  "falsification_rule": "Claim a question-directed restricted-port advantage only if active probes beat BOTH fixed question-independent routes and equally budgeted addressable direct-phase probes on held-out queries on both frozen checkpoints. Order sensitivity requires a separate superiority versus same-budget reversed order and raw paired-order controls. Do not confuse target routing with a commutator information gain.",
  "limits": "Only static four-mark synthetic scenes; 2 fixed complex ports; preplanned question-dependent routes, not feedback-adaptive or PDE wavefront propagation. The direct phase and amplitude arms have stronger addressable access than fixed port arms."
