What this record does not yet support — disclosed, not estimated

Risk-adjusted discount rate — deliberately not published. A province-level base is mechanically computable from the published formula (r = 8.0% + (10 − IC) × 0.8%), but Afrimintel does not publish an asset rate without asset-level tenure, settlement, and structure screening (the §10 worked-dossier process). Publishing the base alone would misstate asset risk. Each worked decomposition converts this Absent to a Derived range.
