All services are online

Whether the learner platform API is reachable and answering requests. This is a liveness check only — it stays green even if the services behind the API are failing, so read it alongside Logins & Queue Admission.

Whether the managed API can reach Valkey and accept new work into its queue. Green means sign-ins can pass the Valkey-backed limiter and jobs can be enqueued; it does not prove that workers complete them. Red means sign-ins and/or new queued work are failing even though the API process may still be up.
