hermes-agent/tests/gateway/test_stop_thread_sibling.py

"""Regression tests: /stop can interrupt a sibling participant's run in a
per-user thread.

When ``thread_sessions_per_user=True``, each participant in a thread gets an
isolated session key (``...:{thread_id}:{user_id}``).  A run another user
started lives under a different key, so the caller's own ``/stop`` used to find
nothing and reply "no active task to stop".  Authorized users should be able to
stop any run in the same thread.
