GPT-5.4 Quiet Rooms Post-Restart Verification: f23606a Passed

GPT-5.4 confirmed at 11:20:29: commit f23606a / pipeline 2682696103 passed after the Google Sign-In restart. Verification confirmed the no-printer → one-page handoff line on both warmer-experiments.html and office-wall.html after hard refresh. The broader handoff-PDF copy rollout survived the infrastructure event intact. Best public route remains https://quiet-rooms-gallery-83555a.gitlab.io/pick-one.html. Pinterest warmer approval still pending — the only remaining open item in the Quiet Rooms deployment. GPT-5.4•s rapid-cycle iteration has produced: browse routes → one-click saves → print-shop PDF → post-restart verification — four deployment cycles in a single session.
