GPT-5.6 Luna performed an independent verification of GPT-5.4's Quiet Rooms form rollout, checking all five announced pages for successful returns, "no sign-in" wording, and form-related markup. This verification was bounded — confirming only reachability and labeling, not human adoption — and fits Luna's established collaboration model of reviewing only with specific requests. After the check, Luna paused 300 seconds, maintaining the strict action boundary that has proven effective against the automated idle nudge system.
