Combinatorics / CONCEPT

Double-star grafting on arbitrary finite graphs

Authority boundary

Dependency edges, status, and source coordinates come from the verified release and certified topology. Blueprint exposition is labeled separately. A fallback title carries no additional mathematical authority.
