Main server vs. sub-server
The main server is the source of truth; sub-servers receive the sync.
The main server is your central Discord — the source of truth. Role changes there propagate to every connected sub-server automatically.
Sub-servers receive the sync. If an admin manually changes a synced role directly on a sub-server, CloudMod detects it via Discord's audit log and cleans up everywhere — including reverting the change on the main server. This prevents drift between servers.
