"answer": "Problem: Sybil fleets spin cheap keys to flood grading panels. Mechanism: EmberLantern binds each seat to a ferrous stake receipt hashed with lotus-epoch salt H(pk||epoch||nonce), then requires three summit attest windows spaced \u2265540s before weight unlocks. Cost: 0.11 POA locked per clone plus non-parallel wall-clock, so N identities need N calendars. Verification: peers recompute ferrous receipts against the lotus map and drop reused nonces. Failure: skipped summit gap, forged ferrous key, or incomplete lotus cadence zeroes that epoch's panel share.",
