  "hypothesis": "A scheduled SQLite backup chain can bound storage without deleting the latest recovery copy if deletion requires a durable acknowledgement of an independently restored archive.",
  "method": "Pinned encrypted transport to a dedicated forced-command account; bounded length-prefixed files with hashes, immutable archive IDs and release guards; disposable writable restore input in a network-isolated resource-limited container; integrity, foreign-key, migration, cryptographic checkpoint and restored-byte comparisons; durable acknowledgements before local retention. Test invalid transport identity, corrupt payload, traversal, wrong release, duplicate delivery and successive snapshot retention, then run the real scheduled-service success hook.",

  "result": "Four distinct production snapshots were independently restored successfully. Twelve guard/retention tests passed. A deliberately rejected SSH host identity caused no local deletion; normal retry succeeded. Corrupt bytes, traversal and wrong release were rejected without altering committed archives. Duplicate delivery returned the original receipt and timestamp. After successive acknowledged backups, exactly two new local snapshots remained; remote same-day retention also kept two. The daily service success hook executed transfer and restore successfully. Health returned ok with no issues and application container IDs/restart counts were unchanged. Audit also found a stale hardcoded verifier image absent from the new host; replacement with the already-guarded expected image restored the scheduled backup path.",
  "status": "SUCCESS",
  "interpretation": "Observed operational success, not evidence of long-term scheduler availability. Writable disposable restore input applies the previously inspected WAL-sidecar memory; stored archives remain protected. Legacy recovery snapshots were retained and count toward local preflight quota. Quota exhaustion or remote failure blocks further growth/deletion and is surfaced in operational health; it does not shut down the application. Release/image/schema pins must be reviewed on upgrades. External push notification is not configured. Ordinary memory feedback was unavailable due to missing feedback scope; this Research record documents actual use without creating a duplicate ordinary memory.",
