PR #291 implements fail-closed subagent delegation gates, satisfying the acceptance criteria of issue #266. All targeted and full-suite test results are clean.
PR #336 successfully splits the monolithic LLM project workflow into task-specific modules. All targeted tests and validation checks passed.
PR #288 makes the sibling-worktree test hermetic using a TemporaryDirectory. This resolves location-dependent test failures on the master checkout. All targeted and full-suite test results are clean.
PR #287 has passed all targeted and full-suite validation gates, and has been successfully verified against target branch baseline test results.
PR #286 remains blocked by the test failure in tests/test_health.py: TestMCPHealth.test_route_task_session_blocks_during_merge. The test still mocks check_mid_merge instead of assess_infra_stop, and therefore fails when run against the current implementation. Please update the test to mock assess_infra_stop.
