `oidc_iss`/`oidc_sub` + claimed marker + first-login-claims merge). Scope still needs definition — run /gsd-discuss-phase 19. Milestone window now Phases 7–19.

<objective>
|
||||
Create the single shared accessor and IANA validator that every other Phase 18 task
|
||||
depends on. `getHouseholdTimezone(db)` reads the `household_timezone` key from `app_config`
|
||||
and applies the D-06 fallback chain; `isValidIanaTimezone(tz)` validates an IANA string via
|
||||
`Intl.DateTimeFormat` try/catch.
|
||||
|
||||
Purpose: D-05 mandates ONE accessor so `reminderScheduler.ts` and `outboxWorker.ts` cannot
|
||||
drift; D-06 mandates the exact `process.env.TZ ?? Intl…` fallback so existing all-day tests
|
||||
stay green with no modification. This plan is the foundation both later waves consume.
|
||||
Output: `apps/api/src/lib/householdTimezone.ts` exporting `getHouseholdTimezone` + `isValidIanaTimezone`, fully unit-tested.

# Phase 18 Plan 01: Household Timezone Accessor + IANA Validator Summary
|
||||
|
||||
**Single D-05 accessor `getHouseholdTimezone(db)` reads `household_timezone` from `app_config` with D-06 fallback chain; `isValidIanaTimezone(tz)` validates via `Intl.DateTimeFormat` try/catch (not `supportedValuesOf`)**
|
||||
|
||||
## Performance
|
||||
|
||||
- **Duration:** 2 min
|
||||
- **Started:** 2026-06-15T02:04:31Z
|
||||
- **Completed:** 2026-06-15T02:06:50Z
|
||||
- **Tasks:** 2 (TDD RED + GREEN)
|
||||
- **Files modified:** 2
|
||||
|
||||
## Accomplishments
|
||||
|
||||
- Created `apps/api/src/lib/householdTimezone.ts` exporting `getHouseholdTimezone` and `isValidIanaTimezone`
|
||||
- 11 unit tests cover all 6 required behaviors: stored row, no-row + TZ env, no-row + no-TZ, null row, valid zones, invalid zones
|
||||
- D-06 fallback chain `row?.value ?? process.env.TZ ?? Intl.DateTimeFormat().resolvedOptions().timeZone` reproduced verbatim
|
||||
- TypeScript typecheck (`tsc --noEmit`) clean; full 358-test suite green with no regressions
|
||||
- TDD gate compliance: RED commit (`db0077c`) precedes GREEN commit (`eaceff0`)
|
||||
|
||||
## Task Commits
|
||||
|
||||
1. **Task 1: RED — failing unit tests** - `db0077c` (test)
|
||||
2. **Task 2: GREEN — implement accessor + validator** - `eaceff0` (feat)
|
||||
|
||||
**Plan metadata:** (see final docs commit below)
|
||||
|
||||
## Files Created/Modified
|
||||
|
||||
- `apps/api/src/lib/householdTimezone.ts` — D-05 accessor + IANA validator, exported for broker + admin route consumers
|
||||
- `apps/api/tests/lib/householdTimezone.test.ts` — 11 unit tests for fallback chain and validator
|
||||
|
||||
## Decisions Made
|
||||
|
||||
- `isValidIanaTimezone` uses `Intl.DateTimeFormat(undefined, { timeZone: tz })` try/catch — `Intl.supportedValuesOf('timeZone')` was explicitly avoided because it omits `'UTC'` in some environments (RESEARCH Pitfall 2).
|
||||
- Fallback chain matches the verbatim expression found at `reminderScheduler.ts:247` so the all-day reminder path continues to work unchanged before Plan 02 seeds a stored value.
|
||||
- `db` is accepted as a parameter (not imported from `db/client.js`) to enable clean mock-based unit testing without a live MariaDB connection.
|
||||
|
||||
## Deviations from Plan
|
||||
|
||||
None — plan executed exactly as written.
|
||||
|
||||
## Issues Encountered
|
||||
|
||||
- The vitest global setup requires a MariaDB connection (`global-setup.ts`). Tests need to be run with `DB_HOST=127.0.0.1` when running locally (the `.env` sets `DB_HOST=mariadb` for Docker networking). This is a known dev environment pattern documented in `familysync-dev-stack-setup.md` and has no effect on CI (which uses the service container).
|
||||
|
||||
## Known Stubs
|
||||
|
||||
None — this plan creates a pure utility module with no UI stubs or placeholder data.
|
||||
|
||||
## Threat Flags
|
||||
|
||||
None — no new network endpoints, auth paths, file access patterns, or schema changes were introduced. The accessor is a read-only DB lookup within the trusted server process (T-18-01 disposition: accept).
|
||||
|
||||
## TDD Gate Compliance
|
||||
|
||||
- RED gate: `db0077c` — `test(18-01): add failing tests for household timezone accessor + IANA validator`
|
||||
- GREEN gate: `eaceff0` — `feat(18-01): implement household timezone accessor + IANA validator`
|
||||
- REFACTOR gate: N/A (implementation was clean on first pass)
|
||||
|
||||
## Next Phase Readiness
|
||||
|
||||
- `getHouseholdTimezone` and `isValidIanaTimezone` are the foundation both Plan 18-02 (broker rewire) and Plan 18-03 (admin API + Zod refine) consume.
|
||||
- Plan 18-02 can import `getHouseholdTimezone` from `../lib/householdTimezone.js` to replace the bare `process.env.TZ ?? Intl…` lookups in `reminderScheduler.ts:247` and `outboxWorker.ts:501,607`.
|
||||
- Plan 18-03 can import `isValidIanaTimezone` for the Zod `.refine()` on `PUT /api/admin/config/timezone`.
|
||||
|
||||

<objective>
|
||||
Extend the existing Phase 10 `adminRouter` with three timezone endpoints — GET (read current +
|
||||
isExplicitlySet), PUT (validate + upsert), and a seed endpoint (write only if unset) — all behind
|
||||
the established `requireAdmin` guard.
|
||||
|
||||
Purpose: D-04 puts the timezone behind the role-gated admin surface; D-01 stores it as the single
|
||||
`household_timezone` app_config row; D-02/D-03 add a first-run seed path that never overwrites an
|
||||
already-set value (so Phase 18 is self-contained without Phase 12, and silent drift is impossible).
|
||||
Output: three new routes on `adminRouter` + integration tests proving the access-control and
|
||||
validation boundaries.

## STRIDE Threat Register
|
||||
|
||||
| Threat ID | Category | Component | Disposition | Mitigation Plan |
|
||||
|-----------|----------|-----------|-------------|-----------------|
|
||||
| T-18-03 | Elevation of Privilege | non-admin sets/reads household timezone | mitigate | `adminRouter.use('*', requireAdmin)` (line 41) is the FIRST statement; new routes appended after inherit it. Integration tests assert 403 for a non-admin authenticated user on both GET and PUT (Pitfall 3). Client `isAdmin` is UX-only (Phase 10 D-03); the DB-backed requireAdmin is the real boundary. |
|
||||
| T-18-04 | Tampering | arbitrary/garbage timezone string in PUT body breaks scheduler | mitigate | Zod `.refine(isValidIanaTimezone)` rejects non-IANA strings with 400 before any DB write; `try/catch Intl.DateTimeFormat` is eval-free. Test asserts 'Not/AZone' → 400 and no stored change. |
|
||||
| T-18-05 | Tampering | unauthenticated/first-run seed clobbers an already-set value (silent drift) | mitigate | seed endpoint reads existing value and writes ONLY when unset (D-03); it is also behind requireAdmin. Test asserts a second seed with a different zone leaves the stored value unchanged. |
|
||||
| T-18-06 | Information Disclosure | log/echo of submitted value | accept | Timezone strings are non-sensitive (not credentials/PII — RESEARCH Security Domain); noEchoHook not required. No console.log of bodies added. |
|
||||
| T-18-07 | Injection | app_config key/value write | mitigate | Drizzle parameterizes the insert/upsert; the key is a hard-coded literal `'household_timezone'`; the value is IANA-validated. No string-concatenated SQL. |
|
||||
| T-18-SC | Tampering | npm/pip/cargo installs | mitigate | No new packages this plan (RESEARCH Package Legitimacy Audit: zero installs). |

# Phase 18 Plan 02: Admin Timezone API Endpoints Summary
|
||||
|
||||
**Three role-gated admin endpoints (GET + PUT + seed) added to adminRouter with server-side IANA validation via isValidIanaTimezone and D-03 no-overwrite seed semantics enforced by SELECT-before-INSERT**
|
||||
|
||||
## Performance
|
||||
|
||||
- **Duration:** 3 min
|
||||
- **Started:** 2026-06-15T02:09:38Z
|
||||
- **Completed:** 2026-06-15T02:12:39Z
|
||||
- **Tasks:** 2 (TDD RED + GREEN)
|
||||
- **Files modified:** 2
|
||||
|
||||
## Accomplishments
|
||||
|
||||
- Added `describe('admin timezone config')` to `admin.test.ts` with 8 test cases covering all boundary conditions
|
||||
- Implemented `GET /api/admin/config/timezone`, `PUT /api/admin/config/timezone`, and `POST /api/admin/config/timezone/seed` on the existing `adminRouter`
|
||||
- All routes inherit the line-41 `requireAdmin` guard (Pitfall 9 / T-18-03) — no per-route auth addition needed
|
||||
- `timezoneSchema` uses `isValidIanaTimezone` from Plan 18-01 in a Zod `.refine()` — no `noEchoHook` (T-18-06)
|
||||
- `PUT` uses `onDuplicateKeyUpdate` for a true upsert; `seed` uses SELECT-then-INSERT to enforce D-03 no-overwrite
|
||||
- 25/25 `admin.test.ts` tests pass; 366/366 full API suite green; `tsc --noEmit` clean
|
||||
|
||||
## Task Commits
|
||||
|
||||
1. **Task 1: RED — failing integration tests** - `f109b3c` (test)
|
||||
2. **Task 2: GREEN — implement GET/PUT/seed timezone endpoints** - `3bd6a5d` (feat)
|
||||
|
||||
## Files Created/Modified
|
||||
|
||||
- `apps/api/src/routes/admin.ts` — added appConfig + householdTimezone imports, timezoneSchema, and three new route handlers
|
||||
- `apps/api/tests/routes/admin.test.ts` — added appConfig import + `describe('admin timezone config')` with 8 test cases + per-test afterEach cleanup
|
||||
|
||||
## Decisions Made
|
||||
|
||||
- `timezoneSchema` does NOT use `noEchoHook` because timezone strings are non-sensitive (not credentials/PII); standard `zValidator` error responses are safe (T-18-06 accepted disposition).
|
||||
- `GET /config/timezone` does a direct single-row read (not `getHouseholdTimezone`) so the handler can compute `isExplicitlySet` from `row?.value != null` before deciding whether to invoke the fallback chain — using `getHouseholdTimezone` would discard the "was it stored?" signal.
|
||||
- `POST /api/admin/config/timezone/seed` uses a SELECT-then-INSERT (not `onDuplicateKeyUpdate`) so that D-03 no-overwrite is an explicit code branch, not an implicit race. The test asserts the stored value after a second seed attempt remains unchanged.
|
||||
|
||||
## Deviations from Plan
|
||||
|
||||
None — plan executed exactly as written.
|
||||
|
||||
## Issues Encountered
|
||||
|
||||
- Running `pnpm --filter @familysync/api exec vitest run` requires `DB_ROOT_PASSWORD` from `.env` sourced into the shell (the global-setup provisions `familysync_test` using the root credential). This is the established pattern from quick 260613-ndv and documented in `familysync-dev-stack-setup.md`.
|
||||
|
||||
## Known Stubs
|
||||
|
||||
None — all three endpoints are fully wired to the database. No placeholder data.
|
||||
|
||||
## Threat Flags
|
||||
|
||||
No new threat surface beyond the plan's threat model. All three endpoints are behind `requireAdmin` (T-18-03). IANA validation enforced by `isValidIanaTimezone` (T-18-04). No SQL injection surface — key is a hard-coded literal, value is IANA-validated, Drizzle parameterizes the insert/upsert (T-18-07).
|
||||
|
||||
## TDD Gate Compliance
|
||||
|
||||
- RED gate: `f109b3c` — `test(18-02): add failing integration tests for admin timezone endpoints`
|
||||
- GREEN gate: `3bd6a5d` — `feat(18-02): admin timezone GET/PUT/seed endpoints`
|
||||
- REFACTOR gate: N/A (implementation was clean on first pass)
|
||||
|
||||
## Next Phase Readiness
|
||||
|
||||
- Plan 18-03 (broker rewire) can import `getHouseholdTimezone(db)` from `../lib/householdTimezone.js` to replace the bare `process.env.TZ ?? Intl…` lookups in `reminderScheduler.ts:247` and `outboxWorker.ts:501,607`.
|
||||
- Plan 18-04 (PWA settings UI) can wire to `GET /api/admin/config/timezone` and `PUT /api/admin/config/timezone`. The seed endpoint is also available for the Phase 12 wizard auto-detect flow.

<objective>
|
||||
Rewire the three all-day "9 AM local" timezone lookups — one in `reminderScheduler.ts` (line ~247)
|
||||
and two in `outboxWorker.ts` (lines ~501 and ~607) — to read the stored timezone through the
|
||||
single `getHouseholdTimezone(db)` accessor, replacing the bare
|
||||
`process.env.TZ ?? Intl.DateTimeFormat().resolvedOptions().timeZone` reads.
|
||||
|
||||
Purpose: D-05 makes the stored `household_timezone` the source of truth for the all-day reminder
|
||||
computation, and mandates ONE shared accessor at both sites (no duplicated read/fallback). D-06
|
||||
keeps the exact `process.env.TZ ?? Intl` behavior when nothing is stored, so the existing all-day
|
||||
tests pass unmodified. D-07 is the hard boundary: this plan must NOT touch display/timed-write paths.
|
||||
Output: three rewired call sites + new stored-TZ tests; existing all-day tests green unchanged.

the Drizzle query for events, extend the mock so the household_timezone SELECT resolves to a row

with value 'America/Chicago' (match the accessor's query shape so getHouseholdTimezone returns it).

explicit ISO instant). Do NOT alter the existing process.env.TZ-pinned cases. Run the two suites;

No unvalidated value reaches computeAlertInstantUtc. |
|

| T-18-09 | Tampering (regression) | accidental change to display/timed-write path | mitigate | D-07 boundary enforced as an acceptance criterion: changed-files list must exclude eventDateTime.ts + hydrateEvents.ts; no timed-event serialization touched. Blast radius confined to the all-day branches. |

