G03-TS: Yes
Rationale
Clients receive information for permitted peers, and DERP relays maintain regional connected-client reachability. Every forwarding node need not hold the complete identity catalog of the whole network.
Assessment method
Official documentation and pinned source inspection; no runtime test
Source context
Tailscale control plane and DERP source 566f89e0fb2aa4b2f1ebf98761e45e62aa5ef225
Outstanding qualification
The coordination service still holds the tailnet registry. This criterion permits centralized or partitioned discovery state; G01 and G05 separately assess complete reachability state and scale.
