SGA 1-7: English Readers, French Texts, Spanish SGA 5, TeX Archives, and SGA7 Source Transcriptions

SGA 1-7 mathematical reader and source archive This record preserves the current SGA reader corpus, editable sources, build closures, provenance, and cross-volume reference controls. It includes the English reader corpus for SGA 1 through SGA 7 II (including SGA 4 1/2), retained French source surfaces, and a complete Spanish working translation of the contents published in SGA 5 / Lecture Notes in Mathematics 589. Start here: the first file is the complete English SGA 1-7 II reader/source ZIP. The default preview is 00_SGA_1-7II_English_Global_Reader.pdf, the 4,179-page cumulative English reader. Clean standalone English readers and their TeX/source closures follow. Spanish SGA 5: SGA5_ES.pdf is the directly readable 326-page Spanish reader, sga5_es.tex is its editable master, and SGA5_ES_376U_326P_91A644AB_2B69F774.zip preserves all 408 source, unit, evidence, script, manifest, and control files. The checkpoint covers all contents actually published in SGA 5: front matter; Exposes I, III, III B, V, VI, VII, VIII, X, XII, and XIV=XV; and both terminal indexes. Its exact gate records 376 source units and 401 terminology decisions. The reader PDFs contain mathematics and source-era apparatus, not archive workflow notes or AI explanatory footnotes. These are source-reconciled working translations and preservation artifacts, not critical editions, native-language certifications, mathematical peer review, or blanket license grants. Rights in underlying works remain with their rightsholders; public preservation does not claim a transfer of those rights. Exact human-readable logbooks, continuation, decisions, reversals, claim boundaries, manifests, and validation surfaces are kept directly accessible or inside the complete transports. Earlier noncanonical Spanish SGA 5 generations remain immutable version history and are superseded by the complete checkpoint here.
