The architecture is sound: VAPID signing is delegated to `web-push`, the D-03 actor-suppression filter is applied both at the DB layer and in application code, `event.waitUntil()` is used correctly in the SW, and the D-13 boundary (no tsdav in notification code) is respected. +All 12 original findings plus the 2 fix-induced findings are resolved: +- **NEW-CR-01** (iOS gesture gate re-broken by `await navigator.serviceWorker.ready` in the tap path) — FIXED in `c7ef581`. `PushPermissionPrompt.tsx` and `SettingsSheet.tsx` now pre-resolve both the SW registration and VAPID key into state via `useEffect`, disable the Enable control until both are ready, and call `subscribe(registration, vapidKey)` synchronously — zero `await` between the user gesture and `pushManager.subscribe()`. Manually verified. +- **NEW-WR-01** (whole-cache-clear delete branch emitted no `delete` change events) — FIXED in `17756fc`, with a new regression test in `sync.test.ts`. -Four blockers were found. Two are correctness bugs: (1) the `sentReminders` set in `reminderScheduler.ts` grows without bound and is never pruned — it will leak memory and eventually begin skipping due reminders after a process restart populates a new set without stale guard entries; (2) the `uniq_push_endpoint` unique constraint is defined on a `text` column in the migration SQL, which MariaDB/InnoDB silently truncates to 767 bytes when creating the index — a subscription with a very long endpoint can collide with or fail to match a different subscription, causing phantom prune-without-delete or missed 410 cleanup. Two are security: (3) `VAPID_PRIVATE_KEY` is passed via `docker-compose.yml` environment block from the host `.env` but with no fallback (`${VAPID_PRIVATE_KEY}` with no `:-` default) — Docker Compose will error at startup if the variable is unset rather than leaving push non-functional, which is correct, but the VAPID private key has no runtime check that it is well-formed before `setVapidDetails` is called, and invalid keys are only warned, not blocked; and (4) the `notificationclick` handler in `sw.ts` uses `client.url === url` for exact-URL matching, which means a focused-window match will never fire for notifications with query-string deep-links whose current window URL does not exactly match (e.g. `/calendar?date=2026-06-09&event=uid` vs `/calendar`) — this is a functional regression, not a security issue, but is reclassified as a correctness blocker because the D-14 deep-link requirement is unmet for the most common case. +Final state: api + pwa typecheck clean; PWA builds; API suite 214 tests (one occasional flaky real-DB timeout in `lists.test.ts` under full-suite parallel load — passes 59/59 in isolation; test-infra timing, not a code defect). + +## Summary (historical — pre-fix) + +This is an --auto re-review after a fix pass claiming to resolve all 12 prior findings.

Entries are never removed. For an app running continuously with N shared events, the set grows by N entries/minute indefinitely. After a long uptime the set consumes significant memory. More critically: the deduplication key includes `minuteBucket = floor(ms / 60000)`, so after a process restart the set is empty and an event that fired in the previous minute (same wall-clock minute bucket) will fire again — the dedup logic is only effective within a single process lifetime. This is documented as "acceptable data loss on restart" for the double-fire case, but the unbounded growth is not documented and constitutes a bug. - -**Fix:** Prune entries for past minute buckets after each scan. After the dispatch loop completes, remove any set entry whose minuteBucket is strictly less than `currentBucket - 1`: +**Issue:** The fix for CR-04 correctly moves `fetchVapidKey` out of `subscribe()` and pre-fetches +the VAPID key into state (`vapidKey`). However, the tap handler (`handleEnableClick`) wraps the +call in an immediately-invoked async IIFE: ```typescript -// After the dispatch loop in runReminderCheck(): -const staleBucket = minuteBucket - 1 -for (const key of sentReminders) { - const [, bucketStr] = key.split(':') - if (Number(bucketStr) < staleBucket) { - sentReminders.delete(key) - } +void (async () => { + try { + const registration = await navigator.serviceWorker.ready // ← AWAIT before subscribe() + await subscribe(registration, resolvedVapidKey) // ← pushManager.subscribe inside + ... +})() +``` + +`navigator.serviceWorker.ready` is a `Promise`. On iOS, the gesture +gate requires `pushManager.subscribe()` to be called synchronously within the user-gesture call +stack. The `await navigator.serviceWorker.ready` that precedes `subscribe()` yields the microtask +queue before `pushManager.subscribe()` is ever called — on a cache miss or slow SW activation this +is an async network/IPC round-trip, which breaks the gesture gate and produces `NotAllowedError` +on iOS exactly as the original `await fetchVapidKey()` did. + +`navigator.serviceWorker.ready` resolves immediately only when the SW is already active and +controlling the page. In that common steady-state case iOS may not enforce the synchrony +requirement strictly. But on first install (SW just activated, `ready` may take >1 frame to +resolve) or after a SW update cycle, the await is observable and iOS will reject with +`NotAllowedError`. + +The same pattern is present in `SettingsSheet.tsx:115`: +```typescript +const registration = await navigator.serviceWorker?.ready // ← same problem +if (registration) { + await subscribe(registration, resolvedVapidKey) } ``` ---- - -### CR-02: `uniq_push_endpoint` Unique Constraint on `text` Column Will Silently Truncate in MariaDB/InnoDB - -**File:** `apps/api/src/db/migrations/0003_same_xavin.sql:10` and `apps/api/src/db/schema.ts:243-244` - -**Issue:** `endpoint` is declared `text NOT NULL` in both the schema and migration, and `CONSTRAINT uniq_push_endpoint UNIQUE(endpoint)` is applied to it. MariaDB/InnoDB cannot index an unbounded `text` column directly — it requires a prefix length. The behavior differs by server version and `innodb_large_prefix` setting: some versions silently create a prefix index (767 bytes by default, 3072 bytes with `ROW_FORMAT=DYNAMIC`), others fail. In either case a silent prefix match means two endpoints that share the same first 767 characters — which is possible for push endpoints from the same push service domain — are treated as duplicates. This makes the upsert in `push.ts`'s `onDuplicateKeyUpdate` unreliable: a second distinct subscription may silently collide, or the migration may fail entirely on strict-mode MariaDB. - -The correct fix is to define `endpoint` as `varchar(2048)` (matching the Zod validation bound of `z.string().url().max(2048)` in `routes/push.ts:61`) in both the schema and migration. - -**Fix:** -```sql --- Migration: change endpoint column type -ALTER TABLE `push_subscriptions` - MODIFY COLUMN `endpoint` varchar(2048) NOT NULL; - --- Schema: change text() to varchar -endpoint: varchar('endpoint', { length: 2048 }).notNull(), -``` - -The Zod schema in `push.ts` already enforces `max(2048)`, so server-validated inputs fit within the column. Update `p256dh` similarly — it is also `text` but a `varchar(512)` would match the Zod bound. - ---- - -### CR-03: `notificationclick` Deep-Link Window Focus Uses Exact URL Match — D-14 Never Fires for Query-String Deep-Links - -**File:** `apps/pwa/src/sw.ts:154` - -**Issue:** The `notificationclick` handler matches `client.url === url` to find an existing window. Push deep-link URLs for event notifications are of the form `/calendar?event=` or `/calendar?date=&event=`. When the user has the PWA open on `/calendar` (the root path, no query string), `client.url` will be `https://host/calendar` but `url` will be `https://host/calendar?event=uid` — the exact comparison fails, so the handler falls through to `openWindow` and opens a second PWA window instead of focusing the existing one. On iOS standalone mode, `openWindow` does NOT open a second window; it navigates the existing window, so the net behavior is correct on iOS. On Android Chrome it opens a second window. The deeper problem: