"""cryptpad — 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
cryptpad_data marker mutated to "mutated" after backing up "original". This restores the snapshot via
the shared op helper (`generic.do_restore`, which also asserts the app is healthy + serving
afterwards), then asserts the volume data returned to the pre-mutation "original" — the app-specific
data integrity the generic restore cannot check. Reads the marker via `exec_in_app` (data isn't
HTTP-served). Assertion-only (no deploy/teardown)."""
