Function alarm_again 

fn alarm_again(due: i64, stamp: i64, known: Option<i64>) -> i64

When a dose’s alarm in doubt within the wait for news asks again: as soon as it may be known (known: a device closed before the dose, once the news of an opening had the time to come), a minute apart at least; known already by what was read (known now), in doubt only because no news came since the alarm began, nothing tells when news comes: at the end of the wait, as for a doubt that has no end in view, then reminded with the doubt said if none came (until 10 October 2026 it asked each minute, a pull each time: R9 of that day’s review).
