## Dependencies
- 01, 02, 03, 04 can be done in parallel (security foundation)
- 05, 06, 07, 08 can be done in parallel (performance foundation)
- 09, 10, 11, 12 can be done in parallel (observability)
- 13 depends on 17, 18, 19, 20 (tests must pass before CI)
- 14 depends on 13, 15, 16 (CI + infra + env)
- 21, 22, 23, 24 can be done in parallel (compliance)
- 25, 26, 27 can be done in parallel (SEO)
- 28, 29, 30 can be done in parallel (API stability)
- 31, 32 can be done in parallel (DB ops)
- All groups can proceed independently
