"""lasuite-docs — RESTORE overlay (Phase 1d, DG4): data-integrity, extends the generic restore.

Runs after the backup overlay (test_backup.py) on the SAME shared deployment, which left the postgres
marker table dropped after dumping it. This restores the snapshot via the shared op helper
(`generic.do_restore`, which also asserts the app is healthy + serving afterwards; the recipe's
restore.post-hook reloads the dump), then asserts the restored DB matches the pre-mutation "original"
— the app-specific data integrity the generic restore cannot check. Reads via `psql` in the `db`
service. Assertion-only (no deploy/teardown)."""
