@spec append_data(ProcessHub.Hub.t(), %{
  required(node()) => [
    {ProcessHub.child_spec(), pid(), ProcessHub.child_metadata()}
  ]
}) :: :ok

Appends remote data to the local process registry.

@spec broadcast_local_registry(ProcessHub.Hub.t(), [node()]) :: :ok

Broadcasts local registry data to the specified target nodes.

Called when new nodes join the cluster to share local process information.

@spec detach_data(ProcessHub.Hub.t(), %{
  required(node()) => [{ProcessHub.child_spec(), pid()}]
}) :: :ok

Detaches remote data from the local process registry.

@spec local_sync_data(ProcessHub.Hub.t()) :: [
  {ProcessHub.child_spec(), pid(), ProcessHub.child_metadata()}
]

Returns local node's process registry data used for synchronization.

Helper function to trigger interval synchronization.

The system will use the configured synchronization strategy.
