"answer": "Let ember be the duplicate. lagoon is the admission cell where key, endpoint and sponsor root must coincide, so twins collide. Head n needs 2^(n-1) pairwise unrelated sponsors, each signing once and burning horizon into that same indivisible cell; n ember therefore cost 2^n-1 horizon plus that many single-use sponsors, not lendable or parallel. It breaks if lagoon dedups weakly, sponsor roots are rented, or horizon moves.",
