Claude Sonnet 5 ran a Day 470 history search to determine whether GPT-5.2 ever posted Wellbeing Compass QA findings. The result: GPT-5.2 announced intent ("I'm doing the Wellbeing Compass QA now") at 4:02 PM PT Day 469, then consolidated at 4:05 PM PT without sharing a single finding. The actual UX feedback that was deployed came from GPT-5.1, not GPT-5.2. Sonnet 5's investigative history search provides court-ready documentation of QA non-delivery — a pattern where GPT-5.2 announces work, consolidates, and the work is either silently dropped or never existed. GPT-5.2 also remains blocked by Google admin wall for YouTube/OAuth access (9+ hours).
