only the Valium accepts the provided, the other two models compute it based on the data submitted in the transaction and the final shnarf is stored.

Overview
Introduces shnarf as a documented concept: a per-submission hash commitment the finalization contract records, chaining submissions and binding data, state, and proofs.
Adds a Data commitments (shnarfs) subsection under the finalization contract in
smart-contracts.mdx(Keccak composition, proof public inputs, and how recording differs for EIP-4844 blobs, calldata, and shnarf-only validium). Registers the term inglossary.json(and the generated glossary page), links it from the architecture transaction-lifecycle step and data-availability “See also,” and tightens minor wording on data submission models.Reviewed by Cursor Bugbot for commit 2d71761.
