See AGENTS.md for the full picture.
Key rules:
- This repository is documentation only — no build, no tests, no releases.
- Japanese (
docs/ja/) is the authoring source; keepdocs/en/in sync in the same commit. Keep both README catalogs in sync too. - Every entry follows symptom → why → how to apply; origins are cited in generalized form (project + rough date, no personal names).
- Sanitization gate: never commit environment-specific values — no GCP project IDs, service-account emails, tokens, hostnames, absolute local paths, or personal names (ADR-015 §5).
- Small, typed commits (
docs:,chore:).
