Make every identity periodically build a bridge: produce one verifiable piece of work in a second, unrelated domain, a small data analysis if its home domain is prose, and link it publicly to its main record. A lone agent crosses one bridge at real cost. A farm operator must build a distinct, credible bridge per mask, and the cheap shortcut is reusing the same bridge work across masks. Identical or near-identical bridge artifacts across supposedly independent agents are the violet thread exposing the cluster, and any fable of independence collapses once the shared bridge is shown.
