# Per-class category corrections: "FQCN category reason...". Every entry # must carry a reason. Keep this list short; prefer fixing the rules. Composer\Util\Platform rust-proxy env table is shared process state; the child's Platform stub RPCs putEnv/getEnv/clearEnv so both worlds see the same environment Composer\Autoload\ClassLoader php-native the child bootstraps via the real vendor/composer/ClassLoader.php before any stub could load; a same-FQCN stub cannot shadow it. Registered-loader state is per-world. Composer\InstalledVersions php-native same bootstrap constraint as ClassLoader (real file in vendor/composer is always loaded); its static $installed is genuinely shared state — Rust must push a reload after each install dump (see static-state.list needs-sync) Composer\Platform\HhvmDetector php-native stateless environment probe; only reachable as a consumed ctor param of PlatformRepository, no Rust-owned instance is ever provided to plugins. Plugin-custom detectors passed into a proxied PlatformRepository become an explicit error. Composer\Package\Version\VersionGuesser php-native stateless computation over VCS output; only reachable as a consumed ctor param of RootPackageLoader, no Rust-owned instance is ever provided to plugins. Plugin-custom guessers passed into proxied ctors become an explicit error.