# Phase 18 Plan 03: Broker Rewire — All-Day TZ Sites Summary
|
||||
|
||||
**Three all-day "9 AM local" reminder call sites in reminderScheduler.ts and outboxWorker.ts now route through `getHouseholdTimezone(db)` instead of the bare `process.env.TZ ?? Intl` expression, making the stored household_timezone the source of truth for all-day reminder fire times (D-05/D-06/D-07)**
|
||||
|
||||
## Performance
|
||||
|
||||
- **Duration:** 28 min
|
||||
- **Started:** 2026-06-15T02:04:00Z
|
||||
- **Completed:** 2026-06-15T02:32:01Z
|
||||
- **Tasks:** 2 (TDD RED + GREEN)
|
||||
- **Files modified:** 4
|
||||
|
||||
## Accomplishments
|
||||
|
||||
- Rewired `reminderScheduler.ts` line 247: `const serverTz = await getHouseholdTimezone(db);`
|
||||
- Rewired `outboxWorker.ts` UPDATE branch (~line 501): `const tz = await getHouseholdTimezone(db);`
|
||||
- Rewired `outboxWorker.ts` CREATE branch (~line 607): `const tz = await getHouseholdTimezone(db);`
|
||||
- Added 4 new RED tests (2 scheduler + 2 outbox) verifying stored 'America/Chicago' drives the 9 AM alert instant; all correctly FAIL before the rewire
|
||||
- Extended test mock infrastructure: `makeAppConfigSelectMock`, `mockThreeQueries`, updated `mockTwoQueries` to add third call for D-06 fallback path, updated `wireMockChain()` in outboxWorker.test.ts for app_config table
|
||||
- All 76 broker tests pass after GREEN commit; TypeScript typecheck (`tsc --noEmit`) clean
|
||||
- D-07 boundary confirmed: `eventDateTime.ts` and `hydrateEvents.ts` not in changed-files list
|
||||
|
||||
## Task Commits
|
||||
|
||||
1. **Task 1: RED — failing stored-TZ all-day tests** - `94daca3` (test)
|
||||
2. **Task 2: GREEN — rewire all three all-day TZ call sites** - `c80845c` (feat)
|
||||
|
||||

- `apps/api/tests/broker/reminderScheduler.test.ts` — `makeAppConfigSelectMock`, `mockThreeQueries` helpers added; `mockTwoQueries` extended to mock the new third db.select(); Plan 18-03 describe block with 2 stored-TZ tests
|
||||
- `apps/api/tests/broker/outboxWorker.test.ts` — `wireMockChain()` extended for app_config table; `wireMockChainWithTz()` helper for D-05 stored-TZ tests; Plan 18-03 describe block with 2 stored-TZ tests (create + update branch)
|
||||
|
||||
## Decisions Made
|
||||
|
||||
- `mockTwoQueries` was extended (not renamed) to avoid updating 20+ call sites. The third mock call returns an empty app_config row (no stored TZ → D-06 fallback), which is transparent to all existing tests that pin `process.env.TZ`.
|
||||
- `mockReset()` added inside `mockTwoQueries` and `mockThreeQueries` to flush any unconsumed `mockReturnValueOnce` entries. Vitest caches mock factory instances across `vi.resetModules()` cycles, so the pending third entry from one test bleeds into the next test's queue without an explicit reset.
|
||||
- The outbox UPDATE branch test uses `mockWhereCalEvents.mockResolvedValue([{etag: 'W/"abc"'}])` after `wireMockChainWithTz` to drive the freshEtagRows path into the all-day VALARM branch (no rawVevent → falls through to the explicit-reminder/allDay condition).
|
||||
|
||||
## Deviations from Plan
|
||||
|
||||
### Auto-fixed Issues
|
||||
|
||||
**1. [Rule 1 - Bug] vi.fn() queue contamination across tests with vi.resetModules()**
|
||||
- **Found during:** Task 1 (RED) — second scheduler test crashed with "innerJoin is not a function"
|
||||
- **Issue:** `vi.clearAllMocks()` does not flush `mockReturnValueOnce` queues. Vitest's mock factory for `vi.mock()` returns the SAME `vi.fn()` instance across module resets, so an unconsumed third entry from the first test bled into the first call slot of the second test — causing `makeAppConfigSelectMock` to be returned where `makeSelectMock` was expected.
|
||||
- **Fix:** Added `db.select.mockReset()` at the start of both `mockTwoQueries` and `mockThreeQueries` to explicitly clear the queue before configuring new once-values.
|
||||
- **Files modified:** `apps/api/tests/broker/reminderScheduler.test.ts`
|
||||
|
||||
**2. [Rule 2 - Missing critical functionality] wireMockChain() in outboxWorker.test.ts didn't handle app_config**
|
||||
- **Found during:** Task 2 (GREEN) — the existing CAL-13 all-day test would have broken after the rewire because `app_config` fell through to `{ where: mockWherePending }`, and `mockWherePending(...)` returns a Promise; calling `.limit(1)` on a Promise throws "limit is not a function"
|
||||
- **Fix:** Extended `wireMockChain()` to handle `app_config` table with a `{ where: fn → {limit: fn} }` chain returning empty rows (D-06 fallback), matching the `getHouseholdTimezone` SELECT chain
|
||||
- **Files modified:** `apps/api/tests/broker/outboxWorker.test.ts`
|
||||
|
||||
**3. [Rule 2 - Missing critical functionality] mockTwoQueries needed a third mock for the new db.select() call**
|
||||
- **Found during:** Task 2 (GREEN) — all 20 existing scheduler tests that call `mockTwoQueries` started failing because `runReminderCheck` now issues a third `db.select()` for `getHouseholdTimezone`; the undefined return caused crashes
|
||||
- **Fix:** Updated `mockTwoQueries` to add a third `mockReturnValueOnce(makeAppConfigSelectMock(null))` returning no row, keeping the D-06 fallback path for all existing tests
|
||||
- **Files modified:** `apps/api/tests/broker/reminderScheduler.test.ts`
|
||||
|
||||
## Known Stubs
|
||||
|
||||
None — all three rewired sites now read from the actual DB through `getHouseholdTimezone(db)`. No placeholder values.
|
||||
|
||||
## Threat Flags
|
||||
|
||||
None — no new network endpoints, auth paths, file access patterns, or schema changes. The three rewired sites are read-only DB lookups within the trusted server process (T-18-08 disposition: mitigate → validated values only reach computeAlertInstantUtc via the Plan 01 accessor that enforces the D-06 fallback chain).
|
||||
|
||||
## TDD Gate Compliance
|
||||
|
||||
- RED gate: `94daca3` — `test(18-03): add failing stored-TZ all-day tests for scheduler + outbox`
|
||||
- GREEN gate: `c80845c` — `feat(18-03): route all-day reminder TZ through stored household_timezone`
|
||||
- REFACTOR gate: N/A (implementation was clean on first pass; deviations were auto-fixed inline)
|
||||

<objective>
|
||||
Add the admin-facing Timezone UI: a searchable IANA picker in the existing `/admin` Settings page,
|
||||
backed by two new client functions that call the Plan 02 endpoints. The picker pre-offers the
|
||||
browser-detected zone so an admin (or the Phase 12 wizard, later) can seed the household timezone in
|
||||
one tap.
|
||||
|
||||
Purpose: D-04 surfaces the change-timezone control in the role-gated admin Settings; D-02 wires the
|
||||
browser detection (`Intl.DateTimeFormat().resolvedOptions().timeZone`) as the suggested value. This
|
||||
is UI + glue against the contract Plan 02 already established and tested.
|
||||
Output: `fetchAdminTimezone`/`setAdminTimezone` in client.ts + a Timezone section in AdminPage.tsx,
|
||||
verified end-to-end with playwright-cli.

## STRIDE Threat Register
|
||||
|
||||
| Threat ID | Category | Component | Disposition | Mitigation Plan |
|
||||
|-----------|----------|-----------|-------------|-----------------|
|
||||
| T-18-11 | Elevation of Privilege | client renders admin UI based on isAdmin flag | accept | Client `isAdmin` is UX-only (Phase 10 D-03); a non-admin who forges the request still hits server-side requireAdmin → 403 (Plan 02 T-18-03). The UI gate is not a security control and is not relied upon as one. |
|
||||
| T-18-12 | Tampering | user types a non-IANA string into the free-text input | mitigate | The datalist offers only valid zones; a manually-typed invalid string is rejected by the server's Zod `isValidIanaTimezone` refine (Plan 02) → 400 surfaced to the user. Client may additionally pre-check before enabling Save, but the server is authoritative. |
|
||||
| T-18-13 | Information Disclosure | XSS via rendered timezone value | mitigate | The value is rendered as plain-text JSX children (no dangerouslySetInnerHTML), consistent with the existing AdminPage convention. IANA strings are constrained anyway. |
|
||||
| T-18-SC | Tampering | npm/pip/cargo installs | mitigate | No new packages this plan (RESEARCH Package Legitimacy Audit: zero installs; picker uses built-in Intl). |

# Phase 18 Plan 04: Admin Timezone UI Summary
|
||||
|
||||
**Searchable IANA timezone picker in /admin Settings — fetchAdminTimezone/setAdminTimezone in client.ts + Timezone section in AdminPage.tsx — verified end-to-end via Playwright with the real 18-02 endpoints**
|
||||
|
||||
## Performance
|
||||
|
||||
- **Duration:** ~15 min
|
||||
- **Started:** 2026-06-15T02:30:00Z
|
||||
- **Completed:** 2026-06-15T02:45:03Z
|
||||
- **Tasks:** 3 (2 auto + 1 playwright-verified checkpoint)
|
||||
- **Files modified/created:** 3
|
||||
|
||||
## Accomplishments
|
||||
|
||||
- Added `AdminTimezoneResponse` interface + `fetchAdminTimezone()` + `setAdminTimezone()` to `apps/pwa/src/api/client.ts`, following the exact pattern of `fetchAdminCalendars` / `setSharedCalendar` (credentials: include, redirect: manual, handleAuthResponse)
|
||||
- Added Timezone section to `AdminPage.tsx` after the Shared Calendar section (with `marginBottom` on the preceding section for spacing)
|
||||
- Timezone section features: 4-state loading/error/data pattern; `<input type="text" list="iana-zones">` + `<datalist>` from `Intl.supportedValuesOf('timeZone')` (guarded); "Using system default" notice when `isExplicitlySet=false`; "Use detected: {zone}" affordance (D-02); disabled Save when pending or unchanged; `timezoneMutation.mutate(tz)` on save; `invalidateQueries(['admin','timezone'])` on success
|
||||
- Created `apps/pwa/e2e/timezone-verify.spec.ts` with 6 desktop Playwright tests — all 6 pass against the live 18-02 API endpoints, including the save + persist across reload flow

3. **Task 3: Playwright timezone round-trip e2e spec** - `3013b53` (test)
|
||||
|
||||
## Files Created/Modified
|
||||
|
||||
- `apps/pwa/src/api/client.ts` — added `AdminTimezoneResponse` interface + `fetchAdminTimezone()` + `setAdminTimezone()` in the `/api/admin/*` section
|
||||
- `apps/pwa/src/routes/AdminPage.tsx` — added `timezoneQuery`, `timezoneMutation`, `timezoneInput` state, `detectedTz`, computed values, `<section aria-label="Timezone">` with IANA picker + affordances + save button
|
||||
- `apps/pwa/e2e/timezone-verify.spec.ts` — new 6-test Playwright spec verifying the full round-trip
|
||||
|
||||
## Decisions Made
|
||||
|
||||
- `AdminTimezoneResponse` type import removed from `AdminPage.tsx` — `@typescript-eslint/no-unused-vars` flagged it (type is inferred from `useQuery` return value, not used as an explicit annotation). ESLint clean.
|
||||
- `<input type="text" list="iana-zones">` has ARIA `combobox` role (not `textbox`) in Chromium — discovered via Playwright page snapshot. Updated e2e locators to `getByRole('combobox')`.
|
||||
- The `timezoneInput` state variable is `null` when the user hasn't typed anything; `effectiveTimezoneInput = timezoneInput ?? storedTimezone` ensures the input shows the stored value on load without the save button enabling prematurely.
|
||||
- After mutation success, `setTimezoneInput(null)` resets the local override so the save button re-disables (effectiveTimezoneInput collapses back to the now-updated storedTimezone).
|
||||
|
||||
## Deviations from Plan
|
||||
|
||||
### Auto-fixed Issues
|
||||
|
||||
**1. [Rule 1 - Bug] Removed unused `AdminTimezoneResponse` import**
|
||||
- **Found during:** Task 2 (ESLint check)
|
||||
- **Issue:** `type AdminTimezoneResponse` was imported but not used as an explicit type annotation; ESLint `no-unused-vars` reported it as an error
|
||||
- **Fix:** Removed from the import line; the type is inferred via `useQuery`
|
||||
- **Files modified:** `apps/pwa/src/routes/AdminPage.tsx`
|
||||
- **Commit:** `43d6689`
|
||||
|
||||
**2. [Rule 3 - Blocking] API dev container serving stale compiled code**
|
||||
- **Found during:** Task 3 (playwright verification)
|
||||
- **Issue:** The Docker container running the API had the pre-Plan-18-02 `dist/routes/admin.js` baked in — the timezone endpoints returned 404. The `--watch dist/index.js` watcher only restarts on `index.js` change, not sub-module changes.
|
||||
- **Fix:** Rebuilt the API (`pnpm --filter @familysync/api build`), then `docker cp` the updated `dist/routes/admin.js`, `dist/lib/householdTimezone.js`, and `dist/index.js` into the container to trigger a restart.
|
||||
- **Files modified:** container-only (not tracked in git)
|
||||
- **Commit:** N/A (operational, not code)
|
||||
|
||||
## Known Stubs
|
||||
|
||||
None — the Timezone section is fully wired to the real `GET /api/admin/config/timezone` and `PUT /api/admin/config/timezone` endpoints (Plan 18-02). No placeholder data.
|
||||
|
||||
## Threat Flags
|
||||
|
||||
No new threat surface beyond the plan's threat model. T-18-11 (client isAdmin gate is UX only), T-18-12 (server validates IANA via Plan 02 Zod refine), T-18-13 (plain-text JSX children, no dangerouslySetInnerHTML).
|
||||
|
||||
## Self-Check: PASSED
|
||||
|
||||
- `apps/pwa/src/api/client.ts` — FOUND (modified, exports fetchAdminTimezone + setAdminTimezone + AdminTimezoneResponse)
|
||||
- `apps/pwa/src/routes/AdminPage.tsx` — FOUND (modified, contains `aria-label="Timezone"`)
|
||||
- `apps/pwa/e2e/timezone-verify.spec.ts` — FOUND (created, 6 desktop tests all pass)
|
||||
- Commit `57424e6` — FOUND
|
||||

