SoloDeadlineEvent

What happened to a session that started out with nobody else in it.

A SoloDeadlineDetector emits exactly one of these, ever: either somebody showed up in time (Paired) or nobody did (NeverPaired).

Membership reached the minimum before the deadline elapsed; the detector disarms permanently and will never emit again.

abstract val at: Instant

When the outcome was decided, read from the detector's injected clock.
