Persistence or Turnover? A galaxy–galaxy lensing programme for the excess-acceleration fork in KiDS-1000. II. Certified spectroscopic isolation, a four-fold reproduced deep-tail slope, and a frozen decision protocol for DESI DR2

Summary and scope

A follow-up lensing analysis studies isolation selection and reports a deep-tail slope for its stated catalogue cuts. The registered primary precision threshold was missed: seven points qualified and the eighth had a 0.105-dex uncertainty against a 0.10-dex limit. Supplementary slope comparisons and full-profile fits favour different aspects of the tested models. They do not constitute a general exclusion of dark-matter or modified-gravity theories, and the framework’s original gravitational coupling remains unestablished. The data work and frozen decision protocol are historical results; no further campaign is commissioned here.
