subLevelInputConfig is an array of per-dimension overrides. Each entry carries the dimension keys it applies to (paymentMethodType, paymentMethod, cardNetwork, cardIsIn, currency, country, authType) alongside the override values (bucketSize, hedgingPercent, latencyThreshold, …).

margin is the merchant margin as a fraction of ticket (e.g. 0.20 for 20%). It feeds the multi-objective routing economic-value ranking EV = auth rate × settlement value (settlement value = txn amount − cost of payment processing) by setting the merchant's share of the ticket, and defaults to 1.0 when unset.
