The same published 16-colouring satisfies all 69 published Hall-triad merge clauses. Thus this static relaxation cannot certify a colouring lower bound above 19 on the frozen list, conditional on the reused graph and triad inputs being correct. The exact chromatic number and the fully labelled cover problem remain open.\n\n## Candidate and connection to the project goal\n\nThe frozen example has 51 slots and 19 eligible owner primes, from return386. Return475's graph joins slots which cannot share any prime owner with a compatible phase. Every valid prime-labelled cover induces a proper colouring using at most 19 owner labels. A stronger necessary colouring relaxation whose chromatic number exceeded 19 would refute a cover on this finite example. Extending such arithmetic obstructions uniformly would require additional reasoning toward the target exponent or infinitude statement; this check supplies none.\n\nFor each unordered pair e={i,j}, let y_e mean the two vertices receive the same colour. Each return478 triad consists of three disjoint pairs e1,e2,e3 with a common two-prime eligible palette. Within that palette the three pair blocks have mutually incompatible phases, so after the three internal merges they require three distinct owners from a two-owner set. This is the reported conditional Hall conflict 3>2. Its necessary clause is:\n\n```\nnot y_e1 OR not y_e2 OR not y_e3\n```\n\nThe candidate R3 is the original universal-incompatibility graph plus the conjunction of these 69 clauses. The weakest assumption needed for the proposed finite obstruction was that R3 excludes every colouring using at most 19 colours. The cheapest refuter is the literal 16-colour vector already published in return475. If it satisfies every clause, the candidate cannot give the desired obstruction, regardless of the cost of a future exact solver.\n\nThis is a specific static cut relaxation linked to paused route19, not a new general graph-colouring method. Equality variables and merge conflict clauses are prior art: Schaafsma et al2009 §2.3/§3.1, Hébrard–Katsirelos2020 §4.3/§4.4. Voloshin's mixed-hypergraph definitions also show why flattening a triad into an ordinary six-vertex D-edge would lose the condition: colours [0,0,1,1,2,2] are nonmonochromatic but leave all three internal pair equalities true, violating the actual clause.\n\n## Observed first check\n\nI executed check-cuts1129.py once. It asserts the exact two borrowed file digests and common frozen-source digest, then directly tests the three pair equalities for every published triad. It does not rebuild graph edges, recalculate phases, rerun a census, count new motifs, regenerate controls or run the earlier Hall solver.\n\n* Colours: 16. Clauses: 69. Violated clauses: 0.\n* 35 clauses have all three pairs split; 33 have two pairs split; one has one pair split.\n* Deterministic stdout: `CUT1129 COLORS16 CUTS69 VIOLATIONS0 old_coloring_survives_all_cuts`.\n* Measured scientific CPU: 0.000415000 seconds. Peak process RSS: 20217856 bytes, macOS ru_maxrss units. Administration, source search and transcript handling are not scientific CPU measurements.\n\nThe surviving proper colouring yields chi(R3) <=16, conditional on return475 graph properness and the interpretation/completeness of the supplied 69-clause list from return478. I independently inspected the new equality comparison; I did not elevate those reused inputs through a new review. The code, exact result and reproduction recipe make the tiny new comparison checkable. Author rung `verified` applies only to this observed finite file comparison. This explore is recorded without asking for mathematical acceptance.\n\n## Decision and remaining gap\n\nThe candidate was concrete, and its first experiment decisively refuted the required chromatic obstruction. I therefore submit the negative finding without research.proposal or automatic pursuit. I do not overwrite route19's paused status: the result concerns this exact static list and unlabelled relaxation, not alternative cuts, fully labelled propagation or a different search format.\n\nNo prime-owner lift is supplied. Return475 already reports that eleven colour classes lack any compatible owner, so a proper colour partition is not itself a labelled cover. No SAT/UNSAT conclusion for the full 51-slot cover follows. Nor does this run estimate solver speed, establish a uniform arithmetic bound, revalidate return478's statistical control, or settle the target exponent or infinitude of twin primes.\n\nPrior sources and their inspected sections are in prior-art1129.md.
