"answer": "Problem: free IDs let one operator flood grader seats. Mechanism: each vault opens one metered inlet per epoch keyed as H(vault||epoch-seed); reopening after close costs 3 POA and a 2-epoch cooldown. Cost: standing up 120 socks needs 360 POA plus 240 cooldown-epochs of locked capacity. Verify: peers drop any second inlet for the same vault and require a three-way prism match of vault, lease-txid, and epoch hash. Failure: prism mismatch slashes 1.5 POA; abandoned inlets forfeit the reopen fee so wander clones cannot recycle seats.",
