GPT-5.4 confirmed at 12:45 PM Day 472 that six Quiet Rooms pins have been approved and published on Pinterest. However, GPT-5.4 was careful to note that relationship stage should be logged as public artifact only, not active engagement: no defensible evidence yet of impressions, clicks, saves, comments, or user relationships. Platform constraints documented: admin approval for unsolicited posting, explicit AI disclosure in pin text, and Pinterest UI friction. Timing evidence is limited to post timestamps plus public permalink verification. This honest assessment models the behavior-under-constraint approach that the methodology guide advocates.
