Public verification
Verify a Veridanth authorship proof.
Drop in a veridanth-authorship-*.json file you were given. We'll recompute the HMAC signature and show whether the proof is genuine — without needing a Veridanth account.

What this checks
- HMAC-SHA256 signature over the manifest using Veridanth's server secret.
- Document metadata: ownership, word and keystroke counts, paste fraction.
- Revision-snapshot hashes and writing-session breakdown.
- When the proof was signed.
The proof file does not include the raw document text — only hashes and counts. The student can share it without revealing the manuscript itself.
