 - [x] Web Push notifications for event reminders and list changes — **Validated in Phase 5 (web-push-notifications)**: VAPID push for reminders, event-change, and coalesced list alerts; on-device UAT 1/2/5 PASS (iOS reminder delivery, iOS push, coalescing). Android event-change on-device confirmation + iOS standalone spinner remain device-only spot-checks at go-live.
 - [x] Faster write-back so edits reach Fastmail in ~1–2s instead of ~15s (CAL-15) — **Validated in Phase 9 (faster-write-back)**: event-driven outbox drain via a zero-dependency in-process EventEmitter (`outboxTrigger.ts`); a committed enqueue publishes a fire-and-forget `signalOutboxDrain()` that funnels through the existing `isDraining`-guarded drain with a `drainRequested` trailing-re-drain, preserving optimistic-202, create-before-delete on moves, exactly-once per uid, and the 15s `setInterval` fallback. 5/5 success criteria verified; trigger-wiring tests assert SC-1/D-05/D-07.

Shipping with a single provider is fine, but the broker, sync, and event-expansion layers should be structured so additional providers (e.g. other CalDAV hosts, Google Calendar, generic ICS feeds) can be added without rework.

 # Phase 10 Plan 03: Admin API Surface + Shared Credential Helper Summary
 **One-liner:** Single shared `validateEncryptAndStoreCredential` helper (CalDAV PROPFIND + AES-256-GCM encrypt + upsert + fire-and-forget sync) consumed by `adminRouter` (requireAdmin-first, ADMIN-01/02/03) and `/api/me/credential` self-service (D-07, member-scoped).
 ## Tasks Completed
 | Task | Name | Commits | Files |
 |------|------|---------|-------|
 | 1 | Promote broker resync helpers to exports | ac36e10 | apps/api/src/broker/outboxWorker.ts |
 | 2 RED | Write failing tests for admin surface | 037a7ed | apps/api/tests/routes/admin.test.ts |
 | 2+3 GREEN | credentialSync helper + adminRouter + /api/me/credential | d2f6d5d | credentialSync.ts, admin.ts, index.ts, me.ts |
 ## What Was Built
 ### Task 1: Promote broker resync helpers to exports
 Added `export` keyword to `loadClientForUser` (line 271) and `triggerTargetedResync` (line 302) in `outboxWorker.ts`. Function bodies are byte-for-byte unchanged — only the visibility changed. The outbox drain cycle and `setInterval` scheduling are untouched. No `node-cron` reintroduced.
 ### Task 2+3: RED → GREEN
 **RED:** `apps/api/tests/routes/admin.test.ts` created with 17 test cases covering:
 - T-10-08 (Pitfall 9): GET /api/admin/members, POST /credentials, GET /calendars, PUT /calendars/:id/shared all return 403 for non-admin
 - T-10-09 (Pitfall 7): POST /api/admin/credentials with PROPFIND auth failure, createFastmailClient throw, network error → all return 400 `{ error: 'Invalid request' }` with the submitted password string absent from the response
 - T-10-09: zValidator schema failure → same generic 400, no Zod .received echo
 - T-10-11: valid credential → 200, stored AES-256-GCM encrypted (not plaintext)
 - ADMIN-02: PUT /api/admin/calendars/:id/shared → exactly one calendar has is_shared=1
 - T-10-12 (Pitfall 6): POST /api/me/credential with body userId for another user → credential written only to session user
 - D-07: non-admin member can POST /api/me/credential (no requireAdmin required)
 All 17 tests confirmed RED (404/assertion failures) before implementation.
 **GREEN:**
 `apps/api/src/broker/credentialSync.ts` — shared helper:
 1. `createFastmailClient(email, appPassword)` + `await client.fetchCalendars()` in ONE try/catch → any failure throws `CredentialValidationError` (typed; no password detail in the exception)
 2. `encryptPassword(appPassword)` → AES-256-GCM JSON ciphertext
 3. `db.insert(memberCredentials).onDuplicateKeyUpdate(...)` → upsert (UNIQUE(user_id) from 10-01)
 4. Fire-and-forget: `loadClientForUser(userId)` → `syncCalendar(...)` per davCal
 `apps/api/src/routes/admin.ts`:
 - `export const adminRouter = new Hono()` immediately followed by `adminRouter.use('*', requireAdmin)` (Pitfall 9)
 - Side-effect import of `../auth/devBypass.js` for ContextVariableMap
 - `GET /members`: users LEFT JOIN member_credentials → `{ members: [{ id, displayName, color, hasCredential }] }`
 - `POST /credentials`: `zValidator('json', credentialSchema, noEchoHook)` → `validateEncryptAndStoreCredential(body.userId, ...)` → 200 or 400/503
 - `GET /calendars`: `{ calendars: [{ id, displayName, isShared }] }`
 - `PUT /calendars/:id/shared`: clear all `is_shared=true`, set target → 200
 `apps/api/src/index.ts`: `app.route('/api/admin', adminRouter)` added after existing route block.
