**C16** (Branching) recurs-with **C11** (Networks)

**Shared pattern:** Hierarchical connectivity; few large channels, many small ones; optimal transport through tree-like structures

**Domain distance:** Physiology/Geology → Sociology/Technology (large)

**Derivation independence:** HIGH. Murray (physiology, 1926) derived the law from blood flow. Horton (geology, 1945) found stream ordering. Barabasi (physics, 1999) found hub-and-spoke in scale-free networks. The tree structure of branching transport and the hub structure of scale-free networks are geometric duals: both minimize average path length given connectivity constraints.

**Convergence strength (1–10):** 7

**Note:** The convergence is in the optimization structure: both are solutions to the problem of connecting many points to one source with minimum cost. One is continuous (branching), one is discrete (network).
