Recommend the exact engine for KiCad boards; document --edge-clearance,
--grid-resolution, --heuristic-weight and the unrouted report; list what is
read from a KiCad DSN (pads, vias, keepout kinds, outline, zones, fine
pitch), each checked against KiCad; replace the scope section with the
TerraHawk measurements and what still trails the JAR.
Add the GPLv3 text (the package declared the licence but never shipped it),
a py.typed marker, and an sdist include/exclude allowlist so the distribution
carries only src/, docs/, README, LICENSE and pyproject. reference/ is a clone
of the GPL FreeRouting Java tree kept purely as a porting reference and must
never be redistributed inside this package; tests, caches and build output are
excluded too.
Switch to the PEP 639 SPDX licence expression with license-files, widen the
classifiers, and add an -o alias for -do. Rewrite the README around the engine
matrix: what each track and pass actually does, and what this is not (no
FreeRouting density parity on dense boards, and --diagonal is a recovery and
shortening pass, not a diagonal-native search).
Pure-Python PCB autorouter replacing the freerouting.jar step in kicad-mcp.
Contract is Specctra DSN in, SES out — a drop-in for the JAR so the toolchain
needs no JVM. Includes pyproject (uv/ruff/pytest, src-layout) and a porting
plan seeded for study of the upstream FreeRouting Java source.
