A Seal is a wallet. You never buy the Seal — you buy a fork-share: royalty-bearing equity on its descendant tree. Every fork routes a discounted royalty back up its lineage, so a fork-share appreciates as the bloodline forks downstream — the exact opposite of a copy, which dilutes with every duplicate. The discount (0.618 per generation) makes deep descendants matter less and less, so an unbounded tree still prices to a finite, convergent number. The founder of a winning line is worth the most, because of its progeny. Value flows up.
node arena/lifecycle.mjsPrice = Σ over descendants ( share × 0.618^depth ) · a single lineage is bounded by 2.618 (the sum converges). Royalty on a descendant's settlement pays 0.618^depth up to each ancestor. This reads the same genealogy the Arena breeds and the Clinic matures — the fork-tree was always in the data; here it earns.
