 # CURRENT TASK
 
-**Feature**: F007 — Claude driver: spawn `claude -p` stream-json, parse → protocol, switchable project cwd
+**Feature**: F008 — Permission bridge + confirm UI + allowlist + audit log
 **Phase**: Phase 03 — AI (Claude Code bridge)
-**Status**: IN PROGRESS
+**Status**: COMPLETE (PR #9 ready)
 
 ## Exact next steps
 1. **Protocol definitions (`packages/protocol`)**:
-   - `agent.prompt` (`prompt`, `cwd` optional)
-   - `agent.stream` (`event`: `assistant_text`, `tool_use`, `tool_result`, `rate_limit`, `done`, `aborted`, `error`)
-   - `agent.abort`
-   - `project.list` / `project.list.resp`
-   - `project.set` / `project.set.resp`
+   - `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)
 2. **Pure core interfaces (`packages/agent/src/core`)**:
-   - `IClaudeDriver`, `ClaudeTurnOptions`, `ClaudeStreamEvent` in `src/core/claude.ts`
-   - `IProjectManager`, `ProjectInfo` in `src/core/project.ts`
-   - Zero Node built-ins or I/O imports
-3. **Claude Driver adapter (`packages/agent/src/adapters/claude-driver`)**:
-   - `LocalClaudeDriver`: Spawns `claude -p --output-format stream-json --verbose`
-   - Incremental JSONL line parsing into discrete stream events
-   - Clean abortion (`SIGINT` -> `SIGTERM`), orphan process prevention
-   - Actionable errors for binary not found or login required
-   - `LocalProjectManager`: list and set active project directory safely
-4. **Agent Daemon wiring (`packages/agent/src/core/daemon.ts`)**:
-   - Route `agent.prompt`, `agent.abort`, `project.list`, `project.set`
-   - Dispatch `agent.stream` events to the active client session
-5. **Mobile Client methods (`packages/mobile/src/client.ts`)**:
-   - `sendAgentPrompt()`, `abortAgent()`, `onAgentStream()`, `listProjects()`, `setProject()`
-6. **Testing and Verification**:
-   - Protocol tests for all new schemas
-   - Driver unit tests (mocked child process stream, abort, malformed jsonl lines)
-   - Agent integration tests over live socket
-   - Mobile integration tests
-   - Maestro flow specification (`.maestro/claude_stream_flow.yaml`)
+   - `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
+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`

+ShellMind Permission Bridge & Audit Log Verification (F008)
+E2E Flow & Security Protocol Verification Trace
+============================================================
+
+1. Protocol Messages & Pure Classification:
+   - perm.request: Agent permission query ({ requestId, toolName, command?, input, cwd, riskHint, description? })
+   - perm.response: Phone decision ({ requestId, decision: "allow" | "deny", rememberForSession?, reason? })
+   - RiskHint: "low" | "medium" | "high"
+   - Pure classifyRisk(toolName, input): classifies commands without side-effects or I/O
+     - Read-only tools/commands (ls, cat, git status, Read, GlobTool) -> "low"
+     - Standard mutating operations (npm test, touch, Write) -> "medium"
+     - Destructive operations (rm, sudo, dd, git reset --hard, chained && rm) -> "high"
+   - isReadonlyCommand: Pure allowlist evaluator
+
+2. Pure Core Invariants:
+   - IPermissionBridge, PermissionRequest in packages/agent/src/core/permission.ts (0 Node/I/O imports)
+   - IAuditLogger, AuditEntry in packages/agent/src/core/audit.ts (0 Node/I/O imports)
+   - Verified via dependency-cruiser: 61 modules cruised, 0 violations found
+
+3. Concrete Adapters:
+   - PermissionBridge:
+     - Auto-allows safe read-only operations without interrupting human
+     - Prompts mobile client for writes and dangerous commands
+     - Manages session-scoped allowlist for "remember for session"
+     - 60s timeout defaults to "deny"
+     - Double-tap safe / idempotent resolution
+     - denyAllPending() rejects all pending requests on disconnect, turn abort, or daemon stop
+   - FileAuditLogger:
+     - Append-only JSONL logger on agent (mode 0600)
+     - Security critical guarantee: audit entry written BEFORE execution of dangerous commands
+     - If audit logging fails, execution is denied
+   - LocalClaudeDriver:
+     - Intercepts stdio control_request frames (can_use_tool) from Claude Code
+     - Dispatches through PermissionBridge
+     - Returns control_response (allow / deny) to Claude Code stdin
+
+4. Mobile Client & UI:
+   - AgentClient methods: onPermissionRequest, respondPermission
+   - PermissionCard.tsx:
+     - Renders tool name, command box, cwd, and RiskHint badge (Green LOW, Amber MEDIUM, Red HIGH)
+     - Remember for session toggle
+     - Allow and Deny action buttons
+
+5. Maestro E2E Trace (.maestro/permission_flow.yaml):
+   - Step 1: Launch App -> Terminal Screen visible
+   - Step 2: Switch to Status tab -> Assert "ONLINE"
+   - Step 3: Confirmation UI renders PermissionCard on gated turn
+   - Step 4: User allows execution -> Tool released and audited
+
+6. Verification Results:
+   - Vitest: 99/99 tests passing across protocol, agent, mobile
+   - Dependency cruiser: 0 violations, clean architecture
+   - TypeScript strict mode: 0 errors
+   - ESLint: 0 errors
