"""cryptpad — BACKUP overlay (Phase 1e HC3): assertion-only + additive.

ops.pre_backup seeded "original" into cryptpad_data; the orchestrator performed the backup once
(generic tier asserted a snapshot artifact). This overlay ADDS: the seeded state is intact at backup
time. The backup→restore divergence is in ops.pre_restore."""
