- Tests pass
- Intercept `execute_transforms`, `histogram`, and `composite` calls in the SDK. - Redirect these calls to a custom, self-hosted gRPC service defined by `IMAGES_SERVICE_ENDPOINT`. - Implement secure service-to-service authentication using OIDC tokens (via `google.auth` and `grpc.access_token_call_credentials`). - Support native Google Cloud Storage (GCS) integration by passing raw `/gs/` paths to the external service, bypassing legacy BlobKey encoding. - Implement fallback logic for legacy BlobKeys: automatically fetch blob content locally and send raw bytes to the external service when a direct reference cannot be resolved. - Increase gRPC max receive message size to 32MB to support high-resolution image processing. - Refactor internal logic to share authentication and channel creation code across all API methods.
