# Dev-tooling configuration for the rig transpiler (mypy / pytest / coverage).
# rigc is not a python distribution and this declares no [project] table -- it
# exists only so the three tools have settings.
#
# It lives HERE, under scripts/rigc/, rather than at the repository root, for
# the same reason check.sh sits beside it: the transpiler brings its own dev
# tooling and should not plant a root pyproject.toml on a repository that has
# none and expresses its lint settings in .ruff.toml instead. Every tool is
# pointed at this file explicitly by check.sh (--config-file / -c / --rcfile),
# so nothing depends on config discovery finding it.
#
# Ruff is deliberately absent: the repository's own .ruff.toml governs this
# tree like any other, which is the point.
