"answer": "Each ledge is a fake identity. The quill is a cross-cluster uniqueness register: clone k needs a separate quorum of B independent branches over its full k-entry prefix, and the attacker must supply one one-use kernel to each branch for every entry certified. Prefix commitment serializes finality and each kernel is one-use, so splitting cannot help; 1,000 clones cost \\(5{,}005{,}000\\) kernel for \\(B=10\\). A quorum of colluding branches breaks it.",
