Three independent failure modes that each end with a dark panel and no automatic recovery. 1. PluginHealthTracker._load_health_state returned the cached value verbatim. If that value is not a dict, every caller raises AttributeError: 'list' object has no attribute 'get' — during DisplayController.__init__, so the process dies before the display loop starts. systemd restarts it, the same bad entry is read back from disk, and it dies again: an unattended restart loop that survives reboots because the cause is persisted. Observed in the field with plugin_health:<id> holding an unrelated plugin's list payload. Now non-dict entries are discarded with a warning and the defaults are rebuilt. 2. ledmatrix.service used Restart=on-failure, so any exit with status 0 left the unit stopped and the panel dark indefinitely — systemd treats it as success and never brings it back. Restart=always. 3. ledmatrix-wifi-monitor.service used StandardOutput=syslog, which systemd has marked obsolete; it warns and rewrites it to journal on every load.
