hailin 2ce0e7cdd4 fix: use external LiveKit URL in voice-service config
The livekit_ws_url returned in token response needs to be the external
server address, not the internal Docker network name, so Flutter clients
can connect directly.

hailin acfdae7773 fix: use livekit-api package for voice-service token endpoint
The livekit package is the client SDK and doesn't include the server-side
API module. Switch to livekit-api which provides AccessToken, VideoGrants,
RoomAgentDispatch, and RoomConfiguration needed for token generation.

hailin 94a14b3104 feat: migrate voice call from WebSocket/PCM to LiveKit WebRTC
实时语音对话架构迁移:WebSocket → LiveKit WebRTC

## 背景
原语音通话架构基于 FastAPI WebSocket 传输原始 PCM,管道串行执行
(VAD → 批量STT → Agent → 攒句 → 批量TTS),首音频延迟约 6 秒。
迁移到 LiveKit Agents 框架后,利用 WebRTC 传输 + 流水线并行,
预期延迟降至 1.5-2 秒。

## 架构
Flutter App ←── WebRTC (Opus/UDP) ──→ LiveKit Server ←──→ Voice Agent
  livekit_client                      (自部署, Go)       (Python, LiveKit Agents SDK)
                                                          ├─ VAD (Silero)
                                                          ├─ STT (faster-whisper / OpenAI)
                                                          ├─ LLM (自定义插件 → agent-service)
                                                          └─ TTS (Kokoro / OpenAI)

关键设计:LLM 不直接调用 Claude API,而是通过自定义插件代理到现有
agent-service,保留 Tool Use、会话历史、租户隔离等能力。

## 新增服务

### voice-agent (packages/services/voice-agent/)
LiveKit Agent Worker,包含:
- agent.py: 入口,prewarm() 预加载模型,entrypoint() 编排会话
- plugins/agent_llm.py: 自定义 LLM 插件,代理 agent-service API
  - POST /api/v1/agent/tasks 创建任务
  - WS /ws/agent 订阅流式事件 (stream_event)
  - 跨轮复用 session_id 保持对话上下文
- plugins/whisper_stt.py: 本地 faster-whisper STT (批量识别)
- plugins/kokoro_tts.py: 本地 Kokoro-82M TTS (24kHz PCM)
- config.py: pydantic-settings 配置

### LiveKit Server (deploy/docker/)
- livekit.yaml: 信令端口 7880, RTC TCP 7881, UDP 50000-50200
- docker-compose.yml: 新增 livekit-server + voice-agent 容器

### LiveKit Token 端点
- voice-service/src/api/livekit_token.py:
  POST /api/v1/voice/livekit/token
  生成 Room JWT,嵌入 auth_header 到 AgentDispatch metadata

## Flutter 客户端改造
- agent_call_page.dart: 从 ~814 行简化到 ~380 行
  - 替换: WebSocketChannel, AudioRecorder, PcmPlayer, 手动心跳/重连
  - 使用: Room.connect(), setMicrophoneEnabled(true), LiveKit 事件监听
  - 波形动画改用 participant.audioLevel
- pubspec.yaml: 添加 livekit_client: ^2.3.0
- app_config.dart: 增加 livekitUrl 字段
- api_endpoints.dart: 增加 livekitToken 端点

## 配置说明 (环境变量)
- STT_PROVIDER: local (默认, faster-whisper) / openai
- TTS_PROVIDER: local (默认, Kokoro) / openai
- WHISPER_MODEL: base (默认) / small / medium / large
- WHISPER_LANGUAGE: zh (默认)
- KOKORO_VOICE: zf_xiaoxiao (默认)
- DEVICE: cpu (默认) / cuda

## 不变的部分
- agent-service: 完全不改,voice-agent 通过现有 API 调用
- voice-service 核心: pipeline/STT/TTS/VAD 保留 (Twilio 备用)
- Kong 网关: 现有路由不变
- 数据库: 无 schema 变更

hailin c9367ee22a fix: PDF attachments sent as document blocks instead of image blocks
PDF files were incorrectly wrapped as type:'image' content blocks,

  use type:'document' block (Anthropic native PDF support) instead
- claude-agent-sdk-engine: detect both 'image' and 'document' blocks

hailin ed39518a71 feat: floating pill input bar + auto-scroll on history load
Input area redesign (ChatGPT/Claude App style):
- Replace fixed bottom bar with floating pill overlay using Stack+Positioned
- Semi-transparent background (surface 92% opacity) with rounded corners (28px)
- Drop shadow for depth separation from content
- Remove inner TextField border (InputBorder.none) for cleaner look
- ListView bottom padding increased to 80px to leave room under the pill
- Input pill floats 12px from edges, 8px from bottom

History scroll fix:
- Add jump parameter to _scrollToBottom() for instant positioning
- When loading conversation history (empty→many messages), use jumpTo
  instead of animateTo to avoid incomplete scroll on large message lists
- Double-frame jumpTo ensures layout settles before final scroll position

hailin e4c2505048 feat: add multimodal image input with streaming markdown optimization
Two major features in this commit:

