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

Dedicated Luigi Bianchi record for the Modern LaTeX Editions of Mathematics Manuscripts project. It contains cumulative Italian and English reader editions, controlling scan witnesses, and reproducible source/QA packages for Bianchi's differential-geometry and transformation-group texts. A1 Volume I update (2026-08-12). The top-level A1 files now have human-readable names and contain the cumulative Italian and English editions of Lezioni di geometria differenziale, Volume I, together with the exact 543-frame source scan and a deterministic sources/QA supplement. The Italian edition restores three symbols proved directly from the scan and otherwise preserves printed source errors literally. The English edition carries the same symbol restorations, five explicitly labelled mathematical corrections, and one explicitly exposed unresolved source conflict. Figure 8 now uses a direct, untouched authority-pixel facsimile because the previous TikZ redraw omitted the printed D-C'-E chord. Evidence boundary. Both A1 PDFs were produced twice in clean isolated two-pass builds with byte-identical results, zero recorded TeX warnings, and fully embedded fonts. Every output page was rendered and reviewed at page scale, and every changed mathematical locus has individual direct-authority and final-output evidence, including 5,000-dpi-equivalent inspection crops. This is a source-witnessed working edition, not a critical edition and not yet a full symbol-by-symbol replay of all 543 scan frames. The direct Italian-to-Simplified-Chinese edition is the continuing exhaustive QA pass and is not yet deposited in this version. A2 unchanged. Lezioni sulla teoria dei gruppi continui finiti di trasformazioni remains partial through source p0135 in Bianchi_A2_core_p0001_0135_IT_EN_20260613.zip. All A2 and historical provenance/backstop files in the preceding version are retained unchanged. Corrections and collaboration.
