Abstract NTF-0 defines the thermodynamic substrate of navigation in Ambient OS. It establishes navigation as a reversible, field-based process governed by ΔR, permissibility, and embodied continuity rather than by goals, planning, or optimization. NTF-0 introduces core constraints for safe, endpoint-free navigation and forms the foundational layer for ITL-1 (definition), RR-1 (directional persistence), and AP₁-Y (soft vector motion). This document anchors Navigational Thermodynamics as a scientific framework for human-scale computing, embodied motion systems, and AI field interfaces.
