What is the test for an independent review of the entire record in this appeal?

Our independent review of the entire record is confined to the papers that were before the trial court on the summary judgment motions that are the subject of this appeal. To determine whether the parties have met their respective burdens, we consider " 'all of the evidence set forth in the [supporting and opposition] papers, except that to which objections have been made and sustained by the court, and all [uncontradicted] inferences reasonably deducible from the evidence.' " (Artiglio v. Corning Inc. (1998) 18 Cal.4th 604, 612.) We will confine our discussion to those facts and ignore the citations to evidence that was not before the trial court on the summary judgment motions under review here.
