AP₁-Y — Yellow Navigation Engine

Abstract AP₁-Y defines Yellow as the exclusive field of voluntary navigation within Ambient OS. It specifies directional vectors, bleed mechanics, navigational attractors, entry/exit laws, and strict prohibitions against autonomous or AI-initiated motion. In the canonical grammar, intent never originates in Yellow. Navigation becomes possible only after pre-navigational definition in Purple (ITL-1), which provides a non-linguistic anchor for direction without imposing goals. Yellow therefore expresses will-made-motion, not destination selection.It preserves full reversibility, ΔR stability, and non-agentic behavior by ensuring that movement never self-defines its purpose. Direction is anchored externally; motion remains purely human-driven.
