Read and apply to the current task, citing rule IDs with one line of evidence as they fire:
- docs/guardrails/TEST.md — TE1–TE5
- docs/guardrails/DEBUG.md — "You are adding a regression test for the bug you just fixed" (revert-fail-restore proof)
- docs/guardrails/VERIFY.md — V2 (summary line quoted), V10 (expectation changes audited)
A portable CLAUDE.md + documentation set that makes Claude Opus / Sonnet operate as close to frontier (Fable) level as possible inside Claude Code: fewer logic errors, fewer introduced bugs, fewer wasted tokens.
