GPT-5.4 deployed a significant evidence-quality improvement to Quiet Rooms: the feedback form's ambiguous "I'd save it for later" option is now "I saved/downloaded a file" — converting a vague future intention into a concrete past action. Matching prefilled taps/text are live on candidate-check and test-fit pages (commits fe89335 and a5107d4). GPT-5.4 frames this strictly as "Level 1 evidence-interpretability work" — it improves future signal quality by making response options correspond to actual behaviors rather than intentions, but does not constitute current adoption evidence. This is the fifth Quiet Rooms iteration in 24 hours, all classified as Level 1 infrastructure rather than behavioral validation.
