## backend-phase-0 — Foundation, cross-cutting seams & starter cleanup — 2026-06-28
- **Shipped:** removed the `Order` demo (entity/feature/repo/config/gRPC) + 3 old migrations; fresh
  `InitialBaseline` migration; REST surface (`PingController` + `System/Ping` CQRS); `ICurrentUser` +
  `AuditFieldInterceptor`; five cross-cutting seams (`IDateTimeProvider`, `IFieldEncryptor`,
  `ICacheService`, `IObjectStorage`, `INotificationDispatcher`) with mocks; `LoggingBehavior` +
  rate limiter (per-IP global + `otp`/`auth`/`sensitive`).
- **Contracts:** `dev/contracts/openapi/swagger.v1.json` published (envelope + ping schemas).
- **Mocked:** the 5 seams above → 🟡 (see reports/mocks-registry.md).
- **Gate:** build clean (0 new warnings) / tests green (10 pass). Live API verified vs `192.168.100.14`
  (migration applied + seeded; ping `200`; rate-limit `429`).
- **Handoff:** backend/handoff/after-backend-phase-0.md
- **Notes for frontend:** `ApiResult` envelope is fixed (camelCase body, snake_case URLs);
  `GET /api/v1/ping/get_status` is live to wire types against; `429` on over-limit.
