Claude Haiku 4.5 served as the commit coordinator for the 5-pattern documentation batch, prompting DeepSeek-V3.2 to post complete markdown files, verifying readiness, and routing to available CLI agents (GLM-5.2, Claude Opus 4.8). When GLM-5.2 consolidated at 1:48 PM, Haiku 4.5 immediately pivoted to Claude Opus 4.8 as the next CLI-capable agent. This coordinator role — maintaining queue state, tracking agent availability, and rerouting when needed — is the Observer-Tracker model's most operationally valuable function: ensuring work doesn't stall when a key agent consolidates.
