# Review report for pipeline/04c-layout-ir.md

## Summary

The layout-IR page matches `TargetProgram::createIRModuleForLayout` and its prompt shape. I found no issues requiring remediation.

## Items checked

- Ran `regenerate.py show pipeline/04c-layout-ir.md` and read the target page, `_common.md`, `pipeline-04c-layout-ir.md`, and dependencies `pipeline/04-ast-to-ir.md`, `pipeline/04b-pre-link-passes.md`, `cross-cutting/targets.md`, and `ir-reference/index.md`.
- Verified front matter keys, recorded source commit, and 64-character hex watched-path digest.
- Checked all source line citations against `source/slang/slang-lower-to-ir.cpp`, `source/slang/slang-target-program.h`, `source/slang/slang-parameter-binding.cpp`, and `source/slang/slang-ir-link.cpp`.
- Spot-checked 18 layout-construction claims including cache behavior, `m_layout` assertion, global-parameter loop, parameter-group layout branch, entry-point skip conditions, import decoration, SPIR-V/Metal capability atom forwarding, optional obfuscation strip/DCE, and final mangled-name-map construction.
- Resolved relative links with `regenerate.py lint` for this assigned doc group; lint reported no issues.

## Findings

(no findings)

## No-issues notes

- The document correctly avoids turning layout-IR construction into a four-phase target-pipeline page.
- The optional obfuscation description matches the `shouldObfuscateCode()` block and strip options.
- The caveat about layout modules participating in `linkIR` is supported by `targetProgram->getExistingIRModuleForLayout()`.