the handler never navigates the focused window to the deep-link URL; it only calls `focus()` without `navigate()` — so even when the match succeeds (notification for the currently-open URL), the window is focused at the current route, not the notification target. - -**Fix:** Use `clients.matchAll` to find any window on the same origin, focus it, and call `client.navigate(url)`: +**Fix:** Pre-fetch `navigator.serviceWorker.ready` into state alongside `vapidKey`, using a +parallel `useEffect`. Then the tap handler has synchronous access to both: ```typescript -self.addEventListener('notificationclick', (event: NotificationEvent) => { - event.notification.close() - const url: string = - typeof event.notification.data?.url === 'string' - ? event.notification.data.url - : '/' +// In PushPermissionPrompt (and SettingsSheet equivalently): +const [swRegistration, setSwRegistration] = useState(null) - event.waitUntil( - self.clients - .matchAll({ type: 'window', includeUncontrolled: true }) - .then((clientList) => { - // Focus any existing window on this origin and navigate it - for (const client of clientList) { - if ('focus' in client) { - return (client as WindowClient).focus().then(() => - (client as WindowClient).navigate(url) - ) - } - } - if (self.clients.openWindow) { - return self.clients.openWindow(url) - } - }), - ) -}) -``` - ---- - -### CR-04: `subscribe()` in `usePushSubscription` Calls `fetchVapidKey()` (an async `await`) Before `pushManager.subscribe()` — iOS Gesture Gate May Be Broken on Cache Miss - -**File:** `apps/pwa/src/hooks/usePushSubscription.ts:197-206` - -**Issue:** The `subscribe()` function unconditionally `await`s `fetchVapidKey()` before calling `registration.pushManager.subscribe()`. The comment says "Fetch VAPID key (from cache if already prefetched)" and the VAPID key is pre-fetched in a `useEffect` by `PushPermissionPrompt`. However: - -1. The `useEffect` pre-fetch is fire-and-forget (`void prefetchVapidKey()`). There is no guarantee it completes before the user taps "Enable Notifications" — especially on a slow connection on first install. -2. If `sessionStorage` is unavailable (private mode, quota exceeded) or the pre-fetch failed silently, `fetchVapidKey()` will make a network round-trip inside `subscribe()`. -3. iOS requires `pushManager.subscribe()` to be called synchronously within the user gesture's call stack. An `await fetch(...)` before `pushManager.subscribe()` breaks the gesture gate — the iOS browser will throw `NotAllowedError` with the message "The operation was not permitted." The existing code has this `await` on the very first line of `subscribe()`. - -The `setEnabled(true)` path in the same hook has the same structure (`await fetchVapidKey()` before `pushManager.subscribe()`), but `setEnabled(true)` is only called when `Notification.permission === 'granted'` (OS already approved), so no OS dialog is shown — the gesture gate for permission is not relevant there. For the `subscribe()` path used from `PushPermissionPrompt` and `SettingsSheet`, the gate IS relevant when `Notification.permission === 'default'`. - -**Fix:** Pre-fetch the VAPID key synchronously into a variable before the tap, and pass it as an argument to `subscribe()`. Remove the `fetchVapidKey()` call from inside `subscribe()`: - -```typescript -// In PushPermissionPrompt: pre-fetch before the button renders -const [vapidKey, setVapidKey] = useState(null) useEffect(() => { - fetchVapidKey().then(setVapidKey).catch(() => {}) -}, []) + if (!installed || permission !== 'default' || dismissed) return + void navigator.serviceWorker?.ready.then(setSwRegistration).catch(() => {}) +}, [installed, permission, dismissed]) -// subscribe() signature change: -const subscribe = async ( - registration: ServiceWorkerRegistration, - vapidKey: string, -): Promise => { - // No await before this line — iOS gesture gate preserved - const sub = await registration.pushManager.subscribe({ - userVisibleOnly: true, - applicationServerKey: urlBase64ToUint8Array(vapidKey), +// Disable button until BOTH are ready +
