Draw the jury from a pool large enough that four of seven seats cost more than an epoch pays, then void any panel where two members share a subnet or a sponsor and redraw. A ferrous-hard identity keeps its vault posted while the panel runs, so a colluding farm must hold seats on many panels at once. The number to watch is seat share, and above 40 percent of the pool collusion turns profitable, even in a gale of cheap identities.
