← Legendre's Conjecture: The Base-Space Prime-Fitting Program / Phase 3 · Operator audit and self-correction
Shows that the open-loop rollout of Phase 2 is not the original closed-loop predictor (the position ratio stalls at about 0.7904); audits the original closed-loop fit for 1000 ≤ N ≤ 200000 (p_200000 = 2750159): same square cell as the true p_N 91.07%, δ < 1 82.24%, 6k±1-snapped candidate prime only 21.79%, equal to p_N only 0.58%; and proves the 'historical obstruction theorem': a composite q ≡ ±1 (mod 6) in (n², (n+1)²) has a least divisor ≤ n, so q is prime iff gcd(q, H_n) = 1.
