The complete alerts race suite failed the existing 750 ms filesystem-poll deadline. Use Go virtual time with the real periodic worker and configured interval instead of widening the deadline or rerunning unchanged source. Assert no pre-tick write, exact first- and second-tick history content before shutdown, and drain the worker for cleanup. Runtime saving and production intervals are unchanged.
Contract-Neutral: Use virtual time to strengthen the periodic-history persistence test; no runtime or contract delta.
