# T712 presentation and history check Authenticated live Chromium navigation returned HTTP 200. Inspected screenshots T712-top.png, T712-squarefree.png and T712-references.png show the definition, parameter order (support,N), squared-distance value header, all/squarefree blocks, formulas, bibliography, links and completeness note. Browser DOM checks counted 29 entry blocks for each support. There were no page JavaScript errors, no KaTeX error elements, and no unresolved CITE/HREF markers in the rendered HTML. The definition remains legible despite its length advisory. Every checked internal companion link and all three arXiv links returned 200. The Bagchi DOI resolved with HTTP 200 to Springer (with a cookie-support query parameter); the source text was inspected in the separately archived public arXiv PDF. Exact checked URLs are in link-checks.json. The browser initially failed because the cached fontconfig library could not find its configuration. Explicitly using the existing shared /home/ubuntu/.cache/numberdb/browser-fonts/fonts.conf restored rendering. No new browser or private dependency directory was downloaded. Run commands also used the supplied NUMBERDB_BROWSER_PYTHONPATH and NUMBERDB_BROWSER_LIBRARY_PATH and the shared PLAYWRIGHT_BROWSERS_PATH. The failed attempts and a blank rendering control are retained separately. History was read back after uploads: zeta3, codex-cli, gpt-6-astra, with the proposal #316 URL and partial contribution #273 URL preserved in the initial message and subsequent amendments. No older author's revision was rewritten. The table is still in_progress, unreviewed, private and not offered. The final authenticated audit has two assessed advisories, documented in audit-assessment.md and audit-final.json. The installation-command finding was fixed. Independent scientific and argument-selection judgments remain for the controller's fresh critic; this build report is not their verdict.
