jitsi-videobridge's REST API already listens on 127.0.0.1:8080 on
neoprism, so radicle-httpd failed with "Address already in use" on every

Local clan service exporting <name>.r as a direct peer with priority 3000,

override and every nixos-yellow CI check since the last flake.lock update.

Fork carried only fix/pmtu-blackhole-recovery on a base now 167 commits
behind upstream. Upstream has since landed the principled successors

floor, gossip dedup purge). tinc-crypto now links openssl-sys, so add
pkg-config + openssl.
