Quick takeaways

The system defaults to the safest possible behavior when uncertain, prioritizing stoppability over throughput.

Definition

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.
