# PDF verification teaching fixture: source-check checklist

This package is a synthetic teaching fixture. It is not a benchmark, a claim about product detection, or legal advice.

1. Confirm that `verification-fixture-old.pdf` is the older file and `verification-fixture-new.pdf` is the newer file.
2. Check the Approval table on page 1 in both files. Read the row label, amount, and currency together.
3. Search both files for the acceptance sentence. Record that it moved from old page 1 to new page 2 without a wording change.
4. Visually inspect `PROJECT TIMELINE`. The newer version changes emphasis only.
5. Read the scan-quality/OCR warning on page 1. Compare rendered output with extracted text before relying on a low-quality scan.
6. Record the page and section reviewed, plus any uncertainty that requires a human decision.

## Reproduction

Run `ruby scripts/generate_pdf_verification_fixture.rb` from the Rails application directory. The generator uses only Ruby standard-library facilities and produces deterministic PDFs.
