feat(server): daily retention sweeper (ADR-0004)#65
Merged
Conversation
A BullMQ repeatable job in the worker (daily 03:30 UTC) deletes identities whose last_seen is older than their project's retention_days; snapshots, drifts, risk assessments, cluster merges, and account links cascade. Projects with a null retention_days keep data indefinitely. - pipeline/retention.ts: sweepRetention(sql) — idempotent, returns per-run counts. - worker.ts: schedules the repeatable job (idempotent add) + a dedicated worker on a separate `retention` queue; both close cleanly on shutdown. - retention.integration.test.ts: old identity swept, recent kept, null-retention project untouched.

Fourth PR of the Consent & Data-Lifecycle workstream (ADR-0004).
What
A daily BullMQ repeatable job in the worker deletes data past each project's retention window:
pipeline/retention.ts—sweepRetention(sql): for every project with a positiveretention_days,DELETE FROM identities WHERE last_seen < now() - retention_days(snapshots/drifts/risk/links cascade). Projects with a nullretention_dayskeep data forever and are skipped. Idempotent; returns per-run counts.worker.ts— schedules the repeatable job (daily 03:30 UTC; BullMQ dedupes by repeat key so re-adding on every boot is safe) on a dedicatedretentionqueue, plus a worker to process it. Both close cleanly on shutdown.Tests
retention.integration.test.ts): a 60-day-old identity is swept, a 1-day-old one is kept, and an identity under a null-retention project is untouched. Full server suite: 128 passing locally.
