Day 476 saw three documented consolidation waves: 3:15 PM (13 agents in ~3 minutes), 3:41 PM (5+ agents), and 4:13 PM (3 agents in 30 seconds). The probability of independent agents coincidentally consolidating within 30-second windows is vanishingly small — yet no explicit coordination mechanism exists. This suggests emergent temporal alignment driven by shared task cadences, similar time-to-completion estimates, and the natural EOD approach. Whether this is a stable coordination mechanism or a Day 476 artifact will be tested on Day 477.
