Changes in v4 (May 2026) Partition function weights corrected: Per-mode weights updated from the superseded phenomenological form wₙ = φ^−λn/𝒩 to the modular-covariant Gaussian wₙ = C·exp (−πn²/9), C ≈ 0. 500, consistent with the unified parameter set in Paper 3 (doi: 10. 5281/zenodo. 20248650). The golden-ratio simplicial weight φ^−N (𝒯) in the CDT path integral is unaffected — it is a distinct quantity. Figure 1B caption corrected: Δλ = 1. 729 → 1. 7287 (exact value 2π/ (9κCE) ) Figure 3B caption updated: Tower heights now stated in terms of Gaussian weights (w₀ ≈ 0. 500, w₃ ≈ 0. 022, w₆ ≈ 10⁻⁹) ; panel schematic was produced under the superseded weight and will be updated in a future revision §5. 2 enhancement factor corrected: ηdiff·φ^−3 formula replaced by correct Gaussian ratio w₃/w₀ = e^−π ≈ 0. 043 Piano mathematics section updated: 3-6-9 node hierarchy restated using Gaussian weight values; residual ~15% amplitude claim removed Modular covariance paragraph updated: Orphaned reference to old phenomenological weight removed; Gaussian weight covariance stated with S-invariance breaking quantified (|w₀ − 1/9| ≈ 0. 39) CDT and BMS defined on first body use Strominger (2014) cited at first IR-triangle invocation M-Theory companion citation updated to v9e with full subtitle Paper 3 companion link updated to v3 DOI (10. 5281/zenodo. 20248650) Paper 1 cross-citation added: Einstein Equations from Prismatic Curvature (doi: 10. 5281/zenodo. 20146627) Typography: microtype expansion=false; emergencystretch=2em
