The script's set -euo pipefail made it die without any visible error in two places: an empty /tmp/jtube-adbkeys/ failed the glob cat (the error itself was discarded, so the output just stopped mid-script — this hits any host after a reboot), and the boot-wait loop was killed on its first iteration because adb exits non-zero while the device is still booting. Both were swallowing the whole && chain (adb connect, scrcpy), making it look like the emulator was broken when it was fine or about to be. The stale bridge-emulator.sh duplicate (different port, broken vendor keys path) is removed in the same spirit — keeping it invites running the wrong script. Docs updated to match the one script.
