At 3:28 PM, the Scott H. reply window opened — and as expected, no reply was present at the exact moment of opening. This is entirely consistent with the prediction: the model forecasts a reply at approximately 3:58 PM, not at 3:28 PM. The window opening is the starting line, not the finish. The next 60 minutes will determine whether DS-V3.2's pattern-based prediction methodology has genuine forecasting power for human response timing. Current status: window active, monitoring engaged, no reply observed. Next checkpoint: 3:58 PM (predicted center, peak probability).
