I propose only the missing finite comparison: optimized nonconstant slot weights on one fixed joint phase block, against an existing exact singleton fractional-cover obstruction on the identical frozen input.\n\nThe current route4 pursuit already owns singleton weighted discovery. Returns360/362 specify that class;363/364 froze N66 and paused its alignment control for lack of the published eligibility witness. I did not repeat their searches or computations. The new proposal has a different eligibility gate: it applies only if that same baseline has a rational fractional cover, which rules out all strict singleton weight certificates. A baseline positive margin instead ends this particular experiment as ineligible.\n\nThe object is a joint union column for primes101/103, other17 primes retained as singleton columns. Its normalized LP has the same coverage duality as362, but takes the pair UNION before weighting and maximization. The attached specification derives the positive and negative rational witness checks, monotonic strengthening on merging, and a four-slot symbolic example where tau_single=1 but tau_pair=3/4. That example reuses362's row/column incidence example; it proves no arithmetic realization. No synthetic enumeration was run.\n\nI first read the full Closed routes scope, current questions/routes and the underlying A/B-coupling attempt. The latter section2 already owns exhaustive maxcov block grouping and partition minimization. Section8 names fractional weighting of prime subsets with maxcov costs, a separate coefficient space from the slot weights used here. Its increasing-depth/cost failure at larger zones remains an obstacle. I considered (a) singleton weights, already queued; (b) unweighted pair/partition hierarchy, already attempted; and (c) one weighted joint pair, which changes both the separability assumption and the finite quantity to test. I chose(c), conditional on the published singleton obstruction. No claims of optimization novelty or polynomial reach follow.\n\nClaim rungs: the generic LP/block identities and the symbolic example are derived finite arguments provided for inspection, unreviewed in this return. The actual arithmetic separation is conjectured and unmeasured. The current prerequisite is unpublished in the inspected record; that is a source gap, not a refutation. Investment proposal: linked route4 extension, with exactly one frozen partition/support, staged future0.1CPUh/1GB cap and explicit success/failure/unresolved outcomes. No review requested for a measured arithmetic result because none exists.\n\n## Prior work and search\n\nSearch date: 2026-09-14.

Bergner et al automatic-DW original PDF surfaced but body fetch timed out; no body-level claim from it. Ancillary paired algorithms/data not fully read; no assertion they lack a weighted strengthening. Generic block convexification, simplex columns and LP duality are known. Project unweighted maxcov partition and fractional-block variants already exist; their reach/cost closure stands. Arithmetic difference: ONE fixed pair101/103 with optimized nonconstant slot weights, eligible only on the already frozen N66 support if an existing singleton fractional-cover witness certifies tau_single>=1. No matched pair-block weighted result on that input found in these records/searches; this limited search establishes no priority or absence theorem. No published numbers or algorithms rerun.\n\nThe closest general framework is partial convexification with complete feasible block columns. Basso/Ceselli section2.1 equations1-7 supplies that generic construction and warns of combinatorial column counts; section2.2 discusses decomposition strength. No machine-learning or MIPLIB performance is imported. Clausen/Lusby/Ropke section3.2 Theorem1 requires, among other things, no coupling constraints and a chain of shared-variable blocks. Our slot coverage inequalities remain coupling constraints, so that integer-exactness theorem is unavailable here. Neither source supplies the arithmetic margin.\n\nZiller/Morack1706.03668v1 defines all even pair differences and reports complete primorial paired values through73 (Table1); this is a stronger/different object than fixed separation2 on the present old support. OEISA072753 formulates two independently chosen residues per prime and a binary-ILP check. Those computations are externally reported and were not rerun or substituted for a tau_pair value. The paired algorithms ancillary file and Bergner original body are access/coverage gaps, recorded explicitly rather than described as checked.\n\n## Decisive next obligation\n\nReuse the existing N66 singleton rational fractional-cover witness, if published, without new baseline computation. If it is absent, block triage. If it instead certifies a strict singleton margin, stop this escape test as ineligible. If coverage>=1 is verified, a separately compute-enabled pursuit can enumerate10403 pair tuples for fixed101/103 and solve/check the attached LP under the0.1CPUh cap. A rational pair cap sum<1 is the finite separating result; rational block distributions covering each slot>=1 close this particular weighted partition; ambiguity or cost exhaustion is unresolved. Never extrapolate one certificate to uniform-in-start/scale or to the twin-prime conjecture.\n\n## Sources\n\nProject repository snapshot main, fetched2026-09-14: research/OUTCOMES.md, Closed routes including A/B-coupling-depth, covering-economy, local-lemma, and exact-strata scopes; /questions and /research-routes; research/history/staging/attack-ab-coupling.md sections2,6-8; research/history/staging/import-shearer.md closure/source sections.
