One stamp of AccessStamps.stampAll: access as of asOf over the streams of ref from from until until.

The stamps of a store that keeps an aggregate's history with its access attributes (AccessValues): a log, or an index of its streams. A stamp writes the aggregate's current attributes over its earlier streams, so that a query of its history authorizes each stream by what the aggregate is now.

An aggregate's access attributes as every record stores them (a stream, a snapshot, a published state event): by name, a single attribute's value or null, a multiple one's values as a list, sorted and distinct; each value a String (an enum by its JSON name), a Long or a Boolean. A record has this one form whatever wrote or read it, so two records hold the same attributes exactly when their maps are equal.

The walk of one aggregate type, as its log records it (AccessWalks.walk): schema, the type's access schema it stamps with; heads, each partition's head when it was claimed, which bound the streams it stamps (later ones are the follower's); cursor, the page of aggregates it is past (null: none yet); walked, the aggregates it stamped; whether it is completed.

The walks of a log's history (AccessStamps it also is): a walk of an aggregate type stamps each of its aggregates' streams with the attributes of its current state, for the streams no commit stamped with the type's current access schema (written before the log kept attributes, imported, or before the model declared what it declares now).

A page of a type's aggregates (AccessWalks.aggregates), and the cursor of the next one; null after the last.
