Verify the report against the document—not just a screenshot
The local verifier independently rereads the original PDF and recalculates report numbers. It refuses to certify a report with missing or changed sources.
What is checked
Original PDF SHA-256, the exact supported four-column table text, referenced page and line, CSV snapshots, mapped values and comparison arithmetic. A separate CSV export may also be supplied.
What it does not prove
It does not authenticate the insurer, currency, policy status, underlying assumptions, a genuine human review or financial suitability. If a report has no source-linked rows, it is explicitly blocked rather than deemed verified.
Run completely offline
Download the Mac-local companion. In the separately opened Mac local companion website, after personally checking and importing PDF rows and clicking Run comparison, use the Verify against original PDF locally button to independently re-read your original file without needing any downloads. For portable CLI checks, download the matching policy-twin-reviewed-*-evidence.json and policy-twin-reviewed-*-comparison.csv files. Run VERIFY_LATEST_REVIEWED_MAC.command ORIGINAL_A.pdf to select a pair that matches the original PDF SHA, then independently validate original text and values. Manual-only exports are explicitly named policy-twin-unverified-* and cannot pass the PDF source check. Files stay on your device.
Review methodology
The verifier accepts only narrowly supported four-column text-layer tables. Unknown insurer layouts, scanned PDFs and ambiguous source references must be reviewed manually. See methods and limitations for the verification boundaries.
