+# Android Smoke & Baseline
+
+## Smoke run (before merge/release)
+1. Auth: login with valid credentials, app relaunch auto-login, invalid password error.
+2. Chat list: All/Archived tabs, local search, pull-to-refresh.
+3. Realtime: new message appears without restart, reconnect after temporary network off/on.
+4. Chat screen: send text, reply, edit, delete, forward, reaction toggle.
+5. Media: send image/file/audio, image opens in viewer, audio play/pause works.
+6. Invite flow: join-by-invite token from Chat List opens joined chat.
+7. Session safety: expired access token refreshes transparently for API calls.
+
+## Baseline targets (initial)
+- Cold start to first interactive screen: <= 2.5s on mid device.
+- Chat list first render after app open: <= 1.2s with warm cache.
+- Scroll in chat list/chat history: no visible jank in normal usage.
+- Crash-free smoke run: 0 crashes / 0 ANRs.
+
+## Commands
+- Build: `./gradlew :app:assembleDebug`
+- Unit tests: `./gradlew :app:testDebugUnitTest`
+- Kotlin compile only: `./gradlew :app:compileDebugKotlin`
