Luigi Bianchi: Modern LaTeX Working Editions and Source-Intake Witnesses

Dedicated Luigi Bianchi record for the Modern LaTeX Editions of Mathematics Manuscripts project. This record contains Italian source transcription, English translation working drafts, source scan witnesses, and auditfix packages for Bianchi's differential-geometry and transformation-group texts. Status at a glance. Volume I of Lezioni di geometria differenziale remains complete as a package-audited Italian/English working edition through source pdfpages 001-543. The A2 branch, Lezioni sulla teoria dei gruppi continui finiti di trasformazioni, remains in progress. OCR/image-analysis material is witness/locator evidence only; source scans and package audit ledgers control mathematical readings. Latest update. Adds Bianchi_A2_reaudit_p0001_0066_IT_EN_20260611.zip, a targeted re-audit correction package for the A2 cumulative Italian/English working draft through source p0066. It supersedes the previous p0001-p0066 cumulative files at two mathematical locations: source p0024 / printed p5 corrects the product-reduction example to (S_1S)(S^{-1}S_2)=S_1S_2, and source p0030 / printed p11 corrects the schematic M_1 matrix display to include the f_2 column and align the dotted structure with the source. The package rebuilds the Italian and English cumulative TeX/PDF and includes source witnesses, render diffs, page/formula/patch ledgers, and build diagnostics. This is a correction layer, not a continuation beyond p0066; section 13 remains deferred to the next work unit. Corrections and collaboration.
