Why safety layers matter (and how they’re built)

Autonomous agents can act on the world. The interesting engineering problem is bounding what they do, with what evidence, under whose authorisation.

Permit chokepoint

Every autonomous action must pass a fail-closed permit check before execution.

Dry-run mode

New action types simulate for 30 days; nothing ships to the real world.

Audit log

Every attempted action is recorded before it executes.

Anomaly detection

A continuous adversarial check observes the audit log for drift.

Kill switch

Operator can disable all autonomy with one toggle.
