Phase-Model Paper 03: A Phase-Reconnection Closure Model for Coronal Heating

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-reconnection closure model for the coronal-heating problem. The framework introduces a phase-driven heating term linked to magnetic complexity, formulates threshold metrics and falsifiable predictions, and provides explicit rejection criteria under cross-observational validation.
