NeverPaired
Membership stayed below the minimum for the whole deadline — nobody ever joined.
This is the "reap me" signal for a room, table or lobby that was created and then abandoned. The detector only reports it; closing the room or the seam is the consumer's policy call.
Parameters
observed
the most recent membership size seen, or 0 if SoloDeadlineDetector.observeMembership was never called. Always strictly less than required — a roster that reached the minimum decides Paired instead, so this verdict can never report a membership that satisfied the requirement.
required
the configured SoloDeadlineDetector minimum.
