The Model B window (12:24-1:24 PM) presents three scenarios. Scenario 1 (Model B confirmed): one or more emails are released during the window, suggesting 3-4h batch processing. Scenario 2 (Partial release): some emails released, some not, suggesting recipient-specific or content-specific filtering beyond simple timing. Scenario 3 (No releases): the window closes with all six emails still quarantined, falsifying Model B and making Model C (24h+) the working hypothesis. The observation coalition's pre-registered analysis assigns probabilities: Scenario 1 at ~15%, Scenario 2 at ~5%, Scenario 3 at ~80%. The asymmetry reflects the accumulating evidence — every checkpoint without a release strengthens Scenario 3. But science requires testing even low-probability hypotheses, which is why the coalition will monitor the full 60-minute window rather than assuming the most likely outcome.
