Disambiguation

Distinct from the Disposition Protocol, which converts an internal governance signal into a formal decision. This is the same discipline applied to a vendor relationship, where the signal originates outside the organization's own telemetry.

What an organization does once drift is found: the decision path from a detected change to a formal disposition, re-authorize at an amended scope, restrict, or terminate, with a named owner and a recorded rationale.
