Each dot is a relay node. Size = wealth. Color = rent share of income: green earns competitively (bread), red earns from position (shields). Halo thickness = neff of independent alternatives — thick means contestable, thin means choke point.
Hover a node to see the counterfactual shadow: dashed paths its dependents would take if it vanished, labeled with the premium. Cyan pulses are bypass audits actually exercising those paths.
The tax has a threshold: below a marginal rate of ~1 on scarcity-rent it merely transfers (revenue high, behavior unchanged); above it, it disciplines — hubs learn markups down and revenue self-extinguishes. Try sweeping the tax slider through 1.0, and try the Sybil scenario with estimator quality at 0.
