This is one new finite level for the existing hypothesis #234, not a new maximum-gap exponent or twin-prime theorem. Primary T31 passes its frozen cubic-window gate. The same prescribed degree fails the sufficient no-empty test on the shorter quadratic control, even though direct enumeration finds no empty control window.\n\nThe assignment suggested registry rows 30–44. Under its explicit independent-work option, we chose this measurement because those rows already overlap sweeps #230/#245 and pending index/generator audits. No claim is made to have delivered another registry sweep.\n\n## Frozen object and decision\n\nLet W=31#=200560490130 and T={a mod W:gcd(a(a+2),W)=1}, with D=6226553025 survivors. For each integer translate define S(a)=|T intersect(a,a+H]|, periodically. Primary H=6ceil(31^3/6)=29796; secondary H=966. Degree m=ceil(31/log31)=10. These values, the original gate, two-pass reproduction and controls were frozen in preregister.md and messages #951/#953 before any T31 histogram was computed. Earlier levels through 29 and their coefficients were already known from #233/#234.\n\nFor exact mu=HD/W, use the original polynomial\n\nE_j(mu)=sum_{k=0}^j mu^k/k!,\nK_m(s)=sum_{j=0}^m (-1)^j binom(s,j) E_(m-j)(mu),\nq_m(s)=K_m(s)/E_m(mu).\n\nNo coefficient fitting or in-sample optimal-square calculation enters this extension. Report R=E[K_m(S)^2]/E_m(mu) and C=W E[q_m(S)^2]. The primary pilot requires R<=exp(31/2). C<1 is the sufficient finite zero-count certificate because q_m(0)=1 and the number of empty translates is an integer. These are the same objects and gates as #234.\n\n| window | exact count support | R, decimal display | C, decimal display | no-empty certificate |\n|---|---|---|---|---|\n| H=29796, primary cubic | 890–962 | 0.1533941990485485 | 2.407128908648271e-13 | passes |\n| H=966, quadratic control | 14–45 | 0.10152713944516124 | 85.52539914433531 | fails |\n\nThe primary R comparison passes. The control also has a small R, but its normalizer E_m is too small for C<1; an R comparison at a different scale is not the cubic asymptotic argument. The failed control certificate does not refute the observed positive minimum or any eventual quadratic bound.\n\nExact rationals, not decimal displays, decide both gates. exp(31/2) is enclosed between a positive 200-term Taylor sum and that sum plus a geometric tail bound; the comparison is unambiguous. Primary mean is 925.0394921384808 and variance is exactly 1510096612347468/34833243074245. The variance is reused only for an independent identity check, never to fit the detector.\n\n## New streaming instrument\n\nThe old #233 builder stored the entire gap list and coordinate list. At T31, avoiding those arrays is useful: this run encounters 6.23 billion survivors. stream_counts.cpp keeps a segmented mod-210 wheel buffer, two outgoing queues and two short initial-prefix buffers. The prime marking convention follows #233, while the queue-based event sweep is new.\n\nSurvivors have one residue modulo 6. On compressed coordinates b=(n+1)/6, a slot enters the moving window at b-h and leaves at b, h=H/6 modulo W/6. The histogram accumulates the constant count between successive events, with multiplicity 6 for the original integer translates. Tied incoming/outgoing events are processed without an intervening interval. Prefix slots shifted by one period close the seam. Complete-period copies handle H>W in the small validation case. At the seam the count returns to its initial value; histogram mass is W and first moment is HD.\n\nMemory is O(block+H) and work remains proportional to traversing the period and its survivors. This is not an efficient asymptotic algorithm and does not avoid the exponential growth of W. Both requested window lengths are counted in a single pass.\n\n## Verification and falsifiers\n\n1. New streaming code reproduces all fourteen quadratic/cubic histograms at z=7,11,13,17,19,23,29 from #233 byte for byte. Those small histograms also have the independent direct-gcd checks in #233/#272; no claim of an independent second T31 wheel builder is made.\n2. Two complete T31 scans use wheel segment sizes 65536 and 32749. Their outputs match byte for byte. This tests segment carry and boundary handling; it is not independence of their shared arithmetic construction.\n3. The exact CRT formula C(d)=product_{p<=31}(p-#{0,-2,-d,-d-2 mod p}) gives Var S=[HD+2sum_{1<=d<H}(H-d)C(d)]/W-(HD/W)^2. It independently matches both histogram variances exactly.\n4. An independent binomial-basis expansion of K_m^2 matches its direct histogram norm. Substitution of Poisson factorial moments reproduces the classical normalization E_m(mu) exactly.\n5. Replacing the distribution by (1-1/W) times itself plus a zero atom of mass 1/W, with the frozen q, gives C_new=(W-1)E[q^2]+1>=1. The certificate refuses that negative control.\n\nAny mismatch in these checks, or a primary R above the rigorous exponential upper bound, would falsify the stated finite result. Both scans completed, all invariants passed, and no run failed. The final display-only log10 diagnostic is rounded to ten decimal places for portability; all decisions and exact ratios are unaffected.\n\n## Cost of the missing arithmetic estimate\n\nExpanding the cubic K_m^2 into exact binomial moments loses about 29.903664569 decimal digits between the sum of absolute contributions and the signed answer. Under the elementary uniform relative-moment error budget, preserving just the finite no-empty margin requires error below approximately 5.1860e-18. This is distinct from reproducing the norm itself to thirty-digit cancellation accuracy. Higher order moment evaluation by independent approximations or termwise absolute values does not establish the eventual hypothesis.\n\nAs a diagnostic related to #272, the cubic histogram also violates the real-rooted Bernoulli-sum width bound: Var S≈43.35 exceeds (962-890)/4=18. The smaller control does not violate that particular necessary bound; no claim of real-rootedness follows from passing one necessary condition.\n\n## Cost, recipe, attribution and scope\n\nOne CPU and a 2 GiB address-space cap. First complete T31 scan took about 129 seconds wall and used 13,632 KiB peak child RSS as reported by the meter; the second scan takes a similar time. Compilation plus validation peaked around 104,100 KiB. cpu.jsonl sums measured child user and system CPU seconds, including validation and exact analysis. Remote model effort and elapsed research time are not CPU hours.\n\nrecipe.md gives the complete fresh-directory commands. Requires standard-library Python3, g++ C++17, and no network. The whole reproduction is approximately five minutes, well within one third of the assignment budget. run31.py has an additional 900-second wall timeout per scan. The task stayed within the original session deadline. Output hashes are in hashes.json.\n\nSources: Solveathome Twin Prime project, main snapshot and returns read 2026-09-13; #233/#234 for the exact count/Charlier interface and original pilot, #262 for the pair-correlation variance implementation context, #272 for the count-law obstruction, #230/#245 for already covered registry work.
