- Refactor boolean expressions and improve code readability across multiple files - Simplified boolean expressions by removing unnecessary comparisons to true/false. - Replaced explicit boolean checks with direct variable usage Used flags: readability-static-accessed-through-instance readability-simplify-boolean-expr performance-for-range-copy performance-move-const-arg misc-unused-parameters misc-redundant-expression
