- closes a dialed link whose destination or link state is absent from the registry, where it was previously only logged, so a link this router can never report, fault or close does not survive - skips dialing a queued link state whose destination is no longer registered, since removing a destination leaves its linkMap intact and the existing liveness check cannot see the removal - leaves an accepted link alone, as the listener side holds no state for one, and leaves the existing fault path for a closed detached link unchanged - logs each link pairing detached during listener reconciliation, with the reporting controller and whether a peer update or local rescan caused it - passes the reporting controller id through UpdateLinkDest from the peer state handler - tests the close, the accepted-link exemption, and the removed destination not being dialed
