3The fleet's peer link frames, byte for byte as the Rust writes them (mesh-abi "peer frames v6"):
4`F_JOIN` with this machine's capabilities and the checks that refuse a link (version, cluster size,
5who dials whom), the election and commit messages of `@ajax/mesh-fleet-core` (`F_VOTE_REQ`, `F_VOTE`,
6`F_STATE`, `F_STATE_ACK`, `F_COMMIT`), `F_BEAT` (the core's beat plus the member's reconcile status,
7reason and move outcomes) and `F_HELLO` (a lockstep group member ready for an epoch and cycle).
