- solve_full: sparse graded-mesh solver with a cell budget that auto-coarsens or raises MeshBudgetExceeded; PEEC assembly guarded. Typical PCB cross-sections solve in under a second within a few percent of reference values. - Rasterizers kept FR-4 Er instead of snapping to the nearest palette material; cache key includes materials. - Coupled microstrip: Kirschning-Jansen even/odd modes, optional solder mask; odd-mode eps_eff now below even-mode. - Stripline: Wheeler models with validity warnings and stated accuracy. - CPWG: never above microstrip, monotonic in gap. - Conductor loss: Pucel with surface resistance and optional roughness; dielectric loss by filling factor (embedded vs bare consistent). - Microstrip eps_eff thickness correction sign fixed.
