# conformallab++ clang-tidy policy
#
# Curated, deliberately small.  The CGAL header tree triggers tens of
# thousands of warnings under default settings (CGAL's chosen style is
# pre-C++17 in many places).  Restricting to checks that fire on OUR
# code, not on transitive CGAL/Eigen/Boost headers, keeps the signal
# meaningful.
#
# Promotion gate: a check moves into this list only when (a) it fires
# on code we authored AND (b) the fix is mechanical (no algorithmic
# rewrite required).  Anything algorithmic belongs in a code review,
# not in a static analyser.
