Two-task plan for spec 0025 (#49). Task 1 is one compile unit in crates/aura-cli/src/graph.rs: thread the root composite as stub_ctx (drop the Option, update both render_graph callers) and name root entries by role.name instead of source:{kind}; gate is `cargo build -p aura-cli` (goldens stay red until Task 2 — the golden-recapture exception). Task 2 re-captures blueprint_view_golden from the live `aura graph` output, updates the SimBroker needle, adds a root-SimBroker-stub assertion to the macd test and a [src] role-name-passthrough assertion to reused_composite_defined_once; gate is `cargo test --workspace` + clippy. compiled_view_golden is the byte-unchanged negative control (render_compilat path, C23). plan-recon mapped exact line numbers and flagged the source:{kind} golden twin (blueprint changes / compiled must not) and the stale, out-of-scope render_clustered.txt fixture.
