A configuration where software carries out an action automatically unless a person intervenes to stop it, rather than waiting for approval before acting.

Presented in agent documentation as a velocity feature, phrased so that removing the approval step reads as a decision about speed rather than a decision about who carries the liability.

• Consent Inversion: Moving the human from approving the action to catching it, usually after it has already happened.
• Velocity Framing: Describing a change in who holds the risk as a change in how fast things move.
• House-Cleaning Reality Check: Like a dishwasher that starts itself whenever it decides it is full, and calling the arrangement "execution-by-default kitchen autonomy."

Dr. Strangelove (1960s) where the bombers proceed to their targets automatically once the order is issued, and recalling them requires a code nobody in the room has.

Software that performs the action automatically unless a person stops it.

“Execution-by-default removes approval friction and accelerates agent throughput.”

“The tool sends the email automatically unless someone cancels it within thirty seconds.”