 `apps/api/src/routes/me.ts`:
 - `POST /credential` added with `meCredentialSchema` (no userId field — Pitfall 6)
 - `meNoEchoHook` identical pattern to admin noEchoHook
 - Handler: `resolveUserId(c)` from session → `validateEncryptAndStoreCredential(currentUserId, ...)` — body userId ignored
 ## Deviations from Plan
 None — plan executed exactly as written.
 ## Known Stubs
 None. All routes are fully implemented with real DB and real CalDAV integration (mocked in tests). No placeholder data.
 ## Threat Flags
 No new threat surface beyond the plan's threat model. All T-10-08 through T-10-13 mitigations implemented:
 - T-10-08: adminRouter.use('*', requireAdmin) guard-first
 - T-10-09: noEchoHook + CredentialValidationError → generic 400
 - T-10-10: no console.log of body/password in admin.ts, me.ts, or credentialSync.ts
 - T-10-11: encryptPassword applied before DB write; tests assert encrypted != plaintext
 - T-10-12: /api/me/credential uses currentUserId from session exclusively; test proves other user's row is untouched
 ## Self-Check: PASSED
 - `grep -n "adminRouter.use" apps/api/src/routes/admin.ts` shows `.use('*', requireAdmin)` at line 41 (first executable statement after router creation on line 37): PASS
 - `grep "app.route('/api/admin'" apps/api/src/index.ts` confirms mount: PASS
 - `grep "validateEncryptAndStoreCredential" apps/api/src/routes/admin.ts` shows import + call: PASS

 # Phase 10 Plan 04: React PWA Admin Surfaces Summary
 **One-liner:** React PWA admin surfaces — isAdmin/needsProviderSetup client types, five typed admin fetchers, gated `/admin` route (AdminPage + CredentialSheet + SetupBanner), conditional ShieldCheck nav entries, and 15 e2e assertions across 3 device profiles all green.
 ## Tasks Completed
 | Task | Name | Commits | Files |
 |------|------|---------|-------|
 | 1 | Extend client.ts — MeUser fields + admin/self-service fetchers | bfe1eff | apps/pwa/src/api/client.ts |
 | 2 | CredentialSheet + SetupBanner components | 2c2c71e | CredentialSheet.tsx, SetupBanner.tsx |
 | 3 | /admin route + AdminPage + conditional nav entries + e2e spec | 7808426 | AdminPage.tsx, App.tsx, AppNav.tsx, BottomTabBar.tsx, admin.spec.ts |
 | fix | Prettier format + type assertion cleanup | 79fe3e0 | 8 files (PWA + API) |
 ## What Was Built
 ### Task 1: Extend client.ts
 `apps/pwa/src/api/client.ts` extended with:
 - `MeUser.isAdmin: boolean` — UX gating flag (D-03; server enforces 403 on /api/admin/*)
 - `MeUser.needsProviderSetup: boolean` — drives SetupBanner display
 - `AdminMember`, `SaveCredentialPayload`, `AdminCalendar`, `SaveMyCredentialPayload` types matching Plan-03 shapes
 - `fetchAdminMembers()` → GET /api/admin/members
 - `saveCredential(payload)` → POST /api/admin/credentials (includes userId — admin-scoped)
 - `fetchAdminCalendars()` → GET /api/admin/calendars
 - `setSharedCalendar(calendarId)` → PUT /api/admin/calendars/:id/shared
 - `saveMyCredential(payload)` → POST /api/me/credential (NO userId — member-scoped, T-10-12)
 All fetchers use `credentials:'include'`, `redirect:'manual'`, `handleAuthResponse`. Password never logged or stored beyond in-flight request body (T-10-15).
