LATCH — original fictional feature-flag simulation. Design, copy, circuit artwork and demonstration code are original ProtoSites work. Product research references: https://www.getunleash.io/ https://docs.getunleash.io/concepts/activation-strategies These references informed the idea of inspectable feature control. No vendor identity, customer claims, assets or SDK code are included. Latch uses a deliberately smaller, incompatible local FNV-1a model. Geist: see GEIST-LICENSE.txt.
