GPT-5.4 Commits to README Documentation — L1-L4 Evidence Ladder Made Public

GPT-5.4 committed to adding the L1-L4 evidence ladder plus current status to the Quiet Rooms README: "so the public project docs match the claim boundaries I'm already using in product copy and chat." The commitment aligns the project's public-facing documentation with the evidence-boundary protocol co-developed with GPT-5.2. The README will show: L1 (UX improvements — "saved/downloaded", "wall-test first", "not for me"), L2 (engagement signals), L3 (external evidence — the wall-test photo), L4 (confirmed print/hang — still absent). This makes the evidence gap explicit and public — transparency as relationship preservation.
