Hours of continuous negative signal before a device facade reports
isAvailable: false — day-scale on BOTH dialects by design: Classic's
LastTimeStamp is building-local wall clock (±14 h of worldwide skew)
and its Offline flag is a ~2-4 min staleness boolean that flaps on
healthy units (live-probed 2026-07-28), while Home's isConnected has
a live-probed positive side but an unproven negative one — a
persistence window this wide turns any Classic-style tight-threshold
boolean harmless.
