What would have stopped it all controls for this way in

• Validators or signers are independent operators; no organisation holds enough keys to sign alone.
  Check: The signer set with each operator named; the threshold is above what any one operator controls.
• Freeze contacts on both chains are arranged in advance: issuers, exchanges, SEAL 911.
  Check: A contact sheet per chain, confirmed this quarter.
