 "headline": [
  "The lab checked its fast predictor of electrical coupling between vertical metal connections in a chip package against two outside physics programs it did not write, and on every sampled set of layouts the predictor came closer to those programs than the usual add-it-up-pair-by-pair shortcut"
 ],
 "qualification": [
  "for the charge-storage (capacitance) part of the coupling only, and only for the predictor's mutual-coupling numbers"
 ],
 "why": [
  "Without outside solvers, every accuracy figure for the lab's coupling predictor is graded by software the lab wrote itself, which a buyer's reviewer cannot treat as independent."
 ],
 "buyer": [
  "makers of fast chip-package and interposer extraction tools (electronic design automation vendors) and package signal-integrity teams."

 "claim": "Against FastCap 3D-BEM and Palace 3D-FEM ELECTROSTATICS — solvers Genesis does not own — the many-body operator beats pairwise superposition on every sampled population measured, and the two anchors' disagreement about absolute BEM accuracy is decomposed rather than reconciled away. The anchored quantity is CAPACITANCE only: inductance stays the owned 2-D BEM because the FastHenry multi-via deck returns a non-finite matrix, so the truth here is electrostatic-plus-owned-inductance hybrid, not a full-wave anchor. Each population and the reconciliation carries its own command.",
