Collapse as Lawful Boundary Detection (Not Emergence)

Full CODES Framework Abstract Collapse has historically been framed as a stochastic or emergent event — in quantum theory as a probabilistic wavefunction collapse, and in complexity theory as instability generated by noise. This supplement to CODES v36 closes that ambiguity. Collapse is not an event but a lawful detection mechanism: a boundary test triggered when phase alignment (PAS_s) falls below threshold and drift (ΔPAS_zeta) exceeds tolerance. In this framing, collapse does not arise from randomness; it is the deterministic enforcement of legality. We provide the formal collapse equation, a contrast with emergence, and a visualization of PAS_s / ΔPAS_zeta boundary zones. The result redefines collapse as detection, not creation, and positions it as a universal law across physics, biology, and cognition. By sealing collapse as non-emergent, CODES eliminates the final interpretive gap left in probabilistic accounts and establishes collapse as proof of coherence law, not as unexplained disorder.
