demo.sh loaded (and jumped) the payload before it ever looked at --tiles, so a wrong path -- the frames directory rather than the cache make_tiles.py writes -- only surfaced after the machine had been handed to a payload that never returns, forcing a reboot to retry. It now checks dictionary.bin/stream.bin first, names the frames-vs-cache confusion when the directory holds raw frames, and exits 2 without touching the network. The README's failure table gains that row and the --no-load recovery for an instance that has already been jumped.
