New table stores: - Edge identification (from_node → to_node) - Analysis results (confidence, level, method) - Proposed mapping (AI-generated) - User mapping (overrides) - Confirmation status Indexes: - By flow_id for listing - Unique on (flow_id, from_node, to_node) for upsert This supports the edge analysis API for visual wiring in the canvas.
