# T706 research (checked in build, 2026-11-10) - Source conventions checked: https://arxiv.org/html/math/0202141v2 §1, equation (1.1), gives F_n as the untapered Möbius sum targeting -chi in L^2(0,infinity). https://arxiv.org/html/math/0011254v1 §1.2, (1.18), calls that sum S_n; its (1.19) F_n is dual and excluded here. - Kernel checked: https://arxiv.org/html/math/0306251v1 §4 defines the signed V(p,q), including modulus one; §9 Propositions 87 and 89 give A(1) and the rational-argument cotangent formula. Change-of-variable and error-bound derivations are in derivation.md. No unresolved normalization alternatives. - Live discovery: catalogue.json (702 records, including accessible drafts), screening.json, lookup.log, and T639–T642 documents/metadata are local evidence. No duplicate family. Lookup N=1 matches T642's N=2 (same rho_1 in a different context); N=2,3 return no matches. Related published tables T640 (kernel), T641 (minimum), T642 (taper), T639 (cotangent sum) remain unmodified. - Existing tags checked: number theory, functional analysis. The absent Nyman-Beurling criterion tag is recommended for this family and T639–T642; no published tables were retagged. Only existing tags are used in T706. - The 30-index consecutive selection and its noncanonical bound are justified in argument-selection.md. No continuous free parameter or quantile input. - Reused code: T641 generate.py, SHA-256 7e155af1d4a4963f874e0c536051c1cf0b7afd01e21b93d64a674c7fab8592c8; T641 checks.py, SHA-256 3a6ea0c72d6588b2fdda2d91a0414232f1d64092a5e928cd4121cc4d05798678. Only computational components are reused, with inspected derivations and fresh controls/calculations. Sibling values and verdicts are not evidence. - Provenance mapping checked against family-313/proposal.json and live wanted issue #273: proposal #313, contributes to #273 only. Both URLs were included in the first draft request; mathematical prose excludes request history. - Numerical evidence and source hashes: numerical-evidence.json; reproducible generator: generate.py; separate-route check: checks.py plus integral_kernel.py; resumable exact-endpoint kernels: kernel-checkpoints.jsonl. Archived instruction bundle: skill-manifest.json, verified local/live bundle d6661c2f21613524889fa3a57d3c95f8330344ca62e5a856211c08a282b7dbab. - No universal asymptotic or monotonicity assertion is inferred from this data. A fresh independent scientific and argument-selection verdict is outstanding.
