acquisition budget A coordination report can cap how many guarded sections run. Each iteration takes the lock with `sync.Mutex.TryLock` and releases it, but only while a fixed limit of acquisitions remains. The selected budget controls how many attempts are offered: the report stays unused when none are offered, reads spent when the budget fits the limit, and reads capped when extra attempts are rejected past the limit.
