- wau/mau trailing scans run hourly and on day finalization, not every tick
- exclusion lookup failures cached 30s so an st outage cannot amplify
- unverified relation filter dropped; player emptiness checked in js
- anonymous unauthenticated read failures no longer logged
- alerts and exclusions ensure supertokens init on cold pods
- pure rollup accumulators with tests; daily upserts keyed date/metric/dim
- alert checks with db-backed cooldown and push to admin players
- in-process scheduler started from health probes
- health endpoint checks pb + supertokens, stale-while-revalidate, always 200
- sse connection counter moved to emitter
- telemetry feature server fns: events/errors/groups/rollups/alerts/status
