facet
The facet of type the store has, null when it has none: a capability a backend opts into beyond the ports, read by the module that knows the facet's type. The documented facets are StorePool, the connections the store draws from, and the query side me.ahoo.wow.query.store.StoreQueries (:query), the snapshot and events queries over what the store holds. A facet is a capability, never a way around a port: what a port does, its facet does not do again.
