SUMMARYTech through the Ayiti lens: the summary (Nov 6, 2026). Lens: the land's people carried engineering long before the official "invented" dates: Tikal's water filters, Nazca puquios, Teotihuacan's mercury, Cahokia's solar posts, waru waru fields (P752, P755). Record: Ayiti built the Citadelle Laferrière (1805–20) on its own, the largest fortress in the Americas, with a large cannon battery, after defeating the French army (needs exact count). Record: the law made held people's inventions unpatentable (1858) and handed them to claimants (Confederacy, 1861); Garrett Morgan had to disguise himself as an "Indian helper" to sell his own gas mask (P759). Record: the reset of credit, Ford not first even by the official record. Record: the radium craze, poison sold as medicine to the people (P757)
