+# TODO
+
+## High priority
+
+- [ ] Handle client network failures in `cli/src/whisper_remote_cli/main.py`.
+  Right now connection errors and timeouts from `httpx` will dump a Python traceback instead of a clean CLI error.
+
+- [ ] Add a backend subprocess timeout in `backend/src/whisper_remote_backend/server.py`.
+  A stuck `whisper` process can hold the request open forever and tie up the API worker.
+
+- [ ] Add an end-to-end smoke test path against a real `whisper` binary.
+  Current tests only mock subprocess behavior, so we still have not verified the actual CLI wrapper contract on a live backend.
+
+## Medium priority
+
+- [ ] Return structured JSON errors from the backend and make the CLI surface them nicely.
+  Right now the CLI just prints the raw response body, which will be awkward for FastAPI's default JSON error payloads.
+
+- [ ] Add test coverage for cleanup and artifact-writing behavior.
+  Missing cases include ensuring temp files are removed on failure and verifying `--to-file` writes the expected local artifact content.
+
+- [ ] Document Windows-first setup in the root README.
+  The examples currently use `export`, but this repo is being built on Windows and should show PowerShell equivalents for `WHISPER_REMOTE`.
+
+## Nice to have
+
+- [ ] Support configurable host and port for `whisper-remote-server`.
+  The backend entrypoint currently hardcodes `0.0.0.0:8000`.
+
+- [ ] Add optional request authentication.
+  v1 intentionally has no auth, but even a shared bearer token mode would make remote exposure less risky.
