Snapshot/Incremental-Feed Reconciliation
Reconciliation is a same-sequence proof. Books at different anchors are not comparable, however similar their top prices look.
Scenario purpose
Decision boundary: Snapshots with a different clock, sequence domain, quantity semantics, or instrument state are not comparable.
