Reject null telemetry timestamps before DateTime conversion.
convertDataToJsTypes() applies new Date(value) to DateTime columns without a null check. If Cloudflare returns null for first_at or last_at, it becomes the Unix epoch and passes telemetryRow. For an app with a null created_at, the lower-bound check also uses the Unix epoch. The refresh can then persist a false 1970 milestone and delete the lease. Require a non-empty timestamp string or a valid Date before conversion.

Summary
The existing SQL cron scheduler now calls
public.enqueue_app_onboarding_refreshes()every ten minutes. That function leases up to 3,000 due apps and atomically enqueues batches of at most twenty intocron_onboarding_refresh_apps. The existing queue dispatcher invokes only the backend app-batch consumer every minute, with a cap of fifteen messages (300 apps) per dispatch. There is no backend producer endpoint or producer queue.The consumer reads production
set-derived install activity and device sources directly from Cloudflare Analytics Engine and merges the resulting feature progress into the current app row through Drizzle. It preserves historic milestones and concurrent checklist updates. The old scheduled SQL batch function is dropped; the single-app Verify RPC remains.Why
The previous hourly refresh depended on delayed Supabase telemetry rollups. Direct Cloudflare reads can show activity sooner, while the existing SQL scheduler and a bounded consumer queue spread database and provider work over time. This changes neither checklist assignment nor email delivery. All apps remain eligible; a full sweep can take longer than ten minutes when more than 3,000 apps are due. Analytics Engine's three-month retention and sampling remain limits.
Validation
The producer is internal and service-role-only. Workers lock at most twenty apps per message. No new function runs in public RLS, views, or plugin traffic, and no plugin endpoint reads the primary database.
