# Ingest historical exports

Poll the intended export manifest, download only unseen Parquet objects, validate schema version and checksum, load partitions idempotently, and retain revision metadata so later corrections can be reconciled.

## Cursor rule
Advance a durable cursor only after downstream storage succeeds. Treat a gap, correction, or finality change as a reason to backfill and reconcile.
