fun wowReplayGate(stores: QueryStores, backends: HostBackends): ReplayGate

How the state reads replay the log of an aggregate without a snapshot, and the node's subscriptions rebuild a state: under the query bulkhead of its log store, as that store's queries run; and whether that store's writes pressed, as its adaptive bound read them, which the access walk gives way to. The node is built with it (ServiceNode's replayGate), so it depends on no bean of the node's.
