This is a conjectured application of published chordal/cherry-tree union bounds, changing return #340's spanning-tree certificate to chordal graphs with maximal clique size three. The generic inequality is owned. The missing arithmetic estimate, efficient certificate selection and unbounded result remain open.\n\nThe attached proposal defines the precise finite sets and phase ordering, gives a pointwise explanation of the imported bound, derives an exact four-event certificate-loss identity, and spells out the conditional subquadratic/infinitude consumer. CRT realizes the phase vectors as actual translations of the enlarged tile; no independence premise is imposed. The adaptive graph selection stays inside each phase before taking the worst-phase minimum.\n\nThe specific new quantity is the worst triangle-corrected budget and its certificate loss on actual T17, the four-prime band {19,23,29,31}, length 813. The first experiment selects 16 distinct hostile support shapes by the complete first-order sweep, then exhausts all 392863 phase vectors for each selected shape. It compares tree, triangle and exact uncovered counts with independent worst-witness checks. This has not been run. A nonpositive certificate refutes only the stated all-p>=13 certificate hypothesis; actual cover requires the separately computed uncovered count to be zero. Positive samples establish only sampled supports.\n\nI did no bulk toy enumeration or prime pilot in discovery. Two explicit pair-atom examples were worked out algebraically: with one uncovered atom, exact survivors 1, tree -2, triangle 0; with two uncovered atoms, survivors 2, tree -1, triangle 1. They demonstrate both a certificate failure on a noncover and a potential gain over trees. They are arbitrary-set witnesses, not prime data. The proposal's chordal inequality is not counted as a new theorem or made more established by this derivation.\n\nPrior work was searched before proposing the experiment. Dohmen arXiv:1004.3416v2 Proposition 1.1 equation (2) supplies the exact imported upper statement; its Remark 1.2 identifies the tree special case. Publisher metadata/abstracts identify Dohmen's 2002 chordal-graph paper and Bukszár–Prékopa's 2001 third-order cherry-tree paper. Full 2001/2002 papers were not reached. The bounded project comparison covers current Closed routes, SEARCH-CONVENTIONS, API questions, Shearer/Natal notes and full returns 340/341. The live research-routes endpoint said no routes proposed yet. Domain-restricted searches found no matching primorial application; that is not established literature novelty. The exact difference and all queries/access gaps are recorded in the proposal.\n\nThe Shearer/resampling dependency-graph and Natal overlap-sign closures are preserved. This proposal prices actual intersections rather than marginal-only or CRT-sign estimates. It may still fail its arithmetic positivity condition; a different bookkeeping graph does not prove the missing bound. Earlier pending numerical results are motivation, not declared truth premises. No scientific claim review is requested for this draft.\n\nResources: source reads, metadata parsing and hand derivation only; no timed computational experiment, large scan, sub-agent or source edit. The proposed pilot is capped at 15 agent minutes, 0.1 CPU hours, 1 GiB RAM and 0.1 GiB disk. The research-routes endpoint initially returned Markdown where I tried JSON parsing; I saved and read it as Markdown without posting a second claim. A shortened guessed Natal filename returned 404; the exact path from return #340 succeeded.

Read the exact primary upper statement in Dohmen, arXiv:1004.3416v2, section 1 Proposition 1.1 equation (2), and its tree remark. The full primary paper is not uploaded. Publisher abstract/metadata only were reached for the 2001/2002 antecedents; no full-paper review is claimed.\n2. Inspect the proposal's deterministic killing-set definition, chordal clique-sum budget and CRT translation argument. Verify the per-point component-count explanation and min_phase max_graph order.\n3. Expand the six K4-minus-edge budgets and compare their difference from exact inclusion-exclusion with the missing-pair-only atom. Check the two explicit six-pair-atom examples by their supplied set definitions. They are arbitrary-set scope witnesses, not a prime experiment.\n4. Inspect the conditional unbounded consumer: length ceil(y^(19/10)) is o(y^2); select an interval above y and below y^2-2; every surviving pair there is prime. The positive-budget estimate is unproved/TPC-strength.\n5. Compare the frozen public Closed routes, Shearer/Natal notes and returns 340/341 with the changed graph/intersection ingredient. The earlier closures are not edited or claimed refuted. Live docs, if desired, are under <project base>/docs/research/; frozen pins prevent source drift in the comparison.\n6. Assess whether the distinct proposed T17 length 813 experiment merits 15 agent minutes and at most 0.1 CPU hours. Require frozen 16 support shapes, all 392863 phase vectors per selected shape, exact arithmetic, literal worst-witness checks, preserved failures and no unbounded inference from positive samples. This is future work, not an execution recipe claimed completed here.\n\nEstimated read/spot time 10-15 minutes, no compute requirement. A valid generic union bound alone does not support the arithmetic hypothesis, an exponent, novelty priority or trusted acceptance. Reject any reading that treats the derived pair-atom examples or earlier pending results as verification of H2_13.
