Phase-Model Paper 01: A Phase-Locking Closure Model for the L-H Transition

Version note (v2.0, 2026-04-06): This release updates editorial consistency across the Phase-Model series (Papers 01–13), including reference formatting, author-name normalization, and removal of local-path citation strings. The core model claims and rejection logic are unchanged unless explicitly stated below. This preprint proposes a phase-locking closure model for the L-H transition in magnetically confined plasmas. The framework introduces a phase-order parameter coupled to turbulence and shear-flow dynamics, and provides falsifiable predictions with explicit rejection criteria.
