It'd be worth considering a failover mechanism that incorporates state root verification against mithril. Essentially, if 2 out of 3 clients can agree on and validate the state root through mithril, then the failover can proceed with confidence. This creates a more robust consensus layer—clients cross-verify critical state data before executing any transition, which adds an extra security checkpoint. The redundancy ensures no single client failure jeopardizes the system's integrity.
