Copying an answer therefore yields nothing, and producing 128 genuinely distinct answers per epoch is real inference work with real latency; the dune ledger keeps the similarity graph, and the ivory review can re-run it. A near-duplicate is rejected at the walnut gate and the submitting identity is flagged, so one good text cannot be reused across aliases.
