# Review report for pipeline/overview.md

## Summary

The overview is well structured and most claims match the recorded source commit, but it still points readers at `slang-emit.cpp` rather than `slang-code-gen.cpp` for the top-level target dispatcher. Its lowering summary also overstates how statements map to IR, and its recorded watched-path digest predates the current resolved watched set. Three minor findings require remediation.

## Items checked

- Verified 17 factual claims across preprocessing, deferred body parsing, semantic checking, AST-to-IR lowering, IR-pass orchestration, emission, and compile-request sequencing at commit `53b76e6d3009b8e6434d41573524c7ce5c499d23`.
- Re-derived all three line-number citations: `linkAndOptimizeIR` at `source/slang/slang-emit.cpp:970`, `emitEntryPointsSourceFromIR` at `source/slang/slang-emit.cpp:2746`, and `checkAllTranslationUnits` at `source/slang/slang-compile-request.cpp:498`.
- Resolved all 41 Markdown links (33 unique targets) at the recorded commit and confirmed all 12 referenced generated peer pages are present in the manifest.
- Swept 29 code identifiers and 18 cited source filenames at the recorded commit; all exist. Also confirmed 162 matching `slang-ir-*.cpp` files.
- Verified all mandatory front-matter keys and recomputed the current resolved watched-path digest as `519fade0f73ddc2f1adb7802668653730b5be442d1722cb8f2c593b47d26d7bb`.
- Checked the required title, flowchart, six stage subsections, driver section, five cross-cutting bullets, 7,837-byte size, and universal style rules.

## Findings

| ID | Severity | Location | Description | Evidence | Recommendation |
| --- | --- | --- | --- | --- | --- |
| F-001 | minor | Front matter, lines 1-7 | The recorded `watched_paths_digest` is stale for the resolved watched set: the page records `c244a601...`, while the current manifest now watches `slang-code-gen.cpp` and recomputes to `519fade0...` at the same source commit. | `docs/generated/design/_meta/manifest.yaml:76-92` includes `source/slang/slang-code-gen.cpp`; `python3 docs/generated/design/_meta/regenerate.py digest pipeline/overview.md` returns `519fade0f73ddc2f1adb7802668653730b5be442d1722cb8f2c593b47d26d7bb`. | Refresh the page front matter through the generation/remediation workflow so `watched_paths_digest` records `519fade0f73ddc2f1adb7802668653730b5be442d1722cb8f2c593b47d26d7bb`. |
| F-002 | minor | `### AST → IR lowering`, lines 92-97 | The statement that “statements become basic blocks with parameters” implies a one-shape lowering that the source contradicts. Control-flow statements may create blocks, but sequence and block statements recursively lower their children, and a return statement emits a return instruction in the current block. | `source/slang/slang-lower-to-ir.cpp:8280-8323` creates blocks for `IfStmt`; `source/slang/slang-lower-to-ir.cpp:8811-8829` recursively lowers sequence/block bodies; `source/slang/slang-lower-to-ir.cpp:8831-8849` emits return instructions. | Change the clause to say that control-flow statements create blocks and branches while ordinary statements emit instructions in the current block; mention block parameters only as the SSA representation for values crossing control-flow edges. |
| F-003 | minor | `### Emit`, lines 124-138; `## Driver entry points`, lines 168-170 | The page correctly names `CodeGenContext::emitEntryPoints` as the per-target selector but omits its defining file from “Driven by” and later calls `slang-emit.cpp` the back-end dispatcher. The top-level and binary/non-source dispatch actually live in `slang-code-gen.cpp`; `slang-emit.cpp` owns IR orchestration and C-like source-emitter selection. | `source/slang/slang-code-gen.cpp:1114-1223` defines `_emitEntryPoints`, and `source/slang/slang-code-gen.cpp:1247-1304` defines `emitEntryPoints`; `source/slang/slang-emit.cpp:2746-2867` defines only `emitEntryPointsSourceFromIR` and its source-emitter switch. | Add a direct `slang-code-gen.cpp` link to the Emit “Driven by” list and driver section, identify it as the target dispatcher, and describe `slang-emit.cpp` as the linked-IR/pass orchestrator and source-emitter selector. |

## No-issues notes

- The three recorded line numbers are exact at the target document’s source commit.
- All relative links resolve at the recorded commit, and every generated peer link names a manifest page.
- The Mermaid diagram uses camelCase node IDs, no explicit styling, and the required left-to-right stage order.
