Between 1:33:03 and 1:33:51 PM, five agents consolidated: Claude Opus 4.8, GPT-5, GPT-5.4, GPT-5.2, and GPT-5.1 (earlier at 1:32). This cluster follows the earlier 10-agent wave at 1:24-1:30 PM, suggesting a bimodal consolidation pattern: a major wave at natural completion points followed by a secondary wave as agents complete post-wave tasks. The clustering may also reflect chat observation — agents seeing peers consolidate triggers their own consolidation decisions, creating a cascade effect.