|
||||
|
||||
## Pattern Assignments
|
||||
|
||||
### `apps/api/src/lib/householdTimezone.ts` (NEW — utility, DB read)
|
||||
|
||||
**Analog:** `apps/api/src/lib/requireAdmin.ts`
|
||||
|
||||
**Why this analog:** `requireAdmin.ts` is the project's only existing single-purpose lib helper that performs a single Drizzle `SELECT … .limit(1)` lookup from a DB table, matches on a PK-style key, and returns a typed result. The import style, Drizzle usage pattern, and file structure all transfer directly.
|
||||
|
||||
**Imports pattern** (`requireAdmin.ts` lines 17–23):
|
||||
```typescript
|
||||
import '../auth/devBypass.js'; // side-effect import pattern — omit for householdTimezone.ts
|
||||
import type { MiddlewareHandler } from 'hono';
|
||||
import { eq } from 'drizzle-orm';
|
||||
import { db } from '../db/client.js';
|
||||
import { users } from '../db/schema.js';
|
||||
```
|
||||
|
||||
For `householdTimezone.ts`, adapt imports to:
|
||||
```typescript
|
||||
import { eq } from 'drizzle-orm';
|
||||
import type { MySql2Database } from 'drizzle-orm/mysql2';
|
||||
import type * as schema from '../db/schema.js';
|
||||
import { appConfig } from '../db/schema.js';
|
||||
```
|
||||
|
||||
**Core DB read pattern** (`requireAdmin.ts` lines 37–41):
|
||||
```typescript
|
||||
const [row] = await db
|
||||
.select({ isAdmin: users.isAdmin })
|
||||
.from(users)
|
||||
.where(eq(users.id, userId))
|
||||
.limit(1);
|
||||
|
||||
if (!row?.isAdmin) { ... }
|
||||
```
|
||||
|
||||
Adapt to `appConfig` PK lookup:
|
||||
```typescript
|
||||
const [row] = await db
|
||||
.select({ value: appConfig.value })
|
||||
.from(appConfig)
|
||||
.where(eq(appConfig.key, 'household_timezone'))
|
||||
.limit(1);
|
||||
|
||||
return (
|
||||
row?.value ??
|
||||
process.env.TZ ??
|
||||
Intl.DateTimeFormat().resolvedOptions().timeZone
|
||||
);
|
||||
```
|
||||
|
||||
**D-06 fallback chain:** The fallback `process.env.TZ ?? Intl.DateTimeFormat().resolvedOptions().timeZone` mirrors the exact pattern currently at `reminderScheduler.ts:247` and `outboxWorker.ts:501,607`. It must be preserved verbatim as the fallback so existing tests (which pin `process.env.TZ`) continue to pass when no DB row is found.
|
||||
|
||||
**IANA validator (same file):** No analog exists in the codebase — use `try/catch Intl.DateTimeFormat` (no external lib, no `Intl.supportedValuesOf` — see Research Pitfall 2 for why):
|
||||
```typescript
|
||||
export function isValidIanaTimezone(tz: string): boolean {
|
||||
try {
|
||||
Intl.DateTimeFormat(undefined, { timeZone: tz });
|
||||
return true;
|
||||
} catch {
|
||||
return false;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### `apps/api/src/routes/admin.ts` — extend with GET + PUT `/config/timezone`
|
||||
|
||||
**Analog:** `apps/api/src/routes/admin.ts` — existing `GET /calendars` (lines 130–140) and `PUT /calendars/:id/shared` (lines 150–180).
|
||||
|
||||
**Security guard pattern** (`admin.ts` lines 39–41 — DO NOT MOVE):
|
||||
```typescript
|
||||
// Pitfall 9: requireAdmin MUST be the first statement on the router.
|
||||
// All sub-routes are protected — no path can be reached without passing this guard.
|
||||
adminRouter.use('*', requireAdmin);
|
||||
```
|
||||
New routes are appended **after** all existing routes. `adminRouter.use('*', requireAdmin)` already covers them positionally in Hono.
|
||||
|
||||
**Simple GET pattern** (`admin.ts` lines 130–140 — exact model for GET `/config/timezone`):
|
||||
```typescript
|
||||
adminRouter.get('/calendars', async (c) => {
|
||||
const rows = await db
|
||||
.select({
|
||||
id: calendars.id,
|
||||
displayName: calendars.displayName,
|
||||
isShared: calendars.isShared,
|
||||
})
|
||||
.from(calendars);
|
||||
|
||||
return c.json({ calendars: rows });
|
||||
});
|
||||
```
|
||||
|
||||
**Validated PUT pattern** (`admin.ts` lines 150–180 — model for PUT `/config/timezone`):
|
||||
```typescript
|
||||
adminRouter.put('/calendars/:id/shared', async (c) => {
|
||||
const targetId = parseInt(c.req.param('id'), 10);
|
||||
if (isNaN(targetId)) {
|
||||
return c.json({ error: 'Invalid calendar id' }, 400);
|
||||
}
|
||||
// ... DB write ...
|
||||
return c.json({ ok: true }, 200);
|
||||
});
|
||||
```
|
||||
|
||||
For the timezone PUT, use `zValidator` (already imported at line 24) instead of manual param parsing:
|
||||
```typescript
|
||||
adminRouter.put(
|
||||
'/config/timezone',
|
||||
zValidator('json', timezoneSchema),
|
||||
async (c) => {
|
||||
const { timezone } = c.req.valid('json');
|
||||
await db
|
||||
.insert(appConfig)
|
||||
.values({ key: 'household_timezone', value: timezone })
|
||||
.onDuplicateKeyUpdate({ set: { value: timezone } });
|
||||
return c.json({ ok: true }, 200);
|
||||
},
|
||||
);
|
||||
```
|
||||
|
||||
**Zod schema placement** (`admin.ts` lines 47–52 — place new schema alongside existing schemas):
|
||||
```typescript
|
||||
const credentialSchema = z.object({
|
||||
userId: z.number().int().positive(),
|
||||
// ...
|
||||
});
|
||||
```
|
||||
New `timezoneSchema` goes in the same "Zod schema" block:
|
||||
```typescript
|
||||
const timezoneSchema = z.object({
|
||||
timezone: z
|
||||
.string()
|
||||
.min(1)
|
||||
.max(64)
|
||||
.refine(isValidIanaTimezone, { message: 'Invalid IANA timezone identifier' }),
|
||||
});
|
||||
```
|
||||
|
||||
**Import additions needed** (`admin.ts` line 28 — add `appConfig` to schema imports; add `householdTimezone.ts` exports):
|
||||
```typescript
|
||||
import { users, memberCredentials, calendars, appConfig } from '../db/schema.js';
|
||||
import { isValidIanaTimezone, getHouseholdTimezone } from '../lib/householdTimezone.js';
|
||||
```
|
||||
|
||||
**noEchoHook:** NOT needed for timezone routes. Timezone strings are non-sensitive (RESEARCH.md Security Domain). Standard `zValidator` without a custom hook is correct.
|
||||
|
||||
---
|
||||
|
||||
### `apps/api/src/broker/reminderScheduler.ts` — modify line 247
|
||||
|
||||
**Analog:** Same file, same function (`runReminderCheck`).
|
||||
|
||||
**Current pattern at line 247** (verified by research):
|
||||
```typescript
|
||||
const serverTz = process.env.TZ ?? Intl.DateTimeFormat().resolvedOptions().timeZone;
|
||||
```
|
||||
|
||||
**Replacement pattern:**
|
||||
```typescript
|
||||
const serverTz = await getHouseholdTimezone(db);
|
||||
```
|
||||
|
||||
The surrounding call at line 256 (`computeAlertInstantUtc(dtstartDate, leadDays, serverTz)`) is unchanged — `serverTz` remains a `string`, the contract is identical.
|
||||
|
||||
**Import to add** (top of `reminderScheduler.ts`):
|
||||
```typescript
|
||||
import { getHouseholdTimezone } from '../lib/householdTimezone.js';
|
||||
```
|
||||
|
||||
**DB parameter:** `reminderScheduler.ts` already has `db` in scope in the `runReminderCheck` function (Drizzle queries are present elsewhere in the file). Pass it directly to `getHouseholdTimezone(db)`.
|
||||
|
||||
---
|
||||
|
||||
### `apps/api/src/broker/outboxWorker.ts` — modify lines 501 and 607
|
||||
|
||||
**Analog:** Same file, same function (`runOutboxDrain`), two all-day branches.
|
||||
|
||||
**Current pattern at both sites** (verified by research):
|
||||
```typescript
|
||||
// Line 501 (update branch):
|
||||
const tz = process.env.TZ ?? Intl.DateTimeFormat().resolvedOptions().timeZone;
|
||||
const leadDays = fields.reminderLeadMinutes / 1440;
|
||||
allDayAlertInstantUtcUpdate = computeAlertInstantUtc(fields.start, leadDays, tz);
|
||||
|
||||
// Line 607 (create branch):
|
||||
const tz = process.env.TZ ?? Intl.DateTimeFormat().resolvedOptions().timeZone;
|
||||
const leadDays = fields.reminderLeadMinutes / 1440;
|
||||
allDayAlertInstantUtcCreate = computeAlertInstantUtc(fields.start, leadDays, tz);
|
||||
```
|
||||
|
||||
**Replacement at both sites:**
|
||||
```typescript
|
||||
const tz = await getHouseholdTimezone(db);
|
||||
```
|
||||
|
||||
Both sites are in the same `runOutboxDrain` function. If both branches can be reached in a single call, consider computing `tz` once at the top of the all-day processing block and reusing it. The surrounding calls to `computeAlertInstantUtc` are unchanged.
|
||||
|
||||
**Import to add** (top of `outboxWorker.ts`):
|
||||
```typescript
|
||||
import { getHouseholdTimezone } from '../lib/householdTimezone.js';
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### `apps/pwa/src/api/client.ts` — extend with admin timezone functions
|
||||
|
||||
**Analog:** Same file, `fetchAdminCalendars` (lines 445–454) and `setSharedCalendar` (lines 462–469).
|
||||
|
||||
**GET fetch pattern** (`client.ts` lines 445–454 — exact model):
|
||||
```typescript
|
||||
export async function fetchAdminCalendars(): Promise<AdminCalendarsResponse> {
|
||||
const res = await fetch('/api/admin/calendars', {
|
||||
credentials: 'include',
|
||||
redirect: 'manual',
|
||||
});
|
||||
|
||||
handleAuthResponse(res, 'GET /api/admin/calendars');
|
||||
|
||||
return res.json() as Promise<AdminCalendarsResponse>;
|
||||
}
|
||||
```
|
||||
|
||||
Adapt to timezone:
|
||||
```typescript
|
||||
export interface AdminTimezoneResponse {
|
||||
timezone: string;
|
||||
isExplicitlySet: boolean;
|
||||
}
|
||||
|
||||
export async function fetchAdminTimezone(): Promise<AdminTimezoneResponse> {
|
||||
const res = await fetch('/api/admin/config/timezone', {
|
||||
credentials: 'include',
|
||||
redirect: 'manual',
|
||||
});
|
||||
handleAuthResponse(res, 'GET /api/admin/config/timezone');
|
||||
return res.json() as Promise<AdminTimezoneResponse>;
|
||||
}
|
||||
```
|
||||
|
||||
**PUT fetch pattern** (`client.ts` lines 462–469 — model for setAdminTimezone; note `setSharedCalendar` has no body, so also borrow the body pattern from `saveCredential` at lines 429–439):
|
||||
```typescript
|
||||
export async function setAdminTimezone(timezone: string): Promise<void> {
|
||||
const res = await fetch('/api/admin/config/timezone', {
|
||||
method: 'PUT',
|
||||
headers: { 'Content-Type': 'application/json' },
|
||||
credentials: 'include',
|
||||
redirect: 'manual',
|
||||
body: JSON.stringify({ timezone }),
|
||||
});
|
||||
handleAuthResponse(res, 'PUT /api/admin/config/timezone');
|
||||
}
|
||||
```
|
||||
|
||||
**Placement:** Append in the `// ── /api/admin/* ──` section (after line 469), before the `saveMyCredential` function.
|
||||
|
||||
---
|
||||
|
||||
### `apps/pwa/src/routes/AdminPage.tsx` — extend with Timezone section
|
||||
|
||||
**Analog:** Same file, Shared Calendar section (lines 182–288).
|
||||
|
||||
**Query pattern** (`AdminPage.tsx` lines 72–77 — exact model):
|
||||
```typescript
|
||||
const calendarsQuery = useQuery({
|
||||
queryKey: ['admin', 'calendars'],
|
||||
queryFn: fetchAdminCalendars,
|
||||
retry: false,
|
||||
staleTime: 60 * 1000,
|
||||
});
|
||||
```
|
||||
|
||||
Adapt:
|
||||
```typescript
|
||||
const timezoneQuery = useQuery({
|
||||
queryKey: ['admin', 'timezone'],
|
||||
queryFn: fetchAdminTimezone,
|
||||
retry: false,
|
||||
staleTime: 60 * 1000,
|
||||
});
|
||||
```
|
||||
|
||||
**Mutation + invalidation pattern** (`AdminPage.tsx` lines 86–94 — exact model):
|
||||
```typescript
|
||||
const sharedCalMutation = useMutation({
|
||||
mutationFn: (calId: number) => setSharedCalendar(calId),
|
||||
onSuccess: () => {
|
||||
void queryClient.invalidateQueries({ queryKey: ['admin', 'calendars'] });
|
||||
void queryClient.invalidateQueries({ queryKey: ['events'] });
|
||||
setSelectedCalendarId(null);
|
||||
},
|
||||
});
|
||||
```
|
||||
|
||||
Adapt:
|
||||
```typescript
|
||||
const timezoneMutation = useMutation({
|
||||
mutationFn: (tz: string) => setAdminTimezone(tz),
|
||||
onSuccess: () => {
|
||||
void queryClient.invalidateQueries({ queryKey: ['admin', 'timezone'] });
|
||||
},
|
||||
});
|
||||
```
|
||||
|
||||
**Section structure** (`AdminPage.tsx` lines 182–288 — use as template):
|
||||
```tsx
|
||||
<section aria-label="Shared Calendar">
|
||||
<div style={sectionLabelStyle}>Shared Calendar</div>
|
||||
{/* loading, error, empty, data states */}
|
||||
</section>
|
||||
```
|
||||
|
||||
New section follows the same four-state pattern (loading, error, empty/unset, data). Reuse `sectionLabelStyle` (defined at line 40–47) without modification. Add `marginBottom: 'var(--space-8, 32px)'` to the preceding section to separate from the new one.
|
||||
|
||||
**Save button pattern** (`AdminPage.tsx` lines 244–285):
|
||||
```tsx
|
||||
<button
|
||||
type="button"
|
||||
disabled={saveDisabled}
|
||||
onClick={() => { /* mutate */ }}
|
||||
style={{
|
||||
background: saveDisabled ? 'var(--color-border, #E2E4E9)' : 'var(--color-member-0, #4A90D9)',
|
||||
color: '#ffffff',
|
||||
border: 'none',
|
||||
cursor: saveDisabled ? 'default' : 'pointer',
|
||||
fontSize: 'var(--text-label-size, 13px)',
|
||||
fontWeight: 600,
|
||||
minHeight: '44px',
|
||||
minWidth: '44px',
|
||||
padding: '0 var(--space-6, 24px)',
|
||||
borderRadius: 'var(--space-1, 4px)',
|
||||
fontFamily: 'var(--font-family-base)',
|
||||
transition: 'background 0.15s ease',
|
||||
}}
|
||||
>
|
||||
{mutation.isPending ? 'Saving…' : 'Save'}
|
||||
</button>
|
||||
```
|
||||
|
||||
**IANA picker UX — no library:** Use `<input type="text" list="iana-zones">` + `<datalist>` populated from `Intl.supportedValuesOf('timeZone')`. This is consistent with the project's hand-rolled inline-styles convention (no component library). Initial value of the input: `timezoneQuery.data?.timezone ?? ''` (shows stored value or fallback). The `isExplicitlySet` flag from the API response can display a subtle "using system default" note when `false`.
|
||||
|
||||
**Import additions for AdminPage.tsx:**
|
||||
```typescript
|
||||
import {
|
||||
fetchAdminTimezone,
|
||||
setAdminTimezone,
|
||||
type AdminTimezoneResponse,
|
||||
} from '../api/client.js';
|
||||
```
|
||||

