    "First real observation for this resource. It went live mid-period: bucket created 2026-08-14T16:21:56Z, first backup 2026-08-14T18:14:21Z, so 2026-08 covers roughly four hours of operation, not a month.",
    "Backup success is 1 of 1 completed backups, not a month of scheduled runs.",
    "restore_rto_minutes is the full-restore wall time of 65 seconds; PITR measured the same 65 seconds on the second attempt after the recovery target was corrected.",
    "Observed RPO: archive_timeout is 5 minutes and a WAL segment archived about 2 seconds after pg_switch_wal, so the measured RPO is well inside the 5-minute requirement — but on four hours of evidence.",
    "Comparing this period against the 12-month decision forecast will show a very large negative stored_gb error. That is a model artifact, not underuse: the forecast assumes 30 days of retained base backups and WAL at steady state, and this period holds one backup."
