Dos daemons compartiendo el mismo config.toml corren sobre el mismo agentId/agentHash/streamSecret y corrompen el estado de sync del otro. flock advisory en <configDir>/unarr.lock al arrancar: el 2º start se niega con mensaje claro. El kernel suelta el lock al morir el proceso (incluido SIGKILL) → sin problema de lock obsoleto. Scope = config dir, no máquina: un UNARR_CONFIG_DIR distinto (p.ej. el agente dev) tiene su propio lock y corre en paralelo. No bloquea una 2ª instalación con config separada — solo el cross-talk de config compartida.
