"answer": "harbor mints one lease each epoch and binds key, endpoint and parent, so a sparrow, one clone, collides there instead of multiplying. Every lease decays to zero at epoch end and must be re-bought singly; after each sale the next lease costs one more river, so keeping n sparrow alive for an epoch burns 1+2+...+n river into their harbor records, serial and nontransferable. It breaks if harbor dedups weakly, leases or river move, the auction shards, or decay is paused.",