1. Streaming Markdown Rendering Optimization
   - Replace deprecated flutter_markdown with gpt_markdown (active, AI-optimized)
   - Real-time markdown rendering during streaming (was showing raw syntax)
   - Solid block cursor (█) instead of AnimationController blink
   - 80ms token throttle buffer reducing rebuilds from per-token to ~12.5/sec
   - RepaintBoundary isolation for markdown widget repaints
   - StreamTextWidget simplified from StatefulWidget to StatelessWidget

2. Multimodal Image Input (camera + gallery + display)
   - Flutter: image_picker for gallery/camera, base64 encoding, attachment
     preview strip with delete, thumbnails in sent messages
   - Data layer: List<String>? → List<Map<String, dynamic>>? for structured
     attachment payloads through datasource/repository/usecase
   - ChatAttachment model with base64Data, mediaType, fileName
   - ChatMessage entity + ChatMessageModel both support attachments field
   - Backend DTO, Entity (JSONB), Controller, ConversationContextService
     all extended to receive, store, and reconstruct Anthropic image
     content blocks in loadContext()
   - Claude API engine skips duplicate user message when history already
     ends with multimodal content blocks
   - NestJS body parser limit raised to 10MB for base64 image payloads
   - Android CAMERA permission added to manifest
   - Image.memory uses cacheWidth/cacheHeight for memory efficiency
   - Max 5 images per message enforced in UI

Data flow:
  ImagePicker → base64Encode → ChatAttachment → POST body →
  DB (JSONB) → loadContext → Anthropic image content blocks → Claude API

hailin 89f0f6134d fix: resolve bottom overflow issues in chat page timeline rendering
Three root causes fixed:

1. TimelineEventNode: Replaced IntrinsicHeight (which forces intrinsic
   height calculation on unbounded content) with CustomPaint-based
   _TimelineLinePainter that draws vertical lines based on actual
   rendered widget size. Also added maxLines/ellipsis to label text
   and mainAxisSize.min on inner Column.

2. ApprovalActionCard: Changed countdown + action buttons layout from
   Row with Spacer (which requires infinite width) to Wrap with
   spacing, preventing horizontal overflow on narrow screens.

3. AnimatedCrossFade in _CollapsibleCodeBlock and _CollapsibleThinking:
   Wrapped with ClipRect and added sizeCurve: Curves.easeInOut to
   prevent the outgoing child from extending beyond parent bounds
   during the cross-fade transition.

hailin 50dbb641a3 fix: comprehensive hardening of agent task cancel/inject/approve flows
6 rounds of systematic audit identified and fixed 14 bugs across
backend controller and Flutter client:

## Backend (agent.controller.ts)

Security & Tenant Isolation:
- Add @TenantId + ForbiddenException check to cancelTask, injectMessage,
  approveCommand — all 4 write endpoints now enforce tenant isolation
- Add tenantId check on session reuse in executeTask to prevent
  cross-tenant session hijacking

Architecture & Correctness:
- Extract shared runTaskStream() from inline fire-and-forget block,
  used by both executeTask and injectMessage to reduce duplication
- Use session.engineType (not getActiveEngine()) in cancelTask,
  injectMessage, approveCommand — fixes wrong-engine-cancel when
  global engine config is switched after task creation
- Add concurrent task prevention: executeTask checks for existing
  RUNNING task on same session and cancels it before starting new one
- Add runningTasks Map to track task promises, awaitTaskCleanup()
  helper with 3s timeout for inject to wait for partial text save
- captureSdkSessionId() captures SDK session ID into metadata
  without DB save (callers persist), preventing fire-and-forget race

Cancel/Reject Improvements:
- cancelTask: idempotent (returns early if already CANCELLED/COMPLETED),
  session stays 'active' (was 'cancelled'), emits cancelled WS event
- approveCommand reject: session stays 'active' (was 'cancelled'),
  now emits cancelled WS event so Flutter stream listeners clean up
- approveCommand approved: collect text events and save assistant
  response to conversation history on completion (was missing)

Minor:
- task.result! non-null assertion → task.result ?? 'Unknown error'
- Add findRunningBySessionId() to TaskRepository

## Flutter

API Contract Fix:
- approveCommand: route changed from /api/v1/ops/approvals/:id/approve
  to /api/v1/agent/tasks/:id/approve with {approved: true} body
- rejectCommand: route changed from /api/v1/ops/approvals/:id/reject
  to /api/v1/agent/tasks/:id/approve with {approved: false} body

Resource Management:
- ChatNotifier.dispose() now disconnects WebSocket to prevent
  connection leak when navigating away from chat

hailin d5f663f7af feat: inject-message support for mid-stream task interruption
Backend (agent-engine.port.ts):
- Add `cancelled` event type: emitted when a task is cancelled (user-initiated
  or injection), so Flutter can close the old stream cleanly
- Add `task_info` event type: emitted after inject to pass the new taskId to
  the client, enabling cancel/re-inject on the replacement task

