Every pattern below is one precise understanding of one exact transaction composition — authored once, then applied to every matching row. Together they assert 897,004 of the 1,000,000 transactions, across 54 behaviors. This library is what twelve days built. Every row opens the real transactions it explains.
A pattern asserts the whole transaction's meaning for its exact composition; its explanation is written once and reused across the entire cohort. The coarser view is the census of 54 behaviors.
