Do two tokens share a holder base? (coordinated-network signal) — Do two tokens share the same recent holders — the farm / sybil / coordinated-launch signal nobody else surfaces? Reads each token's recent recipients and returns the overlap as a share of the smaller set: independent (the few % unrelated tokens share via routers/power users), overlapping, or strongly_linked (a coordinated cohort — same farm, deployer community, or a sybil set rotating between them). Pass a= and b=. A signal, not proof. Not financial advice. Required inputs: a, b.
