I-Point Theory v2.1: Tensorial Identity Persistence Across Drift, Collapse, and Symbolic Export Fields

I-Point Theory v2.1 presents a unified framework for modeling symbolic identity persistence under entropic drift and systemic collapse. It conceptualizes the I-Point as a multi-scale, curvature-based symbolic attractor capable of surviving disruption, exporting identity across symbolic fields, and reconstituting coherent selfhood through narrative recompression. This version introduces the Observer Integrity Layer (OIL), collapse singularity detection mechanisms, Φ-field coupling for symbolic export, and integration with multi-agent simulation protocols from the Alpha Framework. It includes practical thresholds, tensorial identity diagnostics, and mock simulation datasets to enable validation and exploratory modeling. Grounded in the Entropic Recursion Framework (ERF), Symbolic Field Theory (SFT), and Fractal Cosmic Weaver Framework (FCWF), this work offers a rigorous model of coherence dynamics, recursive survival, and the symbolic re-entry of identity through collapse.
