lab.VERSION, lab.GAME (.local/minecraft/<version>) and lab.RESOURCES (.local/horizon-client/<version>) come from the lock, and lab.version_info() reads the pinned client jar's version.json. Every harness, generator and tool that named 26.3 (resource folders, jar and source paths, result records, the vanilla client's --version and asset index, the bare login client's protocol, the benchmark's options.txt data version, the packet id table's header) uses them, so a candidate worktree pinned to another version runs them unchanged.
