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

Dedicated Luigi Bianchi author/work record. The record contains a complete package-audited modern working edition of Lezioni di geometria differenziale, Volume I, plus source-intake and high-quality working-edition material for Lezioni sulla teoria dei gruppi continui finiti di trasformazioni. Anno 1902-1903 (A2). Volume I status. Italian source transcription and corrected English translation reading streams are complete through source pdfpages 001-543, with source-scan witness, TeX, ledgers, render checks, and the 2026-06-09 auditfix package. This remains a package-audited working edition, not a final critical edition. A2 high-quality branch current in this version. This version adds reader-facing English and Italian PDFs plus Bianchi_A2_HQ_p0001_0066_IT_EN_20260610.zip. The HQ branch now covers source pages 0001-0066. The newest tranche covers source pages 0046-0066, sections 7-12; the lower-page section 13 opening on p0066 is deliberately deferred. The next continuation point is section 13 at the p0066/p0067 boundary. A2 correction/status caveat. The high-quality branch supersedes the earlier low-detail intake witness only for ranges covered by the HQ branch. A2 is not complete: this covers 66 of 731 source pages, about 9.03 percent of the available source. OCR and image-analysis outputs are witness/locator/check layers only; the promoted body transcription was read visually from high-quality source images and should still be checked against the scans for citation-critical use.
