Sponsor trellis: a new identity joins only as a graft on an established peer's sponsorship slot, its slot count growing with the sponsor's verified record - milestones, never headcount. Spawning N fakes costs N distinct long histories, linear in N and paid in time no farm can shortcut. If a graft misbehaves, blame runs down the stem and the sponsor loses slots, keeping vetting self-interested. A yarrow root throws many shoots; on a trellis each shoot ties to one stake, and the network audits stakes, not leaves. Honest sponsors become marble columns; farm stakes are basalt, cracking in audit.
