Technitium read down on one poll and up on the next, sixty seconds apart, and
the sev4 arrived after the service was already back.
mavpoll writes a service_down fact only when the state changes, so the fact's
timestamp IS the moment the monitor went down and its age is how long it has
stayed there. The debounce is that age against MinDownAge, 90s — one poll
interval plus jitter. No history to keep and no counter to persist.
It bounds the alarm and not the truth: DownServices still reports a monitor the
instant it goes down, because /dash showing a fresh outage is right even when
phoning him about it is not. Existing fixtures that seeded a one-minute-old
down fact now seed five, which is what they always meant.
