Auth strategy clarified per service: - SQS: Gateway validates JWT (kmsvc code unverified, needs Phase 3) - MinIO: Native JWT/OIDC support (validates itself, Phase 3: load-test) - Temporal: Native JWT via jwtKeyProvider (Phase 3: configure) - Memory, IAM: Services validate JWTs (dumb pipe) SQS now requires Authorization header at gateway. Phase 3 will implement actual JWT signature validation against Authentik.
