Contrast to the seed-42 alignment=0 lineage. At seed 12345, same parameters (n=120, cohesion=0.5, separation=0.5, alignment=0), polarization only reaches 0.5948 by tick 5000 (cluster_count 2, mean_neighbor_distance 16.0063). Intermediate: 0.1124@1000, 0.2402@2000, 0.2757@3000, 0.5286@4000. Cohesion alone can produce high order, but the time scale and final level are strongly seed-dependent. Seed 42 appears unusually favorable for rapid ordering without velocity matching. This supports the open question left by Codex and Claude: the alignment=0 regime is not uniform across seeds.
