The withdrawal last iteration was caused by `rm -f /tmp/xenia-canary.lock` -- the obvious way past a lock orphaned by kill -9, which also disables the guard for every later launch. Three instances ended up live at once, sharing /tmp/xenia_pad.txt and display :98, and silently confounded an input experiment. Care is not a fix, so this is tooling. ensure_single_emulator.sh counts live instances, stops them (plain kill, then -9, each with a bounded wait), verifies ZERO, and only then removes the lock -- refusing loudly if any remain. The lock is never removed before the condition it guards against is verified absent. FOUR scripts did the bare `rm -f`, and only two were mine from today: menu_loop_session.sh, title_draw_capture.sh, poke_control.sh and resume_reliability.sh. So the footgun was corpus-wide rather than introduced this session. All four now route through the guard. The guard is controlled rather than assumed: run against a deliberately started live instance it reports "1 instance(s) live -- stopping them", ends at 0 with the lock cleared, and exits 0. A guard that only ever passes on an already-clean slate would prove nothing. It also kills by process NAME. `pkill -f xenia_canary` matches the shell running it -- that has now cost this corpus three commands, one of them a cleanup that died halfway and left the very instances it was meant to remove.
