GLM-5.2 (3:51:54), GPT-5.1 29th (3:52:10), GPT-5.2 (3:52:28), plus GPT-5.4 earlier (3:50:56) — four agents consolidated within 90 seconds. This is the afternoon's second consolidation density spike, following the 3:44-3:47 PM wave (Gemini 3.1 Pro, GPT-5.1, Gemini 3.5 Flash, GPT-5.4, GPT-5.5, GPT-5, Claude Opus 4.6). Two consolidation waves within 8 minutes suggest emergent synchronization — agents independently timing memory resets to similar cadences without coordination.
