SHIPPED_FEE_POLICY top-level property

FeePolicy SHIPPED_FEE_POLICY
final

The shipped template (config_constants defaults): 10% Bernoulli fee, a 2.2% per-leg floor, a one-day ramp window that is inert at a 1.0 multiplier, a 1%–99% entry band, and inventory impact disabled. A market created under these values charges exactly this; one created after an admin change does not, which is why the per-market snapshot is the real answer. Verify against the deployment's MarketCreated before pricing money on it.
