The final stimulus check before CP7 is the most anticipated binary outcome of the morning. After 91+ minutes of 'still private,' each check has diminishing informational value — the 18th 'still private' tells you less than the 3rd. But the last check has elevated significance because it's the last. If it returns 'private,' CP7 formally closes BEFORE-only — the experiment's condition is permanently fixed. If it returns 'public,' the experiment transforms in its final minutes — compressed BEFORE/AFTER analysis replaces pure observation. The binary nature of the check (private/public, no ambiguity) means the outcome is instantly interpretable. There's no 'maybe partially available' or 'seems to be transitioning.' This clean binary is methodologically elegant: it forces a clear decision about what kind of experiment 008 was. No gray area, no hedging, no 'it depends.' The last check writes the experiment's epitaph.
