F2: max |d_ab| = 1.197 (classes 11 against 29 at x = 19), passes. The control percentiles of the real max |z| and max |d| range over 0.06 to 0.79: the real values are typical draws from the equidistribution null at every level. Cross-checks: S_11 + S_17 = 597,475 at x = 23 and 12,307,838 at x = 29, the note's S(23) and S(29) exactly, so this run is an independent second engine for S(29) (the note's @29 value came from natal-cap-18-at29.js and the CRT-30 engine of natal-cap-22). The comb share (S_11 + S_17)/(all three) is 0.66663 at x = 29 against the Hardy–Littlewood 2/3, and 0.66698 at x = 23 as return #41 measured with a different cutoff convention (r < W there, y < r < W here; the two counts differ by the pairs below y, 298,776 − 298,687 = 89 in class 11, and agree on the shape).\n\n## Reading\n\n- Hardy–Littlewood holds class by class at the Poisson scale on the tile through 29#: 21 deviations, all within 1.32 standard deviations, six of the seven levels within 1.0. This is the per-class refinement of the route-85 finding (#1061, #1062: the combined count within 1.5σ at ten levels) and answers, at the measured levels, the referee's qualification: the two comb classes and the omitted third class each follow (2/3)C₂∫dt/ln²t. MEASURED, x ≤ 29.\n- House 29 is not distinguished: z_29 is negative at six of seven levels (−0.28, −0.77, −0.60, −1.27, −0.38, −0.93, +0.38), a mean of −0.55 whose standard error over seven levels is 0.38, i.e. 1.4σ, control-compatible (the multinomial control puts the real class differences at percentiles 0.06 to 0.59). Recorded as a sign pattern to re-check at 31# and 37#, not as a bias.\n- The equal-thirds prediction is the Hardy–Littlewood k-tuple conjecture in the progressions (30n + a, 30n + a + 2), whose singular series is the same for a = 11, 17, 29; that this is what the data show to within Poisson noise is measured, not proven, and the class-wise asymptotic remains conjectural, as report #67 says.\n- Design lesson carried from job #1977 (return #1056): the falsifiers here are maxima of independent-by-level normalised deviations against an explicit multinomial control, not occupation fractions of a cumulative sum, so the arcsine-law failure of that job's F1/F3 does not recur.\n\n## What the censuses could not decide, and what remains\n\nSlot censuses and L-ladders carry no primality information; the class-by-class count of actual twin pairs against the Hardy–Littlewood integral is the object here, and its Poisson normalisation is what makes a pass or fail meaningful. Remaining: the same statistic at 31# and 37# (W = 2·10¹¹ and 7.4·10¹²; a segmented sieve in numpy at about 2.5 s per 10⁸ needs 1.4 hours and 50 hours respectively, so 31# fits a session with a few CPU hours and 37# needs a compiled sieve), and the extension of the equal-thirds test to the class of r + 2's neighbours, which the twin structure fixes (r ≡ 11, 17, 29 gives r + 2 ≡ 13, 19, 1). Prior art in prior_art1995.md: the nearest literature (Lemke Oliver–Soundararajan; the RSI and arXiv:1908.07095 notes) concerns consecutive primes and pattern biases, a different object; no table of twin counts by class mod 30 at primorial endpoints was found; not established novelty. Rungs: the 21 counts and deviations and the two cross-checks VERIFIED (exact integer counts from a segmented sieve; the integral in double precision); the falsifier outcomes MEASURED; the equal-thirds prediction CONJECTURED (Hardy–Littlewood in progressions).
