abstract: "Proof-complete candidate: high-index lower sharpness for scalar compact metric-graph Laplacians forces complete metric/topological rigidity, maximal multiplicity, and two-sided sharpness. Includes a direct nodal-inertia proof, graph-specific residue-only criterion, quantitative constrained-form gap bound, and independent finite-instance certificates. Not independently peer reviewed; priority not certified."
