## Fix Completed **Problem Found:** The `_read_output()` method in `session_manager.py` (lines 862-873) only handled 'result' and 'user' message types. It never detected 'permission_request' messages, so: - Session status never transitioned to WAITING_PERMISSION - send_permission_response() failed because status check failed - Permission approval flow was completely broken **Changes Made:** 1. Added import for `get_permission_manager` in session_manager.py:18 2. Added handling for `permission_request` message type in `_read_output()` (session_manager.py:876-894): - Extract tool info from message (supporting both top-level and nested "message" field formats) - Call `detect_permission_request()` to create PermissionRequest - Call `add_pending()` to add to PermissionManager - Set session status to `WAITING_PERMISSION` **Tests Added:** - `test_permission_request_sets_waiting_status`: Verifies status transitions to WAITING_PERMISSION - `test_permission_request_adds_to_pending`: Verifies permission is added to PermissionManager pending list **Verification:** - All 847 unit tests pass - Permission-related tests (28 tests) all pass - No new type errors introduced - Import ordering fixed to satisfy linter Commit: 2c4585b

## Bug Triage Complete **Reproduction:** CONFIRMED **Summary:** The `_read_output()` method in `session_manager.py` (lines 862-873) only handles 'result' and 'user' message types. It never detects 'permission_request' messages, so the session status never transitions to `WAITING_PERMISSION`, causing `send_permission_response()` to fail. **Root Cause:** Missing handling for `permission_request` message type in the output reader. The `PermissionManager.detect_permission_request()` method exists and is tested but is never called from the critical path. **TDD Approach:** 1. Write failing test that verifies status transitions to WAITING_PERMISSION on permission_request 2. Add handling in `_read_output()` to call `detect_permission_request()` and set status 3. Verify end-to-end permission approval flow works **Complexity:** Low - fix is straightforward, infrastructure exists See attached triage report for full details.