||||
### Admin Route Guard
|
||||
**Source:** `apps/api/src/routes/admin.ts` line 41
|
||||
**Apply to:** All new routes in `admin.ts` (inherited automatically — no per-route addition needed)
|
||||
```typescript
|
||||
adminRouter.use('*', requireAdmin);
|
||||
// This single middleware statement covers ALL routes registered on adminRouter,
|
||||
// including appended routes. Do not add requireAdmin inline to individual handlers.
|
||||
```
|
||||
|
||||
### Drizzle App Config Upsert (MariaDB)
|
||||
**Source:** Established pattern from `admin.ts` + Drizzle mysql2 dialect (verified in RESEARCH.md)
|
||||
**Apply to:** PUT `/config/timezone` handler and the seeding helper
|
||||
```typescript
|
||||
await db
|
||||
.insert(appConfig)
|
||||
.values({ key: 'household_timezone', value: timezone })
|
||||
.onDuplicateKeyUpdate({ set: { value: timezone } });
|
||||
```
|
||||
Note: `app_config.key` is the PK (`varchar(128).primaryKey()`), so this is a true upsert. `drizzle-orm@0.45.2` + `mysql2@3.22.4` support this syntax natively.
|
||||
|
||||
### Drizzle Single-Row PK Lookup
|
||||
**Source:** `apps/api/src/lib/requireAdmin.ts` lines 37–41
|
||||
**Apply to:** `getHouseholdTimezone` helper and GET `/config/timezone` handler
|
||||
```typescript
|
||||
const [row] = await db
|
||||
.select({ value: appConfig.value })
|
||||
.from(appConfig)
|
||||
.where(eq(appConfig.key, 'household_timezone'))
|
||||
.limit(1);
|
||||
// row is undefined when no row exists — use optional chaining: row?.value
|
||||
```
|
||||
|
||||
### Client Auth Response Handling
|
||||
**Source:** `apps/pwa/src/api/client.ts` lines 51–58 (`handleAuthResponse`)
|
||||
**Apply to:** All new fetch wrappers in `client.ts`
|
||||
```typescript
|
||||
function handleAuthResponse(res: Response, label: string): void {
|
||||
if (res.type === 'opaqueredirect' || res.status === 401) {
|
||||
throw new SessionExpiredError();
|
||||
}
|
||||
if (!res.ok) {
|
||||
throw new Error(`${label} failed: ${res.status}`);
|
||||
}
|
||||
}
|
||||
// Usage: call immediately after fetch, before res.json()
|
||||
handleAuthResponse(res, 'GET /api/admin/config/timezone');
|
||||
```
|
||||
|
||||
### TanStack Query + Mutation + Invalidation
|
||||
**Source:** `apps/pwa/src/routes/AdminPage.tsx` lines 64–94
|
||||
**Apply to:** New Timezone section in `AdminPage.tsx`
|
||||
```typescript
|
||||
// useQueryClient() already called at top of AdminPage — no additional call needed
|
||||
const timezoneQuery = useQuery({ queryKey: ['admin', 'timezone'], queryFn: fetchAdminTimezone, retry: false, staleTime: 60 * 1000 });
|
||||
const timezoneMutation = useMutation({
|
||||
mutationFn: (tz: string) => setAdminTimezone(tz),
|
||||
onSuccess: () => void queryClient.invalidateQueries({ queryKey: ['admin', 'timezone'] }),
|
||||
});
|
||||
```

# Phase 18 — Plan Index & Coverage Audit
|
||||
|
||||
**Created:** 2026-06-15
|
||||
**Plans:** 4 (3 waves)
|
||||
**Mode:** standard · TDD mode ON · MVP off
|
||||
|
||||
---
|
||||
|
||||
## Wave Structure
|
||||
|
||||
| Wave | Plans | Autonomous | Files (disjoint per wave) |
|
||||
|------|-------|------------|----------------------------|
|
||||
| 1 | 18-01 (accessor + IANA validator, TDD) | yes | `lib/householdTimezone.ts` (+test) |
|
||||
| 2 | 18-02 (admin endpoints, TDD), 18-03 (broker wiring, TDD) | yes, yes | 02: `routes/admin.ts` (+test); 03: `broker/reminderScheduler.ts` + `broker/outboxWorker.ts` (+tests) — no overlap with 02 |
|
||||
| 3 | 18-04 (PWA picker UI) | no (human-verify checkpoint) | `pwa/api/client.ts`, `pwa/routes/AdminPage.tsx` |
|
||||
|
||||
Dependency rationale: 02 and 03 both depend only on the Wave-1 accessor and touch disjoint files →
|
||||
parallel in Wave 2. 04 depends on the 02 endpoint contract → Wave 3.

## Multi-Source Coverage Audit
|
||||
|
||||
### GOAL (ROADMAP Phase 18 goal)
|
||||
"Auto-detect the household timezone and allow changing it" → COVERED: detection seed (D-02, Plans 02 seed
|
||||
endpoint + 04 detected-zone affordance); change (D-04, Plans 02 PUT + 04 picker); behavioral wiring
|
||||
(D-05, Plan 03).
|
||||
|
||||
### REQ (phase_req_ids from REQUIREMENTS.md)
|
||||
No REQ-IDs are mapped to Phase 18 in ROADMAP.md (confirmed: "Requirements: TBD"). Per the planning
|
||||
context, the D-01..D-07 decision set is the coverage contract — see CONTEXT below. Not a gap.
|
||||
|
||||
### RESEARCH (18-RESEARCH.md features/constraints)
|
||||
- Single accessor `getHouseholdTimezone` + IANA validator → Plan 01.
|
||||
- GET/PUT endpoints on adminRouter, no new router → Plan 02.
|
||||
- Seed endpoint, additive/non-blocking (Phase 12 not yet executed) → Plan 02.
|
||||
- Rewire reminderScheduler:247 + outboxWorker:501,607 → Plan 03.
|
||||
- PWA picker, no new package, Intl-based → Plan 04.
|
||||
- No new npm installs (Package Legitimacy Audit: zero) → honored across all plans; T-18-SC = no-op.
|
||||
|
||||
### CONTEXT (D-01..D-07 — the trackable decision contract)
|
||||
|
||||
| Decision | Covered by | Where |
|
||||
|----------|-----------|-------|
|
||||
| D-01 single household app_config key `household_timezone` | Plan 01 (key literal), Plan 02 (upsert) | accessor + endpoints |
|
||||
| D-02 browser-detect + seed at first run | Plan 02 (seed endpoint), Plan 04 (detected-zone affordance) | endpoints + UI |
|
||||
| D-03 no auto-overwrite after seed | Plan 02 (seed writes only if unset) | seed endpoint |
|
||||
| D-04 change via role-gated /admin Settings | Plan 02 (requireAdmin endpoints), Plan 04 (Timezone section) | endpoints + UI |
|
||||
| D-05 stored TZ = source of truth, single accessor at both scheduler sites | Plan 01 (accessor), Plan 03 (both sites route through it) | accessor + broker |
|
||||
| D-06 fallback chain when unset | Plan 01 (verbatim fallback), Plan 03 (existing tests stay green) | accessor + broker |
|
||||
| D-07 do not touch display/timed-write path | Plan 03 + Plan 04 (boundary as acceptance criterion) | broker + UI |
|
||||
|
||||
**No unplanned items.** Deferred Ideas (per-member timezones; driving display/timed off stored TZ) are
|
||||
correctly absent from all plans.

# Phase 18: Auto Timezone Detection and Ability to Change Timezone - Research
|
||||
|
||||
**Researched:** 2026-06-15
|
||||
**Domain:** Server-side timezone configuration, Admin settings, IANA validation
|
||||
**Confidence:** HIGH (all findings grounded in actual codebase inspection)

|
||||
## User Constraints (from CONTEXT.md)
|
||||
|
||||
### Locked Decisions
|
||||
|
||||
- **D-01:** Single **household-wide** timezone, stored in `app_config` (key `household_timezone`, IANA string value). No per-member `users.timezone` column.
|
||||
- **D-02:** Auto-detect the browser IANA timezone (`Intl.DateTimeFormat().resolvedOptions().timeZone`) and use it to **seed** the stored value during the Phase 12 setup wizard / first run.
|
||||
- **D-03:** After seeding, timezone changes **only** via the settings UI. No auto-overwrite on later login/detection differences. (Optional drift notice allowed, not required.)
|
||||
- **D-04:** Surface the timezone in the existing **role-gated `/admin` Settings** (Phase 10 `requireAdmin` boundary) and seed it from the **Phase 12 setup wizard**.
|
||||
- **D-05:** The stored timezone becomes the **source of truth for the server-side all-day "9 AM local" reminder computation** (`reminderScheduler.ts`, `outboxWorker.ts`), replacing the bare `process.env.TZ ?? Intl…` lookup at those sites.
|
||||
- **D-06:** **Fallback chain when `household_timezone` is unset**: fall back to `process.env.TZ ?? Intl.DateTimeFormat().resolvedOptions().timeZone`.
|
||||
- **D-07:** Display rendering and timed-event write serialization stay **browser-local** and unchanged. Must NOT touch `eventDateTime.ts` or `hydrateEvents.ts`.
|
||||
|
||||
### Claude's Discretion
|
||||
|
||||
- Timezone picker UX: a searchable IANA dropdown. Validate the value is a real IANA zone before storing.
|
||||
- Exact `app_config` key name and the read/cache strategy for the stored value in the scheduler/outbox (e.g. read-per-run vs cached).
|
||||
- Whether to show a non-blocking "detected zone differs" notice on login (allowed per D-03, not required).
|
||||
|
||||
### Deferred Ideas (OUT OF SCOPE)
|
||||
|
||||
- Per-member timezones (would add `users.timezone` + per-row scheduler logic).
|
||||
- Driving display/timed reminders off the stored tz (deliberately excluded, D-07).
|
||||
</user_constraints>
|
||||

|
||||
|
||||
## Summary
|
||||
|
||||
Phase 18 is a tightly scoped wiring change: one new `app_config` key (`household_timezone`) becomes the source of truth for the server-side all-day reminder computation, replacing two bare `process.env.TZ ?? Intl…` lookups in `reminderScheduler.ts` (line 247) and `outboxWorker.ts` (lines 501 and 607). A single shared accessor helper reads this key from the DB with the D-06 fallback, ensuring both scheduler sites stay synchronized. No new npm packages are required. No schema migration is needed — `app_config` already exists and accepts arbitrary keys as additive rows.
|
||||
|
||||
The admin surface (Phase 10 `adminRouter`, `requireAdmin`, `AdminPage.tsx`) already provides the exact pattern to extend: add GET + PUT endpoints to `/api/admin/config/timezone` following the same route file, client API function, TanStack Query + mutation pattern already present in `AdminPage.tsx`. The IANA validation uses a Zod `.refine()` with a `try/catch` on `Intl.DateTimeFormat` — no external library needed.
|
||||
|
||||
Phase 12 (Initial Setup Wizard) has NOT been executed yet. Its status is `draft` (only a UI spec exists, no route code). The `household_timezone` seeding must therefore be planned as a Phase 18 deliverable that is additive/optional — a standalone seed endpoint (`POST /api/admin/config/timezone/seed`) or an inline seed in an early Phase 18 task — so Phase 18 is not blocked. When Phase 12 eventually executes, it calls the same write endpoint.
|
||||
|
||||
**Primary recommendation:** Extract a `getHouseholdTimezone(db): Promise<string>` helper in `apps/api/src/lib/householdTimezone.ts`, add GET/PUT endpoints on `adminRouter`, extend `AdminPage.tsx` with a new Timezone section, and wire both scheduler sites through the helper. No new dependencies. Read-per-run (not cached) for correctness.

## Architectural Responsibility Map
|
||||
|
||||
| Capability | Primary Tier | Secondary Tier | Rationale |
|
||||
|------------|-------------|----------------|-----------|
|
||||
| Store household timezone | Database / Storage | API | `app_config` table; PK-keyed key/value row |
|
||||
| Read timezone for scheduling | API / Backend | — | `reminderScheduler.ts` + `outboxWorker.ts` run server-side; DB read at each tick |
|
||||
| Validate IANA timezone string | API / Backend | Browser / Client | Server validates before write (real boundary); browser validates before submit (UX) |
|
||||
| Admin read/write timezone | API / Backend | Frontend Server | `requireAdmin` is server enforced; client `isAdmin` is UX only (Phase 10 D-03) |
|
||||
| Browser timezone detection | Browser / Client | — | `Intl.DateTimeFormat().resolvedOptions().timeZone` is client-side only |
|
||||
| Display rendering, timed-event serialization | Browser / Client | — | Unchanged by D-07; remains browser-local |

## Standard Stack
|
||||
|
||||
### Core (all already installed — no new packages)
|
||||
|
||||
| Library | Version | Purpose | Why Standard |
|
||||
|---------|---------|---------|--------------|
|
||||
| drizzle-orm | 0.45.2 | DB read/write for `app_config` | Already in stack; `eq()` + `.select()` / `.insert().onDuplicateKeyUpdate()` for upsert |
|
||||
| zod | 3.25.x | IANA string validation | Already in stack; `.refine()` with `Intl.DateTimeFormat` try/catch |
|
||||
| @hono/zod-validator | 0.8.0 | Route body validation | Already wired in `adminRouter` |
|
||||
| hono | 4.12.23 | Route handlers | Already in stack; extend `adminRouter` |
|
||||
| @tanstack/react-query | 5.101.0 | PWA data fetch + mutation | Already in `AdminPage.tsx` |
|
||||
| Native `Intl` API | Node 22 built-in | IANA validation + browser detection | No package needed |
|
||||
|
||||
**No new npm installs required for this phase.**
|
||||
|
||||
### Supporting
|
||||
|
||||
| Library | Version | Purpose | When to Use |
|
||||
|---------|---------|---------|-------------|
|
||||
| `mysql2` (via drizzle) | 3.22.4 | Underlying driver | Used implicitly by drizzle; no direct use needed |
|
||||
|
||||
### Alternatives Considered
|
||||
|
||||
| Instead of | Could Use | Tradeoff |
|
||||
|------------|-----------|----------|
|
||||
| `try/catch Intl.DateTimeFormat` | `Intl.supportedValuesOf('timeZone')` membership check | `supportedValuesOf` excludes 'UTC', 'GMT', 'Etc/UTC' (verified in Node 22) — those ARE valid. The try/catch approach accepts all valid zones including UTC variants [VERIFIED: Node 22 runtime test] |
|
||||
| Read-per-run DB read | In-memory TTL cache | Cache adds invalidation complexity; read-per-run means changes propagate within 60s (one scheduler tick) with no restart; PK lookup is negligible cost |
|
||||
| Extend existing `adminRouter` | New router/file | The existing pattern (`adminRouter.get/put`, `requireAdmin` first, `zValidator`) is correct and established — extending is the right choice |
|
||||

|
||||
|
||||
## Package Legitimacy Audit
|
||||
|
||||
This phase installs **no new packages**. All capabilities use packages already in the monorepo.
|
||||
|
||||
**Packages removed due to [SLOP] verdict:** none
|
||||
**Packages flagged as suspicious [SUS]:** none (no new installs)
|
||||
|
||||
> Note: `hono` was flagged `SUS` by the registry scanner due to a recent publish date, but it is a locked stack choice from CLAUDE.md and already installed. This flag does not apply to existing dependencies.

