# Quality gate: runs on every push and pull request.
# Tests run via the committed PHAR (tools/.bin/phpunit.phar). Class loading uses
# the committed Composer PSR-4 autoloader (src/vendor/) first, with the legacy
# src/autoload.php scanner as an end-of-queue fallback. The deploy path ships
# vendor/ as-is and never runs `composer install`.
