"validators_disconnect.sh" NCTL test passes correctly with Highway, but fails with Zug

[SaiProServ]

When Zug is enabled, network fails to resume operation after the previously disabled validators are started again

• Determine how much work remains to be done for the protocol state persistence.

Update from Bart in the L1 Daily on 18-Sep-24;

Regarding the persistence of consensus state - what Zug persists isn't really the state, but it should be sufficient for resuming operation AFAICT. For Highway, the effort depends slightly on where we would want to store the state - storage, or some additional files similar to currently used unit files? Storage would be slightly more effort, but with it now being available in other components as an object (and not just through events/effects) it should not be too hard, either.

Action: As outlined by Ed, Bart should describe the state that needs to be persistent and define when it should be persistent. This detailed specification will allow the task to be delegated to other team members for implementation.

@devendran-m Those updates would fit #3904 better than this ticket, I think. This one is about a failing test and likely completely unrelated to the persistence of protocol state.
