# Codex Start Here

Read these files first, in this exact order:

1. `README.md`
2. `AGENTS.md`
3. `docs/18-ultra-prep/AUTONOMOUS_BUILD_CHARTER.md`
4. `docs/V1_SCOPE_FREEZE.md`
5. `docs/SERVICE_ARCHITECTURE.md`
6. `docs/REPOSITORY_CONVENTIONS.md`
7. `docs/API_CONTRACTS.md`
8. `docs/DATABASE_IMPLEMENTATION_PLAN.md`
9. `docs/18-ultra-prep/CRITICAL_PATH_TO_V1.md`
10. `docs/18-ultra-prep/BUILD_PASS_TEMPLATE.md`

Then execute the first incomplete pass from:

- `prompts/codex/M10_PASS_SEQUENCE.md`

Rules:
- Do not skip ahead.
- Do not start UI polish before backend contracts exist.
- Do not fake geospatial processing; return honest pending/unavailable states.
- Update TODO/checklists after every pass.
