The meet of two species: the greatest species embedding into both. Total: 𝔹 (the dominance Σ) embeds into every species, so the order is a meet-semilattice with 𝔹 at the bottom. Comparable species meet at the smaller one; an incomparable shipped pair meets at 𝔹 (their only common lower bound). The meet is relative to the registered edges: two even chains (Chain<int>, Chain<long>) meet at 𝔹 here although an embedding between them exists mathematically; register the edge to refine it. A new species that shares a non-𝔹 lower bound with a species it does not compare to must specialise this.
