[QA PASSED] Verified all requirements for CDEV-11: ✅ POST /api/containers/{name}/start endpoint exists (containers.py:199-241) ✅ POST /api/containers/{name}/stop endpoint exists (containers.py:244-288) ✅ DB status updated on start: container.status='running', started_at set ✅ DB status updated on stop: container.status='stopped', stopped_at set ✅ 3 new tests verify state transitions All 303 tests pass. No security issues. Implementation complete. Full report: /tmp/qa-CDEV-11.md

Verified implementation of container start/stop endpoints: ## Endpoints Implemented (already in codebase) - POST /api/containers/{name}/start (containers.py:199-241) - POST /api/containers/{name}/stop (containers.py:244-288) ## DB Status Updates (already in codebase) - process_start_container (job_processor.py:487-528): Updates container.status='running' and sets started_at - process_stop_container (job_processor.py:531-574): Updates container.status='stopped' and sets stopped_at ## Tests Added Added 3 new tests to verify DB status updates on state change: - test_start_container_success: Verifies job completes and container.status becomes 'running' with started_at set - test_stop_container_success: Verifies job completes and container.status becomes 'stopped' with stopped_at set - test_stop_container_with_force: Verifies force=true is passed to Incus ## Test Results - All 321 tests pass - Coverage: 76.74% (exceeds 74% requirement)
