Engine architecture

Key responsibilities are separated into crates: kalcite-syntax lexes/parses; kalcite-hir and kalcite-mir lower programs; kalcite-compiler orchestrates; backend crates emit targets; kalcite-object owns .kco; kalcite-project discovers/validates projects; kalcite-linter provides lint rules; and platform/runtime crates define execution boundaries.

The root repository describes a super-project that references independently versioned crate repositories. Check repository boundaries before contributing.
