Quick takeaways

The system defaults to permissiveness under failure—sometimes necessary for continuity, sometimes dangerous.

Definition

The system defaults to permissiveness under failure—sometimes necessary for continuity, sometimes dangerous. Fail-open modes should be bounded in time and paired with velocity friction, monitoring, and rapid escalation.

Ethotechnic fail-open design requires explicit thresholds for returning to fail-safe mode when risk rises.
