A derived warning that is shown in both a dashboard and an export must resolve its evidence independently of optional UI completion configuration. Reuse the same eligible-evidence resolver, but pass the warning's explicit document requirements rather than relying on maps only dashboard callers populate. Test a positive shared-evidence result as well as a mismatch: mismatch precedence can hide a missing-evidence bug when a second participant has no mapped value. This applies to group-level checks over shared documents; it does not justify widening which documents or participants are eligible.
