Close #49 and remove the last two render special-cases the blueprint root still carried, both pre-0024 vestiges. Since cycle 0024 the root is an ordinary Composite with input_roles, so the render no longer needs to treat it apart: (A) Fan-in slot stubs at the root. A composite-interior multi-input leaf already renders its wired slots as #… stubs; a top-level leaf did not, because render_blueprint threaded stub_ctx: None. It now passes the root composite (it IS a &Composite, carrying roles + edges), and stub_ctx drops its Option — both render_graph callers pass &Composite. The existing slot_source/ fan_in_identifiers/signature_of serve a top-level leaf verbatim; no second stub path (#49 acceptance). SimBroker now renders [SimBroker(#E,#price)] (#E = the Exposure producer's sibling-unique signature prefix, #price = the price source role name). (B) Role-named root entries. render_blueprint built entry markers from format!("source:{kind}") while render_definition uses role.name — the marker/stub asymmetry. The root now builds entries from role.name (filtered to bound roles, source.is_some()), identical to the interior, so the source marker reads [price] and matches the #price slot stub it feeds. render_compilat is deliberately untouched: post-inline the role name has dissolved (C23), so the compiled view keeps [source:F64] from the flat SourceSpec.kind — [price] pre-inline / [source:F64] post-inline is C23 made visible, and compiled_view_golden is the byte-unchanged negative control. Design call (orchestrator, with the user): the marker/stub asymmetry was fixed at its source (the entry naming) rather than by special-casing the stub to match the kind-named marker — the latter would have been a root-only stub behaviour, violating the "no second stub path" acceptance. The user chose full symmetry ([price], dropping the kind annotation) over a name+kind marker, prioritising structural cleanliness; the only remaining root-vs-interior distinction is the bound-role filter (C3), which is semantic, not cosmetic. Scope: crates/aura-cli/src/graph.rs only; read-only render (C9), behaviour-preserving for the run path (C1), no engine change. blueprint_view_golden re-captured from the live `aura graph` output (the where: section stays byte-identical — only the main graph re-flows); the SimBroker needle, a root-SimBroker-stub assertion on the macd view, and a [src] role-name-passthrough assertion are added. Verification (orchestrator-run, not agent-reported): cargo build --workspace green; cargo test --workspace 150 passed / 0 failed (same count, no run-path test moved); cargo clippy --workspace --all-targets -D warnings clean. compiled_view_golden and render_compilat byte-untouched. closes #49
