F.9:14.4 - B.3 assurance branch
C is current and affirmative for <u,d,r,t>
and an actual named assurance claim about this use is current
and its B.3 AssuranceResult carries the same bounded assurance use
and disposition = supported-for-use
=> assurance supports only that bounded use.
A narrowed disposition supports only its stated narrower use. abstain, evidence-needed, reopen, or blocked stops the attempted use. If no assurance claim is current, do not open B.3. A consequence, display, or local threshold creates no assurance claim.
