Boundary, Observer Attention, and Time Axis: Unified Framework of Generalized Entropy Geodesics and Section Universe

Construct unified framework of time and observer with boundary as fundamental stage. Assume in gauge field state without observer readings, boundary data of spacetime and fields are determined, but no preferred time parameter exists; time only appears as ``geodesic parameter'' when observer performs readings and their attention selects boundary section family. First, on scattering theory end, based on scale identity define observable time scale as unified reading of boundary scattering phase, re
