## QA Verification Complete ✅ **Status:** VERIFIED - All tests pass, coverage improved to 93% ### Verification Results - ✅ All 876 tests pass (no failures) - ✅ 55 tests in sessions router pass - ✅ Coverage: 71% → 93% (+22 points) - ✅ All requirements met ### Tests Added **22 new tests** across 3 test classes: - TestResumeSession (8 tests) - TestContinueSession (7 tests) - TestSendMessage (7 tests) ### Requirements Verified 1. **POST /resume**: Success, 404, 409, validation ✅ 2. **POST /continue**: Success, 404, 409, validation ✅ 3. **POST /messages**: Success, 404, 409, 422, 500 ✅ ### Code Quality - Comprehensive error case testing - Proper async/await patterns - Good use of mocking and fixtures - Clear, descriptive test names - No issues found **Detailed report:** /tmp/qa-CLIAPI-48.md

## Implementation Complete Added comprehensive router tests for POST /resume, /continue, and /messages endpoints. ### Changes Made - **tests/unit/test_sessions_router.py**: Added 3 new test classes with 22 total test cases: - `TestResumeSession`: 8 tests covering success, fork option, 404/409 errors, validation - `TestContinueSession`: 7 tests covering success, 404/409 errors, empty body handling - `TestSendMessage`: 7 tests covering success, 404/409/500 errors, validation ### Coverage Results - Sessions router coverage improved from 71% to **93%** ### Tests Added 1. **Resume Session** (`/sessions/{id}/resume`): - Success cases (basic, fork, failed/cancelled sessions) - 404 when session not found - 409 when session not completed (running, waiting_permission) - 422 when missing required prompt 2. **Continue Session** (`/sessions/{id}/continue`): - Success cases (basic, with empty body, failed/cancelled sessions) - 404 when session not found - 409 when session not in continuable state 3. **Send Message** (`/sessions/{id}/messages`): - Success case with running session accepting input - 404 when session not found - 409 when session not running - 409 when session doesn't accept input - 422 when missing content - 500 when write fails - Success when session waiting_permission (allowed state) ### Verification - All 55 tests in test_sessions_router.py pass - Full unit test suite passes (876 tests)

## Feature Triage Complete **Status:** PARTIALLY IMPLEMENTED (endpoints exist, tests missing) **Summary:** All three endpoints (POST /resume, /continue, /messages) are fully implemented. Only router-level tests are missing. Service-layer tests already exist. **Implementation Location:** `tests/unit/test_sessions_router.py` - add 3 new test classes (~20 tests) **Complexity:** low - straightforward pattern-following **Coverage Impact:** Will improve routers/sessions.py from 71% to ~95%+ See attached triage report for full details.
