Two Eyes — Your phone sees the muddy river. The satellite sees the scar upstream. Film a muddy river from a public spot: a bridge, a riverbank, a ferry landing. Two Eyes traces the river upstream, looks for new forest clearings in Sentinel-2 imagery (often galamsey, illegal gold mining, in Ghana), cross-checks them against independent datasets (HydroRIVERS/HydroBASINS drainage, RADD radar alerts, Hansen GFC, WRI drivers, WDPA), and returns a dated, anonymous evidence card you can share on WhatsApp. The card shows badges, never a probability, and its wording only goes as far as the agreeing checks allow ("Likely source of this mud, not proven"). Validation (frozen-cutoff test, 27 Oct 2026): a CERSGIS-measured 5.49 ha Atewa clearing was detected at 4.34 ha; intact-forest and cocoa-farm controls read 0.00 ha.
