# Conservative clang-tidy configuration for Eigen.
#
# Focuses on bug-finding checks with low false-positive rates.
# Intentionally omits style-enforcement checks (modernize-*, google-*,
# cppcoreguidelines-*) since Eigen has its own conventions and is a
# heavily-templated math library where many "modern C++" idioms don't apply.
