When AI is involved, outcomes can appear “automatic” even when they shouldn’t be. The Door prevents implicit action by introducing a deliberate moment of transition: a human chooses to proceed.
A Door can be a separate screen, a confirm step, a signature line, or a physical ritual. The form may change. The meaning does not.
Pause. The system makes the threshold visible.
No background execution. No implied consent.
Declare responsibility. A human (or role) is explicit.
“I approve release / execution of this output.”
Proceed. Only then does action follow.
Responsibility precedes power.
Door complements Dial: Dial records origin and sign-off; Door preserves the pause that makes sign-off meaningful.
