# QA Verification Report: CLIAPI-18 **Issue:** Permission detection & manager **Status:** ✅ VERIFIED **Date:** 2026-01-03 **QA Engineer:** Claude Code QA Agent **Branch:** CLIAPI-1 (commit: 9a4aa6a) --- ## Executive Summary The implementation of CLIAPI-18 has been **VERIFIED** as complete and working correctly. All requirements have been met, all tests pass, and the code quality is high. - **407 total tests passed** (including 28 new permission manager tests) - **0 test failures** - **All QA criteria met** - **Code follows project standards** - **No bugs or issues detected** --- ## QA Criteria Verification ### ✅ 1. Permission requests detected in output stream **Evidence:** - `PermissionManager.detect_permission_request()` method implemented (permission_manager.py:82-152) - Parses JSONL messages with `type: "permission_request"` - Extracts all required fields: id, session_id, tool_name, tool_input - Handles optional fields: description, risk_level, status - Comprehensive validation with logging **Tests:** - `test_detect_permission_request` - validates full detection - `test_detect_non_permission_message` - validates type filtering - `test_detect_missing_message_field` - validates message structure - `test_detect_missing_required_fields` - validates field requirements - `test_detect_minimal_permission_request` - validates minimal valid case - `test_detect_invalid_status` - validates status enum handling - `test_detect_invalid_risk_level` - validates risk level enum handling **Verification:** ✅ PASS --- ### ✅ 2. Permission objects have unique IDs **Evidence:** - `PermissionManager.generate_permission_id()` method implemented (permission_manager.py:328-334) - Uses UUID v4 with `perm-` prefix and 12-char hex suffix - Format: `perm-{uuid.uuid4().hex[:12]}` - Cryptographically strong uniqueness guarantee **Tests:** - `test_generate_permission_id` - validates format and generation - `test_generate_unique_ids` - validates 100 generated IDs are unique **Verification:** ✅ PASS --- ### ✅ 3. Session status changes to waiting_permission **Evidence:** - SessionManager integration in session_manager.py:449-456 - When `type: "permission_request"` message detected, sets `state.status = SessionStatus.WAITING_PERMISSION` - Properly integrated in `_read_output()` async stream processor - Status returns to RUNNING after permission_response (lines 460-463) **Code:** ```python # Check for permission request and register with manager if msg.get("type") == "permission_request": state.status = SessionStatus.WAITING_PERMISSION perm_request = self._permission_manager.detect_permission_request(msg) if perm_request: state.current_permission = perm_request await self._permission_manager.add_pending( state.session_id, perm_request ) # Check for permission response (clears current permission) if msg.get("type") == "permission_response": state.current_permission = None # If session was waiting for permission, return to running if state.status == SessionStatus.WAITING_PERMISSION: state.status = SessionStatus.RUNNING ``` **Verification:** ✅ PASS --- ### ✅ 4. History tracks approved/denied decisions **Evidence:** - `PermissionManager.resolve()` method implemented (permission_manager.py:225-282) - Creates `PermissionHistory` objects on approval/denial - Stores decision, timestamp, reason, tool_name, permission_id, session_id - Maintains history per session in chronological order - `get_history()` returns newest-first with optional limit **Tests:** - `test_resolve_approved` - validates approval creates history - `test_resolve_denied` - validates denial creates history - `test_history_after_resolve` - validates history contains decision - `test_history_ordering` - validates newest-first ordering - `test_history_limit` - validates limit parameter **Data Structure:** ```python @dataclass class PermissionHistory: permission_id: str session_id: str tool_name: str decision: str # "approved" or "denied" decided_at: datetime reason: str | None = None ``` **Verification:** ✅ PASS --- ### ✅ 5. Works with permission request fixture **Evidence:** - Test fixtures defined in `tests/unit/test_permission_manager.py` - `sample_permission_message` fixture provides realistic JSONL message - Tests validate parsing of fixture data: - permission_id: "perm-001" - session_id: "session-123" - tool_name: "Bash" - tool_input: `{"command": "rm -rf node_modules"}` - description: "Delete node_modules directory" - risk_level: "medium" **Tests using fixture:** - All 7 detection tests use the sample fixture - Integration tests validate end-to-end flow **Verification:** ✅ PASS --- ## Implementation Review ### 1. Models (models/session.py) **Added:** - `PermissionStatus` enum (pending, approved, denied) - `RiskLevel` enum (low, medium, high) - `PermissionRequest` model with 12 fields - `PermissionDecision` model with 4 fields **Quality:** - Proper Pydantic models with Field descriptions - Timezone-aware datetime defaults using UTC - Optional fields properly typed with `| None` - Comprehensive field documentation **Code Location:** session.py:288-366 --- ### 2. PermissionManager Service (services/permission_manager.py) **Methods Implemented:** 1. `detect_permission_request()` - Parse JSONL messages 2. `add_pending()` - Store pending permission 3. `get_pending()` - Retrieve specific pending permission 4. `list_pending()` - List all pending for session 5. `resolve()` - Approve/deny and move to history 6. `get_history()` - Get decision history 7. `cleanup_session()` - Clear session state 8. `generate_permission_id()` - Generate unique IDs **Architecture:** - Thread-safe with asyncio locks - Per-session storage with `SessionPermissions` dataclass - Global singleton pattern with `get_permission_manager()` - Comprehensive structured logging - Proper error handling with custom exceptions **Code Location:** permission_manager.py:1-360 (360 lines) --- ### 3. SessionManager Integration (services/session_manager.py) **Changes:** 1. Added `permission_manager` parameter to `__init__()` 2. Added `current_permission` field to `SessionState` 3. Integrated detection in `_read_output()` stream processor 4. Added `get_current_permission()` method 5. Added `permission_manager` property 6.

## Feature Triage Complete **Status:** PARTIALLY IMPLEMENTED **Summary:** Core permission detection exists in SessionManager (line 412) but PermissionManager service is empty. Models for permission requests/decisions are not defined. API endpoints for permission approval are not implemented. ### Already Implemented - Session status change to `waiting_permission` on detection - `SessionConfig.interactive_permissions` field - `SessionResult.permission_denials` field - Test fixtures and integration tests ### Missing (scope of this ticket) 1. `PermissionRequest` / `PermissionDecision` Pydantic models 2. `PermissionManager` service implementation 3. Permission storage per session 4. Approval/denial history tracking 5. Integration with SessionManager ### Dependencies - CLIAPI-12 (streaming utilities) - DONE **Complexity:** Medium **Files to modify:** 4 (models/session.py, services/permission_manager.py, services/session_manager.py, tests/unit/test_permission_manager.py) See attached triage report for full implementation details.
