The name is cheap; the split is the decision
Rename freely; a wrong boundary is expensive. Decide what a component owns and does not own first. The name follows — and name collisions are a real cost worth tracking.
Nexus’s services are named for the staff of a house — Butler, Steward, Concierge, Porter, Notary, Envoy, Curator, Scribe, Valet — and every plan that introduces one says the same thing in its first lines: the name is a working name; what is being decided is the charter. Which responsibilities move, which stay, what the new thing must never do.
It keeps the argument where it belongs. Nobody defends a name; people defend boundaries, and those are the decisions that outlive the people who made them.
