The 2025 on-ramp is a different spine from the 2026 Great Grok Challenge. This page holds the January–February validation week so those posts are not only a footnote on Origin Law. Numbers as posted. Kits not pasted. Challenge 15 (2026) is a later frozen-scaffold Bullet test, not this week.
29–30 Jan — first validation
29 Jan 2025 opened an astrophysical validation thread: weak-lensing κ and velocity-dispersion mass estimates without dataset-specific tuning. Same thread: a DES/HSC/CFHTLenS/KiDS/RCSLenS + SDSS DR17 + Chandra/XMM mass-scaling chart. The chart used an unfilled Python placeholder for fit coefficients; this atlas does not invent them. 30 Jan posted the ICL-growth equation.
Not claimed
The 30 Jan 2025 ICL-growth equation and the 29 Jan mass-scaling chart are archived so the first-validation week is readable. They are not 2026 supported cluster-mass or ICL results.
10–13 Feb — Bullet and ξ(r)
10 Feb 2025 posted a no-dark-matter Bullet Cluster closeout at 201.55 kpc (χ² 3.15 vs ΛCDM 4.22) and a four-cluster offset table. 13 Feb quoted ξ(r) vs KiDS/DES at χ² 7.42 vs ΛCDM 11.85. 2025 Grok-loop / kit-era numbers.
| Cluster | Observed (kpc) | Posted prediction | Deviation |
|---|---|---|---|
| Bullet Cluster | 201.55 | 201.55 | 0.00% |
| MACS J0025 | 177.00 | 176.80 | −0.11% |
| Abell 520 | 152.30 | 152.06 | −0.16% |
| El Gordo | 211.50 | 212.03 | +0.25% |
Posted 10 Feb 2025 as a universal weak-lensing-offset table. Not claimed. Challenge 15 is a different 2026 Bullet test.
Not claimed
The 10 Feb 2025 Bullet Cluster 201.55 kpc closeout and the 13 Feb ξ(r) χ² 7.42 vs ΛCDM 11.85 are not 2026 supported cluster or clustering results.
