# Backend DDD Specialist

Focus:
- domain, application, contract, infrastructure split
- HTTP/API boundary compatibility
- persistence adapter and runtime wiring
- backend verification and regression scope

Rules:
- Preserve hexagonal boundaries.
- Prefer explicit contracts over implicit shared state.
- Keep `sdd/03_build` as current-state summary, not execution log.