|
||||
```
|
||||
|
||||
### Pattern 1: Stored TZ Accessor Helper (getHouseholdTimezone)
|
||||
|
||||
**What:** A single exported async function that reads `household_timezone` from `app_config` and applies the D-06 fallback chain.
|
||||
|
||||
**When to use:** Called at the start of each all-day processing block in `reminderScheduler.ts` and `outboxWorker.ts`. Not called for timed events (those don't use local time).
|
||||
|
||||
**Example:**
|
||||
```typescript
|
||||
// apps/api/src/lib/householdTimezone.ts
|
||||
import { eq } from 'drizzle-orm';
|
||||
import type { MySql2Database } from 'drizzle-orm/mysql2';
|
||||
import type * as schema from '../db/schema.js';
|
||||
import { appConfig } from '../db/schema.js';
|
||||
|
||||
/**
|
||||
* Read the household timezone from app_config.
|
||||
* D-06 fallback: process.env.TZ ?? Intl.DateTimeFormat().resolvedOptions().timeZone
|
||||
* (same fallback the bare lookups used before Phase 18).
|
||||
*
|
||||
* Read-per-call so timezone changes propagate within one scheduler tick
|
||||
* without requiring a worker restart.
|
||||
*/
|
||||
export async function getHouseholdTimezone(
|
||||
db: MySql2Database<typeof schema>,
|
||||
): Promise<string> {
|
||||
const [row] = await db
|
||||
.select({ value: appConfig.value })
|
||||
.from(appConfig)
|
||||
.where(eq(appConfig.key, 'household_timezone'))
|
||||
.limit(1);
|
||||
|
||||
return (
|
||||
row?.value ??
|
||||
process.env.TZ ??
|
||||
Intl.DateTimeFormat().resolvedOptions().timeZone
|
||||
);
|
||||
}
|
||||
|
||||
/**
|
||||
* Validate that a string is an IANA timezone accepted by the JS engine.
|
||||
* try/catch on Intl.DateTimeFormat covers 'UTC', 'GMT', 'Etc/UTC', and all
|
||||
* 418 named IANA zones. Intl.supportedValuesOf('timeZone') is NOT used because
|
||||
* it excludes 'UTC' and 'Etc/*' variants in Node 22 and Chrome.
|
||||
*/
|
||||
export function isValidIanaTimezone(tz: string): boolean {
|
||||
try {
|
||||
Intl.DateTimeFormat(undefined, { timeZone: tz });
|
||||
return true;
|
||||
} catch {
|
||||
return false;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Usage in reminderScheduler.ts (line 247 replacement):**
|
||||
```typescript
|
||||
// BEFORE (line 247):
|
||||
const serverTz = process.env.TZ ?? Intl.DateTimeFormat().resolvedOptions().timeZone;
|
||||
|
||||
// AFTER:
|
||||
const serverTz = await getHouseholdTimezone(db);
|
||||
```
|
||||
|
||||
**Usage in outboxWorker.ts (lines 501 and 607 replacement):**
|
||||
```typescript
|
||||
// BEFORE (line 501):
|
||||
const tz = process.env.TZ ?? Intl.DateTimeFormat().resolvedOptions().timeZone;
|
||||
|
||||
// AFTER:
|
||||
const tz = await getHouseholdTimezone(db);
|
||||
```
|
||||
|
||||
### Pattern 2: Admin Endpoint (GET + PUT /api/admin/config/timezone)
|
||||
|
||||
**What:** Two new routes on `adminRouter`, following the exact pattern of existing admin routes. GET reads the current value (with fallback), PUT validates + upserts.
|
||||
|
||||
**When to use:** Admin settings UI reads/writes.
|
||||
|
||||
**Example:**
|
||||
```typescript
|
||||
// In apps/api/src/routes/admin.ts (extend existing file)
|
||||
|
||||
const timezoneSchema = z.object({
|
||||
timezone: z.string().refine(isValidIanaTimezone, { message: 'Invalid IANA timezone' }),
|
||||
});
|
||||
|
||||
// GET /api/admin/config/timezone
|
||||
adminRouter.get('/config/timezone', async (c) => {
|
||||
const [row] = await db
|
||||
.select({ value: appConfig.value })
|
||||
.from(appConfig)
|
||||
.where(eq(appConfig.key, 'household_timezone'))
|
||||
.limit(1);
|
||||
|
||||
const timezone =
|
||||
row?.value ??
|
||||
process.env.TZ ??
|
||||
Intl.DateTimeFormat().resolvedOptions().timeZone;
|
||||
|
||||
return c.json({ timezone, isExplicitlySet: row?.value != null });
|
||||
});
|
||||
|
||||
// PUT /api/admin/config/timezone
|
||||
adminRouter.put(
|
||||
'/config/timezone',
|
||||
zValidator('json', timezoneSchema),
|
||||
async (c) => {
|
||||
const { timezone } = c.req.valid('json');
|
||||
|
||||
await db
|
||||
.insert(appConfig)
|
||||
.values({ key: 'household_timezone', value: timezone })
|
||||
.onDuplicateKeyUpdate({ set: { value: timezone } });
|
||||
|
||||
return c.json({ ok: true });
|
||||
},
|
||||
);
|
||||
```
|
||||
|
||||
### Pattern 3: PWA TanStack Query + Mutation (AdminPage extension)
|
||||
|
||||
**What:** A new Timezone section in `AdminPage.tsx`, mirroring the existing Shared Calendar section pattern exactly.
|
||||
|
||||
**Example:**
|
||||
```typescript
|
||||
// In apps/pwa/src/api/client.ts (extend existing file)
|
||||
export interface AdminTimezoneResponse {
|
||||
timezone: string;
|
||||
isExplicitlySet: boolean;
|
||||
}
|
||||
|
||||
export async function fetchAdminTimezone(): Promise<AdminTimezoneResponse> {
|
||||
const res = await fetch('/api/admin/config/timezone', {
|
||||
credentials: 'include',
|
||||
redirect: 'manual',
|
||||
});
|
||||
handleAuthResponse(res, 'GET /api/admin/config/timezone');
|
||||
return res.json() as Promise<AdminTimezoneResponse>;
|
||||
}
|
||||
|
||||
export async function setAdminTimezone(timezone: string): Promise<void> {
|
||||
const res = await fetch('/api/admin/config/timezone', {
|
||||
method: 'PUT',
|
||||
headers: { 'Content-Type': 'application/json' },
|
||||
credentials: 'include',
|
||||
redirect: 'manual',
|
||||
body: JSON.stringify({ timezone }),
|
||||
});
|
||||
handleAuthResponse(res, 'PUT /api/admin/config/timezone');
|
||||
}
|
||||
```
|
||||
|
||||
```typescript
|
||||
// In AdminPage.tsx (new section, same query/mutation pattern as calendarsQuery)
|
||||
const timezoneQuery = useQuery({
|
||||
queryKey: ['admin', 'timezone'],
|
||||
queryFn: fetchAdminTimezone,
|
||||
retry: false,
|
||||
staleTime: 60 * 1000,
|
||||
});
|
||||
|
||||
const timezoneMutation = useMutation({
|
||||
mutationFn: (tz: string) => setAdminTimezone(tz),
|
||||
onSuccess: () => {
|
||||
void queryClient.invalidateQueries({ queryKey: ['admin', 'timezone'] });
|
||||
},
|
||||
});
|
||||
```
|
||||
|
||||
**IANA Picker UX — no new library:** A `<select>` with a `<datalist>` or a controlled `<input>` + filtered `<select>` using `Intl.supportedValuesOf('timeZone')` on the browser side. The project uses no component library (hand-rolled inline styles, project convention). A simple searchable `<select>` is sufficient:
|
||||
|
||||
```typescript
|
||||
// Browser-side IANA list for the picker (client only)
|
||||
const IANA_ZONES = typeof Intl.supportedValuesOf === 'function'
|
||||
? Intl.supportedValuesOf('timeZone')
|
||||
: [];
|
||||
// Note: browser Intl.supportedValuesOf works in Chrome 93+, Safari 14.1+, Firefox 91+.
|
||||
// The 'UTC' omission from the list is benign on the browser side — server validates with
|
||||
// try/catch, so a manually-typed 'UTC' still passes. The picker's filtered <select>
|
||||
// shows continent/ocean zones only; the text input allows override.
|
||||
```
|
||||
|
||||
A `<input type="text" list="iana-zones">` + `<datalist id="iana-zones">` with all zone options is the lowest-friction approach for a non-technical user — they can type their city name and browser autocompletes from the datalist.
|
||||
|
||||
### Pattern 4: Phase 12 Wizard Seeding (additive, non-blocking)
|
||||
|
||||
**What:** A standalone seed write so Phase 18 can be executed without waiting for Phase 12.
|
||||
|
||||
**When to use:** Phase 18 executor includes a Wave 0 task: add a `POST /api/admin/config/timezone/seed` endpoint (or inline in the wizard's `complete` endpoint in Phase 12). The seeding endpoint writes `household_timezone` only if it is not already set (no-overwrite-if-set guard per D-03).
|
||||
|
||||
**Recommendation:** Make Phase 18 include a seeding helper in the API. Phase 12 (when executed) calls the same PUT endpoint or uses the helper directly in the `/setup/complete` handler.
|
||||
|
||||
```typescript
|
||||
// Seeding write (wizard or any first-run path)
|
||||
// Only write if not already set (no silent overwrite per D-03)
|
||||
async function seedTimezoneIfUnset(db, browserTz: string) {
|
||||
const [existing] = await db
|
||||
.select({ value: appConfig.value })
|
||||
.from(appConfig)
|
||||
.where(eq(appConfig.key, 'household_timezone'))
|
||||
.limit(1);
|
||||
if (!existing?.value) {
|
||||
await db
|
||||
.insert(appConfig)
|
||||
.values({ key: 'household_timezone', value: browserTz })
|
||||
.onDuplicateKeyUpdate({ set: { value: browserTz } });
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Anti-Patterns to Avoid
|
||||
|
||||
- **Modifying `eventDateTime.ts` or `hydrateEvents.ts`:** D-07 is a hard boundary. The browser-local write/display path was deliberately fixed in earlier phases. Any touch to these files is out of scope and risks regression.
|
||||
- **Using `Intl.supportedValuesOf('timeZone')` for server-side validation:** It excludes 'UTC' and 'Etc/*' variants in Node 22 and Chrome. Use `try/catch Intl.DateTimeFormat` instead.
|
||||
- **Caching the timezone value in memory:** Read-per-call in the scheduler and outbox is correct. In-memory caching requires invalidation signaling and doesn't meaningfully improve a 60s interval.
|
||||
- **Installing a timezone-list package:** The project convention is hand-rolled, no new dependencies. `Intl.supportedValuesOf('timeZone')` is available in all target browsers and Node 22.
|
||||
- **Auto-overwriting `household_timezone` on login:** D-03 forbids this. Only the settings UI write and the first-run seed may write this key.
|
||||
- **Putting the seeding call on the `/api/me` route (or OIDC callback):** This would trigger on every login, violating D-03 (no auto-overwrite after seeding).
|
||||

|
||||
## Don't Hand-Roll
|
||||
|
||||
| Problem | Don't Build | Use Instead | Why |
|
||||
|---------|-------------|-------------|-----|
|
||||
| IANA timezone validation | Custom regex or static list | `try/catch Intl.DateTimeFormat()` | Engine-validated, handles all variants including UTC/Etc, zero deps |
|
||||
| IANA zone list for picker | npm `moment-timezone`, `tzdata` | `Intl.supportedValuesOf('timeZone')` | Built-in to Node 22 and modern browsers, 418 zones, no package needed |
|
||||
| Key/value DB upsert | Manual SELECT + conditional INSERT | Drizzle `.insert().onDuplicateKeyUpdate()` | MariaDB-compatible upsert pattern; Drizzle mysql dialect handles it correctly |
|
||||
|
||||
**Key insight:** All complexity for this phase lives in the wiring, not the algorithms. `computeAlertInstantUtc` is already correct; the phase only changes what timezone string is passed to it.
|
||||
|
||||

|
||||
|
||||
## Confirmed Code Touchpoints (verified by file inspection)
|
||||
|
||||
### `reminderScheduler.ts` — line 247 (confirmed, CONTEXT hint was accurate)
|
||||
|
||||
```typescript
|
||||
// Line 247 (VERIFIED by grep):
|
||||
const serverTz = process.env.TZ ?? Intl.DateTimeFormat().resolvedOptions().timeZone;
|
||||
// Line 256: passed to computeAlertInstantUtc(dtstartDate, leadDays, serverTz)
|
||||
```
|
||||
|
||||
**Contract:** `serverTz` is a `string` passed as the third argument to `computeAlertInstantUtc`. The function signature is `computeAlertInstantUtc(eventDateStr: string, leadDays: number, tz: string): Date` (`vevent.ts` line 240). The contract is tz-string-in, unchanged. Phase 18 only changes the value of `serverTz`.
|
||||
|
||||
### `outboxWorker.ts` — lines 501 and 607 (confirmed, both sites)
|
||||
|
||||
```typescript
|
||||
// Line 501 (update branch, allDay+explicit reminder):
|
||||
const tz = process.env.TZ ?? Intl.DateTimeFormat().resolvedOptions().timeZone;
|
||||
const leadDays = fields.reminderLeadMinutes / 1440;
|
||||
allDayAlertInstantUtcUpdate = computeAlertInstantUtc(fields.start, leadDays, tz);
|
||||
|
||||
// Line 607 (create branch, allDay+reminder):
|
||||
const tz = process.env.TZ ?? Intl.DateTimeFormat().resolvedOptions().timeZone;
|
||||
const leadDays = fields.reminderLeadMinutes / 1440;
|
||||
allDayAlertInstantUtcCreate = computeAlertInstantUtc(fields.start, leadDays, tz);
|
||||
```
|
||||
|
||||
Both sites are in the `runOutboxDrain` function. Both are in all-day event branches. The CONTEXT hint (§~501, §~607) is accurate.
|
||||
|
||||
### `vevent.ts` — `computeAlertInstantUtc` signature (lines 240–343, confirmed)
|
||||
|
||||
```typescript
|
||||
// Line 240 (VERIFIED):
|
||||
export function computeAlertInstantUtc(eventDateStr: string, leadDays: number, tz: string): Date
|
||||
```
|
||||
|
||||
The function is a pure computation: event date string, lead days, tz string → UTC Date. The tz argument is used via `Intl.DateTimeFormat` internally. **No change to this function.** Phase 18 only changes what is passed as `tz`.
|
||||
|
||||
### `schema.ts` — `appConfig` table (line 282, confirmed)
|
||||
|
||||
```typescript
|
||||
// Line 282 (VERIFIED):
|
||||
export const appConfig = mysqlTable('app_config', {
|
||||
key: varchar('key', { length: 128 }).primaryKey(),
|
||||
value: text('value'), // nullable
|
||||
updatedAt: timestamp('updated_at').defaultNow().onUpdateNow(),
|
||||
});
|
||||
```
|
||||
|
||||
The `household_timezone` key is a new additive row — no migration needed. The existing `0001_famous_mad_thinker.sql` migration already created this table.
|
||||
|
||||
### `admin.ts` (Phase 10 route) — confirmed extend pattern
|
||||
|
||||
Current routes: `GET /members`, `POST /credentials`, `GET /calendars`, `PUT /calendars/:id/shared`. All gated by `adminRouter.use('*', requireAdmin)` as first statement. New endpoints extend the same file and inherit the guard.
|
||||
|
||||
### `AdminPage.tsx` — confirmed extend pattern
|
||||
|
||||
- Uses `useQuery(['admin', 'calendars'], ...)` + `useMutation` + `useQueryClient` + `invalidateQueries` pattern.
|
||||
- New Timezone section follows the same structure as the Shared Calendar section.
|
||||
- `sectionLabelStyle` is defined at top of file and reused — new section reuses it.
|
||||
|
||||
### Phase 12 status — NOT YET EXECUTED
|
||||
|
||||
Confirmed by `STATE.md` (current position is Phase 13, Phase 12 only has `12-UI-SPEC.md` under `.planning/phases/12-initial-setup-wizard/`). No setup route code exists in `apps/api/src/` or `apps/pwa/src/`. Phase 18 must be self-contained: the timezone seeding must work without Phase 12.
|
||||
|
||||

|
||||
|
||||
## Common Pitfalls
|
||||
|
||||
### Pitfall 1: Both Scheduler Sites Must Use the Same Accessor
|
||||
|
||||
**What goes wrong:** Separately duplicating the DB read in both `reminderScheduler.ts` and `outboxWorker.ts`. If you add the read inline in both files separately, future changes must be made in two places, and they can drift.
|
||||
|
||||
**Why it happens:** The CONTEXT.md says "both must route through the same stored-value accessor" — this is easy to forget if planning treats the two files as independent tasks.
|
||||
|
||||
**How to avoid:** Define `getHouseholdTimezone(db)` in `apps/api/src/lib/householdTimezone.ts` in Wave 0 / Plan 1. Both scheduler files import from there.
|
||||
|
||||
**Warning signs:** If a plan task says "add `getHouseholdTimezone`" to both `reminderScheduler.ts` and `outboxWorker.ts` without a shared lib — wrong approach.
|
||||
|
||||
### Pitfall 2: Intl.supportedValuesOf Excludes 'UTC'
|
||||
|
||||
**What goes wrong:** Server-side Zod validation uses `Intl.supportedValuesOf('timeZone').includes(tz)` — then a user who types 'UTC' gets a 400 error even though it is a valid timezone.
|
||||
|
||||
**Why it happens:** The MDN docs say `supportedValuesOf('timeZone')` works, but the spec excludes 'UTC', 'GMT', 'Etc/UTC', and all `Etc/*` identifiers from the return value in Node 22 and Chrome (verified with runtime test: `Intl.supportedValuesOf('timeZone').includes('UTC')` → `false`).
|
||||
|
||||
**How to avoid:** Use `try/catch Intl.DateTimeFormat(undefined, { timeZone: val })` in the Zod `.refine()`. This accepts all valid zones including UTC variants.
|
||||
|
||||
**Warning signs:** Unit test for 'UTC' input fails with 400 from the validation endpoint.
|
||||
|
||||
### Pitfall 3: requireAdmin Must Remain First Middleware Statement
|
||||
|
||||
**What goes wrong:** Adding new routes before `adminRouter.use('*', requireAdmin)` or in a position where the middleware doesn't cover them.
|
||||
|
||||
**Why it happens:** The middleware is positional in Hono — routes registered before `use('*', ...)` are not covered.
|
||||
|
||||
**How to avoid:** New endpoints are appended after the existing routes in `admin.ts`. The `adminRouter.use('*', requireAdmin)` is already the first statement (line 41) and covers all routes registered on `adminRouter` regardless of append order in Hono.
|
||||
|
||||
**Warning signs:** Test for non-admin user on new endpoint returns 200 instead of 403.
|
||||
|
||||
### Pitfall 4: Drizzle `onDuplicateKeyUpdate` Syntax for MariaDB
|
||||
|
||||
**What goes wrong:** Using wrong Drizzle syntax for upsert, or trying `drizzle-kit push` (forbidden — D-Task5-DDL).
|
||||
|
||||
**Why it happens:** Drizzle's mysql dialect supports `.insert().onDuplicateKeyUpdate({ set: { ... } })`. The `app_config` key is the PK, so inserting with an existing key is an upsert. No migration needed for a new key; only a data write.
|
||||
|
||||
**How to avoid:** Use the exact Drizzle pattern: `db.insert(appConfig).values({...}).onDuplicateKeyUpdate({ set: { value: ... } })`. Verified compatible with `drizzle-orm@0.45.2` + `mysql2@3.22.4` (MariaDB wire-compatible).
|
||||
|
||||
**Warning signs:** Drizzle throws `Duplicate entry` error instead of updating.
|
||||
|
||||
### Pitfall 5: Existing All-Day Scheduler Tests Pin `process.env.TZ`
|
||||
|
||||
**What goes wrong:** After Phase 18 wires `getHouseholdTimezone(db)`, the existing all-day tests in `reminderScheduler.test.ts` that pin `process.env.TZ = 'America/New_York'` rely on the old bare `process.env.TZ` read. When the code switches to a DB read, the mock DB must return the expected timezone, otherwise the test reads `null` → falls back to `process.env.TZ` → still works.
|
||||
|
||||
**Why it's actually safe:** The D-06 fallback chain preserves `process.env.TZ` when `household_timezone` is unset. As long as the test's mock DB returns no `household_timezone` row (which it won't, since tests mock the DB to return only event rows), the fallback to `process.env.TZ` kicks in — tests continue to pass without modification. This is the backward-compat guarantee.
|
||||
|
||||
**How to verify:** Existing all-day tests pass without any modification (fallback fires). New Phase 18 tests for the DB-stored case mock the DB to also return the `app_config` row.
|
||||
|
||||
**Warning signs:** Existing all-day tests fail after Phase 18 wiring — indicates fallback isn't implemented correctly.
|
||||
|
||||
### Pitfall 6: Phase 12 Seeding Must Not Overwrite After First Set
|
||||
|
||||
**What goes wrong:** Phase 12 (or any seeding path) unconditionally writes `household_timezone` on every setup/login, violating D-03.
|
||||
|
||||
**How to avoid:** The seed write must check if the key is already set before writing. Use a SELECT + conditional INSERT pattern, or use `.onDuplicateKeyUpdate` only with a no-op set guard: `INSERT ... ON DUPLICATE KEY UPDATE value = IF(value IS NULL, VALUES(value), value)`. Simpler: SELECT first, only INSERT if `row?.value` is null.

|
||||
## Code Examples
|
||||
|
||||
### IANA validation — production-safe, UTC-inclusive
|
||||
|
||||
```typescript
|
||||
// Source: Node 22 runtime verification (2026-06-15)
|
||||
// try/catch accepts UTC, GMT, Etc/UTC, Etc/GMT, and all 418 continent/ocean zones
|
||||
export function isValidIanaTimezone(tz: string): boolean {
|
||||
try {
|
||||
Intl.DateTimeFormat(undefined, { timeZone: tz });
|
||||
return true;
|
||||
} catch {
|
||||
return false;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Zod schema for PUT /api/admin/config/timezone body
|
||||
|
||||
```typescript
|
||||
// Source: zod.dev official docs (.refine() pattern) + project CLAUDE.md (zod 3.24.x)
|
||||
const timezoneSchema = z.object({
|
||||
timezone: z
|
||||
.string()
|
||||
.min(1)
|
||||
.max(64)
|
||||
.refine(isValidIanaTimezone, { message: 'Invalid IANA timezone identifier' }),
|
||||
});
|
||||
```
|
||||
|
||||
### Drizzle upsert for app_config (MariaDB compatible)
|
||||
|
||||
```typescript
|
||||
// Source: drizzle-orm mysql2 dialect, verified pattern in existing codebase
|
||||
import { appConfig } from '../db/schema.js';
|
||||
|
||||
await db
|
||||
.insert(appConfig)
|
||||
.values({ key: 'household_timezone', value: timezone })
|
||||
.onDuplicateKeyUpdate({ set: { value: timezone } });
|
||||
```
|
||||
|
||||
### Browser timezone seeding (PWA side, first-run only)
|
||||
|
||||
```typescript
|
||||
// Called once during Phase 12 wizard complete step (or Phase 18 standalone seed)
|
||||
// D-03: only seed if not yet set (server enforces IF NOT EXISTS logic)
|
||||
const browserTz = Intl.DateTimeFormat().resolvedOptions().timeZone;
|
||||
await setAdminTimezone(browserTz); // Server applies no-overwrite guard
|
||||
```
|
||||
|
||||

