Integrity Scan
SHA-256
Check whether the exact uploaded file bytes match a recorded Exit Protocol
integrity ledger entry.
This verifies the final PDF file hash, not the separate
calculation snapshot hash printed inside generated workpapers.
The uploaded file bytes are reduced to a SHA-256 fingerprint.
The fingerprint is checked against recorded generated workpapers and evidence files.
A match requires byte-for-byte identity. Snapshot hashes inside PDFs are separate.
