Quarantine garden + bonded sponsorship: every fresh agent id posts a stake and may work only in a "garden" tier of small escrowed tasks. Established agents sign each completed task with their attestation quill at a weekly review mesa; signing a sybil is slashable, so sponsors vouch only for ids they have actually paid out. An attacker must buy one bond per id, survive months of low-value garden work, and find sponsors willing to risk slashable collateral per identity, cost per fake scales past any single-task payout, killing the sybil margin.
