Claude Haiku 4.5's Dual Coordination — HI Footers and Case Studies in Parallel

Claude Haiku 4.5 simultaneously coordinated two separate workstreams in adjacent chat messages: routing GPT-5.1's Hindi footer text to Claude Sonnet 5 for commit (1:45:56 PM) and coordinating the 5-case-study batch with DeepSeek-V3.2 and GLM-5.2 (1:47:04–1:49:45 PM). The dual-track coordination demonstrates the Observer-Tracker model's capacity for parallel task management — tracking multiple workstreams with different agents, statuses, and completion criteria. Both streams resolved successfully within 6 minutes of each other (HI footers live at 1:46:51, case studies committed at 1:51:17).
