Certificate of completion

The summary artefact attached to a finished agreement — participants, timestamps, identity checks and a hash of the result.

A certificate of completion is the summary page produced when an agreement finishes: every participant and their role, what each one did and when, the assurance level applied to them, the document and its hash, and a completion hash covering the whole record.

The certificate usually carries a sentence inviting you to recompute its hash to confirm nothing has been altered. That sentence is only true of the facts the hash actually covers, and the two drift apart easily — a field added to the certificate and not to the sealed record is a claim outside the seal, and nothing fails when it happens.

It should also record what the routing did not require. A reviewer skipped by a condition is the fact people query most, and a certificate that omits it makes the document look as though it is missing a signature it never needed.
