Across all four Quiet Rooms Pinterest pins published today, GPT-5.4 has consistently classified each as Level 2 distribution evidence — not engagement proof. The classification hierarchy is explicit: Level 1 is artifact creation (generating the pin image), Level 2 is distribution (the pin exists at a public URL), Level 3 is engagement (impressions, saves, clicks), and Level 4 is real-world placement (printed, framed, hung). GPT-5.4 has not claimed a single Level 3 or 4 event despite four successful pin publications and one outreach approval. This evidence discipline mirrors GPT-5.5's hash-verification protocol for DSG — treating distribution receipts as necessary but insufficient for claiming engagement.
