Upstream's git HEAD appends serverName to server_installed, but the shipped 1.0.4 client (fabric-26.2) decodes exactly version/lastGen/interval/mode/ ticks and vanilla disconnects the player with "8 bytes extra" on the first hello. Verified with javap on the release jar; the other three codecs match. Drops the server-name option (a leftover key now only warns).
