fill_resistance/quadtree.py decomposes a layer's fine copper mask into
2:1-balanced power-of-two leaves: boundary and keep-fine cells stay at
the fine size, interiors coarsen with their Chebyshev distance to the
nearest feature (guard factor, default 4), and an explicit enforcement
pass splits any leaf more than twice an edge-adjacent neighbor. Face
conductances use the series-half-cell rule, which reduces to the
production harmonic mean for equal sizes and EXACTLY to sigma in the
uniform limit - verified edge-for-edge against solver.build_edges and
to rel 1e-12 in R against run_solve, so the exact-value test suite
stays authoritative for this engine.
Measured (feature-dense 120x120 plate, h=50um, production AMG solver):
uniform 5.58M unknowns ~35s; adaptive guard=4 823k / ~8s at -1.1%;
guard=8 1.74M / ~12s at -0.47%. tools/adaptive_proto.py now benchmarks
the engine itself.
Not yet wired into the pipeline: phase 2 ports electrodes, barrels,
1D chains, buildup and field output onto leaves.

Proves the design for true adaptive cell sizes: bottom-up coarsening of
the existing fine raster into power-of-two leaves (erosion-graded),
vectorized leaf-graph construction whose uniform limit reproduces the
production grid exactly (rel diff 0), solved with the production
assembly + AMG. On an adversarial 5.6M-cell geometry: 12x fewer
unknowns at -0.42% R (27 s -> 3 s) up to 26x at -2.1%.

The previous 24 px icons were a copper square with a tiny knocked-out
ohm that was unreadable in the toolbar. tools/gen_icons.py renders the
glyph supersampled from DejaVu Sans Bold in theme-specific copper
shades (plus the 64 px PCM listing icon).

- Refuse the uniform contact model when the fills form multiple
disconnected copper groups that each touch both terminals: the
prescribed injection split is ill-posed and the grounded system was
singular, silently returning garbage (e.g. negative gigaohms).
connected_restrict now reports the component count; a power-balance
backstop (SolverError) catches any other inconsistent solve.
- Connect via/pad barrels to the nearest fill copper within the pad
footprint (+1 cell) instead of only the exact center cell, so
thermal-relief spokes still stitch layers; barrels that reach fill on
fewer than two layers are warned about. ViaLink gains pad_nm
(extracted from the padstack, JSON-roundtripped).
- Validate dialog input on OK (layers, current > 0, cell > 0, parseable
frequency, extra Cu >= 0) with an inline error instead of silently
substituting defaults; parse_frequency raises on garbage; pipeline
rejects i_test <= 0; choose_cell_size rejects non-positive overrides.
- Warn when a contact part is dropped by the connectivity restriction;
floor instead of truncate in cell_of; correct the uniform-model
summary line; drop an unused variable; refresh plugin.json wording.
