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 audit/repair packages for Bianchi differential-geometry and transformation-group texts. Latest update. Adds Bianchi_A2_core_p0001_0120_IT_EN_20260612.zip, a compact/core package for Lezioni sulla teoria dei gruppi continui finiti di trasformazioni extending the A2 Italian/English branch through source p0120. The package contains cumulative Italian transcription and English translation through p0120, current p0106-p0120 TeX/PDF, ledgers, render QA, logs, manifests, and source witnesses. Earlier large scan-heavy p0105 and repair packages remain provenance/backstop layers. 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 now has compact working coverage through source p0120, with OCR/image-analysis material treated as witness/locator evidence only. Quality note. These are working/source-witnessed drafts and repair packets, not certified critical editions. Readers should verify important formulas, theorem statements, matrix dots, prime marks, summation superscripts, and notation against the included source witnesses. Corrections and collaboration.
