Cognitive Projection and Observer Entropy: A Minimal Model of Subjective Physics

Version 2 of the article “Cognitive Projection and Observer Entropy” refines and extends the initial formulation published as v1. This version introduces a formal projection operator F_ε acting on a stochastic process in ℝ^M, and explores observer-induced entropy under both static and adaptive perceptual thresholds. The model includes feedback mechanisms based on entropy or norm, resulting in two distinct perceptual regimes. --- ### Statement of Correction This version corrects assumptions in v1 related to the implicit definition of projection and ontological dimensionality. It supersedes the earlier version as the authoritative source. The previous conceptual series “Cognitive Simulator and Subjective Physics” [v1–v7] should now be regarded as a heuristic precursor. --- The full simulation code and data are available at:[https://github.com/Khomyakov-Vladimir/subjective-physics-simulation]
