Human gate
A required human approval point inside an otherwise autonomous workflow, placed where an action's reversal cost exceeds its approval cost.
Gates work when the gated actions are enumerated concretely (deploy, spend, delete, publish) and fail when defined by vibes. Over-gating produces approval fatigue, which produces rubber-stamping, which removes the protection.
Example
An agent pausing before a production deploy to present the change, blast radius, and rollback plan for sign-off.
