 # CURRENT TASK
 
-**Feature**: F008 — Permission bridge + confirm UI + allowlist + audit log
+**Feature**: F009 — Chat UI + session continuity + project picker
 **Phase**: Phase 03 — AI (Claude Code bridge)
-**Status**: COMPLETE (PR #9 ready)
+**Status**: COMPLETE (Ready for PR & merge)
 
 ## Exact next steps
 1. **Protocol definitions (`packages/protocol`)**:
-   - `RiskHint` enum: `"low" | "medium" | "high"`
-   - `classifyRisk(toolName: string, input: Record<string, unknown>)`: pure risk classifier
-   - `isReadonlyCommand(toolName: string, input: Record<string, unknown>)`: pure allowlist check
-   - `perm.request` message (requestId, toolName, command, input, cwd, riskHint, description)
-   - `perm.response` message (requestId, decision: "allow" | "deny", rememberForSession?: boolean)
+   - `ChatTurn` schema and types:
+     `id: string` (`msg_...`), `role: "user" | "assistant"`, `text?: string`, `toolEvents?: AgentStreamEvent[]`, `timestamp: number`, `status: "streaming" | "done" | "aborted" | "error"`.
+   - `chat.history.req` message (`projectCwd?: string`, `limit?: number`).
+   - `chat.history.resp` message (`currentCwd: string`, `turns: ChatTurn[]`).
+   - Register in `registry.ts`, `codec.ts`, `index.ts`.
 2. **Pure core interfaces (`packages/agent/src/core`)**:
-   - `IPermissionBridge`, `PermissionRequest`, `PermissionDecision` in `src/core/permission.ts`
-   - `IAuditLogger`, `AuditEntry` in `src/core/audit.ts`
-   - Zero Node builtins or I/O imports
-3. **Permission & Audit Adapters (`packages/agent/src/adapters`)**:
-   - `PermissionBridge` in `src/adapters/permission/bridge.ts` (manages pending requests, timeouts, session allowlist, auto-allow for safe reads)
-   - `FileAuditLogger` in `src/adapters/audit/file-audit.ts` (append-only JSONL log, written before execution)
-   - Wire permission interception into `LocalClaudeDriver` and `AgentDaemon`
-4. **Mobile Client & UI (`packages/mobile`)**:
-   - `onPermissionRequest`, `respondPermission` in `AgentClient`
-   - `PermissionCard.tsx` React Native component with allow/deny actions and risk badge
-   - Embedded into Terminal/Chat view
+   - `ITranscriptStore`, `TranscriptFilter` in `src/core/transcript.ts` (0 Node builtins or I/O imports).
+   - Manages ordered turns per project session key, truncation/size cap, and retrieval.
+3. **Transcript Store Adapter & Daemon Integration (`packages/agent`)**:
+   - `FileTranscriptStore` in `src/adapters/storage/file-transcript.ts`:
+     - Local JSON persistence under `~/.shellmind/transcripts/` (mode 0600).
+     - Caps history to last N turns (default 100) to prevent unbounded file growth.
+     - Isolate transcripts by project directory key.
+   - Wire into `AgentDaemon`:
+     - On `agent.prompt`: records user turn; streams events and records completed assistant turn.
+     - On `chat.history.req`: returns stored turns for the current project.
+     - On `project.set`: switches active project transcript context.
+4. **Mobile Tool Renderer Registry & Chat UI (`packages/mobile`)**:
+   - `ToolEventRenderer` registry in `packages/mobile/src/renderers/`:
+     - `Bash`: terminal command & output card.
+     - `Read` / `Write` / `Edit`: file modification card.
+     - `GlobTool` / `GrepTool`: search query card.
+     - `Default`: fallback generic renderer for arbitrary/unrecognized tools.
+   - `ChatScreen.tsx`:
+     - Project Picker dropdown (drives `project.list` and `project.set`).
+     - Live streaming chat timeline: user bubbles, assistant streaming text, tool renderer cards, in-flight `PermissionCard` embed.
+     - Input bar: prompt text field, Send button, Abort button (visible when busy).
+     - Reconnect resume: calls `requestChatHistory()` to populate transcript seamlessly without duplicates.
+   - Update `AgentClient` in `packages/mobile/src/client.ts` with `requestChatHistory` and `onChatHistory`.
 5. **Testing and Verification**:
-   - Protocol tests for risk classification, allowlist, and message schemas
-   - Bridge & AuditLogger unit tests (timeout, session remember, append-only file, idempotency)
-   - AgentDaemon live socket integration tests
-   - Mobile client integration tests
-   - Maestro flow specification (`.maestro/permission_flow.yaml`)
-   - Monorepo build, typecheck, lint, test, `check-architecture.sh`, `pnpm verify`
+   - Protocol tests for `chat.history` messages and schemas.
+   - Unit tests for `FileTranscriptStore` (turn appending, size cap, project isolation, corrupted file resilience).
+   - Integration tests in `claude-driver.test.ts` & `agent.test.ts` for chat history sync and reconnect resumption.
+   - Mobile tests for `AgentClient.requestChatHistory`, `ToolEventRenderer` registry, and `ChatScreen`.
+   - Maestro flow specification (`.maestro/chat_flow.yaml`).
+   - Full verification suite: `pnpm verify`.

