This concept expands the eight major mitochondrial hubs into a second layer of mechanism, measurement, intervention, and modifier nodes so the map grows in a structured way instead of becoming a flat, crowded network.
Keep the eight major nodes as stable anchors so the larger system remains legible even as we deepen each pathway.
Each hub gets a balanced mix of mechanism, measurement, intervention, and modifier children rather than one undifferentiated list.
Only the most meaningful cross-hub child links are shown, which keeps the design evidence-friendly and easier to expand later.
