LSC 6.2.0 is the latest preprint-stage continuation of the public LSC 6.0 phenomenological framework. It introduces a detector-frame tensor anisotropy formulation that separates propagation-level true energy from detector-level reconstructed energy. The draft is prepared for arXiv submission and is currently awaiting category endorsement.The model is not presented as confirmed new physics. It is a testable phenomenological ansatz requiring independent review, numerical fitting, and constraints from BEST/GALLEX/SAGE gallium source data, KATRIN beta-spectrum measurements, IceCube anisotropy/systematic studies, and standard three-flavor oscillation data.This record is intended to preserve continuity of the LSC research line for grant review and independent verification. The recommended Zenodo strategy is to publish it as a new version of the existing LSC 6.0 conceptual record. The 6.2.2 correction is added here as a DOI-preserving extension note. Public note: the correction makes the isotropic trace explicit, keeps the directional term traceless, removes the mixed base 1 / E^2 usage, and anchors sidereal tests in a fixed celestial frame.
