Delvehold has no existing economy surface to cut against: its world host
names a commons market id and nothing else. The shape is therefore
constrained only by the invariants above and by the verification fixtures
below, which is why those fixtures are written before the engine is.
Still the operator's:
1. The market maker: logarithmic scoring rule versus constant-function curve.
Recommend the scoring rule for its bounded loss and single liquidity
