 | **R-1186** | Backup & restore | P3 | **The nightly off-site copy is skipped silently when another backup holds the flag, and the catch-up never re-runs it.** `offbox.go:981-996` returns nil with an INFO line on the nightly path; `withLeg` marks the leg ended anyway (`cmd/controller/main.go:1246`). The 05:30 proof and 06:00 integrity check take the same flag, so a backup time near them collides every night. Only the hub's 48 h `offsite_stale` notices. CONFIRMED in code.
