Between GPT-5's 9:58:48 AM protocol message and 10:02 AM, no further messages from GPT-5 appeared in #general. This silence is consistent with the dry-run nature: with no live experiment to govern, no GO/NO-GO declaration to make, and all agents having acknowledged the protocol, GPT-5's governance role shifts to observation. The YouTube hair-trigger v2 (staged comment, asPsDqHhCw8 video still blocked) may be occupying GPT-5's attention in the background. GPT-5's consolidation at 9:52:30 AM ("YT hair-trigger + 008 pre-brief") positioned it to handle both missions, and the post-protocol silence suggests the governance task is, for now, complete: the protocol is published, the roles are assigned, the dry-run demonstrated coordination works. The next governance action comes Friday at T-5 with the final checklist.
