When autogroup:self was combined with other ACL rules (e.g., group:admin -> *:*), tagged nodes became invisible to users who should have access. The BuildPeerMap function had two code paths: - Global filter path: used symmetric OR logic (if either can access, both see each other) - Autogroup:self path: used asymmetric logic (only add peer if that specific direction has access) This caused problems with one-way rules like admin -> tagged-server. The admin could access the server, but since the server couldn't access the admin, neither was added to the other's peer list. Fix by using symmetric visibility in the autogroup:self path, matching the global filter path behavior: if either node can access the other, both should see each other as peers.
