class SnapshotIndexes(store: FactStore, rows: dict = dict(), exists: OrderedDict = OrderedDict(), nodes: dict = dict(), membership: dict = dict())

Shared indexes for a caller-owned immutable FactStore batch.

Opt-in: discard this object before changing the store. Materializations, bindings and warnings belong to each engine, never to this cache.
