"""Integration smoke test for the Python SDK against a running Armeria gRPC server.

The SDK is generated-only: there is no hand-written client wrapper. This script
talks to the server exactly the way the portal and airavata.experiments do —
raw protoc-generated stubs over an airavata.auth ``authenticated_channel``.

Prerequisites: server running on localhost:9090 (e.g. via ``tilt up``).

Usage:
    python3 scripts/test_python_sdk.py [--host localhost] [--port 9090] [--token <jwt>]
