Ready
Readiness probe — public, unauthenticated.
Returns 200 only when this API process can reach its own datastores:
Postgres and both Redis DBs. Returns 503 with the failing subsystem
names ({"status": "not_ready", "failed": [...]}). Subsystem-level
*detail* (hostnames, exceptions) is logged via structlog and never
returned in the body.
Deliberately does **not** probe Celery workers. That leg was a Celery
`inspect().ping()` — a broadcast RPC over the broker with a 2.5 s
budget — and it flapped: on 2026-08-20 it produced ten 503s in 19
minutes, interleaved with 200s, while worker CPU sat at 0.2%. Worker
liveness is covered twice over by signals that ask the workers
directly: each worker service exposes its own /ready sidecar (broker
reachability plus a 90 s Celery heartbeat, src/workers/healthcheck.py),
and the `synthetic-probe` beat task runs every minute behind a Sentry
cron monitor. `/health/detailed` still reports worker status for
on-demand diagnosis.
Intended for Betterstack / external monitoring. **Do not** wire this
as Railway's container healthcheck — a 30 s Redis blip would restart
the API. See docs/deployment/external-monitoring.md.