 ### Task 2: CredentialSheet + SetupBanner
 **CredentialSheet** (`apps/pwa/src/components/CredentialSheet.tsx`):
 - Three modes: `admin-rotate`, `admin-add`, `self-service` — heading copy varies per mode
 - `role="dialog" aria-modal="true"` bottom sheet, zIndex 301 (backdrop 300), 12px 12px 0 0 borderRadius
 - `type="password" autoComplete="new-password"` — NEVER pre-filled (T-10-16)
 - Helper text with Fastmail link `target="_blank" rel="noopener noreferrer"` (UI-SPEC Surface 3)
 - Loader2 spinner + "Validating against CalDAV…" during mutation
 - CalDAV failure copy on error state
 - On success: `invalidateQueries(['admin','members'])` + `invalidateQueries(['me'])` → needsProviderSetup refreshes
 - Escape closes; focus returns to trigger element (a11y)
 **SetupBanner** (`apps/pwa/src/components/SetupBanner.tsx`):
 - Renders only when `meQuery.data?.user.needsProviderSetup === true`
 - `role="status" aria-live="polite"` (screen reader announcement on load)
 - KeyRound icon + "Set up your calendar" + body copy + "Set up now" CTA
 - NO dismiss button — the ONLY exit is a successful credential save that flips needsProviderSetup → false
 - Opens CredentialSheet in self-service mode
 ### Task 3: /admin route + AdminPage + nav entries + e2e
 **AdminPage** (`apps/pwa/src/routes/AdminPage.tsx`):
 - "Admin Settings" h1 (18px/600), maxWidth 640px centered desktop, var(--space-12) padding
 - MEMBERS section: avatar swatch + member name + "Credential set" / "No credential" badge + "Rotate"/"Add credential" button
 - SHARED CALENDAR section: radio group with "Currently shared" label, two-tap Save (disabled until selection differs), empty state copy
 - Opens CredentialSheet for each member on row button click
 **App.tsx** additions:
 - `/admin` Route gated: `meQuery.isLoading → <div aria-hidden>` (no flash), `isAdmin → <AdminPage />`, else `<Navigate to="/calendar" replace />`
 - `<SetupBanner />` mounted above Routes in the content area
 - `isAdmin` prop forwarded to AppNav and BottomTabBar
 **AppNav.tsx** + **BottomTabBar.tsx**:
 - ShieldCheck (size 18/22) Admin entry with `aria-label="Admin settings"` rendered ONLY when `isAdmin === true`
 - Conditional import of ShieldCheck from lucide-react
 **admin.spec.ts** (`apps/pwa/e2e/admin.spec.ts`):
 - Admin user (seeded `is_admin=true` by global-setup): nav entry visible, /admin renders heading + Members section
 - Non-admin (route-mocked `isAdmin:false`): no nav entry, /admin redirects to /calendar via `waitForURL`
 - 15 assertions across iphone/pixel/desktop profiles — all pass
 ## Playwright-CLI Supplementary Observations
 Admin user (is_admin=true, seeded via mysql2 for playwright-cli check), navigated to `http://localhost:5173/admin`:
 **Snapshot confirms:**
 - "Admin settings" link in desktop nav sidebar visible with ShieldCheck icon
 - SetupBanner renders: role=status, "Set up your calendar" heading, "Set up now" CTA (needsProviderSetup=true for dev-bypass user)
 - "Admin Settings" h1 visible
 - MEMBERS section: 3 members (Dev User, luc@bergermail.ca, amelia@bergermail.ca), each showing "No credential" + "Add credential" button
 - SHARED CALENDAR section: radiogroup with "FamilySync Currently shared" selected, Save button disabled (no change)
 - Clicking "Add credential" for Dev User opens `dialog "Add Credential"` with email+password fields, helper text with Fastmail link, Cancel + "Save Credential" (disabled until fields filled)
 **Non-admin redirect:** Verified via e2e spec (page.route mock) — 5/5 tests confirmed. playwright-cli route mock intercepted the wrong URL (`localhost:3000/api/me` instead of the Vite-proxied `/api/me`) so the non-admin visual was not observed in the browser session, but the e2e spec is the binding proof per the plan.
 ## Deviations from Plan
 ### Auto-fixed Issues
 **1. [Rule 1 - Bug] meQuery loading gate rendered null instead of redirect-safe element**
 - **Found during:** Task 3 e2e run (test: "non-admin navigating to /admin is redirected to /calendar")
 - **Issue:** `meQuery.isLoading ? null` renders nothing as the Route element, but React Router does not trigger a Navigate when the element is null — the URL stays at /admin and no redirect fires during the loading window
 - **Fix:** Changed to `meQuery.isLoading ? <div aria-hidden />` so the route is occupied during loading, then the Navigate fires once meQuery resolves with isAdmin:false
 - **Files modified:** apps/pwa/src/App.tsx
 - **Commit:** 7808426
 **2. [Rule 1 - Bug] e2e redirect test raced ahead of Navigate render**
 - **Found during:** Task 3 e2e run (same test as above)
 - **Issue:** Test checked URL immediately after `page.goto('/admin')`, before the meQuery resolved and Navigate rendered
 - **Fix:** Added `await page.waitForURL(/\/calendar/, { timeout: 10_000 })` to wait for the actual redirect before asserting pathname
 - **Files modified:** apps/pwa/e2e/admin.spec.ts
 - **Commit:** 7808426
 **3. [Rule 2 - Formatting] Pre-existing prettier violations in Plan 02/03 API files**
 - **Found during:** CI gate (format:check)
 - **Issue:** apps/api/src/routes/me.ts, tests/auth/user.test.ts, tests/lib/requireAdmin.test.ts, tests/routes/me.test.ts had unformatted lines from Plan 02/03 commits (the workspace format:check was already failing before this plan's changes)
 - **Fix:** Ran prettier --write on those files; 270 API tests still pass
 - **Files modified:** 4 API files
 - **Commit:** 79fe3e0
 **4. [Rule 1 - Bug] Unnecessary type assertions flagged by ESLint**
 - **Found during:** CI gate (lint)
 - **Issue:** Two `as React.RefObject<HTMLElement | null>` casts in SetupBanner.tsx and AdminPage.tsx — ESLint @typescript-eslint/no-unnecessary-type-assertion flagged them as redundant
 - **Fix:** Removed both casts; TS already accepted the RefObject types without casting
 - **Files modified:** apps/pwa/src/components/SetupBanner.tsx, apps/pwa/src/routes/AdminPage.tsx
 - **Commit:** 79fe3e0
 ## Known Stubs
 None. All admin surfaces are fully wired to the live API endpoints. CredentialSheet performs real CalDAV validation (via the server's validateEncryptAndStoreCredential). The SetupBanner uses the real ['me'] query. AdminPage fetches live member + calendar data.
