A clustering system C is the hardwired clustering system of a rooted level-k network if and only if μ(B) ≤ k for every non-trivial block B in the Hasse diagram H[C].

Introduces LCA-based i-regularization for DAGs that preserves LCAs of small leaf sets, produces regular graphs isomorphic to Hasse diagrams of lca-clusters, and characterizes its relation to normalization.
Global lca-DAGs are characterized via join semi-lattices and forbidden topological minors, with a polynomial-time recognition algorithm.
