Review of 742f376 (Fable). Three defects made the feature not work for the
case it exists for:
- armExpiryWarning() cancelled the alarm before its own early return. Dart
re-pushes the deadline every 60 s with no dedupe (rule 93's ">5 s" dedupe
does not exist), so the first sync after the warning came due deleted the
armed alarm and never re-armed it. Cancel now happens only on the branch
that re-arms.
- cancelSessionWarningAlarm() built its PendingIntent with
FLAG_UPDATE_CURRENT, rewriting the live alarm's RUNTIME_TOKEN to "" so a
delivery in flight was dropped as a stale generation. It now looks the
existing PendingIntent up with FLAG_NO_CREATE.
- SOCKS5 mode never requested POST_NOTIFICATIONS (requestPermission() is
TUN-only because it also raises the VPN consent dialog), so on Android 13+
both alerts were dropped. New plugin method requests it on its own.
Also:
- the native deadline wins the expiry race against the 1 s Dart tick, so the
commonest session end reached _onVpnConnectionChanged as a bare tunnel
drop with no message. It now reconciles and sets the expiry text, with
postAlert false since the native side already posted.
- a resume reconnect no longer resets the support-ad claim: it re-attaches
to the same server session, where the top-up has already been spent.
- RevoltAlerts sets setOnlyAlertOnce so a replacing post does not re-sound.
- AGENTS.md rule 93 described a setSessionExpiry/SESSION_EXPIRES_AT_MS path
that no longer exists, dedupe included. Corrected; that stale text is what
the warning bug was written against.
- CHANGELOG no longer claims the alert covers the tunnel stopping on its own.
flutter analyze clean; debug APK builds.

ReVoltVPN
A free VPN app for Android. Open-source client, transparent infrastructure. Watch an ad, get 2 hours of full-speed traffic — no accounts, no logs, no subscriptions.
How it works
- Watch a short rewarded ad
- Server creates a temporary VLESS session (2 hours / 10 GB)
- Your traffic routes through a single server in Finland at full speed
- When time or data runs out, session ends — watch another ad to continue
- No throttling, no slow lane, no mid-session punishment
No email. No password. No payment. The ad pays for the server.
Protocol
- Transport — VLESS over XHTTP (HTTP/2 multiplexed, path-hidden behind
/revolt) - Obfuscation — Xray Reality spoofs a real website's TLS. To any DPI box, your tunnel looks like a browser visiting that website
- Encryption — TLS 1.3 with borrowed certificate (Reality). No certbot, no domain ownership required
- API — Standard HTTPS to a separate domain. Tunnel destination is IP-pinned — domain compromise is DoS only
Stack

Limitations
- One server, one location (Finland)
- 2 vCPU / 4 GB RAM — not built for thousands of concurrent users
- Android only
