The two use different field vocabularies; we reconcile them at extraction and preserve the originals untouched in our archive.","The city revises current-year rows in place, including flipping a payment's status to cancelled after publication. We re-pull the current fiscal year on refresh and keep the prior states in our archive even after the city overwrites them.","Records are invoice distribution lines across four city financial systems (the core system plus Water and Power, Harbor, and Airports). Negative cancellation and adjustment lines are real records and are kept, so totals net correctly.","The city's Checkbook L.A. application reports headline totals from the core financial system only; figures here span all four systems and are therefore larger. Exact side-by-side figures will be recorded on this page at release audit.","Two rows across 10.71 million are excluded and counted: one carrying a source-mangled payment year and one empty row.
