# README Diagrams Review

## Scope

- Issue: #43
- Milestone: 0.2.0
- Changed surface: root README, localized README, crate README files, README diagram assets, and CI pull request trigger.

## 7-Tier Review

| Tier | Result | Evidence |
| --- | --- | --- |
| Workflow scope | Pass | README and diagram work is isolated from the #42 async code split. |
| Source truth | Pass | Cargo workspace and crate `lib.rs` files were read before generating diagrams. |
| Graphviz layout | Pass | Every diagram has `.dot`, `.plain`, `.graphviz.svg`, and `.graphviz.png` evidence under `docs/images/readme-diagrams/`. |
| Rendered assets | Pass | Every README PNG has a matching decorated SVG source and a Graphviz-rendered PNG evidence file. |
| Decorator baseline | Pass | Final SVG/PNG assets use a compact bluetape4k-style outer frame, title/subtitle header, inner body panel, pastel cards with shadows, and footer callout. |
| README embeds | Pass | README files embed `.png` assets only. |
| CI trigger | Pass | `pull_request.paths-ignore` was removed so PR CI runs for docs-only changes, matching the bluetape-go PR trigger shape. |
| Visual review | Pass | Compact decorated contact sheet plus workspace and core PNGs were inspected; no blank, clipped, imbalanced margin, or overlapping primary content was found. |
| Risk | Low | Documentation-only change with no Rust source changes. |

## Findings

- P0: 0
- P1: 0
- P2: 0
- P3: 0

## Validation

- Pass: `dot -Tplain` for every committed `.dot` file, with empty stderr.
- Pass: README image references point to committed `.png` files.
- Pass: every `.png` has a matching `.svg`.
- Pass: committed SVG files do not contain `Inter`, `Arial`, `Helvetica`, or stale arrowhead marker sizes.
- Pass: compact final SVGs keep the Graphviz-derived node/route topology while simplifying final connector paths for README readability.
- Pass: `cargo fmt --all --check`
- Pass: `cargo test --workspace --all-features --locked`
- Pass: `cargo clippy --workspace --all-targets --all-features --locked -- -D warnings`
- Pass: `RUSTDOCFLAGS="-D warnings" cargo doc --workspace --no-deps --locked`
- Pass: `actionlint .github/workflows/ci.yml`
- Pass: `git diff --check`
