- A transport exception in the poll loop killed the thread silently, leaving the GUI on a frozen 'Connected' dashboard and blocking run_oneoff callers for the full timeout. _loop now catches it -> stops, fails pending one-offs with the real error, and calls an on_error callback. Controller wires on_error to flag the connection dead; the GUI detects it in _tick and tears down with a 'Connection lost' dialog. - A run_oneoff that timed out left its job queued, so it executed LATER on the shared link -- a ghost/duplicate vehicle command. Jobs now carry cancelled/started flags under a lock; on timeout a not-yet-started job is cancelled (skipped by _drain_oneoffs), and a started one reports 'still running -- do NOT retry'. stop() also frees stranded submitters. - tests/test_scheduler.py: cancel-on-timeout, freed-on-death, loop-survives.
