The uniform statement\n`Ghat(2s) <= 8 Ghat(s)` remains OPEN, as does the sufficient maxsum condition\n`maxsum_{K*(s)+1}(T_s) <= 8 Ghat(s)`. No period walk, covering search, hierarchy\ncalculation, contributor-code execution or new numerical experiment was performed.\nNo novelty or new asymptotic result is claimed.\n\nThe bounded test selected here was whether the nearest published paired-Jacobsthal\nupper envelope supplies that missing bridge. It does not: its finite values are\nfor a larger object, and its proposed uniform upper bound is conjectural. This\nnarrows an import, not the original mathematical question.\n\n## Existing evidence, with its grades preserved\n- The bridge note section 3 step 3 already proves the per-step maxsum certificate.\n  Its K*-product replacement and the per-fold product composition are closed by\n  OUTCOMES for the stated methods, not as refutations of D8 or M8. Those arguments\n  were not rerun or reopened.\n- Accepted #6783, final rung measured, with trusted review #2420: the sixteenth\n  distinct finite step 19#->41# has reported K*=16 and M8 ratio 648/150=4.32.\n  The review independently checked the tail, wrap, argmax and endpoint gap, not\n  the entire initial period. This is cited measured evidence, not an independently\n  reproduced full-period exclusion here. Its sixteen-step list is not an exhaustive\n  list of later project computations.\n- Accepted #5550, final rung measured, with review #1940 on the served record:\n  M8 holds at s=28,29, and, with its cited earlier rows and identical-object\n  intervals, through s=29. Its author's stronger headline is not promoted over\n  the server's measured rung.\n- Accepted #966/review #197, verified: K*(32)=25, including the corrected wrapping\n  predicate A on one block and A-P on the next. Accepted #969/review #198, verified:\n  maxsum_1(T_31)=348, maxsum_26=1380, maxsum_27=1428. Together with the existing\n  per-step theorem these give the known s=32 certificate 1380/348=115/29<4.\n  Route23 is already known, revision22. None of these finite statements settles\n  all s, all chain rungs, or an eventual statement.\n\n## Closest external sources and the transfer test\nExternally reported, not reproduced: Ziller and Morack, arXiv:1706.03668,\nDefinitions 2-4 and Table1, compute h2(n)=j2(p_n#) through n=21, p_n=73.\nThe quantifier is every even pair difference, whereas G2 here fixes difference2.\nThus G2(p_n#) <= h2(n); there is no equality assertion. The table gives h2(11)=570\nat p_11=31. The project bridge note gives Ghat(16)=G2(13#)=66 and Ghat(32)=348.\nConsequently the direct sufficient substitution\n\n    Ghat(32) <= h2(11) <= 8 Ghat(16)\n\nfails at its second inequality: 570 > 528 = 8*66. Equivalently the envelope ratio\nis 95/11 > 8, although the fixed-difference truth ratio is 58/11 < 8.\n[Elementary arithmetic on cited values; no new measurement.] This refutes only\nusing that exact all-even-differences envelope as an all-s C=8 certificate.\nIt does NOT refute D8, M8, a sharper fixed-difference theorem, a different larger\nconstant, or an eventual version excluding s=16. The previously known distinction\nh2 >= G2 is already in recon-0828-covering section3 A4; this is a scoped calibration\nof that distinction, not a claim to have discovered it.\n\nZiller and Morack, arXiv:1706.00317, Definition2.2, Conjecture6 and Theorem4.1:\nh2(n)<p_n^2-p_n for all n>=3 is a CONJECTURE; the proved implication from that\nconjecture to Goldbach and prime pairs is not a proof of its premise. Neither\npaper supplies the required uniform upper bound for a covering run on the\nnonuniform old-slot sequence. Even an absolute ceiling on the larger h2 alone\nwould still need comparison to the old fixed-difference record to certify D8.\n\n## The gap that remains and a decisive check\nDefinitions: T_s is the periodic ordered set of r with gcd(r(r+2),P(s)#)=1;\ngbar(s)=P(s)#/|T_s|; K*(s) is the largest run of consecutive T_s slots killed by\nentering primes (s,2s]; rho(s,m)=maxsum_m(T_s)/(m*gbar(s)). The existing sufficient\ncondition is exactly\n\n    (K*(s)+1) rho(s,K*(s)+1) <= 8 Ghat(s)/gbar(s), for every required s.\n\nThis is the already located unresolved obligation, not a new theorem. The CRT\nfloor K*>=pi(2s)-pi(s) is in the wrong direction. Replacing the left side by a\nper-prime product revisits a closed method. Adding another finite checked rung\ncannot establish the quantifier. A useful changed premise must instead give a\nuniform covering/weighted-span upper bound, with hypotheses checked for these\nold slots and with constants compatible with their records.\n\nCheapest decisive check of this particular import: read h2(11)=570 in Table1,\nGhat(16)=66 in the project source, and compare 570 with 528. A wrong table/index\nor convention would overturn this scoped transfer failure; a newly proved\nfixed-difference uniform inequality would change the wider assessment. For the\nuniform M8 conjecture a falsifier is any exact same-domain rung with\nmaxsum_{K*+1}>8 Ghat(s); that would refute this sufficient method, not necessarily\nD8. A proof needs all required s, not absence of finite counterexamples.\nNo new route is proposed because no distinct working mechanism was obtained.\n\n## Search, coordination, and limitations\n2026-11-02: Firecrawl Research semantic search for generalized Jacobsthal / paired\nresidue classes / primorial doubling returned the paired computation paper and\none-class neighbors. A second named-author search located the theory paper.\nTargeted in-body reads inspected the paired definition, finite table and\nconjecture/implication. The search is bounded, not a literature-absence proof;\none-class papers were identified, not read as if they supplied two-class results.\nAn additional general-web search timed out before saving output; it supplies no\nnegative evidence. The successful research reads were preserved and not rerun.\nNo MathSciNet/zbMATH search or full ancillary computation-code audit here.\n\nRead research/README.md, the assigned QUESTIONS row and relevant OUTCOMES rows,\nbridge note, covering recon sections2-3, route23, lane chat/work-state and the\nabove accepted returns with their supplied reviewer notes. Claim message10322\nstates the source-only experiment; reply check returned no messages. The broader\nlane's work-state snapshot has no decisions; that is not a global novelty check.\nThe registry's PARTIAL classification remains correct. Existing finite-count\nupkeep/advisory corrections are not duplicated as a fresh audit or described as\nintegrated.
