# Health Check

`GET /health`

Return a lightweight service health and active-session snapshot.

Args:
    None.

Returns:
    A healthy status string and the current number of registered sessions.

Raises:
    None.

Behavior:
    The endpoint reads only the in-memory registry and does not expire sessions,
    await solver work, or probe Z3. It therefore confirms process responsiveness
    rather than the satisfiability or completion of individual requests.
