horizon-launcher native-build FOLDER --trust-native-code compiles mixin bundles (a folder with a
horizon-mixin.toml, or an unpacked .hnmod from the registry) into a game of their own:
- the Horizon commit the mods pin (all must agree; else the installed version's), its source from
GitHub by commit (Nightlies keep theirs as nightly-source/ tags);
- horizon-mixins at the commit the mods were tested with, built once with the launcher's Rust;
- horizon-mixins apply, then the release's cargo build, with the portable toolchain;
- installed as native-<commit>-<key>, played by the Native mods instance.
Based on native-mixins-1's unmerged work; docs/native-mods.md describes it.
