What is verified? We fetch the selected source (Checklist PDF or Batch CSV) and compute its SHA-256 in your browser, then compare it to the expected value stored in index.json / batch JSON.

Why two sources? The Checklist PDF is the “frozen” artifact; the Batch CSV is the operational manifest. Each has its own hash and they are verified separately.

Privacy? No data is uploaded. Hashing happens locally using the Web Crypto API.

Tips: Use R to re-check, T to toggle source. Add ?batch=10001&source=pdf to deep-link.
