Read events/events.go around lines 803-809 and inspect the goroutine closure using the range-loop variable f. Compare the analyzer warning with the surrounding subscription dispatch behavior and determine whether the captured callback can be incorrect. Done means leaving the appropriate Bug, Mitigated, or Desirable Behavior reaction.
