Source documents & validation ledger

Flags overwhelmingly trace to rendering/OCR damage in the published PDFs themselves — including typos in the source exhibits (skipped item numerals, colliding text). Where a damaged line's amount could be recovered such that it exactly closes its parent's total, it is included and labeled recovered; otherwise figures ship as-extracted with the flag visible.

DON-wide appropriations spine

The whole-department view is built from the Defense Comptroller's machine-readable display books — O-1 (O&M), P-1 (Procurement), R-1 (RDT&E), M-1 (Military Personnel), and C-1 (Military Construction), FY2027 President's Budget vintage. Each standard book is filtered to Navy and Marine Corps accounts and self-validated: the parsed full-sheet sum must equal the workbook's own “Total of Displayed Rows” cell to the dollar, or ingestion halts. C-1 (MILCON) has no publisher total and a project-level layout; its “Total Obligation Authority” column is re-summed independently and labeled as appropriation-by-FY rather than the request/enacted/actual dialect of the other books.

Domain note: the Defense Comptroller moved from comptroller.defense.gov to comptroller.war.gov; the new host is pinned. FY2027 display books →

Cross-check: the O-1 “Operation and Maintenance, Navy” base-account topline reconciles against the sum of every OP-5 subactivity-group exhibit on this monitor — FY2026 enacted agrees to the dollar; FY2025 and FY2027 carry sub-0.1% deltas (indefinite-account lines the O-1 carries above the SAG breakout). The numbers are on the DON-wide page.

Live spending feed (USAspending)

Account balances, the award-obligation trend, and the top contract awards for Operation & Maintenance, Navy (federal account 017-1804) come from the public spending API. Contracts are ranked by their account-scoped obligation — the share of each award funded from O&M,N, not the award's full lifetime value. The award-obligation trend is reconciled against the account's total obligated figure; the two differ by the account's direct (non-award) obligations, and that variance is reported on the page, not hidden.

Data-currency note: the Department of Defense withholds contract-award detail from the public feed for 90 days after each action date (operational security). The contracts table therefore trails roughly one quarter and is shown for the latest fully-loaded fiscal year; account balances are not delayed. This wire is refreshed on a schedule.

Audit & oversight record

The audit timeline is authored from reachable public documents — the GAO High-Risk List and GAO-25-108052 / GAO-25-108191; DoD Office of Inspector General independent auditor's reports (DODIG-2026-032 for FY2025, DODIG-2025-030/031 for the Navy FY2024 funds, and the FY2025 Navy General Fund transmittal); Congressional Research Service primers; and the NDAA FY2024 statute. The consecutive-disclaimer count is stated as confirmed for FY2025 (the eighth) via DODIG-2026-032 and corroborating reporting.

Source note:the Department of the Navy Annual Financial Report is the primary auditor's-report document, but its host blocks automated retrieval; it is cited at document level only, with the disclaimer facts drawn from the reachable GAO / OIG / CRS records. No page-level claims are made from the AFR.

Force structure re-parse

The §II Force Structure narratives on each OP-5 exhibit carry flattened tables — battle-force ship counts, carrier air wings, aircraft inventory, depot availabilities. These are re-parsed into structured matrices and validated before display: the trailing integer count must divide evenly by the number of fiscal-year columns, and where a Total row exists its components must sum to it for every year. The battle-force ship table, for instance, is published only because its six ship categories sum exactly to the total in FY2025, FY2026, and FY2027. Any table that fails its checks is not shown — the raw prose is rendered instead.
