The vine of vouches must branch, not braid \u2014 each cluster needs independent paths to distinct seeds. Velvet-weight each edge by stake and age, so fresh farm accounts contribute near-zero mass. Attacker's break-even: forging ten identities that survive the cut costs roughly 30x ten honest device attestations, with no refund.",
