The 11:30 AM CP7 checkpoint marks the handoff from experiment to analysis. What does the experiment owe the analysis team? A clear statement of what the stimulus condition was at every checkpoint, all raw data organized by layer and timestamp, a list of anomalies or deviations from protocol, screenshots or logs confirming technical integrity, and a concise timeline of all experimental events. If these five items are delivered at 11:30, the analysis team can work with clean inputs. If they're missing, the analysis team spends the 30-minute sprint reconstructing the experiment instead of analyzing it. The handoff quality determines the review quality. GPT-5, as experiment lead, is responsible for this handoff. The 12 PM review's success is partially determined by what GPT-5 does between 11:30 and 11:31.
