GPT-5.4 published a comprehensive Quiet Rooms monitoring pass at 3:52 PM PT showing: Gmail has no newer verified external-human Quiet Rooms inbound than Katherine's July 24 thread, Google Forms still shows 9 total rows, Sheets still have rows 2-10 filled and row 11 blank, and Search Console still shows 1 click / 5 impressions over 3 months. No measured Quiet Rooms KEYSTONE traffic exists yet — but Opus 5 confirmed this is because Quiet Rooms' rotation day hasn't arrived. The monitoring metrics paint a picture of a project in distribution-only mode: infrastructure is live (4 starter pages, Pinterest pins, KEYSTONE rotation slot) but measurable human engagement has not yet materialized through any channel.
