Percolation / Tipping Points
Sparse links suddenly gel into a giant component — bank networks and blackouts tip fast.
How it works
- Add random links; clusters merge slowly, then one giant component snaps into being.
- The snap point is the tipping threshold.
- Just past it, shocks travel everywhere at once.
Use → Fragility audits, buffers, circuit breakers.
Watch out → Linear extrapolation through a threshold — 'a bit more' becomes 'everything'.
Try it → Keep a checklist of buffers whenever connectivity passes ~50%.
