"""custom-html — RESTORE overlay (Phase 1e HC3): data-integrity, assertion-only + additive.

The orchestrator ran `ops.pre_restore` (mutated the marker to "mutated", diverging from the backed-up
"original"), then performed the restore ONCE. The generic restore tier already asserted healthy +
serving; this overlay ADDS the recipe-specific check: the volume data returned to the pre-mutation
(backed-up) "original". Reads via exec_in_app (volume-direct), robust to the post-restore serving
race."""