+## Summary
+
+This PR implements **F009: Chat UI (streaming) + session continuity (reconnect resumes) + project picker**, completing **Phase 03 (AI — Claude Code bridge)**.
+
+### Changes Included:
+1. **Wire Protocol (`@shellmind/protocol`)**:
+   - `ChatTurn` schema & types (`id`, `role`, `text`, `toolEvents`, `timestamp`, `status`).
+   - `chat.history.req`: Client history query (`{ projectCwd?: string; limit?: number }`).
+   - `chat.history.resp`: Agent history response (`{ currentCwd: string; turns: ChatTurn[] }`).
+   - Registered in `KnownMessage` union, registry, and codec.
+2. **Pure Core Interfaces (`@shellmind/agent`)**:
+   - `ITranscriptStore`, `TranscriptFilter` in `src/core/transcript.ts` (0 Node builtins or I/O imports).
+   - Manages chronological turns, ID updates, size cap pruning, and project isolation.
+3. **Storage Adapter & Daemon Integration (`@shellmind/agent`)**:
+   - `FileTranscriptStore` in `src/adapters/storage/file-transcript.ts`:
+     - Local JSON persistence under `~/.shellmind/transcripts/` with file mode `0600` and dir mode `0700`.
+     - Bounded storage capped at max N turns (default 100).
+     - Isolated per project working directory path via sanitized slug + SHA-256 hash.
+     - Resilient error recovery: gracefully recovers with empty transcript on corrupt JSON files.
+   - `AgentDaemon`:
+     - Records user turns on `agent.prompt`.
+     - Accumulates assistant text deltas and tool events into completed assistant turn in transcript.
+     - Handles `chat.history.req` and replies with `chat.history.resp`.
+     - Automatically switches transcript context when `project.set` changes cwd.
+4. **Mobile Client, Tool Renderers & UI (`@shellmind/mobile`)**:
+   - `AgentClient` methods: `requestChatHistory(projectCwd?, limit?)` and `onChatHistory()`.
+   - Tool Renderer Registry (`packages/mobile/src/renderers/registry.ts`):
+     - `BashRenderer`: terminal execution card with command, running/success/error status pill, and collapsible output.
+     - `FileRenderer`: file modification card showing path, READ/WRITE/EDIT action badges, diffs, and results.
+     - `SearchRenderer`: search query card with pattern, directory, and matches preview.
+     - `DefaultRenderer`: safe fallback card for unrecognized tools.
+   - `ChatScreen.tsx`:
+     - Interactive project picker dropdown driving `project.list` and `project.set`.
+     - Live streaming feed showing user bubbles, assistant streaming text, tool cards, and embedded `PermissionCard`.
+     - Prompt input field with Send and Abort buttons.
+     - Seamless session continuity: requests transcript on connect/reconnect and deduplicates by turn ID.
+5. **E2E & Verification**:
+   - Maestro flow specification `.maestro/chat_flow.yaml` and trace in `.harness/evidence/F009/e2e-trace.txt`.
+   - 113/113 tests passing monorepo-wide (29 protocol, 52 agent, 32 mobile).
+   - Clean architecture verified with `dependency-cruiser` (70 modules, 209 dependencies cruised, 0 violations).
+   - Full suite passing (`pnpm verify`).
