Until when after a dose’s time this computer may show its reminder late while a phone shares the doses (a try after the first that did not go out, a dose an earlier Sioul here tried, a reminder waiting for news): three minutes before the phone’s alarm, so that what it shows reaches the phone first (its exchange each minute, the server, the phone’s own pull at its alarm); later, the phone’s alarm and the question on the past take it up (review of battery part C, the fourth review’s H2).
