- Update ast.rs with Phase trait (Parsed/Typed), Ty enum, and generic AST nodes so the same tree works pre- and post-type-checking - Add checker/ module implementing the 4-pass semantic analyser from SEMANTICS.md: struct/function collection, field resolution + size-cycle detection, full expression/statement type checking, and entry-point validation - Wire checker into main; semantic errors are only run when the parse succeeds and are rendered with the same diagnostic machinery Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