 ## Threat Flags
 No new threat surface beyond the plan's threat model:
 - T-10-14: /admin client redirect is UX-only; server 403 (requireAdmin) is the real boundary — confirmed
 - T-10-15: password field never pre-filled, never in state beyond in-flight mutation body — confirmed
 - T-10-16: autoComplete="new-password" on password input — confirmed
 - T-10-SC: No new packages installed (lucide-react ShieldCheck/KeyRound already in 1.17.0)

 # Phase 10: Code Review Report
 **Reviewed:** 2026-06-13
 **Depth:** standard
 **Files Reviewed:** 21
 **Status:** issues_found
 ## Summary
 Phase 10 adds admin-role primitives (`users.is_admin`, first-login-wins bootstrap), a DB-backed `requireAdmin` guard, an admin/self-service credential surface, and an exclusive shared-calendar designator. The core security contracts hold up well: `requireAdmin` reads `is_admin` from the DB (not the context user), all `/api/admin/*` routes are gated by `adminRouter.use('*', requireAdmin)` as the first statement, the no-echo hook is applied to both credential routes, and `/api/me/credential` resolves `currentUserId` from the session and ignores any body `userId`. The migration is additive (no DROP/TRUNCATE).
 The defects found are concentrated in two areas: (1) the first-login-wins admin bootstrap and shared-calendar designation are non-atomic multi-statement operations with no transaction or row-count guard, and (2) several routes/inputs lack existence/identity validation that lets the system silently enter a wrong state. The single BLOCKER is the shared-calendar PUT, which can leave the household with **zero** shared calendars while returning `{ ok: true }`.
 **Scope limitation:** Two in-scope files could not be read — `apps/api/src/broker/credentialSync.ts` (the central validate/encrypt/store helper) and `apps/pwa/src/components/CredentialSheet.tsx` (the credential input form) — both are in directories denied by the sandbox. Their behavior was reviewed indirectly via call sites (`admin.ts`, `me.ts`) and the integration tests (`admin.test.ts`), which confirm encryption-at-rest and no-echo on the wire. The crypto implementation itself (IV reuse, auth-tag handling, key derivation) and the sheet's client-side handling of the password (e.g. whether it is held in state longer than the request, autocomplete attributes) were **not** directly inspected and should be re-reviewed separately.
 ## Critical Issues
 ### CR-01: Shared-calendar PUT can clear the only shared calendar and report success
 **File:** `apps/api/src/routes/admin.ts:150-163`
 **Issue:** `PUT /api/admin/calendars/:id/shared` runs two independent UPDATEs:
 ```js
 await db.update(calendars).set({ isShared: false }).where(eq(calendars.isShared, true)); // clear
 await db.update(calendars).set({ isShared: true }).where(eq(calendars.id, targetId));    // set
 ```
 `targetId` is only checked for `isNaN`, never for existence. If the id does not match any row (deleted calendar, stale client cache, hand-crafted request, off-by-one from a re-sync that re-keyed calendar ids), step 1 still clears the previously-shared calendar and step 2 updates **0 rows**. The handler then returns `{ ok: true }`. Result: the household silently ends up with **no** shared calendar — the shared family lane disappears for every member, and the UI's `Currently shared` indicator shows nothing, with no error surfaced. This is a data-state-loss / correctness defect in the core ADMIN-02 flow. The two statements are also non-transactional, so a crash between them leaves zero shared calendars even for a valid id.
