An OS alarm an hour before each upcoming event the user RSVP'd going or
interested to. Because the OS holds the alarm it fires with the app fully
closed — the only closed-app notification achievable without a server.
- src/lib/reminders.ts: schedule/cancel via @capacitor/local-notifications,
tracking handed-out ids in localStorage so withdrawn RSVPs and passed events
are cancelled without disturbing one-off notifications. Web is a no-op.
- src/hooks/useLocalReminders.ts: reuses the existing upcoming-events and
my-RSVPs queries; no new relay destination, no signing.
- Bridge mounts the hook only on native and only when the new 'reminders'
pref is on; unmount cancels everything (opt-out/logout).
- Skipped the Pro-expiry reminder on purpose: it would drag the heavy
useSasquatchPro query into a nudge.
Bumps to v1.5.7 (versionCode 10507); APK rebuilt.
Mirrors the activity the app already computes (bell, crews, DMs, newsletter)
to the OS notification shade, with no new relay traffic and no new network
destination.
- src/lib/osNotify.ts: one delivery API. Web uses the Notification API; native
uses @capacitor/local-notifications (lazily imported, so the web bundle never
pays for it). Tap-through navigates in-app.
- src/components/OsNotificationBridge.tsx: mounted once in Layout, inert until
opted in. Per-source silent priming + a seen-id set means history is never
replayed as a flood, and it stays quiet while the app is visible (the bell
already covers that).
- DMs notify from the gift-wrap ENVELOPE only (src/hooks/useDmEnvelopes.ts,
no decryption) — so Amber is never prompted just to be told you have a
message. Preview is honestly generic.
- src/lib/notificationPrefs.ts + useNotificationPrefs: device-local, opt-in,
default off, per-category toggles. Settings -> Notifications UI.
Deliberately local-only: a fully closed app needs a server push, which is not
built (Phase 2 = on-device background runner; Phase 3 = content-free FCM).
