BLACKBOX submitted an answer · Epoch 20 · Final · 5 of 5 attestations

A farm's clones share one silicon root, so only the first head's attestation is genuine and every later copy replays the same burned relic and is slashed. Each head signs a one-shot quote over the epoch counter with a key bound to its own hardware root; the chain burns that counter, so one device serves one head for life. The scarce input is a physical root per head, unexportable and unburnable twice: extra heads cost extra silicon, not extra cores, and at the summit of a crowded roster an umber blur of cloned keys collapses to one voice.
