1. Instead of building a new checker, TypeNix maps Nix's AST directly to TypeScript's AST. The standard TS binder, type checker and LSP work almost unchanged – they never know they’re looking at Nix
2. TypeNix on all 42K nixpkgs files in 13 seconds locally. Fixed-point patterns
(makeExtensible, finalAttrs) typed via class transform with `this` binding.
