Luigi Bianchi: Modern LaTeX Working Drafts 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 differential-geometry and transformation-group texts. Status at a glance. Volume I of Lezioni di geometria differenziale remains represented 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_cont_p0001_0077_IT_EN_20260612.zip, continuing the A2 Italian/English working stream through source p0077. It restores the visible §13 heading and opening sentence from the lower part of source p0066, covers the p0066-p0077 continuation through the end of §16, starts Chapter II / §17, and sets the next continuation point at p0078 inside §17. The package includes Italian and English current/cumulative TeX/PDF, current and cumulative source witnesses, audit notes, build summary, English parity check, and queue/metrics files. Its audit explicitly says this pass is not a reassertion that every earlier p0001-p0065 handwritten symbol has been recursively rechecked. Corrections and collaboration.
