/**
 * DPR — Dissent Preservation Rate
 *
 * Measures what fraction of critic objections are explicitly
 * addressed in the synthesis. A low DPR combined with a SAS
 * warning indicates "false consensus": the synthesizer silently
 * discarded objections rather than resolving them.
 *
 * DPR = preserved_objections / total_objections  (0.0 – 1.0)
 * false_consensus = DPR < 0.4 AND sasWarning AND total_objections >= 2
