Amber blobs were cold (blue/indigo) but web uses warm (gold/coral/honey/teal).
Mono had slate chroma but web is pure achromatic (zero chroma).
Aurora dark primary was magenta but web swaps to gold in dark mode.
All four themes now pixel-match the web app's OKLCH values.
Foundation for the premium UI overhaul:
- P3 DisplayP3 color pipeline (all tokens in wide gamut)
- SquircleShape (iOS-style superellipse with G2 continuity)
- KaizenShapes token system (xs/sm/md/lg/xl/pill/circle)
- Multi-layer ShadowStack system (level 0–4)
- GlassSurface composable with RenderEffect blur + API fallback
- Motion tokens (easing curves, spring specs, durations)
- Tilt sensor state (GAME_ROTATION_VECTOR, lifecycle-aware)
- 4-theme system (Amber/Blau/Mono/Aurora) with AccentScheme
- ThemeRegistry + CompositionLocal for accent propagation
- Unit tests for colors, shapes, shadows, themes
kotlinx.serialization defaults to not encoding properties with default
values. SaveMessage.kind = "chat" was never sent, causing the backend's
sanitizeSaveableMessage() to reject every save with 400. This also
broke title generation since it was gated behind a successful save.
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.
- Parse and render message attachments from loaded conversations (images
inline via OkHttp + in-memory cache, other kinds as icon chips)
- Wire up the + button with Android file picker (ActivityResultContracts)
- Upload files to /api/v1/upload with progress tracking and preview chips
- Send attachments with chat requests and persist them in saved messages
- Markdown: horizontal rules, blockquotes, links, code block copy button
Replace null-returning fetchModels/fetchConversations with FetchResult<T>
sealed interface. Error banner now shows the exact cause (HTTP status,
DNS, SSL, timeout, JSON parsing) instead of "Verbindung zum Server
fehlgeschlagen".
- 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
Sidebar now lists the user's conversations from GET /api/v1/conversations
(date-grouped, pinned first, active highlighted) instead of mock data. Sending
creates a server conversation on the first message, persists each exchange via
POST .../messages, and auto-titles new conversations. Tapping a chat loads its
stored messages; new-chat/logout reset the active conversation. Linear model
(no branching); locked chats are skipped (no in-app unlock yet).
Top pill shows the active model; tapping opens a bottom sheet with a
response-speed segment (Instant/Normal/Max -> reasoningEffort + throughput),
model search, favorites, provider grouping and a Vertex hoster badge.
Model/speed/favorites persisted in the encrypted store; chat now sends the
additive reasoningEffort/preferThroughput v1 fields.
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).
