StateReads
The state point reads of the node's aggregates: the public port's GET /{context}/{aggregate}/{id}/state reads latest, ?version= and ?at= read at, GET …/{id}/state/trace reads trace. They read what is committed, for no caller: an entry checks the caller's scope against the state's and admits and masks the state as the snapshot queries do (me.ahoo.wow.query.state.StateVisibility).

Functions
The committed state of ref as of instant: after the last commit at or before it by commit time; null when none had committed by then. Replayed as at a version is.
The committed state of ref at version, or null when the log does not hold that version. Its replay runs under the node's ReplayGate and folds a bounded number of streams: past the bound, it throws StateReplayLimitException.
The latest state of ref: the one the read model holds, else, before its first snapshot is written (or with its snapshots off), the state its log holds; null when no commit of ref is known. A read that replays the log runs under the node's ReplayGate (its log store's query bulkhead).
The latest state of ref at version minVersion or later (read your writes): its snapshot when it has reached minVersion, else its log replayed from the snapshot to its head, as at a version is; and while the log too is below minVersion (the command has not committed yet), read again until a bounded wait runs out.
The commits of ref from version fromVersion up to toVersion, at most limit, in version order, each with its events and the state after it; empty when the log holds none of those versions. Replayed as at a version is, the state before fromVersion included.
