What it cannot do alone

Proto cannot supply a missing business approval, invent external payment or posting outcomes, or weaken the server permissions. Reviewed source records and configured integrations determine the available actions. Retain the result of each actual operation and investigate unsupported requirements before enabling automatic execution.

Explain the source of this balance or asset change.