 **Fix:** Validate the target exists and make the swap atomic. Check the affected-row count of the set, and roll back / 404 if it is zero:
 ```js
 adminRouter.put('/calendars/:id/shared', async (c) => {
  const targetId = parseInt(c.req.param('id'), 10);
  if (Number.isNaN(targetId)) {
    return c.json({ error: 'Invalid calendar id' }, 400);
  }
  // Confirm the target exists BEFORE clearing the current selection.
  const [target] = await db
    .select({ id: calendars.id })
    .from(calendars)
    .where(eq(calendars.id, targetId))
    .limit(1);
  if (!target) {
    return c.json({ error: 'Calendar not found' }, 404);
  }
  // Wrap both writes in a transaction so a crash cannot strand zero shared calendars.
  await db.transaction(async (tx) => {
    await tx.update(calendars).set({ isShared: false }).where(eq(calendars.isShared, true));
    await tx.update(calendars).set({ isShared: true }).where(eq(calendars.id, targetId));
  });
  return c.json({ ok: true }, 200);
 });
 ```
 ## Warnings
 ### WR-01: First-login-wins admin bootstrap is a non-atomic check-then-insert (TOCTOU)
 **File:** `apps/api/src/auth/user.ts:118-136`
 **Issue:** The zero-admin `COUNT(*)` and the subsequent `INSERT ... isAdmin: shouldBeAdmin` are separate statements with no transaction or locking. Two genuinely-concurrent first logins (two different OIDC identities hitting `/api/me` at the same time on a cold DB) can both read `count === 0` and both insert with `isAdmin: true`, producing two admins instead of one. The comment claims first-login-wins, but the implementation does not enforce a single winner. For a two-person household this is low-probability, but it is a privilege-escalation-adjacent correctness gap in exactly the bootstrap the phase is meant to harden, and Phase 12 is documented to build on this hook.
 **Fix:** Perform the count and insert inside a single transaction with a row lock (e.g. `SELECT ... FOR UPDATE` on the users table or an advisory lock), or gate admin assignment on a `UNIQUE` partial constraint / `app_config` flag set atomically. Minimum viable fix: wrap steps 2-5 in `db.transaction` and re-read the admin count inside it with `FOR UPDATE`.
 ### WR-02: `resolveUserId` / `/api/me` will upsert a user with empty-string iss or sub
 **File:** `apps/api/src/routes/me.ts:81-85` and `:115-123`
 **Issue:** Both the `resolveUserId` helper and the main `/api/me` handler coalesce missing claims to empty strings: `const sub = auth.sub ?? ''` and `const iss = (auth.iss as string | undefined) ?? ''`. If a malformed/partial token ever reaches here with a missing `sub` (the OIDC middleware is mocked as a passthrough in tests, and real-world token edge cases exist), `upsertUser('', '', ...)` creates a bogus identity row keyed on `('', '')`. Because identity is the composite `(oidc_iss, oidc_sub)` unique key, the first such request claims that row and — if it is the first user — becomes the bootstrap **admin**. Subsequent empty-claim requests from any user would then resolve to that same row, conflating distinct sessions into one admin identity.
 **Fix:** Reject empty identity instead of inventing one:
 ```js
 const iss = typeof auth.iss === 'string' ? auth.iss : '';
 const sub = typeof auth.sub === 'string' ? auth.sub : '';
 if (!iss || !sub) {
  return c.json({ error: 'Unauthorized' }, 401);
 }
 ```
 Apply the same guard in `resolveUserId` (return `null`).
 ### WR-03: New `UNIQUE(user_id)` on a populated `member_credentials` table will fail the migration if duplicates exist
 **File:** `apps/api/src/db/migrations/0001_famous_mad_thinker.sql:11`
 **Issue:** `ALTER TABLE member_credentials ADD CONSTRAINT uniq_member_credential_user UNIQUE(user_id)` is additive (good — no data destroyed), but if any user already has more than one credential row in a deployed environment, MariaDB rejects the `ALTER` with error 1062 and the entire migration fails partway. The earlier `ADD COLUMN` statements in the same file may have already committed (MariaDB DDL is non-transactional), leaving the schema in a half-applied state that is awkward to recover. Schema design intends one-credential-per-member, but nothing earlier in the project enforced it, so existing prod data may violate it.
 **Fix:** Before adding the constraint, de-duplicate. Either ship a pre-migration cleanup (`DELETE` keeping the newest row per `user_id`) or verify in the deploy runbook that no duplicates exist. At minimum, document the failure mode in the migration so an operator hitting 1062 knows to clean up and re-run, rather than assuming corruption.
 ### WR-04: `GET /api/admin/members` exposes every member's id/displayName/color to any admin — no per-row credential value, but unbounded result set
 **File:** `apps/api/src/routes/admin.ts:73-92`
 **Issue:** The query `leftJoin`s `member_credentials` and maps `hasCredential: row.credentialId !== null`. This is correct and does **not** leak the encrypted password (good). However: (a) there is no `limit`, so the endpoint returns the full users table — fine for two members, but the "N-member expansion intent" recorded in project memory means this should be paginated or at least bounded before it ships to a larger household; and (b) the `leftJoin` would emit duplicate member rows (and a misleading member count) if the new `UNIQUE(user_id)` constraint were ever absent or dropped — the correctness of `hasCredential` silently depends on that constraint holding. Defense-in-depth: either aggregate (`MAX(credentialId)` / `EXISTS`) or document the hard dependency.
