- Enforce 32-char minimum on OAUTH_STATE_SECRET at startup (config.py)
- Write DCR client registry with owner-only (0o600) permissions before atomic replace
- Flip policy.yaml default write action from allow → deny
- Add CLAUDE.md with architecture, commands, and AGENTS.md contract summary
- Add .pre-commit-config.yaml mirroring `make lint` checks
- Update .gitignore: add .venv, .claude, .mypy_cache, .ruff_cache, .coverage.*
- Extend docs: audit log rotation guidance, OAUTH_STATE_SECRET and DCR_STORAGE_PATH notes
- Tests: short-secret rejection, 32-char acceptance, POSIX permission check for DCR store
