Trace-grounded CLAUDE.md adherence: rank the prose rules your agents demonstrably ignore from your run history, then scaffold a deterministic hook for the violated convertible subset. Observer-only; keeps safety rules as prose; never writes settings.json.
Trips at iteration 2 on duplicate-work, ping-pong/livelock, deadlock, and non-termination across cast.db and OpenTelemetry GenAI handoff spans. Read-only observer, never a gate; off by default.
Verifies a subagent's Status: DONE against the real git delta and blocks DONEs whose files never landed. Zero-LLM, fail-open, off by default.