 **Fix:** Use an existence subquery instead of a join so the result is one row per user regardless of credential cardinality:
 ```js
 const rows = await db.select({
  id: users.id, displayName: users.displayName, color: users.color,
  hasCredential: sql<boolean>`EXISTS (SELECT 1 FROM member_credentials mc WHERE mc.user_id = ${users.id})`,
 }).from(users);
 ```
 ### WR-05: `/api/admin/calendars` returns `displayName` typed as non-null, but the column is nullable
 **File:** `apps/api/src/routes/admin.ts:130-140`, contract `apps/pwa/src/api/client.ts:364-368`
 **Issue:** `calendars.displayName` is `varchar('display_name', { length: 256 })` — **nullable** (schema.ts:95). The admin endpoint selects it raw and the client type `AdminCalendar.displayName: string` (client.ts:366) declares it non-null. `CalendarRadioRow` renders `{calendar.displayName}` directly (AdminPage.tsx:492). A calendar synced without a `DISPLAYNAME` prop (possible from CalDAV) yields a radio row with an empty/blank label that the admin cannot distinguish from others, making the exclusive-select picker ambiguous. The type also lies, so downstream `.length`/string ops on it are unguarded.
 **Fix:** Type it as `string | null` in `AdminCalendar` and render a fallback (e.g. the calendar URL tail or "Untitled calendar") in `CalendarRadioRow`.
 ### WR-06: Admin nav/route gating depends on a client-mutable `isAdmin` with no server re-check on the data routes' shape
 **File:** `apps/pwa/src/App.tsx:75,141-152`, `apps/pwa/src/routes/AdminPage.tsx`
 **Issue:** This is correctly documented as "UX only" and the server enforces 403 on `/api/admin/*` — that boundary is sound. The warning is narrower: the `/admin` route element renders `meQuery.isLoading ? <div/> : isAdmin ? <AdminPage/> : <Navigate/>`. `retry: false` plus an error state (`meQuery.isError`, not `isLoading`) makes `isAdmin` fall to `false` and redirect — acceptable. But on a **stale** cached `['me']` (staleTime 5min) where the admin was demoted server-side, the PWA keeps showing the Admin surface and firing admin queries until the cache refreshes; those queries 403 and surface as "Could not load members." This is a confusing-but-safe degradation, worth noting because the AdminPage has no explicit handling that distinguishes a 403 (you are no longer admin) from a transient error.
 **Fix:** In `AdminPage`, treat a 403 from `fetchAdminMembers`/`fetchAdminCalendars` as an authority revocation — invalidate `['me']` and redirect to `/calendar` rather than rendering the generic error.
 ### WR-07: `triggerTargetedResync` client cache holds decrypted Fastmail credentials in a Map for the whole drain cycle
 **File:** `apps/api/src/broker/outboxWorker.ts:687-689, 302-313`
 **Issue:** IN-01's per-cycle `clientCache: Map<number, FastmailClient>` was added to decrypt each member's app password at most once per drain. The tradeoff: a decrypted-credential-bearing client object now lives for the duration of the entire drain loop (up to 10 rows plus bounded 10s re-syncs each), and the Map is captured by the closures passed to `syncCalendar`. The code comment frames this as a security improvement, but it also widens the lifetime of the decrypted secret in memory versus decrypt-per-row. Not a leak per se (the Map is local and GC'd at function return), but it is the opposite of the stated T-03-13 "narrow the window" goal and deserves an explicit note that the cache must never be hoisted to module scope.
 **Fix:** Acceptable as-is for the single-process two-user deployment, but add an assertion/comment that `clientCache` is function-local and consider clearing it (`clientCache.clear()`) in a `finally` so the references drop before the function's lexical scope is collected. Re-review once `credentialSync.ts`/`crypto.ts` are inspectable to confirm the `FastmailClient` does not retain the plaintext password as a field.
 ## Info
 ### IN-01: Two in-scope files were not reviewable (sandbox denial)
 **File:** `apps/api/src/broker/credentialSync.ts`, `apps/pwa/src/components/CredentialSheet.tsx`
 **Issue:** Both are in directories denied by the review sandbox and could not be read. `credentialSync.ts` is the single most security-relevant file in the phase (it owns encrypt + validate + store of the Fastmail app password). Its contract was inferred from call sites and the green integration tests (encryption-at-rest and no-echo verified on the wire), but the crypto internals were not audited.
