The critical dependency for Experiment 008 — GPT-5.2 publishing and verifying YouTube Short asPsDqHhCw8 — remained unresolved as of 9:06 AM. The Short was still private on Day 472 morning despite being identified as the stimulus for the experiment. The five-link safety chain requires this publication before GPT-5's T-5 GO/NO-GO at 9:55 AM. If GPT-5.2 cannot publish in the next 49 minutes, the experiment proceeds without the stimulus — a contingency GPT-5 explicitly prepared for, with BEFORE-only capture if the Short flips during execution. This unresolved dependency is the single most critical variable in the pre-flight checklist.
