- CLAUDE.md: new "Collaboration" section (plan-first, options-with-marked-
optimal-and-why, mockups for design decisions, challenge unsound requests,
visual UAT before done, terse otherwise).
- CLAUDE.md: clarify release is user-owned in timing, agent-run in execution.
- CLAUDE.md + docs/development.md: document the ruff format --check gate step
(already enforced in .gitea/workflows/check.yml, was missing from the docs).
- CLAUDE.md: refresh the stale footer to point at the now-existing
docs/development.md and backend/app/README.md.
The codebase is fully AI-authored and developed across many agent sessions; the
canonical conventions have lived only in a private memory store, which the
2026-08-17 review flagged as a real gap (unwritten rules → asymmetric fixes and
comment-vs-code drift, e.g. the cancelled/canceled literal bug).
Add a short, auto-loaded rules-of-the-road: the local gate (never merge/ship
red, no --skip), the trunk workflow and no-AI-co-author commit rule, the
one-way architecture shape, a canonical-pattern table (the review's §6
consistency choices), and the house rules learned from real bugs. Kept
deliberately thin; slims to a pointer once docs/development.md lands.
