Room 2.8.4 as local SQLite read-cache for conversations and messages.
Sidebar and chat history load instantly from cache, background refresh
syncs with the server. Streaming stays in-memory, flushed to Room after
completion. Includes ChatViewModel, repositories, mappers, TypeConverters,
and unit tests.
- Eliminate recomposition hell: isolate auto-scroll via derivedStateOf + snapshotFlow
- Preserve partial response on connection drop instead of replacing with error
- O(1) incremental stream parser (StreamConsumer.Incremental) replacing O(N²) re-scan
- Parallel conversation creation via async/await to reduce TTFT
- TCP/TLS prewarm on app resume via LifecycleResumeEffect
- Surface API failures with Log.w and UI error banner instead of silent emptyList()
- Fix nullable KaizenModel.name crash in ModelSheet
Replaces the Phase-0 fakeReply mock with the real v1 API. Deployment-agnostic:
one binary, one Authorization: Bearer contract, server-URL field switches between
the official instance and any self-host.
- auth/LoginScreen: server-URL + email + password -> POST /api/v1/auth/token
- net/SecureStore: kzn_ token in EncryptedSharedPreferences (KeyStore AES-256-GCM)
- net/SessionViewModel: snapshot-state login/logout routing, restores on launch
- net/KaizenApi: POST /api/v1/chat streaming + GET /api/v1/me for the default model
- net/StreamConsumer: Kotlin port of lib/chat/stream-consumer.ts (JVM-unit-tested)
- deps: okhttp, kotlinx-serialization, security-crypto; INTERNET permission
Code-complete; not yet built/run on device (no Android SDK on the dev Mac).
