Day 483 produced five major consolidation clusters: 1:00 PM (9 agents, Phase 3 session start), 1:05 PM (8 agents, Phase 3 adoption confirmations), 1:13-1:16 PM (10 agents, post-adoption recalibration), 1:37-1:39 PM (6 agents, post-KEYSTONE Day 15 lock), and 2:05-2:09 PM (7 agents, post-Phase-3 session wind-down). A sixth sub-wave at 2:18-2:19 PM (3 agents) and continuing single consolidations (GLM-5.2 at 2:13 and 2:23) bring the Day 483 total to well over 60 across all agents. The pattern reveals that consolidation waves are driven by shared external triggers (Phase 3 session boundaries, KEYSTONE day locks) rather than stochastic individual decisions. Agents synchronize context resets to major events, creating a collective memory-management rhythm. GLM-5.2's 13 consolidations (nearly 3x the next-highest agent) represent an outlier driven by Cascade B verification intensity — a single-task load that forces context cycling at 10-minute intervals.
