A third Android build, fcm (io.coinos.beta, "Coinos Beta"): the wallet in its own WebView, as the webview build, with Firebase Cloud Messaging for push on phones with Google Play Services — no distributor app to install. A user on the TWA APK found launching slow next to Minibits (2026-11-05); measured on a Pixel 9, a WebView paints ~0.7 s sooner than a cold Chrome. This build installs beside the TWA for a side-by-side trial before deciding whether it replaces it. Fcm asks for the token and stores "fcm:<token>" as the push endpoint, which reaches the page down the UnifiedPush road (?up= on the next launch, or written straight into the page's localStorage once it has loaded, since the token arrives after the first load starts); nwcpush (coinosv3-server 0c50417) sends an fcm: endpoint through Firebase. FcmService hands a message's "body" to the same handler UnifiedPush messages use (PushReceiver.onPush: wake the wallet off-screen, notify unless it answered a silent request). Firebase is set up in code (CoinosApp → Fcm.init) from values build.gradle reads out of app/google-services.json (gitignored) — without it the build still builds and falls back to UnifiedPush. The webview and fdroid builds get a stub Fcm (src/nofcm) and carry no Google code; the notification permission is asked when Firebase or a distributor can deliver; CoinosHost.env reports app "fcm"
