    "The optimum verifies at the declared coarse plan but the contract-9.4 refined 10-station plan does not re-verify it (arc_60 tape-edge node the coarse plan never sampled; refined capacity 1249.3 A still exceeds I_op 977.8 A \u2014 the edge self-field regime OC-014 targets, resolvable to a real verdict under schema v5). The headline length is therefore a coarse-plan optimum, not a fully verified design."
