Operational test
Evidence appears in documentation, interface cues, or governance artifacts that reflect time-to-halt (tth).
Use this test to validate operational readiness.
Pair this test with the minimum evidence criteria to capture both qualitative and quantitative signals.
- Evidence artifact: Artifact documenting how Time-to-Halt (TTH) is expected, enforced, or governed.
- Behavior signal: Observed behavior showing Time-to-Halt (TTH) in practice during real use or drills.
- Metric signal: Metric tracked to monitor Time-to-Halt (TTH) performance over time.
Seconds between a harmful process beginning and the system stopping it—an essential complement to stoppability . Targets & breach behavior. Measurement window: weekly p95; monthly p99. Target / floor / ceiling: target ≤ 30s (automated) / ≤ 5 min (human), floor 15 min, ceiling 60 min. Owner: Traceable Ownership (must have). Breach action: trigger ethical circuit breakers , safe pause , or rollback lane activation with escalation. Public surface: receipt + time transparency showing halt status and decision artifact .
