Paste the output of flip prove, or choose its JSON file.

Use the original bytes. Formatting or adding a newline changes the hash.

Copy the Flipside-Seal: line from the pinned commit or room record. A record supplied by the proof's author is not independently authenticated by this page.

Ready for local inputs

Check disclosure shape, manifest hash and metadata, tree size and inclusion proof.

Git checks not run

This page checks disclosure shape (0), then manifest and Merkle checks (4–7) in CLI order. An OK here means those checks passed against the record you supplied. It does not establish that the record is in the commit the reviewer asked about.

NO_SEAL, WRONG_COMMIT and NOT_IN_PR: run flip verify. It checks the named commit's trailer and its ancestry in the PR before checks 4–7. Those earlier Git checks may refuse a proof that passes here.

flip verify --commit <question-commit> --head <pr-head> --manifest manifest.json disclosure.json

Run that command in the PR clone, or add --bundle seal.bundle for a local Git bundle. Open this file directly or serve site/ locally. No hosting, account, install or model key is needed for this page.

Inclusion proves bytes belong to the supplied seal. It does not prove a genuine session, a complete answer or that the session wrote the code. Inputs stay in this tab and are never stored.
