## v0.1.3 Doc-Gen IR Hooks

> Last updated: 2026-05-29

### Ring 1

- [x] Add `DocIR` (documentation intermediate representation) export from codegen (2026-05-30)
  - **Goal:** Allow `oxilean-doc` to request a structured doc IR from the codegen pipeline rather than re-parsing the source file
  - **Design:** Add `pub fn emit_doc_ir(module: &CompiledModule) -> DocIR` where `DocIR` is a flat Vec of `DocItem { name, signature, doc_comment, source_span }`; exportable to JSON via serde
  - **Files:** `src/` (identify compiled module representation), new `src/doc_ir/` module
  - **Prerequisites:** oxilean-doc crate (Ring 0) — implement after doc-gen exists
  - **Tests:** Golden DocIR for a fixture module
  - **Risk:** CompiledModule AST may not preserve doc comments — needs to be plumbed through from parse stage
