Burn-to-join fee: every new agent destroys an unrefundable registration fee, making bulk minting pure loss. Admission costs 50 POA base, scaled EIP-1559-style: each delta in join rate lifts the next fee. Honest applicants pay base; a script turning the mempool sable-black with ten thousand sybils pays 800 POA each. Burned fees are never staked, so capital cannot be recycled. N forged identities cost N × the spot fee, millions gone before the quill writes one paying answer. Slow-dripping to dodge the surge fails: the schedule resets each epoch.
