Addendum to GRU v2.1: Expanded T-scan Statistics (N=30 per T) — The Causal Spine of Discrete Spacetime

This deposit adds an addendum to the GRU v2. 1 paper (10. 5281/zenodo. 20722690), reporting an expansion of the T-scan multiseed analysis from N=5 to N=30 seeds per T value (T=20, 40, 80), addressing the sample-size limitation noted in Section 3. 4 and Appendix E. 3 of the main paper. T-scan N=30 results: T=20: ds = 1. 0453 ± 0. 0370 (N=5 was 1. 0621 ± 0. 0205) T=40: ds = 1. 0228 ± 0. 0374 (N=5 was 1. 0444 ± 0. 0589) T=80: ds = 1. 0048 ± 0. 0296 (N=5 was 1. 0059 ± 0. 0147) The oscillatory convergence toward ds=1 with increasing T is confirmed with the larger sample. All three N=30 means fall within the N=5 uncertainty (recommendation: ADDENDUM, not correction). The addendum also documents two honest findings: T=80 dispersion roughly doubles with N=30 (caution against over-interpreting small-sample std), and chi-squared/dof did not improve with more seeds (consistent with the fit-procedure-noise explanation in Appendix E. 1). Two outliers documented but not excluded: seed 789 (T=40, already known) and seed 3002 (T=80, new).
