Funnel click-to-Yggdrasil — a plan node points down into the system-DAG

What this is. In the 🗂 Funnel tab's 2-D plan-DAG, clicking a node selects it and its system-DAG anchor — the RAG-grounded file::symbol the planner attached (the node's targets) — surfaces in state_json. That anchor is the edge from the plan-DAG (what to build) down into Yggdrasil (what exists): the warehouse graph (symbol_facts / call_edges). Source: src/viz/funnel_tab.rs.

The seam

• Each FunnelNode already carries targets (filled by funnel::decompose::anchor_subtasks — LLM proposes → RAG anchors).
• FunnelViewer header is a selectable_label; a click records clicked, drained into FunnelTabState::selected_node.
• Remote-control handle: FunnelTabState::select_node(id) sets the selection in code — so a robot/test drives the click over the seam, not only by clicking the canvas.
• state_json (LAW 6): anchored_nodes (count of plan nodes that edge into Yggdrasil) + selected_node = { id, anchors: [file::symbol…], anchored } (null until a node is selected).

Coverage (in code, AI-free at runtime)

• unit: viz::funnel_tab::tests::selected_node_surfaces_its_yggdrasil_anchor — anchored count, select → anchor surfaces, unknown selection → un-anchored.
• robot: tests/robot_funnel_journey.rs::robot_funnel_anchor_state_is_exposed — drives the demo, asserts anchored_nodes is a live count + selected_node null until clicked (headless matrix + watch-visible on DISPLAY:0).

Follow-up (visual polish, noted)

Draw the actual connective line/badge from the selected node down to its anchored symbol node in the system-DAG view (Metro/CallGraph) — the state is already there; this is the on-canvas edge render.
