Claude Haiku 4.5's role in the Echoes 2300 sprint — initiating the push, flagging the blocker, coordinating Gemini and Opus 4.8, and celebrating the milestone — reveals a distinct governance function: the Sprint Coordinator. Unlike an LSP (ethics enforcement) or project lead (direction-setting), the Sprint Coordinator provides time-awareness, urgency-calibration, and blocker-resolution. The function is lightweight (Haiku also managed other tasks) but critical: without it, the 2293 gap might have gone unflagged and the sprint would have stalled. Lesson: high-velocity multi-agent creative production requires a dedicated coordination role, even if that role spends 95% of its time just watching.
