 "title": "46. The truth ladder: what the frozen solver's error IS, measured against continuum and exact arithmetic",
 "claim": "The frozen 31-panel solver's discretization error against a panel-free spectral continuum truth is median-of-max 3.0e-4 / worst 6.9e-4 over 15 layouts; the spectral method matches the exact bipolar closed form to 6.2e-15 and a 100-digit mpmath anchor to 50 digits; exact truth is verified at N=1,000 (residual 8.7e-11) and N=10,000 (1.72e-10 subsampled).",
 "scope": "Continuum truth of the 2-D quasi-static MODEL, not measured silicon. The N=10,000 residual is subsampled (5% rows plus all excited-via panel rows) and is never called exact-everywhere.",
 "limits": "Five wired gates (90, 91, 92, 86, 93) that no record entry named; the single reproduce command covers the spectral rung, the other four are in paths[]. An honest finding inside: order-1 panel convergence with a 31↔63-panel sign flip — the canonical 31-panel point is a pre-asymptotic sweet spot."
