Full details: Docstring CoverageExplanation Docstring coverage is 15.79% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 19 functions across 9 files. (2 skipped: 2 unsupported.) Full details: Description checkExplanation The description is detailed but materially contradicts the implementation and objectives. It describes 25-app batches, 500-app limits, legacy SQL telemetry, and no lease table or Cloudflare credentials, while the changes add lease jobs, batch tokens, 20-app messages, a 3,000-app cap, and Cloudflare Analytics Engine reads. Resolution Replace the description with an accurate summary of the backend producer and consumer, lease table and batch-token behavior, 20-app batching, 3,000-app cap, 15-message-per-minute processing, Cloudflare Analytics Engine telemetry, transaction and timeout behavior, removed scheduled RPC, documentation updates, and the actual tests and validation results. ✨ Finishing Touches 💡 1📝 Generate docstrings 💡

non-empty timestamp string or a valid Date. Ensure first_at, last_at, and
created_at cannot become the Unix epoch and allow telemetry validation to fail

The hourly SQL batch refreshed onboarding features for every app, while the backend queue implementation added a separate lease table and changed the evidence source to Cloudflare Analytics Engine. This PR keeps the old PostgreSQL feature calculations and moves only the bounded execution into the backend.
The existing SQL scheduler now runs a producer every 10 minutes. It selects up to 500 due apps whose organization is paying, in trial, or has an unexpired credit grant with remaining credits. The producer atomically writes
apps.onboarding.queued_refresh_atand enqueues groups of at most 25 app IDs. The existing minute queue dispatcher handles up to four messages (100 apps) per run. Messages older than 30 minutes can be queued again if no refresh has completed.The backend consumer reads
devices,app_versions,daily_version, andbuild_requestsusing the old predicates in one Drizzle transaction, then locks the selected apps and merges only the three feature entries plusrefreshed_atinto the current JSON. Replayed or overtaken messages skip apps already refreshed after their enqueue time. The old scheduled batch RPC is removed; the single-app verification RPC remains. No lease table, batch token, or Cloudflare analytics credential is needed.Validation: frontend/backend lint, typecheck, production build, and the full CLI check passed; 3,205 unit tests passed with
TZ=UTC, and 294 Tinbase database tests passed. A throwaway PostgreSQL 17 instance applied the migration and passed synthetic assertions for billing eligibility, 25-app grouping, 30-minute recovery, and the 500-app cap. The actual consumer transaction passed milestone, JSON-preservation, and replay assertions there. AnEXPLAIN (ANALYZE, BUFFERS)selection of 500 from 20,000 synthetic apps used the queued-refresh index and completed in 0.58 ms. The full Supabase/Docker integration run was unavailable locally because the Docker PostgreSQL port did not respond.
