Horizon no longer fetches anything of Minecraft from Mojang's servers. The client jar, version JSON, libraries and assets come from the user's official launcher install, and the server jar is one they downloaded themselves (--server-jar or HORIZON_SERVER_JAR). Every file is checked against checksums pinned in research-lock.json, and the prepared .local/ layout is byte-identical to the old downloads, so the harnesses and the native client are unchanged. CI keeps the offline checks on GitHub's runners; the vanilla comparisons and the mod build need the game, so they move to a manual job on a self-hosted runner that holds the maintainer's own copy.