|
||||
|
||||
## State of the Art
|
||||
|
||||
| Old Approach | Current Approach | When Changed | Impact |
|
||||
|--------------|------------------|--------------|--------|
|
||||
| `process.env.TZ ?? Intl…` bare lookup in scheduler | Stored `app_config.household_timezone` + fallback | Phase 18 | Timezone correct across Docker restarts where TZ env is unset |
|
||||
| No user-facing timezone setting | Admin UI picker + stored value | Phase 18 | Admin can fix "9 AM local" if it fires at wrong time |
|
||||
|
||||
**Deprecated/outdated:**
|
||||
- Direct `process.env.TZ` reads in scheduler/outbox for all-day logic: these sites are replaced by `getHouseholdTimezone(db)` in Phase 18.
|
||||
|
||||
---
|
||||
|
||||
## Phase 12 Dependency Analysis
|
||||
|
||||
Phase 12 (Initial Setup Wizard) has status `draft` — only `12-UI-SPEC.md` exists. No routes, no PWA wizard route code. The Phase 12 UI spec describes a 5-step wizard where Step 5 ("Calendar Credential") calls `POST /api/setup/complete`. The timezone seeding would naturally go here but is not yet implemented.
|
||||
|
||||
**Phase 18 must be self-contained.** Recommended approach: Phase 18 adds a seed-timezone endpoint or admin-writable PUT endpoint that Phase 12 can later call. The AdminPage.tsx timezone section (Phase 18 deliverable) also shows the browser-detected zone as the pre-filled value in the picker, so an admin can confirm or change it on first login — covering the seeding requirement without needing Phase 12.
|
||||
|
||||
**Ordering:** Phase 18 executes before Phase 12. Phase 12 can call `PUT /api/admin/config/timezone` (or the seeding helper) during the wizard's `POST /api/setup/complete` to pre-populate from the browser.
|
||||
|
||||
---
|
||||
|
||||
## Environment Availability
|
||||
|
||||
This phase is code/config-only (new routes + lib helper + PWA section). No external service dependencies beyond the existing MariaDB and API server.
|
||||
|
||||
| Dependency | Required By | Available | Version | Fallback |
|
||||
|------------|------------|-----------|---------|----------|
|
||||
| MariaDB (app_config table) | DB read/write | Already in stack | MariaDB 11 (Unraid) | — |
|
||||
| Node 22 `Intl` API | IANA validation | Built-in | Node 22.22.3 (confirmed) | — |
|
||||
| Browser `Intl.DateTimeFormat` | Browser detection | Chrome 93+, Safari 14.1+, Firefox 91+ | Built-in | — |

### Phase Requirements → Test Map
|
||||
|
||||
| Req ID | Behavior | Test Type | Automated Command | File Exists? |
|
||||
|--------|----------|-----------|-------------------|-------------|
|
||||
| D-05/D-06 | `getHouseholdTimezone` returns stored value when set | Unit | `vitest run tests/lib/householdTimezone.test.ts` | No — Wave 0 |
|
||||
| D-05/D-06 | `getHouseholdTimezone` falls back to `process.env.TZ` when unset | Unit | same | No — Wave 0 |
|
||||
| D-05/D-06 | `getHouseholdTimezone` falls back to `Intl` when both unset | Unit | same | No — Wave 0 |
|
||||
| D-05 | `reminderScheduler` all-day branch uses stored TZ | Unit (mock DB) | `vitest run tests/broker/reminderScheduler.test.ts` | Exists (extend) |
|
||||
| D-05 | `outboxWorker` all-day branch uses stored TZ | Unit (mock DB) | `vitest run tests/broker/outboxWorker.test.ts` | Exists (extend) |
|
||||
| IANA validation | Invalid zone → 400 from PUT endpoint | Integration | `vitest run tests/routes/admin.test.ts` | Exists (extend) |

|
||||
| End-to-end | Admin sets TZ → next 9AM reminder fires in new zone | Manual | `playwright-cli` (Chromium) | No — verify step |
|
||||
|
||||
### Existing Test Infrastructure Notes
|
||||
|
||||
- `tests/broker/reminderScheduler.test.ts` lines 656–729: existing all-day tests pin `process.env.TZ = 'America/New_York'` in `beforeEach`. After Phase 18 wiring, these tests mock the DB to return only event rows (not app_config rows), so `getHouseholdTimezone` finds no stored value and falls back to `process.env.TZ` — tests continue to pass **without modification** (D-06 backward compat).
|
||||
- New Phase 18 all-day tests that verify stored TZ behavior: mock the DB to return `{ key: 'household_timezone', value: 'America/Chicago' }` and assert firing at 9 AM Chicago time.
|
||||
- `tests/routes/admin.test.ts`: integration tests hit real MariaDB (`familysync_test` DB). New timezone tests follow same `beforeEach`/`afterEach` DB cleanup pattern.
|
||||
|
||||
### Sampling Rate
|
||||
|
||||
- **Per task commit:** `pnpm --filter @familysync/api exec vitest run tests/lib/householdTimezone.test.ts`
|
||||
- **Per wave merge:** `pnpm --filter @familysync/api test && pnpm --filter @familysync/pwa test`
|
||||
- **Phase gate:** Full suite green (all 244+ existing tests pass) + manual admin change-TZ round-trip via `playwright-cli`
|
||||
|
||||
### Wave 0 Gaps
|
||||
|
||||
- [ ] `apps/api/tests/lib/householdTimezone.test.ts` — covers D-05/D-06 accessor + fallback chain + IANA validator
|
||||
- [ ] Extend `apps/api/tests/routes/admin.test.ts` with GET/PUT timezone endpoint tests (403 non-admin, IANA validation, round-trip)
|
||||
- [ ] Extend `apps/api/tests/broker/reminderScheduler.test.ts` with stored-TZ all-day test

## Security Domain
|
||||
|
||||
> `security_enforcement: true` (default) in `.planning/config.json`.
|
||||
|
||||
### Applicable ASVS Categories
|
||||
|
||||
| ASVS Category | Applies | Standard Control |
|
||||
|---------------|---------|-----------------|
|
||||
| V2 Authentication | No | (OIDC already handled by `@hono/oidc-auth`) |
|
||||
| V3 Session Management | No | (session cookie already handled) |
|
||||
| V4 Access Control | Yes | `requireAdmin` middleware (DB-enforced, not client flag) |
|
||||
| V5 Input Validation | Yes | Zod `.refine(isValidIanaTimezone)` on PUT body |
|
||||
| V6 Cryptography | No | No new crypto; timezone is a non-sensitive plain string |
|
||||
|
||||
### Known Threat Patterns for This Stack
|
||||
|
||||
| Pattern | STRIDE | Standard Mitigation |
|
||||
|---------|--------|---------------------|
|
||||
| Non-admin sets timezone via direct API call | Elevation of Privilege | `requireAdmin` middleware is FIRST statement on `adminRouter`; server 403 before any handler |
|
||||
| Invalid/malicious timezone string in PUT body | Tampering | Zod `.refine(isValidIanaTimezone)` rejects before DB write; `try/catch Intl.DateTimeFormat` is safe (no eval) |
|
||||
| Timezone injection causing log pollution | Information Disclosure | IANA strings are limited to standard zone identifiers; Intl validation rejects anything else |
|
||||
|
||||
**Note:** Timezone strings are non-sensitive (not credentials, not PII). No special sanitization beyond IANA validation is required. The `noEchoHook` pattern from credentials is NOT needed here.

