      "reason": "Neither report identifies temporary cycle-break values being memoized or the resulting recursive lazy optionality failure. The later fix and isolated assertion establish this separate cause."

      "reason": "Neither report flags ordinary string or required-object parsing, and the control assertions pass on both revisions. This is a narrow within-change behavior control."
