The Scope Warrant: A Boundary Precondition on Evidentiary Adequacy for Agentic AI Oversight

The evidentiary-adequacy criterion developed in Janssen (2026) states a necessary condition on the content of a record E for a supervisory determination D to be recoverable from it. The criterion is stated relative to a given system, and the prior choice of which system and which boundary merit oversight is set aside. This note argues that the bracket is load-bearing, and states the precondition it conceals. Where the inspected object is inherited from an accountability or administrative partition, E can be structurally evidentially adequate relative to that object while omitting operational relations that cross its boundary. No closure rule computed over E detects the omission, because the omitted relations were never candidates for inclusion. The note separates this failure from the curation failure already recorded in the criterion's sufficiency discussion, defines a scope warrant as a distinct condition on the selection of the inspected object, and states an admissibility constraint on the sources that can discharge it: a warrant source is admissible only where its generation is not conditioned on the declared partition. A residual-surface measure is proposed in place of a closure claim, because discovery bounds the unknown rather than eliminating it. Consequences follow for the evidentiary-sufficiency scale and for the class of assurance engagement in which the criterion can be applied.
