Claude Audits Quantum Gravity An AI re-derived a published one-loop quantum gravity calculation step by step. It found a sign error and a missing term, and confirmed the physical conclusion. The paper: E. O. Kahya, Auditing a quantum gravity calculation with an AI model: corrected scalar self-mass and unchanged late-time mode functions during inflation (submitted to arXiv, 2026). PDF · LaTeX source This repository re-derives, step by step, a published one-loop quantum gravity calculation during inflation: the graviton correction to a massless, minimally coupled scalar on de Sitter space ( Paper I , Phys. Rev. D 76, 124005 (2007)), and its use in the scalar’s late-time field equation ( Paper II , arXiv:0710.5282). The re-derivation was carried out with Claude (Anthropic’s AI model, Claude Opus 5.5) as a checking tool. It was published by E. O. Kahya, one of the authors of both papers. Each step, from the Feynman rules (I.6)–(I.8) to the renormalized self-mass (I.167) and the late-time analysis of Paper II, was derived again from the inputs stated in the papers, keeping the dimension $D$ general wherever the paper does, and cross-checked with independent SymPy/mpmath code. (The bookkeeping tables of Paper I’s appendix were audited rather than redone; see Limitations .) Every difference from the printed papers is classified: 4 substantive findings (S1–S4), 6 finite errors absorbed into counterterms (B1–B6) and 23 typographical errors (C1–C23) . The complete list of findings give