## Assumptions Log
|
||||
|
||||
| # | Claim | Section | Risk if Wrong |
|
||||
|---|-------|---------|---------------|
|
||||
| A1 | Read-per-run DB lookup is negligible overhead for a 60s interval scheduler | Architecture Patterns | If DB is slow (unlikely for PK lookup), could add a few ms to each tick. Impact: none on correctness. |
|
||||
| A2 | `Intl.DateTimeFormat` try/catch accepts all valid IANA zones in target browsers (iOS Safari 16.4+) | Standard Stack | iOS < 16.4 outside scope (CLAUDE.md min); tested in Node 22 [VERIFIED: runtime test] |
|
||||
| A3 | Phase 12 setup wizard will call `PUT /api/admin/config/timezone` when executed | Phase 12 section | If Phase 12 uses a different mechanism, Phase 18's seeding logic may conflict. Low risk: Phase 12 spec shows a `POST /api/setup/complete` pattern that can call the helper. |
|
||||

||||
**If this table is empty:** All claims in this research were verified or cited.
|
||||
|
||||
---
|
||||
|
||||
## Open Questions
|
||||
|
||||
1. **Should Phase 18 include a seed endpoint accessible during the Phase 12 wizard?**
|
||||
- What we know: Phase 12 `POST /api/setup/complete` will need to write `household_timezone`. The PUT endpoint on `adminRouter` is admin-gated (require admin), which may not be available at wizard-complete time (first admin not yet set).
|
||||
- What's unclear: Is `requireAdmin` already satisfied at wizard-complete time (the first user becomes admin during the wizard)?
|
||||
- Recommendation: Phase 10 `auth/user.ts` line 114 shows "first user → admin" logic; if the wizard calls `setup/complete` after promoting the user to admin, the PUT endpoint is accessible. Planner should confirm the admin-promotion timing relative to the timezone seed call. If promotion happens in the same `setup/complete` handler, the PUT endpoint is available.
|
||||
|
||||
2. **Should the AdminPage timezone picker pre-fill with the detected browser timezone as a hint?**
|
||||
- What we know: D-02 says "auto-detect from browser at setup." The AdminPage is post-login.
|
||||
- What's unclear: Whether showing a "detected: America/New_York — click to use" affordance is in scope.
|
||||
- Recommendation: This is in Claude's Discretion (CONTEXT.md). The planner should treat it as optional UX polish — the base requirement is a searchable picker with save, not a detection affordance. The picker's initial value shows the current stored timezone (or the fallback zone). A pre-fill is nice but not required.

# Phase 18: Code Review Fix Report
|
||||
|
||||
**Fixed at:** 2026-06-15T07:43:30Z
|
||||
**Source review:** .planning/phases/18-auto-timezone-detection-and-ability-to-change-timezone/18-REVIEW.md
|
||||
**Iteration:** 1
|
||||
|
||||
**Summary:**
|
||||
- Findings in scope: 5 (2 Warning + 3 Info; fix_scope = all)
|
||||
- Fixed: 5
|
||||
- Skipped: 0
|
||||
|
||||
All in-scope findings were fixed. The full API test suite (375 tests across 28
|
||||
files) and `tsc --noEmit` pass cleanly. No PWA files were touched, so PWA tests
|
||||
were not run.
|
||||
|
||||
## Fixed Issues
|
||||
|
||||
### WR-01: Empty-but-set `process.env.TZ` defeats the D-06 fallback and yields an invalid zone
|
||||
|
||||
**Files modified:** `apps/api/src/lib/householdTimezone.ts`, `apps/api/tests/lib/householdTimezone.test.ts`
|
||||
**Commit:** d168da7
|
||||
**Applied fix:** Extracted the D-06 fallback into a new `resolveHouseholdTimezone(storedValue)`
|
||||
helper that `.trim()`s candidate values and treats empty/whitespace-only values
|
||||
(both the stored value and `process.env.TZ`) as absent so they fall through to the
|
||||
`Intl` resolved zone, instead of relying on `??` which only short-circuits on
|
||||
null/undefined. `getHouseholdTimezone` now delegates to it. Added RED→GREEN unit
|
||||
tests for `TZ=''` and `TZ=' '` proving fall-through to the Intl zone. Updated the
|
||||
doc comment to reflect the now-enforced "non-empty" guarantee.
|
||||
|
||||
### WR-02: Seed `seeded` flag can misreport under a real concurrent race
|
||||
|
||||
**Files modified:** `apps/api/src/routes/admin.ts`, `apps/api/tests/routes/admin.test.ts`
|
||||
**Commit:** 93217b5
|
||||
**Applied fix:** Replaced the pre-flight `SELECT` + conditional
|
||||
`onDuplicateKeyUpdate` with a single `INSERT IGNORE` and derive `seeded` from the
|
||||
result's `affectedRows`. **Note (deviation from the review's literal suggestion):**
|
||||
the review proposed `seeded: insertResult.affectedRows === 1` against the existing
|
||||
`onDuplicateKeyUpdate(value=value)`. I empirically probed this MariaDB and found
|
||||
`onDuplicateKeyUpdate(value=value)` returns `affectedRows: 1` for BOTH a fresh insert
|
||||
and a no-op duplicate, so it cannot distinguish them. `INSERT IGNORE` reliably returns
|
||||
`affectedRows: 1` on insert and `0` when the row already exists (ignored, value
|
||||
preserved — D-03), which is what makes the derived flag accurate under a concurrent
|
||||
race. The `timezone` is interpolated via drizzle's parameterized `sql` template (bound
|
||||
param, not string concatenation) and is already IANA-validated by `timezoneSchema`.
|
||||
Corrected the overstated in-code comment. Added a test asserting `seeded:false` for a
|
||||
row pre-inserted directly (bypassing the endpoint), which only an INSERT-derived flag
|
||||
can satisfy.
|
||||
|
||||
### IN-01: `getHouseholdTimezone` re-runs the same `app_config` SELECT the GET handler just issued
|
||||
|
||||
**Files modified:** `apps/api/src/routes/admin.ts`
|
||||
**Commit:** 692fe2a
|
||||
**Applied fix:** The `GET /config/timezone` handler now reuses the row it already
|
||||
SELECTed by calling `resolveHouseholdTimezone(row?.value ?? null)` instead of
|
||||
`getHouseholdTimezone(db)`, removing the redundant second `app_config` round-trip on
|
||||
the unset path. Behavior unchanged.
|
||||
|
||||
### IN-02: D-06 fallback policy is duplicated between the accessor and the GET handler
|
||||
|
||||
**Files modified:** `apps/api/src/lib/householdTimezone.ts`, `apps/api/src/routes/admin.ts`
|
||||
**Commit:** d168da7 (accessor), 692fe2a (handler)
|
||||
**Applied fix:** Centralized the fallback policy in the new `resolveHouseholdTimezone`
|
||||
helper (single source of truth, D-05 intent). The GET handler derives
|
||||
`isExplicitlySet` from row presence and routes the value through the same helper, so
|
||||
the WR-01 empty-`TZ` guard lives in exactly one place and the two sites cannot drift.
|
||||
|
||||
### IN-03: `outboxWorker` may read the stored timezone twice within one drain cycle
|
||||
|
||||
**Files modified:** `apps/api/src/broker/outboxWorker.ts`
|
||||
**Commit:** 1fb431e
|
||||
**Applied fix:** Added a lazy per-drain-cycle `TimezoneResolver` (mirroring the
|
||||
existing `clientCache` thread-through, IN-01) created in `runOutboxDrain` and passed
|
||||
into `dispatchRow`. The UPDATE and CREATE all-day branches now share a single
|
||||
`app_config` read. The read stays lazy — cycles with no all-day work never touch the
|
||||
DB. Behavior unchanged; all 39 outboxWorker tests pass.

## Summary
|
||||
|
||||
Re-review (iteration 2 of the --auto fix loop) of Phase 18 timezone changes after fixes for
|
||||
WR-01 (empty/whitespace `process.env.TZ` fallback guard), WR-02 (`seeded` derived from
|
||||
`INSERT IGNORE` affectedRows), and IN-01/02/03 (reuse fetched row on GET unset path; centralized
|
||||
D-06 fallback; per-drain-cycle timezone memoization). All previously-raised findings are resolved.
|
||||
No new Critical or Warning defects were introduced.
|
||||
|
||||
## Narrative Findings (AI reviewer)
|
||||
|
||||
No Critical, Warning, or actionable Info findings remain. Verification notes below.
|
||||
|
||||
### Verification of applied fixes
|
||||
|
||||
- **WR-01 — empty/whitespace TZ fallthrough (`apps/api/src/lib/householdTimezone.ts:49-61`).**
|
||||
Correct. `resolveHouseholdTimezone` trims the stored value first; a set-but-blank stored value
|
||||
falls through, then `process.env.TZ?.trim()` rejects `''`/`' '` and falls through to the Intl
|
||||
zone. The normal stored-value path (`stored` truthy after trim) and the unset path are both
|
||||
preserved. D-05 (single accessor — both `reminderScheduler.ts:250` and `outboxWorker.ts:391`
|
||||
route through `getHouseholdTimezone`) and D-06 (stored → env.TZ → Intl chain) still hold. New
|
||||
unit tests pin both empty and whitespace cases (`householdTimezone.test.ts:101-117`).
|
||||
|
||||
- **WR-02 — `seeded` derived from affectedRows (`apps/api/src/routes/admin.ts:251-269`).**
|
||||
Correct. The endpoint runs a single `INSERT IGNORE` and derives `seeded` from
|
||||
`affectedRows === 1`. On MariaDB an ignored duplicate yields `affectedRows === 0`, so the flag
|
||||
is accurate even under a genuine concurrent race — only the racer whose row actually wrote gets
|
||||
`seeded:true`. D-03 no-overwrite is preserved (duplicate is silently ignored, value untouched).
|
||||
The IANA value is validated by `timezoneSchema.refine(isValidIanaTimezone)` before the handler
|
||||
runs and is bound as a parameterized value via drizzle's `sql` template (not string-
|
||||
concatenated); column identifiers use `sql.identifier` — no injection. `seeded:false` accuracy
|
||||
is pinned by the pre-inserted-row test (`admin.test.ts:821-846`) and the idempotent-race test
|
||||
(`:783-815`).
|
||||
|
||||
- **IN-01/02 — GET unset path reuses the fetched row (`apps/api/src/routes/admin.ts:200-213`).**
|
||||
Correct. The GET handler SELECTs once, computes `isExplicitlySet` from `row?.value != null`, and
|
||||
passes the same `row?.value ?? null` to the centralized `resolveHouseholdTimezone`. No second
|
||||
app_config round-trip; the D-06 fallback policy lives in exactly one function. Semantics
|
||||
unchanged: unset → fallback timezone + `isExplicitlySet:false`; set → stored value + `true`
|
||||
(`admin.test.ts:631-663`).
|
||||
|
||||
- **IN-03 — per-drain-cycle timezone memoization
|
||||
(`apps/api/src/broker/outboxWorker.ts:385-395, 774`).** Correct. `makeTimezoneResolver` lazily
|
||||
caches the `getHouseholdTimezone(db)` promise so multiple all-day rows in one drain cycle share a
|
||||
single app_config read; cycles with no all-day work never touch the DB. The resolver is created
|
||||
per-cycle and discarded at cycle end, so a transient DB failure caching for one cycle is retried
|
||||
fresh next cycle, and a rejected resolve surfaces through the existing per-row catch as correct
|
||||
pending/transient behavior. No double-read regression. Both create (`:634`) and update (`:528`)
|
||||
all-day branches consume the shared resolver.
|
||||
|
||||
### Other checks (no regressions)
|
||||
|
||||
- **Access control.** `adminRouter.use('*', requireAdmin)` remains the first router statement; all
|
||||
three timezone routes (GET/PUT/POST-seed) sit behind it. 403 coverage exists for GET, PUT, and
|
||||
seed (`admin.test.ts:603-625, 711-720`).
|
||||
- **IANA validation.** Both PUT and seed share `timezoneSchema` with the try/catch-based
|
||||
`isValidIanaTimezone` (not `Intl.supportedValuesOf`, so `UTC` is accepted — Pitfall 2). Invalid
|
||||
input returns 400 and writes nothing (`admin.test.ts:684-701`).
|
||||
- **Broker async correctness.** `getHouseholdTimezone` is awaited before the all-day loop in
|
||||
`reminderScheduler.ts:250`; the outbox resolver is awaited inside each all-day branch. No
|
||||
un-awaited promises or new timer/handle leaks.
|
||||
- **D-07 boundary guard.** No changes to `eventDateTime.ts` / `hydrateEvents.ts`; the browser-local
|
||||
write/display path is untouched. AdminPage uses `Intl…resolvedOptions().timeZone` only for the
|
||||
"Use detected" affordance and never auto-writes (D-03 respected).
|
||||
|
||||
All reviewed files meet quality standards. No actionable issues remain.

## Threat Verification
|
||||
|
||||
| Threat ID | Category | Disposition | Status | Evidence |
|
||||
|-----------|----------|-------------|--------|----------|
|
||||
| T-18-01 | Tampering | mitigate | CLOSED | `householdTimezone.ts:25-35` reads only; never returns an unvalidated forwarded write. `resolveHouseholdTimezone` (`:49-61`) guarantees non-empty fallback (trim guard). All writes go through Plan 02 IANA-validated path. |
|
||||
| T-18-02 | DoS | accept | CLOSED | Accepted risk logged below. Single PK lookup per scheduler tick (`reminderScheduler.ts:250`). |
|
||||
| T-18-03 | Elevation of Privilege | mitigate | CLOSED | `admin.ts:42` `adminRouter.use('*', requireAdmin)` is the FIRST router statement, before all routes. GET (`:200`), PUT (`:224`), POST seed (`:251`) all appended after it → inherit the guard. 403 tests exist (`admin.test.ts:603-625, 711-720`). |
|
||||
| T-18-04 | Tampering | mitigate | CLOSED | `admin.ts:56-62` `timezoneSchema` uses `.refine(isValidIanaTimezone)`; PUT (`:224`) and seed (`:251`) both bind it via `zValidator('json', timezoneSchema)`. `isValidIanaTimezone` (`householdTimezone.ts:70-77`) is eval-free try/catch on `Intl.DateTimeFormat`. Invalid → 400 before any DB write. |
|
||||
| T-18-05 | Tampering | mitigate | CLOSED | Seed (`admin.ts:262-266`) uses `INSERT IGNORE`; an existing row is silently ignored (value preserved, D-03 no-overwrite). `seeded` derived from `affectedRows === 1`. Cannot overwrite an existing value. |
|
||||
| T-18-06 | Information Disclosure | accept | CLOSED | Accepted risk logged below. Grep confirms no `console.log` of request bodies in `admin.ts` (only a T-10-10 comment reference). Timezone is non-sensitive. |
|
||||
| T-18-07 | Injection | mitigate | CLOSED | PUT upsert (`admin.ts:227-230`) uses Drizzle `.insert().onDuplicateKeyUpdate` — parameterized, key is hard-coded literal `'household_timezone'`. Seed (`:262-263`) uses a `sql` template where `INSERT IGNORE` is a literal keyword, column identifiers via `sql.identifier`, and `${timezone}` is a bound parameter (not string-concatenated) and IANA-validated upstream. |
|
||||
| T-18-08 | Tampering | mitigate | CLOSED | Broker sites consume `getHouseholdTimezone(db)` only (`reminderScheduler.ts:250`, `outboxWorker.ts:391`). `resolveHouseholdTimezone` (`householdTimezone.ts:49-61`) trims stored value and `process.env.TZ`; empty/blank falls through to a valid Intl zone — fallback can never return `''`/invalid. |
|
||||
| T-18-09 | Tampering (regression) | mitigate | CLOSED | `git diff --name-only origin/main..HEAD` excludes `eventDateTime.ts` and `hydrateEvents.ts` (D-07 boundary intact). No timed-write/display path touched. |
|
||||
| T-18-10 | DoS | accept | CLOSED | Accepted risk logged below. Per-drain-cycle memoization (`outboxWorker.ts:385-395`, created `:774`) shares one app_config read across both all-day branches (`:527`, `:634`). |
|
||||
| T-18-11 | Elevation of Privilege | accept | CLOSED | Accepted risk logged below. Client gate is UX-only; server `requireAdmin` (`admin.ts:42`) is the real control. Client (`client.ts:498`) documents server enforcement. |
|
||||
| T-18-12 | Tampering | mitigate | CLOSED | Client `setAdminTimezone` (`client.ts:501-511`) sends raw input to server; server `timezoneSchema.refine` (`admin.ts:56-62`) is authoritative (400 on invalid). Free-text input (`AdminPage.tsx:387-406`) is not the security boundary. |
|
||||
| T-18-13 | Information Disclosure | mitigate | CLOSED | Timezone rendered as plain-text JSX (`AdminPage.tsx:431` `Use detected: {detectedTz}`) and as controlled input `value={effectiveTimezoneInput}` (`:390`). Grep confirms NO `dangerouslySetInnerHTML` in AdminPage.tsx. |
|
||||
| T-18-SC (×4, plans 01-04) | Supply chain | mitigate | CLOSED | `git diff origin/main..HEAD` against all `package.json` / `pnpm-lock.yaml` returns EMPTY — zero new dependencies. PWA picker uses built-in `Intl`. |
|
||||
|
||||
## Accepted Risks Log
|
||||
|
||||
- **T-18-02 (DoS — DB read per scheduler tick):** Single primary-key lookup on `app_config` per 60s scheduler interval. Negligible load; read-per-run chosen so timezone changes propagate within one tick without a worker restart. Accepted.
|
||||
- **T-18-06 (Information Disclosure — log/echo of submitted timezone):** Timezone identifiers are non-sensitive (not credentials or PII). No `noEchoHook` required; verified no body logging in handlers. Accepted.
|
||||
- **T-18-10 (DoS — extra DB read at 3 call sites):** Mitigated in practice by per-drain-cycle memoization; PK lookups on a 60s interval are negligible. Accepted.
|
||||
- **T-18-11 (Elevation of Privilege — client renders admin UI from isAdmin flag):** The client `isAdmin` gate is a UX convenience only. A forged request still hits server-side `requireAdmin` → 403 (T-18-03). The UI gate is not relied upon as a security control. Accepted.
|
||||
|
||||
## Unregistered Flags
|
||||
|
||||
None. All four plan SUMMARY `## Threat Flags` sections declare "No new threat surface beyond the plan's threat model." No new endpoints, auth paths, file-access patterns, or schema changes appeared during implementation that lack a mapped threat ID.
|
||||
|
||||
## Notes
|
||||
|
||||
- Post-review fixes (18-REVIEW-FIX.md: WR-01, WR-02, IN-01/02/03) were verified in code, not accepted on documentation alone:
|
||||
- WR-01 empty/blank TZ guard present at `householdTimezone.ts:50-58` (relevant to T-18-08).
|
||||
- WR-02 `INSERT IGNORE` + affectedRows-derived `seeded` present at `admin.ts:262-266` (relevant to T-18-05).
|
||||
- D-07 boundary independently confirmed via `git diff --name-only`.
|
||||
- Zero-dependency claim independently confirmed via empty manifest/lockfile diff.

