21 passed / 0 failed across assistant::, plus assistant_methods_require_session run explicitly. Both windows had non-defect root causes: window 19 was lane staleness (missing 0de67ca6's PortMapping test-constructor fix, which made the whole crate's test build fail), and window 16's repeated kills were the orchestrator's own too-short timeout sending SIGTERM on a cold build, which I had wrongly attributed to memory contention.
