PHP Lint (8.2) failed after the floatval removal surfaced a deeper issue: the autoloader references PR_CORE_PLUGIN_DIR unconditionally, which is defined in the main plugin bootstrap but not loaded by the test runner. Same for trailingslashit (a WP function the autoloader calls). Added constants and a tiny trailingslashit stub to tests/bootstrap.php so plain-php unit runs can load the autoloader and exercise the CPT class. No runtime behavior change — test harness only.
