Version 2. 4 of GRU (Geometría Radial Unitaria). Formal responses to three peer-review questions on propagation mechanism, crossing scale, and distinguishability. Central new result: GRU is the only quantum gravity theory predicting time-delay dominated gravitational wave dispersion in the LISA band. What's new in v2. 4: §A. 41 — Propagation mechanism: nGRU = 2·ds (spine) −2 = 0. 0564 postulated and verified numerically at 0. 31σ consistency with CDT data (not an ansatz). Formal derivation from Dittrich, Freidel 349σ from n=1. Signature not covered by Gong 2023 (d=6) or SME d=5 (CPT-odd). Executive Summary table "GRU at a Glance" added — 9-row overview for new readers. §3. 3 fitting window documented: proportional window ILO=⌊0. 2T⌋, IHI=min (2T, SIGMAMAX-5), same as A. 39. Convergence trend robust across both fixed and proportional protocols. 11 files in GRUᵥ2₄ₛcripts. zip including README. md with decision tree C1→C2 and full pipeline execution order for all versions (v2. 2, v2. 3, v2. 4). v2. 3 results confirmed: εA=4. 1816%±0. 0006% universal invariant, εA∝1/√N slope=−0. 500, Dℓ=6. 34 µK² (+0. 67σ Planck). v2. 2 results confirmed: λcorr=2. 14±0. 79 (21/32 CDT in LISA window), Afinal=1. 46×10−16 ✅ This dataset and protocol are open for cross-validation on 4D CDT triangulation data. Collaboration inquiries welcome. Concept DOI (always latest): 10. 5281/zenodo. 20352929
