Emmy Noether: Modern LaTeX Drafts and English Translation Working Drafts

Dedicated Emmy Noether record for the Modern LaTeX Editions of Mathematics Manuscripts project. This version adds a compact R123 German salvage package while preserving the existing R120/R121/R122, R122 rollup, and Slavic/Interslavic transfer surface. New R123 salvage package. This version adds Noether_R123_Salvage_P12_P13_P16_P20_P39_WebDrop_20260624.zip. The package salvages the failed web-session R123 work and merges it with local source-certified fixes. It includes a 457-page German cumulative candidate, a quick inspection slice, TeX/PDF, source witnesses for the touched loci, compile logs, diffs, and machine-readable ledgers. Targeted fixes represented. The R123 package integrates targeted German cumulative fixes for P12 formula (11) terminal punctuation, P13 footnote/index/Heun wording, P16 alpha-coefficient notation, P20 formula tag (12), and P39 pp.189-194 source-fidelity/title/author/source-layout refinements. It intentionally includes P12/P13 as well as P16/P20/P39, so for these touched loci it supersedes both the compact P12/P13/P16/P20 rollup and the incomplete failed R123 transcript. Slavic/Interslavic package already present. The record also preserves Noether_Slavic_ZenodoDrive_Transfer_CurrentSources_20260623T1920Z.zip, a Ukrainian, Russian, Interslavic Latin, and deterministic Interslavic Cyrillic translation-lane source-transfer package. Its archive value is not only reader PDFs: TeX sources, logs, glossaries, terminology/register notes, segment spines, manifests, source-control notes, authority-download metadata, and Latin/Cyrillic conversion tooling are part of the linguistics-and-mathematics apparatus. Status and limits. The R123 package is a source-certified salvage for the listed loci only. It is not a critical edition, not whole-corpus mathematical certification, not full page-by-page certification of the Noether corpus, and not downstream multilingual propagation. The R122 rollups remain useful provenance but are superseded by R123 where the touched loci overlap. The Slavic/Interslavic transfer still needs reconciliation against the latest German source-audit queue before canonical promotion. Subtle formula errors, scan-reading errors, apparatus drift, and cross-language synchronization errors may remain. Verify important equations, tables, theorem statements, diagrams, and unusual notation against source witnesses before citation-critical use. Corrections and collaboration.
