* If there's two endpoints, but only us seeing ourselves and the application start is less than 60 seconds in the past, do nothing (wait for cluster reconnect to take place, grace period).
* Sort the collected endpoints by name.
* Iterate over all config types and their respective objects
* Ignore !active objects
* Ignore objects which are !HARunOnce. This means, they can run multiple times in a zone and don't need an authority update.
* If this instance doesn't have a local zone, set authority to true. This is for non-clustered standalone environments where everything belongs to this instance.
* Calculate the object authority based on the connected endpoint names.
* Set the authority (true or false)

Each instance alculates the SDBM hash of the config object name, puts that in contrast
