- AGENTS.md only indexes the existing documents (ARCHITECTURE, DESIGN index, SIM / META / DATA / I18N, the kits README)
and their hard rules (official first + [ASSUMED], sim determinism and detmath, golden results, generated data, no game
art, t() strings, docs with the code, commit / PR conventions, verification commands); CONTRIBUTING.md stays the full
text. CLAUDE.md is one line pointing to it.
- Tests: docs-paths, docs-consistency.
