		# Rector 2.4+ ships a scoped polyfill at
		# vendor/rector/rector/vendor/symfony/polyfill-php84/Resources/RoundingMode.php
		# that registers a global `class RoundingMode` with string constants
		# (e.g. HalfAwayFromZero = 'halfawayfromzero') via class_alias. PHPStan's
		# Better Reflection walks vendor recursively and binds `\RoundingMode` to
		# that class instead of our enum polyfill in lib/RoundingMode.php, so
		# references to `\RoundingMode::HalfAwayFromZero` are typed as string
		# rather than as an enum case. At runtime the enum in lib/RoundingMode.php
		# wins because it is loaded via composer files autoload before Rector's
		# autoload has any chance to run for the global name (and our tests
		# confirm the enum is the one in use). These errors are purely a
		# static-analysis artifact. See https://github.com/nanasess/bcmath-polyfill/issues/56
