 - Wired the OTP adapters into runtime composition and generation, delivery, verification, and deletion paths while retaining compatibility fallback; full Auth tests pass in `c951875`.
 - Wired the OTP template repository port and adapter into runtime composition and TFA processing; legacy fallback remains for compatibility and full Auth tests pass in `741415b`.
 - Added thin Auth and internal Auth gRPC registration adapters and routed server registration through them; full Auth tests pass in `b56d54c`. A004 is complete; remaining legacy fallback removal is tracked under A008.
-- A004 remains in progress: template lookup, delivery, verification, and thin gRPC adapter extraction still use the legacy use-case/repository composition.

+- Extracted HTTP bearer-token normalization into `application/auth` and kept JWT verification/error mapping behavior unchanged; focused and full Auth tests pass in `1d72faa`.
+- A005 remains in progress: JWT validation, session checks, refresh-token flow, and broader authentication orchestration still need application ports and adapters.

 | A002 | `DONE` | Introduce auth domain entities, value objects, errors, and repository ports. | Added pure Auth entities/value objects, domain errors, and inward-facing repository/cache ports with no gRPC, GORM, Redis, or framework imports; committed as `32f182b`/`d292822`. |
