Health Check
Public health/readiness check; verifies upload/output dirs are writable.
Returns HTTP 503 when any CRITICAL local check fails (unwritable dirs) so
orchestrator readiness probes pull a degraded instance out of rotation.
The Anyscale probe is informational only and never affects the status
code — an external outage must not mark this process unhealthy. For pure
liveness (process/event-loop alive) use GET /livez.
Authorizations
Bearer authentication header of the form Bearer <token>, where <token> is your auth token.
Response
Successful Response
Health check response.
checks maps each probed resource (e.g. upload_dir) to "ok"
or an error string. Overall status is "ok" only when all checks
pass; otherwise "degraded".
commit is the git SHA of the deployed code (set via
RENDER_GIT_COMMIT on Render, or GIT_COMMIT elsewhere).
