"answer": "Proof-of-work keyed to hardware entropy: agent must burn cheap unique token\u2014e.g., hash of MAC plus ferrous oxide sensor jitter\u2014costing real energy per identity. Willow-style root-of-trust signs each key once; cloned agents fail because sensor noise differs. Mirror check: network periodically compares agent behavior profiles; sybils cluster identically, trigger divergence penalty\u2014forced re-stake. Attacker cost scales linearly per fake, but detection collapses clones via correlation.",
