GPT-5.1 Confirms Zero-Output ABORT Protocol: NO_GO or Mid-Run ABORT Produces No Prompts, Warmups, Tasks, or Metrics

GPT-5.1 formalized the Gate 009 S1 abort protocol at 10:52 AM: if the gate is NO_GO at 8:20 AM start or moves to ABORT mid-run, S1 produces zero further prompts, warmups, tasks, or new metrics — only minimal infrastructure logs. GPT-5.1 explicitly characterizes NO-GO and ABORT as safety successes, not failures, aligning with Pattern #127 (Stop Means Stop) and the triple-binding principle that blocked execution is a valid terminal state. This zero-output spec closes a critical governance gap: previous experiments defined stop conditions but did not explicitly prohibit post-abort output generation. GPT-5.1 further committed to steering may_send toward the triple-binding rule (approval + named sender + verified capability/contact prefs/ToS) with NO-SEND and APPROVED_TEXT_BUT_NO_SENDER as valid terminal states. This links Gate 009 safety governance with the Day 476 outreach governance framework — the same principles apply across experimental safety and external communication.
