 ## Running Tests Locally
 
 To run these tests on your machine, you need to have the emulator running in one terminal session and execute the tests in another.

-## Known Limitations
-
-The Firebase Storage Emulator is a high-fidelity implementation of the Cloud Storage for Firebase API, which is a subset of the full Google Cloud Storage JSON API. Consequently:
-
-- Some advanced GCS features (e.g., Object Retention/Lock, certain IAM configurations, or specific query parameters) may return a `NotImplementedException` (HTTP 501) or `BadRequestException`.
-- Always verify critical production logic against a live GCS project using the recorded API tests in the `test/` directory.
