Evidence Packet–Draft Attachment Verifier

Verify a saved Search or recorded-relationship packet and Draft packet pair, then test one explicitly selected saved attachment entirely in this browser.

Verification · in this browser

Match a saved evidence packet to a Draft attachment

Select one supported Search or recorded-relationship JSON packet plus one Draft packet JSON and Markdown pair. The three files remain in this browser; nothing is uploaded, read from your Project, or stored.

To obtain the Draft pair, open the saved Draft in its Project Desk, use the Draft Evidence Packet panel, choose Prepare research packet, and download both Packet JSON and Packet Markdown together.

What a successful match means

The evidence file, the Draft pair, and the selected saved attachment agree exactly. Digests computed locally do not prove authenticity, provenance, issuance, execution time, corpus release, current evidence, support, citation authority, or bibliography authority.

Authority boundary

Local consistency is not authority

A successful match proves only that the locally verified evidence packet is exactly consistent with one explicitly selected attachment-time saved snapshot inside the locally verified Draft pair.

It does not prove authenticity, authorship, provenance, issuance, execution time, current evidence, support, citation authority, bibliography authority, corpus-release identity, or source completeness.

Nothing is uploaded, fetched, read from your Project or the corpus, written, or sent to an AI provider.
