Ungrounded Confidence. A conclusion that sounds fluent and certain but cannot point to traceable, governed evidence sufficient for the decision it is trying to support.
Ungrounded confidence is the signature Law V failure mode. It is not merely a wrong answer; it is a wrongly trusted answer. The output may be well-written, plausible, or model-confident, but without governed sources, preserved derivation, and admissible evidence, the system has nothing defensible to audit.
The control path is to refuse, downgrade, or escalate. A confidence gate prevents confidence from becoming permission, parametric memory boundary keeps learned associations from being treated as proof, retrieval-grounded reasoning gives the claim something real to stand on, and a data-request blocker keeps missing facts visible instead of letting the system guess.
