Iteration 2 of cycle 0026 (graph render redesign). `aura graph` no longer emits ASCII: it now prints one self-contained `.html` to stdout — the ported prototype pin-graph viewer (drill / inline-expand / styled tooltips / breadcrumb) driven by the deterministic model serializer that shipped in iteration 1, with layout and SVG done in-browser by Graphviz compiled to WebAssembly. Closes the redesign opened by spec 0026; unblocked by cycle 0027 (input ports are now named, so the viewer labels every input pin from the model's real names instead of inventing "a"/"b"). What ships: - crates/aura-cli/assets/: the ported graph-viewer.js (prototype genDot/chrome verbatim + a normalizeModel adapter mapping aura's real model tuple shape — ins = [kind, firing, name], index node keys, `comp` refs, `src_<role>` — into the viewer's native shape), plus the vendored Graphviz-WASM (@viz-js/viz@3.7.0) and svg-pan-zoom@3.6.1 blobs and a refresh-assets.sh provenance script. - crates/aura-cli/src/render.rs: render_html(&Composite) -> String, a read-only (C9) assembly — model_to_json + include_str! of the inlined assets, no eval, no build, no serde (C14). The `["graph"]` arm calls it. - Retired: the ascii-dag adapter (graph.rs), the `ascii-dag` dependency, the `--compiled`/`--macd` graph flag plumbing, render_compiled, the color/terminal plumbing, and the 12 ascii-dag-asserting tests + the now-orphaned helpers. The cli_run integration test now pins the HTML page envelope. - crates/aura-core/src/node.rs: the two last ascii-dag prose justifications re-grounded (single-line label rule kept, re-justified generically; the param-generic rule re-justified on C23, not on a renderer limitation). - docs/design/INDEX.md: the cycle-0026 C9 realization note (both iterations). Vendoring decision (spec deferred it to the plan): the WASM/JS blobs are checked in, not fetched at build time. include_str! needs them at compile time, and a build-time unpkg fetch would make the build non-hermetic/non-offline and let the shipped artifact drift with the registry — against C1 (determinism) and C8 (frozen artifacts). ~1.4 MB is the price of a hermetic, frozen render asset. Three adaptations beyond the plan, each verified: (1) render.rs imports `aura_engine::Composite` (the path model_to_json takes), not aura_core; (2) macd_blueprint is now test-only — removing the `--macd` arm left it used solely by the param-space test, so it took `#[cfg(test)]` rather than removal or an `#[allow]` suppression (the production `aura run --macd` path is intact, verified emitting JSON); (3) the `grep ascii-dag` over crates/ matches only the new contract test, which names the term deliberately to document the retirement — no stale justification prose remains. Invariants held (verified independently, not on agent report): C9 (render path read-only), C10 (viewer is a render asset, no logic/DSL), C4 (four-colour palette = the four scalar base types), C14 (no serde). The iteration-1 model byte golden is unchanged and green. cargo build --workspace: 0 errors. cargo test --workspace: 157 passed, 0 failed (incl. the two new HTML tests + the unchanged model_golden). cargo clippy --workspace --all-targets -- -D warnings: clean. ascii-dag absent from `cargo tree -p aura-cli`. closes #51
