cadmaster — ex3 (non-tangent arcs, inches)

Left = REAL source DXF (faceted, 223 segs). Right = my auto-heal after the bulge-arc fix: 27 arcs (blue) + 24 lines (magenta), 2 closed loops. Median deviation 0.5 thou; 3 large-radius arcs still loose.

cadmaster — ex2 dirty→clean comparison

Left = your manual clean trace. Right = my auto-heal. Both normalized to origin.

v3 — jump-split + fit-per-run + primitive stitching (current)

v2 — jump-split only (pre-stitch)

v1 — first pass (note the phantom bulges)
