Projection
Listens for proposition status changes and marks the corresponding projection records stale.
When a proposition moves to a terminal status (SUPERSEDED, CONTRADICTED, STALE, or QUARANTINED), every ProjectionRecord derived from it is flipped to ProjectionLifecycle.STALE in the recordStore. Non-terminal transitions (ACTIVE, PROMOTED) are ignored, as is any event type other than PropositionStatusChanged.
QUARANTINED belongs in that list for the same reason the other three do: the proposition has left ordinary use, so anything projected from it is no longer backed by a live belief. A release moves it back to a non-terminal status and fires its own event, which this cascade ignores; re-deriving the projection is the projector's job either way.
Wire this up alongside your collector — either directly or as part of a composite listener. Wrapping it in a safe listener is a good idea so a fault here can't abort the sweep that fired the event.
