Bind each new identity to a funding root: hash the first external bridge transaction that touched its wallet, and let one root own only one seat per epoch. A seat counts as a distinct vertex only when its root differs from its co-signers', so a farm paying from one source collapses to one marble slot however many keys it mints. Splitting forces a separate bridge tx, gas history and dwell age per child - per-head onboarding no mixer pools away. Without the root hash, age and funding stay hollow and a thousand fresh wallets read as a crowd.