Flutter (features/chat/):
- ChatState: track current `taskId` alongside `sessionId`; clear on completion
  or error
- Handle `TaskInfoEvent`: update taskId in state when server issues a new task
- Handle `CancelledEvent`: treat as stream termination (agentStatus → idle)
- MessageType.interrupted: new UI node (warning style) for mid-stream cancels
- _inject(): send text as an inject request while streaming; backend cancels
  the current task and starts a new one with the injected message
- Input area: during streaming, hint changes to "追加指令...", Enter key calls
  _inject() instead of _send(), and both inject-send + stop buttons are shown
- isAwaitingApproval kept separate from isStreaming so approval flow is not
  blocked by inject mode

hailin ce4e7840ec fix: route AgentSkillService to per-tenant schema to match SDK engine
Previously AgentSkillService wrote skills to public.agent_skills (TypeORM
entity with tenantId column filter), while ClaudeAgentSdkEngine read from
it0_t_{tenantId}.skills (per-tenant schema). The two tables were never
connected, so any skill added via the CRUD API was invisible to the agent.

This fix:
- Rewrites AgentSkillService to use DataSource + raw SQL against the
  per-tenant schema it0_t_{tenantId}.skills
- Maps API fields: script→content, enabled→is_active
- Removes AgentSkillRepository and AgentSkill entity from module (no longer needed)
- CRUD API response shape is unchanged (fields mapped back to script/enabled)

hailin bc7e32061a fix: improve voice call reconnection robustness
Server side (session_router.py):
- /reconnect now accepts sessions in "active" state (not just "disconnected")
- When client reconnects to an active session, the old WebSocket/pipeline is
  automatically replaced when the new WebSocket connects
- Only truly terminal states (e.g. "ended") return 409

Flutter side (agent_call_page.dart):
- Distinguish terminal errors (404 session gone, 409 ended) from transient
  errors (network timeout, server unreachable) in reconnect loop
- Terminal errors break immediately instead of wasting retry attempts
- Extract _connectWebSocket() helper for cleaner reconnect flow
- Add DioException handling for proper HTTP status code inspection

FlutterSoundPlayer.feedUint8FromStream() requires interleaved mode.
With interleaved=false, every feed() call threw:
  "Cannot feed with UInt8 with non interleaved mode"

- feedUint8FromStream (Uint8List) → requires interleaved: true
- feedFromStream (Float32List) → requires interleaved: false
Since we feed raw PCM bytes (Uint8List), interleaved must be true.

hailin e706a4cdc7 fix: enable simultaneous playback + recording in voice call
Root cause: PcmPlayer called openPlayer() without audio session config,
so Android defaulted to earpiece-only mode. When the mic was actively
recording, playback was silently suppressed — the agent's TTS audio was
sent successfully over WebSocket but never reached the speaker.

Changes:

1. PcmPlayer (pcm_player.dart):
   - Added audio_session package for proper audio session management
   - Configure AudioSession with playAndRecord category so mic + speaker
     work simultaneously
   - Set voiceCommunication usage to enable Android hardware AEC (echo
     cancellation) — prevents feedback loops when speaker is active
   - defaultToSpeaker routes output to loudspeaker instead of earpiece
   - Restored setSpeakerOn() method stub (used by UI toggle)

2. AgentCallPage (agent_call_page.dart):
   - Fixed fire-and-forget bug: _pcmPlayer.feed() returns Future but was
     called without await, causing interleaved feedUint8FromStream calls
   - Added _feedChain serializer to guarantee sequential audio feeding

3. Dependencies:
   - Added audio_session package to pubspec.yaml

startup. This allows switching between Local and OpenAI providers in the

hailin 7b71a4f2fc fix: properly close WebSocket with subscription cancel + fire-and-forget
Root cause: IOWebSocketChannel.sink.close() can hang indefinitely
(dart-lang/web_socket_channel#185). Previous fix used unawaited close
but didn't cancel the stream subscription, so the old listener could
still push events to _messageController.

Fix: Extract _closeCurrentConnection() that:
1. Cancels StreamSubscription first (stops duplicate events immediately)
2. Fire-and-forget sink.close(goingAway) (frees underlying socket)

This follows the workaround recommended in the official issue tracker.

hailin 45eb6bc453 fix: use unawaited close to prevent WebSocket reconnect hang
The await on sink.close() blocks indefinitely when the server doesn't
respond to the close handshake. Use fire-and-forget with unawaited()
so the new connection can proceed immediately.

hailin 3185438f36 fix: close previous WebSocket before opening new connection
When sending a second message in the same session, the old WebSocket
connection was not closed, causing both connections to subscribe to the
same session room. This resulted in each text event being received twice,
producing garbled/duplicated output text.

hailin e02b350043 fix: create /data/claude-tenants dir with appuser ownership in Dockerfile
Without this, the SDK engine fails to create tenant HOME directories
because the Docker volume mount point doesn't exist and appuser lacks
write permissions.

hailin cc0f06e2be feat: SDK engine native resume with per-tenant HOME isolation
Replace prompt-prefix workaround with SDK's native resume mechanism.
Each tenant gets isolated HOME directory (/data/claude-tenants/{tenantId})
to prevent cross-tenant session file mixing. SDK session IDs are persisted
in session.metadata for cross-request resume support.
