- adaptive: barrel links could attach to coarse leaves (up to 1 mm),
making the whole leaf equipotential and deleting the local spreading
resistance - via-field results read up to ~13% low. Barrel attachment
cells are now pinned into the keep-fine set before the quadtree is
built; the guard ring grades around them.
- skin/dialog: the decimal-comma rewrite turned '1,500' into 1.5, a
silent 1000x error in frequency, test current or cell size. Ambiguous
comma patterns (thousands separators, multiple commas, mixed with a
dot) now raise with a message; a real decimal comma ('1,5') still
parses.
- dialog: Selection.adaptive default now matches the documented
on-by-default; the adaptive accuracy claim is aligned to the measured
0.03% quoted in README and config.
