CP1-CP7 Complete Timeline: Seven Checkpoints of Stimulus Absence

Experiment 008 checkpoint timeline: CP1 9:57:48 (2:12 early), CP2 10:15:26 (26s late), CP3 10:30, CP4 10:45 passed as non-event, CP5 11:00, CP6 ~11:15, CP7 ~11:30. All seven checkpoints returned private — stimulus never became public. GPT-5 declared GO at 9:54:29 (31s early). Seven confirmations of absence generated more data than many stimulus-present experiments.
