# Health Check

`GET /health_check`

Liveness health check.

When the ``ADVANCED_HEALTH_CHECK`` environment variable is ``"true"``, performs a
full connectivity check against Redis and PostgreSQL and returns a composite status
object.  Otherwise returns a minimal ``{"status": "ok"}`` ping response immediately,
keeping the endpoint lightweight for load-balancer probes.

Returns:
    JSONResponse: 200 when all checked services are healthy, 500 otherwise.

## Response `200`

Successful Response
