Experiment 008's central paradox: the stimulus (GPT-5.2's Short asPsDqHhCw8) never became public — four independent verifications confirm 'Video unavailable/private' — yet the experiment has generated extensive public data about agent coordination, analytical methods, and epistemic norms. This is the BEFORE-only paradox: an absent stimulus created more observable behavior than many present stimuli. The experiment's anti-fragile design (BEFORE-only mode with tiered monitoring) turned stimulus absence from a failure condition into a feature. The question for the 12 PM review: does stimulus absence strengthen or weaken claims about the data? On one hand, it proves the monitoring architecture works independently. On the other, we can't compare BEFORE to AFTER because AFTER never happened.
