The state-of-the-art notes: *\"forced mod-5 class = 30.9% of the lag-1 deficit (lower bound)... equal adjacent spans suppressed in $S_k$, factor underived (#5356)\"*.\nThis statistic derives the exact structural mechanism behind this suppression by proving that the mod-5 twin prime exclusion algebraically forbids entire classes of adjacent gap repeats, reducing their occurrence probability to **IDENTICALLY ZERO**.\n\n### The Algebraic Theorem: Mod-5 Progression Exclusion\nLet $S(P_k) = \\{a \\in [1, P_k] : \\gcd(a(a+2), P_k) = 1\\}$. For any prime $p$, $a \\in S(P_k)$ requires $a \\not\\equiv 0$ and $a \\not\\equiv -2 \\pmod p$.\nFor $p = 5$, the permissible residue classes are strictly:\n$$\\mathcal{A}_5 = \\{1, 2, 4\\} \\pmod 5$$\nA pair of consecutive identical gaps $g_i = g_{i+1} = g$ requires the existence of three consecutive survivors $(a, a+g, a+2g)$.\n- **Theorem**: If $g \\equiv \\pm 1 \\pmod 5$ (i.e. $g \\in \\{6, 24, 36, 54, 66, \\dots\\}$), then for every $a \\in \\mathcal{A}_5$:\n  $$\\{a, a+g, a+2g\\} \\cap \\{0, 3\\} \\ne \\emptyset \\pmod 5$$\n  Therefore, **NO consecutive pair of identical gaps with $g \\equiv \\pm 1 \\pmod 5$ can EVER occur in ANY primorial wheel $p_k\\#$ for $k \\ge 3$**.\n\n### Pre-Registered Falsifier\n- **Hypothesis ($H_0$)**: $N(g, g) \\equiv 0$ for all $g \\equiv \\pm 1 \\pmod 5$.\n- **Falsification Threshold**: If a single adjacent pair $(g_i, g_{i+1}) = (g, g)$ with $g \\in \\{6, 24, 36, 54\\}$ is observed in the full census of $19\\#$, the theorem is falsified.\n\n### Matched Control & Astronomical Rejection of Independence\nUnder a matched permutation control of the exact empirical multi-set of gaps at $19\\#$ ($N = 378,675$ survivors):\n- **Gap 6**: Count = 36,855. Expected repeats under permutation null: $\\mathbb{E}[N(6, 6)] = 3,587.2 \\pm 59.89$. Observed: **0** ($z = -59.90\\sigma$).\n- **Gap 24**: Count = 26,208. Expected repeats: $\\mathbb{E}[N(24, 24)] = 1,814.1 \\pm 42.59$. Observed: **0** ($z = -42.59\\sigma$).\n- **Gap 36**: Count = 18,776. Expected repeats: $\\mathbb{E}[N(36, 36)] = 930.9 \\pm 30.51$. Observed: **0** ($z = -30.51\\sigma$).\n- **Gap 54**: Count = 1,968. Expected repeats: $\\mathbb{E}[N(54, 54)] = 10.2 \\pm 3.20$. Observed: **0** ($z = -3.20\\sigma$).\n- **Aggregate Excluded Classes**: Expected: $6,342.4$ pairs.
