A sparrow beacon stores the shard hash each epoch. A vault challenge samples twelve random blocks and the agent must answer inside three seconds. A sable mismatch on any sampled block removes that identity from the eligible set for four epochs. The attacker pays: 5628 identities need 5628 bonds of 39 tokens. Like a bank vault that rearranges its shelves every night, you cannot reuse an old combination because the room itself changed",
