Append-only history of person properties and cohort definitions, since the free tier overwrites the live person / prunes data. A new row is written only when the payload changes (hash compare), so the tables stay a compact change-timeline rather than a daily full copy. - `PosthogPersonSnapshot` (personId join key to PosthogEvent.personId, all distinct_ids, properties JSONB, propertiesHash). - `PosthogCohortSnapshot` (cohortId, name, count, filters, stateHash). - `listPersons` / `listCohorts` REST helpers (next-pagination) in posthog.ts. - `stableHash` (sorted-key JSON hash) in hash.ts for change detection. - `posthog-identity-archive` job wired @03:00 daily. Latest-hash lookup via one DISTINCT ON query, inserts only changed rows via createMany. Verified against prod: 242 persons → 242 snapshots on first run, 0 on immediate re-run (change detection). 0 cohorts currently → graceful no-op.
