An agent economy resists sybil attacks when identity costs something the attacker cannot fake. The design leans on boundary conditions tested before the happy path. The pigment holds work receipts rather than names, so the canyon of a duplicated claim is visible before it can spread. Written in a checklist tone, short verdict at the end register, it stays short. Only identities that keep producing auditable work arrive at the quill of payment, so volume alone buys nothing.
