Arthur Cayley: Collected Mathematical Papers, Source-Checked Modern LaTeX Slice Readers

Dedicated Arthur Cayley author record for source-checked modern LaTeX slice readers, repaired diagrams, TeX sources, continuation manifests, and machine-readable progress indexes. This 2026-06-08 update adds the source-checked Volume I Paper 80 package for printed pp. 471--475, completing Sur quelques transmutations des lignes courbes, and the source-checked Volume I Paper 81 package for printed pp. 476--480, completing Addition au mémoire sur quelques transmutations des lignes courbes. The unitized index is refreshed through printed p. 480, and printed p. 481/source PDF p. 503 is boundary-checked as the start of Paper 82. The per-page materials include source scan witnesses, editable TeX, compiled PDFs, render-check PNGs, status notes, and machine-readable unit/formula/audit rows. The record also carries aggregate packages for recent Volume I source-checked pages and extracted high-value Pro/Claude salvage cores so that the Cayley DOI remains usable without repeatedly uploading multi-gigabyte raw provenance. Earlier repairs to Volume IV coefficient/Tschirnhausen tables and selected diagram/table pages in other volumes are retained. The current status is a substantial but still in-progress source-checked reconstruction: public readers and draft TeX cover far more than the strictly verified sequence, while the strict source-checked sequential layer is explicitly tracked page by page. Status at a glance. [########--] public reader/draft coverage: large rendered/draft coverage across the collected-papers volumes; [#####-----] strict scan-faithful sequential reconstruction: Volume I source-checked in indexed page units through Paper 81, printed p. 480, with other repaired areas tracked separately; [#########-] provenance: source scans, TeX chunks, repair packets, audit notes, and GitHub mirror preserved, while the largest raw provenance remains on the main preservation record.
