Calculation logic & audit view

The prototype calculates an additional sequestration scenario relative to a conventional-practice baseline. Management effects are modified by soil and weather conditions, then reduced by a conservative uncertainty buffer.

Credit = Area × AdditionalIntensity × (1 − Buffer)

AdditionalIntensity = Σ(management contributions) × soil_modifier × texture_modifier × weather_modifier

Data lineage: parcel → management inputs → soil baseline → weather / remote-sensing proxies → scenario estimate → conservative creditable amount.
