Tracks are now first-class Problem objects (TrackSeg: centerline + width, dump schema v5), so the wide/narrow decision replays at raster time: traces at least TRACK_1D_FACTOR (3) cells wide rasterize from their outline as before; narrower ones mark the cells their centerline crosses as copper and connect them with explicit conductance links carrying the trace's TRUE arc length per link - no staircase inflation for diagonals or arcs, and no discretization error in the trace R, at any grid size. Links across cells already joined by pour faces are skipped (union, not sum); chain-only cells get no sheet faces (their copper is narrower than a cell). Electrodes, via barrels, connectivity restriction and the skin-effect scaling all work on chain cells unchanged. This removes the need to shrink the cell size for thin traces: a 0.2 mm bridge at 500 um cells now matches its finely-rasterized ground truth within a few percent (tested), including diagonal and arc traces.

"description_full": "Computes the DC or AC resistance of copper zone fills and traces between two contacts (marker rectangles on User.1/User.2 and/or selected pads), single- or multi-layer: the chosen net's fills and tracks are solved as coupled finite-difference sheets linked by the net's via and through-hole-pad barrels; traces narrower than the grid become exact 1D resistor chains.\n\nShows per-layer rasterized maps, potential, current density and power density, reports per-via currents (via ampacity) and total dissipation at a selectable test current. At a user-set frequency the exact 1D foil/barrel skin-effect correction is applied (AC results are a rigorous lower bound). PNGs, a text summary and a re-solvable geometry dump are saved per run.\n\nNote: the first load builds the plugin's Python environment (numpy, scipy, pyamg, matplotlib, PySide6) and can take several minutes.",