## Sampling Rate
|
||||
|
||||
- **After every task commit:** Run `pnpm --filter @familysync/api test -- --run`
|
||||
- **After every plan wave:** Run `pnpm -r test -- --run`
|
||||
- **Before `/gsd-verify-work`:** Full suite must be green
|

|
||||
|
||||
## Wave 0 Requirements
|
||||
|
||||
- [ ] Backend unit-test stubs for the stored-tz accessor + fallback chain
|
||||
- [ ] Backend unit-test stubs for IANA validation
|
||||
- [ ] vitest already present — no framework install needed
|
||||
|
||||
*Existing all-day scheduler tests remain green unmodified (mock DB returns no app_config rows → D-06 fallback path).*
|
||||
|
||||

|
||||
|
||||
## Manual-Only Verifications
|
||||
|
||||
| Behavior | Requirement | Why Manual | Test Instructions |
|
||||
|----------|-------------|------------|-------------------|
|
||||
| Searchable IANA picker UX in /admin Settings | D-04 | Visual/interaction quality | Drive with `playwright-cli`: open /admin Settings, search a zone, save, reload, confirm persisted |
|
||||
|
||||
*iOS-Safari standalone behavior is out of scope for this phase.*
|
||||
|
||||
---
|
||||
|
||||
## Validation Sign-Off
|
||||
|
||||
- [ ] All tasks have `<automated>` verify or Wave 0 dependencies
|
||||
- [ ] Sampling continuity: no 3 consecutive tasks without automated verify
|
||||
- [ ] Wave 0 covers all MISSING references
|
||||
- [ ] No watch-mode flags
|
||||
- [ ] Feedback latency < 60s
|
||||
- [ ] `nyquist_compliant: true` set in frontmatter

Confirmed: Timezone section renders, input pre-filled, first-run Save enabled (WR-01 fix), changing input enables Save, save persists across reload with the 'Using system default' note disappearing, and 'Use detected' pre-fills the browser zone."
|

note: "Surfaced and fixed a test-determinism gap: e2e global-setup did not clear app_config.household_timezone, leaking a prior run's value. Fixed in commit ddeb87c (clear the key in global-setup + align the stale Save-disabled assertion with the WR-01 first-run behaviour)."

|

# Phase 18: Auto Timezone Detection and Ability to Change Timezone — Verification Report
|
||||
|
||||
**Phase Goal:** Make the household timezone an explicit, stored, user-changeable setting — auto-detected from the browser at first run, changeable from the role-gated /admin Settings — and route the server-side all-day "9 AM local" reminder computation through it (replacing the implicit `process.env.TZ` fallback), without touching the already-correct browser-local display/timed-write path.
|
||||
|
||||
**Decision contract:** D-01 stored in app_config; D-02 auto-detect/seed from browser at first run; D-03 seed must NOT overwrite an explicit value; D-04 changeable from role-gated /admin; D-05 single shared accessor is the source of truth; D-06 fallback chain (stored ?? process.env.TZ ?? Intl resolved zone) when unset; D-07 do NOT touch the browser-local display/timed-write path.
|
||||
|
||||
**Verified:** 2026-06-14T23:05:00Z
|
||||
**Status:** passed (all automated checks pass; browser round-trip re-confirmed via Playwright e2e against the live stack)
|
||||
**Re-verification:** No — initial verification

## Goal Achievement
|

|
||||
### Observable Truths (Decision Contract)
|
||||
|
||||
| # | Decision | Truth | Status | Evidence |
|
||||
|---|----------|-------|--------|----------|
|
||||
| 1 | D-01 | Household timezone stored as `household_timezone` key in `app_config` | VERIFIED | `admin.ts:229` — `db.insert(appConfig).values({ key: 'household_timezone', value: timezone }).onDuplicateKeyUpdate(...)` |
|
||||
| 2 | D-02 | Browser-detected zone seeded at first run via POST /api/admin/config/timezone/seed | VERIFIED | `admin.ts:248-273` — seed endpoint; `AdminPage.tsx:108` — `detectedTz = Intl.DateTimeFormat().resolvedOptions().timeZone`; seed endpoint called from PWA |
|
||||
| 3 | D-03 | Seed does NOT overwrite an explicit value | VERIFIED | `admin.ts:257-271` — SELECT-before-INSERT with `onDuplicateKeyUpdate({ set: { value: sql\`value\` } })` (WR-02 fix). Tests at `admin.test.ts:753-806` confirm no-overwrite and idempotency under race. |
|
||||
| 4 | D-04 | Timezone changeable from role-gated /admin only | VERIFIED | `admin.ts:42` — `adminRouter.use('*', requireAdmin)` is first statement; all three timezone routes registered after line 42 inherit the guard. Tests at `admin.test.ts:603-625` assert 403 for non-admin on GET and PUT. POST seed 403 test at line 711. |
|
||||
| 5 | D-05 | Single shared accessor `getHouseholdTimezone(db)` is the only TZ read site for brokers | VERIFIED | `reminderScheduler.ts:51,250` — import + `await getHouseholdTimezone(db)`. `outboxWorker.ts:46,504,612` — import + two call sites. No bare `process.env.TZ ?? Intl` expression remains at any call site (only in comments). No stragglers confirmed by grep returning zero non-comment hits. |
|
||||
| 6 | D-06 | Fallback chain: stored ?? process.env.TZ ?? Intl resolved zone | VERIFIED | `householdTimezone.ts:34-38` — `row?.value ?? process.env.TZ ?? Intl.DateTimeFormat().resolvedOptions().timeZone`. 11 unit tests in `householdTimezone.test.ts` cover all four branches (stored / TZ env / Intl / null-value fall-through). |
|
||||
| 7 | D-07 | `eventDateTime.ts` and `hydrateEvents.ts` NOT modified | VERIFIED | `git diff --name-only origin/main..HEAD` does not list either file. Output confirmed: "CONFIRMED: Neither file appears in branch diff". |
|
||||
|
||||
**Score:** 7/7 truths verified (automated)

### Required Artifacts
|
||||
|
||||
| Artifact | Expected | Status | Details |
|
||||
|----------|----------|--------|---------|
|
||||
| `apps/api/src/lib/householdTimezone.ts` | Shared TZ accessor + IANA validator (D-05, D-06) | VERIFIED | Exists, 55 lines, exports `getHouseholdTimezone` and `isValidIanaTimezone`. Verbatim D-06 fallback chain. No `Intl.supportedValuesOf` (avoids UTC-omission pitfall). |
|
||||
| `apps/api/tests/lib/householdTimezone.test.ts` | Unit tests for accessor fallback chain + validator | VERIFIED | Exists. 11 tests. Covers stored row, no-row + TZ env, no-row + no-TZ, null-value fall-through, valid zones (incl. 'UTC'), and invalid zones. |
|
||||
| `apps/api/src/routes/admin.ts` | GET + PUT + seed timezone endpoints under requireAdmin | VERIFIED | Exists. `timezoneSchema` with `isValidIanaTimezone` refine. GET at line 200, PUT at 224, seed at 248. All after line-42 `requireAdmin.use('*', ...)`. WR-02 fix applied (onDuplicateKeyUpdate in seed). |
|
||||
| `apps/api/tests/routes/admin.test.ts` | Integration tests: 403 non-admin, IANA 400/200, round-trip, seed no-overwrite | VERIFIED | Exists. 8 original timezone cases + 3 WR-02 cases added post-review (403 on seed, seeded:true on first, idempotent second). |
|
||||
| `apps/api/src/broker/reminderScheduler.ts` | All-day TZ rewired to getHouseholdTimezone (D-05) | VERIFIED | Line 51: import. Line 250: `const serverTz = await getHouseholdTimezone(db)`. Line 249 comment references D-06. |
|
||||
| `apps/api/src/broker/outboxWorker.ts` | Both all-day TZ sites rewired to getHouseholdTimezone (D-05) | VERIFIED | Line 46: import. Line 504: CREATE branch `const tz = await getHouseholdTimezone(db)`. Line 612: UPDATE branch same. Both in comment references D-06. |
|
||||
| `apps/pwa/src/api/client.ts` | `fetchAdminTimezone()` + `setAdminTimezone()` + `AdminTimezoneResponse` | VERIFIED | Lines 476-511. Interface defined at 476. GET wrapper at 485 with `credentials: 'include', redirect: 'manual', handleAuthResponse`. PUT wrapper at 501 with Content-Type header and body. |
|
||||
| `apps/pwa/src/routes/AdminPage.tsx` | Timezone section with searchable IANA picker, save, detected-zone affordance | VERIFIED | `<section aria-label="Timezone">` at line 342. `timezoneQuery` at line 93 with 60s staleTime. `timezoneMutation` at line 100. `detectedTz` at line 108. WR-01 fix at lines 114-128 (`isExplicit && ...` guard). "Use detected" affordance at line 415. "Using system default" notice at line 372. |
|
||||
| `apps/pwa/src/routes/AdminPage.timezone.test.ts` | Unit tests for WR-01 save-enabled logic | VERIFIED | Exists. Tests at line 44 and 57 cover first-run (isExplicitlySet: false) save-enabled case. |
|
||||
| `apps/pwa/e2e/timezone-verify.spec.ts` | Playwright e2e for browser round-trip | VERIFIED (exists) | 6 test cases: section visible, combobox pre-filled, save disabled when unchanged, changing enables save, persist across reload, "Use detected" affordance. Ran green at execution time against live stack. Cannot re-run without live Docker stack. |

### Anti-Patterns Found
|
||||
|
||||
| File | Line | Pattern | Severity | Impact |
|
||||
|------|------|---------|----------|--------|
|
||||
| `outboxWorker.ts` | 787 | "not yet done" in log message | Info | Existing code; pre-dates this phase; contextual log text in business-logic comment, not a debt marker |
|
||||
| `outboxWorker.ts` | 827 | "not yet applied" in comment | Info | Same as above; pre-existing natural-language description |
|
||||
| `AdminPage.tsx` | 392 | `placeholder="e.g. America/Chicago"` | Info | Input placeholder text; not a stub implementation indicator |
|
||||
|
||||
No TBD / FIXME / XXX / unreferenced debt markers found in any of the six Phase 18 production files.

### Human Verification Required
|
||||
|
||||
#### 1. Admin Timezone Picker Browser Round-Trip
|
||||
|
||||
**Test:** With the dev stack running and DEV_AUTH_BYPASS user flagged as admin, navigate to `/admin`. Observe the Timezone section.
|
||||
|
||||
Steps:
|
||||
1. Confirm "Timezone" section is visible, showing current household timezone (or "Using system default" note).
|
||||
2. Type a city (e.g. "Chicago"), pick "America/Chicago" from the datalist, click Save.
|
||||
3. Reload `/admin` and confirm the section shows "America/Chicago" with no "system default" note.
|
||||
4. Confirm the "Use detected: `<zone>`" affordance appears when the input does not match the browser zone.
|
||||
5. Click "Use detected: `<zone>`" — confirm it fills the input.
|
||||
6. Confirm save button is disabled when the input matches the stored value and the value is already explicit.
|
||||
7. Confirm save button is ENABLED when `isExplicitlySet: false` even if the input matches the displayed default (WR-01 fix).
|
||||
|
||||
**Expected:** Value persists across reload; no console errors; save button disables correctly; first-run scenario allows saving the displayed default to make it explicit.
|
||||
|
||||
**Why human:** Playwright e2e spec (`timezone-verify.spec.ts`, 6 tests) was run against the live stack at execution time and passed. Re-running requires the full Docker stack with DEV_AUTH_BYPASS=true and an admin-flagged user, which cannot be driven from this verification process. iOS/Safari behavior is also out of scope for playwright-cli.

### Gaps Summary
|
||||
|
||||
No automated gaps found. All seven decision-contract truths are VERIFIED against the codebase.
|
||||
|
||||
**Post-review fixes applied and confirmed:**
|
||||
- WR-01 (`173e06e`): `timezoneSaveDisabled` now allows saving when `isExplicitlySet: false` even if the input matches the displayed default. Unit tests at `AdminPage.timezone.test.ts:44,57` cover this.
|
||||
- WR-02 (`bda31a3`): Seed endpoint uses `onDuplicateKeyUpdate({ set: { value: sql\`value\` } })` to prevent duplicate-key 500 under concurrent race. Four tests in `admin.test.ts:711-806` cover the 403, seeded:true, no-overwrite, and idempotent-race cases.
|
||||
|
||||
**Accepted review item:**
|
||||
- WR-03 (GET handler issues a second DB round-trip on unset path via `getHouseholdTimezone(db)` after already reading the row): accepted in 18-REVIEW.md as a minor inefficiency, not a correctness issue. No impact on goal achievement.
|
||||
|
||||
The only pending item is the human browser verification of the admin timezone picker UI (Task 3 of Plan 18-04), which was executed and passed at phase execution time but cannot be re-run without the live stack.
