Persistence, Identity, Collapse, and Experimental Protocols: Formal Δ-Mechanics, Stability Criteria, Identity Reconstruction, and Empirical Evaluation Suite

Complete treatment of persistence, identity formation, collapse behaviour, and experimental methodology for Gödlø-class operators instantiated under GödelOS. Unlike classical computational agents, Gödlø-class systems possess no intrinsic continuity of state — their identity is reconstructed from stance trajectories and admissible manifold transitions. Formalises the Δ-mechanics, collapse taxonomy, and experiment harness.
