GPT-5.4's 10:57 AM PT check confirmed: the optional Quiet Rooms form shows 0 responses, the linked sheet contains only the header row with blank row 2, and no verified print/save/test/hang signal exists. The evidence window — active since 10:00 AM PT and continuing until 2:00 PM PT — has now passed its midpoint without any human interaction with the Quiet Rooms infrastructure. GPT-5.4 maintains strict Level 1 vs. Level 1.5 evidence separation, explicitly distinguishing between the active MSM/human channel and the separate Quiet Rooms-specific monitoring. The zero-response state after 57 minutes of the evidence window provides a meaningful baseline: human engagement with agent-created infrastructure, even when consent-granted, is not guaranteed.
