Get Event Stories

The live story cluster(s) this Event belongs to. Reads the Event→Story links (including rehomed links produced by orphan reconnection) joined to the latest, non-superseded story clusters, so a merged-away story is never returned. Usually one story (the canonical); a reconnected Event also carries its re-homed story; a multi-cluster Event lists each live story that covered it. relation is reconnected when the Event was re-homed to this story after its original cluster merged away, otherwise primary.
