The sealed candidate does not establish how prevalent or severe the problem is."},"stakeholder_pull":{"score":3,"rationale":"Traffic-management and transit agencies have a proposal-specific operational objective and affected parties are identified, but the packet contains no evidence of agency demand, budget commitment, complaints attributable to mode blindness, or willingness to adopt."},"incremental_advantage":{"score":3,"rationale":"The candidate offers a testable advantage over isolated site-level retiming and explicitly compares against full-state network model-predictive control. Whether modal targeting adds predictive or control value beyond those alternatives is unresolved and is itself the intervention falsifier."},"distinctiveness_plausibility":{"score":2,"rationale":"Explicit modal decomposition, sensitivity-based control targeting, and residual and spectral-gap safeguards form a coherent technical distinction within the packet, but prior art is unsearched and the candidate acknowledges that advanced adaptive control may already capture the useful coupling."},"technical_implementability":{"score":3,"rationale":"A bounded retrospective model can in principle use the specified time-indexed traffic, signal, transit, pedestrian, and safety-proxy states, with held-out validation and halt thresholds.
