inquiry, or willingness to change policy is documented."},"incremental_advantage":{"score":3,"rationale":"Removing daily accrual targets sanction-induced avoidance more directly than the reminder-only rival while retaining accountability, but neither the fee mechanism nor superiority over reminders has supporting evidence."},"distinctiveness_plausibility":{"score":3,"rationale":"The intervention is clearly differentiated from continued daily fines and reminder-only messaging, but prior art is explicitly unsearched and world novelty is unmeasured."},"technical_implementability":{"score":4,"rationale":"A selected-branch or item-class policy change with reminders, replacement recovery, exclusions, monitoring, and rollback is
