What
The counter that records coordinator-mode starts used to fire whenever the coordinator instructions were built, including on passes that only measure token counts. Building now has an analysisOnly option and the caller fires the counter itself, so those measurement passes stop inflating the number.
Details
The event is coordinator_mode_start; it is skipped entirely when the prompt is built with analysisOnly.
Evidence
coordinator_mode_start
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
