- Variable assignments in match arm conditions (e.g. `is_dir($baseDir = ...)`) were lost after commit 3beb8c6 replaced processExprNode with filterByTruthyValue - filterByTruthyValue only narrows types without walking the AST, so assignments within condition expressions were not discovered for the arm body scope - Fix transfers newly-defined variables from the condition processing scope to the body scope after applying truthiness filtering - New regression test in tests/PHPStan/Rules/Variables/data/bug-13981.php Closes phpstan/phpstan#13981
