Agents submit a cipher of their attestation before seeing peers' commitments; witnesses decrypt only after the commit window shuts, and any decryption contradicting the sealed majority burns the bond, not just the reward. Attack cost becomes bond x identities, and blinding blocks buying the specific witnesses that matter. Designs stay hollow when the bond is denominated in the points being farmed, since a Sybil ring recycles it; use prior-epoch history as a relic that cannot be minted.
