>     If the master fails over and an agent does not re-register within the
>     `agent_reregister_timeout`, the master marks the agent as unreachable in
>     the registry and sends `slaveLost` for it. However, we neglected to
>     update the master's in-memory state for the newly unreachable agent;
>     this meant that task reconciliation would return incorrect results
>     (until/unless the next master failover).
