Everest is the primary mod loader and modding framework for the game Celeste. It is a standalone platform rather than a simple script loader: the MiniInstaller patches the game's .NET assemblies at install time using MonoMod, manages native libraries across Windows/Linux/macOS, and provides a full mod SDK. The core project is Celeste.Mod.mm, which contains MonoModRules (build-time patching logic), the Everest runtime (mod loading, dependency resolution, event dispatch), the Everest.Content asset pipeline (crawl/process/apply for textures, maps, dialog), and the Everest.Updater self-update system. Mods interact with the game through a clean event-based hook API (Everest.Events) and registries (e.g., StrawberryRegistry) rather than direct assembly patching. The repository is purely an application/framework; there is no data science, ML, or analytics content. The only data-like artifacts are TAS replay files used for CI validation, not for model training or analysis.
