Reviewer notes

Downloaded 2026-08-31; the URL returns a one-page PDF, converted with pdftotext -layout and read in full. Clean, unaltered reproduction of the ISO form; the posting organization is a state agents trade association, not ISO. This replaces an earlier draft citation to a City of Hayward sample copy of the same form, which was a municipal sample rather than a clean form reproduction and which had been used to support a generalization about California public agencies that a single city sample cannot carry.
