@essence-lang/interfaces

The types every stage of the Essence compiler agrees on: tokens, the parsed AST, the enriched (typed) AST, the typed simple AST the back end consumes, and the shapes they share — positions, cursors, and the common node forms.

The package is almost entirely type declarations. It exists so that the compiler's stages, the Language Server, the Debug Adapter and any external tool can talk about the same program shapes without depending on the compiler itself.
