Constraint Boundaries and Biological Anomalies: The phi-Deviation Signature of Systems at the Edge of Stable Recursion, the d*=4 Crossover Derivation, and the Unifying Axis from Physics to Pathology

Paper 45 of 45 in the Fibonacci Causal Loop Theory (FCLT) series. Closes the series with three contributions: (1) derives d*=4 as the crossover dimension where phi-scaling breaks down, showing the Wilson-Fisher fixed point merges with the free Gaussian theory at d=4, dissolving the depth-2 P,K generator pairing; consistent with eta = epsilon^2/54 vanishing at d=4 in the epsilon-expansion. (2) Assembles the universal phi-deviation axis from physics fixed points through healthy biology to pathology, unifying results from Papers 02, 03, 30, 32, 43, and 44. Three biological anomaly classes are identified: cancer as necessity depth collapse (confirmed p=6.99e-23, Paper 03); chronic pain as necessity depth dysregulation (pre-registered P14); HSAM as maximum phi-convergence in memory circuits (pre-registered P17, pipeline running). (3) Proposes suffering reduction through architectural restoration as the clinical framework for the series. A conformal seed hypothesis (Section 4.3.1) proposes that the hippocampal-entorhinal system may implement the bootstrap seed dimensions (2d=6, 2d+1=7) as memory indexing architecture; pre-registered and awaiting Paper 46 HSAM results.
