Time to restore (TTR)

Definition

How long it takes, once a harm is confirmed, to restore the person to their prior state. Low TTR is a signal of reversibility.

Targets & breach behavior. Measurement window: weekly p95; monthly median. Target / floor / ceiling: target ≤ 24h, floor ≤ 72h, ceiling 7d. Owner: traceable ownership (required). Breach action: activate rollback lanes, switch to staffed remediation, or trigger safe pause with escalation. Public surface: receipt + time transparency with restoration ETA and decision artifact.