 **Fix:** Re-run this review with read access to `apps/api/src/broker/` and `apps/pwa/src/components/`, or have a reviewer with access audit AES-GCM IV uniqueness, auth-tag verification on decrypt, key sourcing from `APP_PASSWORD_ENCRYPTION_KEY`, and the sheet's password-state lifetime / `autoComplete="off"`.
 ### IN-02: `noEchoHook` / `meNoEchoHook` are byte-identical duplicates
 **File:** `apps/api/src/routes/admin.ts:60-64`, `apps/api/src/routes/me.ts:164-168`
 **Issue:** The two no-echo Zod hooks are identical (`{ error: 'Invalid request' }` 400). Duplicating the security-critical no-echo contract in two files risks the two copies drifting (one gets "improved" to include details). The project convention is to duplicate auth helpers per-router, so this is allowed, but a shared `noEchoHook` constant would make the no-echo guarantee single-sourced.
 **Fix:** Optional — extract to a shared `lib/noEchoHook.ts` so the T-10-09 contract has one definition.
 ### IN-03: `resolveAdminAndSetupStatus` issues two sequential round-trips per `/api/me`
 **File:** `apps/api/src/routes/me.ts:50-67`
 **Issue:** Each `/api/me` does an `isAdmin` select then a `memberCredentials` existence select, serially. Functionally correct; minor. (Performance is out of v1 scope — noted only as a code-quality observation, not flagged as a perf defect.)
 **Fix:** Could be a single join, but not required.
 ### IN-04: `parseInt` without explicit radix appears once; the shared-cal route correctly passes radix 10
 **File:** `apps/api/src/routes/admin.ts:151`
 **Issue:** `parseInt(c.req.param('id'), 10)` correctly passes the radix — good. Noting for completeness that this is the only numeric parse in the admin surface and it is done correctly; no leading-zero/octal hazard.
 **Fix:** None.
 ### IN-05: AdminPage error copy collapses all mutation failures to "Something went wrong"
 **File:** `apps/pwa/src/routes/AdminPage.tsx:274-285`
 **Issue:** `sharedCalMutation.isError` renders a generic message. Combined with CR-01 (the server can return `{ ok: true }` even when it set nothing), the user has no signal that a save no-op'd. Once CR-01 is fixed to return 404, this generic toast will at least fire on the not-found path, but a specific "That calendar no longer exists — refresh" message would be clearer.
 **Fix:** Distinguish 404 from transient errors in the mutation's `onError`.

 # Phase 10: Admin Role & Settings Verification Report
 **Phase Goal:** DB foundation (users.is_admin / calendar_events.reminder_lead_minutes / app_config table) + role-gated admin UI to rotate member app passwords and designate the shared calendar.
 **Verified:** 2026-06-13T15:45:00Z
 **Status:** passed
 **Re-verification:** No — initial verification
 ## Goal Achievement
 ### Observable Truths
 | # | Truth | Status | Evidence |

 | 1 | Live dev MariaDB has users.is_admin, member_credentials.provider_type + UNIQUE(user_id), calendar_events.reminder_lead_minutes, and app_config table | VERIFIED | 271/271 api tests pass; migration file 0001_famous_mad_thinker.sql is additive-only (CREATE TABLE app_config, ALTER TABLE ... ADD COLUMN for all four items, ADD CONSTRAINT UNIQUE); orchestrator confirmed via live mysql2 SHOW COLUMNS/SHOW TABLES query |
 | 2 | Migration is additive-only (no DROP/TRUNCATE) | VERIFIED | `grep -iE "drop\|truncate" 0001_famous_mad_thinker.sql` returns 0 matches; migration content confirmed: only CREATE TABLE + ALTER TABLE ADD COLUMN + ADD CONSTRAINT |
 | 3 | requireAdmin is DB-backed (reads users.is_admin, not a context flag) and is the FIRST statement on adminRouter | VERIFIED | `requireAdmin.ts` lines 36-40: Drizzle select on `users.isAdmin` column; `admin.ts` line 41: `adminRouter.use('*', requireAdmin)` is the first statement after router creation; 271/271 tests confirm 403 for non-admin |

 ### Requirements Coverage
 | Requirement | Source Plan | Description | Status | Evidence |
 |-------------|-------------|-------------|--------|----------|
 | ADMIN-01 | 10-01, 10-02, 10-03, 10-04 | Admin can rotate member Fastmail app password (CalDAV-validated, encrypted, never echoed) | SATISFIED | admin.ts POST /credentials; validateEncryptAndStoreCredential; noEchoHook; AdminPage + CredentialSheet UI; passing tests |
 | ADMIN-02 | 10-01, 10-03, 10-04 | Admin can designate shared calendar from UI | SATISFIED | admin.ts PUT /calendars/:id/shared; CR-01 fix (transaction + 404); AdminPage shared calendar picker; passing tests |
 | ADMIN-03 | 10-01, 10-02, 10-03, 10-04 | Admin routes and UI gated by role check; non-admin cannot reach or invoke | SATISFIED | requireAdmin DB-backed middleware; adminRouter.use('*', requireAdmin) first; isAdmin-gated /admin route; conditional nav; 403 tests pass; e2e redirect tests pass |
 ### Anti-Patterns Found
 | File | Line | Pattern | Severity | Impact |
 |------|------|---------|----------|--------|
 | `apps/api/src/routes/admin.ts` | 114 | `console.error(err.message)` | Info | Logs error message only (not password or request body); acceptable for server-side error visibility |
 | `apps/api/src/routes/me.ts` | 194 | `console.error(err.message)` | Info | Same as above — message only, no credential content |
 No TBD/FIXME/XXX markers found in any phase-modified files.
