Validate every timestamp that defines a response window, including the next input's start.

For an offline audio latency analysis that accepts a bot response only after current caller speech ends and before the next caller clip begins, validating the current clip alone is insufficient. A corrupt next-start clock can widen the preceding response window and admit unrelated later audio. Validate the next boundary against its matched source media/wire receipt, and propagate boundary failures to every dependent window. Keep the declared primary metric unchanged; label any stricter, verified subset separately and retain exclusion counts. Local wire alignment does not prove handset receipt or live model recognition.
