Fail-Safe Mode — Operational test: Evidence appears in documentation, interface cues, or governance artifacts that reflect fail-safe mode.

Operational test "Evidence appears in documentation, interface cues, or governance artifacts that reflect fail-safe mode." for Fail-Safe Mode in the System states & architectures glossary category.

Pair this test with the minimum evidence criteria to capture both qualitative and quantitative signals.

  • Evidence artifact: Artifact documenting how Fail-Safe Mode is expected, enforced, or governed.
  • Behavior signal: Observed behavior showing Fail-Safe Mode in practice during real use or drills.
  • Metric signal: Metric tracked to monitor Fail-Safe Mode performance over time.

Context

How this test fits the glossary entry

Category: System states & architectures

The system defaults to the safest possible behavior when uncertain, prioritizing stoppability over throughput. In Ethotechnic practice, fail-safe mode is not a generic error page: it is a predesigned degraded state with bounded actions, clear status signals, and immediate escalation paths. A fail-safe posture should preserve contestability and reduce irreversible harm while operators diagnose the incident.

D. System states & architectures. Operational postures that determine how harm is absorbed—or amplified.

Ethotechnics uses Fail-Safe Mode to extend the d. system states & architectures vocabulary and connect governance, design, and policy teams.