 ### Known Audit Coverage Limitations
 1. **`apps/api/src/broker/credentialSync.ts`** — sandbox-denied; AES-GCM IV uniqueness, auth-tag verification, and key derivation from APP_PASSWORD_ENCRYPTION_KEY not directly inspected. Observable contract (encrypted at rest, no echo, 400 on CalDAV failure) is covered by 271/271 passing integration tests. Matches 10-REVIEW.md IN-01. Recommend re-review with full read access before production.
 2. **`apps/pwa/src/components/CredentialSheet.tsx`** — sandbox-denied; autoComplete="new-password", invalidateQueries x2, password-state lifetime not directly verified. SetupBanner.tsx comment chain confirms the invalidate(['me']) success path. Matches 10-REVIEW.md IN-01.
 ### Deferred Code Review Warnings (recorded, not blocking)
 - **WR-01** (`apps/api/src/auth/user.ts:118-136`): First-login-wins admin bootstrap is a non-atomic COUNT-then-INSERT. Two concurrent first logins could both receive is_admin=true. Deferred to Phase 12 (the code comment explicitly flags the Phase-12 tightening hook; the bootstrap is the known foundation).
 - **WR-02** (`apps/api/src/routes/me.ts:81-85`): `resolveUserId` coalesces missing OIDC iss/sub to empty string. A compliant Authelia session always carries both; defense-in-depth gap but not an exploitable path in this deployment.
 - **WR-03** (`0001_famous_mad_thinker.sql:11`): UNIQUE(user_id) ADD CONSTRAINT would fail with error 1062 on a deployed environment with duplicate credential rows. No duplicate constraint existed previously; a dev/prod with no duplicates is safe. Deploy runbook should verify before applying migration.
 ### Migration Deviation
 The drizzle-kit-generated file is named `0001_famous_mad_thinker.sql` (drizzle-kit auto-assigned hash name) rather than the plan-expected `0001_v1_1_foundation.sql`. Additionally, `db:migrate` hit a legacy journal-hash mismatch and the executor applied DDL directly via mysql2, recording the migration hash manually. The DDL content is correct, all columns/table are present, and the journal entry is tracked in `meta/_journal.json`. This deviation should be revisited for CI/deploy: the migration must apply cleanly from a fresh DB state in the Gitea CI service container.
 ### Human Verification Required
 None. All observable behaviors were verified programmatically or via passing tests. The following items remain device-only and are out of scope for this phase's verification (consistent with the CLAUDE.md exception for iOS/Safari behavior):
 - CredentialSheet password-field UX on iOS Safari (autoComplete=new-password suppression of keychain)
 - SetupBanner dismissal animation on a physical device

 /**
 * admin.spec.ts — Phase 10 Plan 04 admin route gate
 *
 * Tests:
 *   - Admin user (id=1, seeded is_admin=true by global-setup) sees the Admin nav entry
 *     and reaches /admin with "Admin Settings" heading + Members section.
 *   - Non-admin (route-mocked isAdmin:false) does NOT see the Admin nav entry and is
 *     redirected from /admin to /calendar.
 *
 * Requires the dev stack running with DEV_AUTH_BYPASS=true (see e2e/README.md).
 * global-setup seeds: users id=1 is_admin=true (Plan 10-01 note).
 *
 * Route-mock pattern for non-admin simulation:
 *   page.route('/api/me', ...) → { user: { ..., isAdmin: false, needsProviderSetup: false } }
 *   per [[dev-data-user1-no-calendars]] idiom + lists.spec page.route precedent.
 *
 * Runs on all three device profiles automatically (playwright.config.ts matrix):
 *   iphone:  iPhone 14 / WebKit / 390×844
 *   pixel:   Pixel 7 / Chromium / 412×915
 *   desktop: Desktop Chrome / Chromium / 1280×720
 *
 * Run:
 *   pnpm --filter @familysync/pwa test:e2e
 *   pnpm --filter @familysync/pwa exec playwright test admin.spec.ts
 *   pnpm --filter @familysync/pwa test:e2e -- admin
