In-tab notification bridge so the operator gets a system notification
when a reminder fires successfully (or partly / fails) and when a
send-test message lands. Foundation for true background push later
(VAPID + service-worker subscription); this lands the wiring so
behaviour is testable today.
Pieces
------
- `lib/notifications.ts` — pure helper module:
* notificationSupport / getPermission — feature detection that
treats the SSR / unsupported-browser case as "denied" so callers
don't have to handle a third state.
* isOptedIn / setOptedIn — localStorage-backed opt-in flag
(key `cmbot.notifications.optedIn`). Survives gracefully when
window is missing or storage throws (private mode / quota).
* showNotification(opts) — gated dispatch returning a discriminated
result ({ ok: true, tag } | { ok: false, reason }) so callers
can fall back to a UI toast on opt-out / unsupported / error.
* reminderFiredToNotification + sendTestDoneToNotification —
pure mappers from the bot's SSE events into notification args.
Skips bookkeeping noise (status === "skipped") and failures
that the in-page toast already shows verbatim.
- `components/notification-manager.tsx` — client component mounted
once at the app shell. Subscribes to `reminder.fired` and
`send_test.done` via useEvents and forwards each through the pure
mappers. Renders no DOM.
- `components/notifications-toggle.tsx` — settings-page card with
three states (unsupported / not-granted / granted+opted-in).
"Send test" button fires a sample notification so the operator
can verify the wiring without waiting for a real reminder. The
blocked-by-browser path points them at site settings instead of
silently doing nothing.
- `app/settings/page.tsx` — new "Notifications" card sits above
the Appearance card.
- `app/layout.tsx` — `<NotificationManager />` rendered alongside
`<Toaster />` inside ThemeProvider so the SSE subscription is
active across all routes.
Bot side
--------
- `apps/bot/src/scheduler/fire-reminder.ts` — emits
`pgNotifyWeb({ type: "reminder.fired", reminderId, runId, status })`
after every run regardless of success/partial/failed. The web
side decides whether to surface it as a notification (skipped is
filtered out client-side).
- send_test.done was already emitted by `ipc/send-test-handler.ts`.
PWA service-worker tests (the original ask before this thread)
--------------------------------------------------------------
- Extracted the Serwist config into `pwa/config.ts` so the choices
(skipWaiting, clientsClaim, navigationPreload, runtimeCaching,
precacheEntries) are pinnable without booting a worker scope.
- 6 tests in `pwa/config.test.ts` lock the surface (no extra keys
appear silently, the manifest passes through unchanged, the
pinned booleans stay where production expects them).
- 6 tests in `app/manifest.webmanifest/route.test.ts` cover the
manifest contract (display=standalone, start_url=/, dark theme
colors match the OS, both icons are PNG + maskable, paths
match committed PNGs in public/).
Test counts
-----------
281 web + 31 shared + 26 bot = 338 total (was 306).
- +6 pwa/config (service-worker config pinning)
- +6 app/manifest.webmanifest (PWA manifest contract)
- +20 lib/notifications (full coverage of mappers + dispatch
gates + SSR / unsupported / blocked / opted-out paths)

The web app is now installable on a phone home screen with offline
fallback for static assets and the navigation shell.
Pieces
------
- `src/app/manifest.webmanifest/route.ts` — dynamic manifest route.
Standalone display mode, portrait orientation, dark theme matching
the app, "any maskable" icons so the same PNG works for both
regular launchers and Android adaptive icons.
- `src/pwa/sw.ts` — service worker entry. Uses serwist's stock
recipe: skipWaiting + clientsClaim so a new worker takes over on
the next navigation, navigationPreload to race the network with
the worker boot, and `defaultCache` for HTML-network-first /
static-cache-first / image+font cache TTLs.
- `next.config.ts` — wraps the existing config with `withSerwistInit`.
Disabled in development (`NODE_ENV !== "production"`) because a
service worker on every dev reload makes hot-reload extremely
flaky.
- `package.json` build script switched to `next build --webpack`.
`@serwist/next` doesn't yet support Turbopack (it logs a warning
and silently skips emitting `sw.js`), and Next 16 defaults the
build to Turbopack. The dev server still uses Turbopack — only
production builds switch to webpack.
- `src/app/layout.tsx` metadata gains `manifest`, `icons.icon` (192
+ 512 PNG), and `icons.apple` (180 PNG). The existing
`appleWebApp.capable` already opts iOS into standalone mode.
Icons
-----
Generated by a tiny one-shot script (`scripts/gen-pwa-icons.ts`)
that uses the workspace's already-installed sharp to render an SVG
wordmark at 512 / 192 / 180 px. Placeholder branding (dark square
with "cm" wordmark) — swap in real artwork later by editing the SVG
in the script and re-running `pnpm --filter @cmbot/web run gen:icons`.
Build artefacts
---------------
- `apps/web/public/icon-512.png`, `icon-192.png`,
`apple-touch-icon.png` ARE committed (stable input).
- `apps/web/public/sw.js` and `swe-worker-*.js` are NOT — they're
regenerated on every production build. Added to `.gitignore`.
Verification
------------
- Production build emits `[serwist] Bundling the service worker
script with the URL '/sw.js' and the scope '/'...` and `sw.js`
shows up in `public/`.
- `/manifest.webmanifest` is in the build's static-route table.
- 249 web tests still passing.
