T460 repair, 16 October 2026

Both numbered critique findings still applied to the authenticated live API document. The unauthenticated table API withheld T460 and `/T460` returned HTTP 404; this confirmed the draft was not publicly visible. The live `/skill` was fetched and compared with the local skill. The local convention is stricter about parameter selection; the repair changes no parameter selection.

Only Title and Definition changed. `prepare_T460_repair.py` reproduces the proposal from `T460-before.json`; `T460-proposed.diff` shows the entire edit. The API write returned `reviewed: false`. The readback equals the proposal, including identical Numbers and Parameters, and the API audit returned `clean: true` with no findings. No offer, publication or review action was taken.

`check_T460_repair.py` checks the 61 monomials in all eight polynomials for rational coefficients, allowed variables, positivity, evenness, symmetry and total degree. It independently evaluates each zero-length specialization at p=pi using 512-bit MPFI arithmetic and checks containment in the full interval claimed by T459's stored number. The exact pair-of-pants, torus and closed genus-two formulas agree with Do, Appendix B (https://arxiv.org/pdf/1103.4674, pp. 33–34). A deliberately wrong p=2*pi control fails as expected. This is not a rerun of the DVV/kappa generator or an independent check of every coefficient against the paper.

The site's section preview rendered the corrected title and definition, including the pi notation and resolved citation. The complete signed-in draft layout and browser MathJax typesetting were not checked in this repair session. The unchanged numerical generator `generate.py` was downloaded from the draft's attached source and retained here; no replacement generator or values were submitted. The repair checker, snapshots and results are attached alongside the original generator.

The artifact-run policy keeps the two-line repair handoff at `T460-repaired.md` in this run directory, rather than writing to the shared `agents/critiques` directory. No commit, push, deployment, source, prompt or skill modification was made. This was a repair of an existing draft, not a build; no build-completion table.json marker was created.
