One ARC authenticates one document. A Master ARC does it for everything at once — all records from a deal, an audit, or a client matter, grouped and certified as one sealed, auditable set. One container, tamper-evident.
Choose the sealed records that belong to the deal, audit, or matter.
Group them into one container.
The group is sealed and certified as one auditable set.
This tutorial is sealed and certified as an ARC: authenticated and tamper-evident.
