SGA 1-6: English Readers, French Texts, and TeX Archives

SGA1 R2 source correction: the complete 262-page reader, direct master TeX, and leading SGA1-6 cumulative PDF/buildable-TeX bundle are retained byte-for-byte. The grouped SGA1 source/history archive is replaced by its privacy-clean R2 projection; five machine-local paths were sanitized without changing the mathematical reader or source. SGA1 update: the direct SGA1 reader is now the complete 262-page reference-v2 successor with 2,151 named destinations and 1,600 resolved internal links. The leading ZIP contains the cumulative SGA1-6 PDFs and each reader's complete buildable TeX closure. Start here: the first file is one clean ZIP containing the current cumulative English reader PDF for each of SGA 1 through SGA 6 together with its complete buildable TeX closure. The same six reader PDFs and master TeX files remain directly accessible immediately afterward. English readers for SGA 1 through SGA 6 are listed first in numerical order. Available French texts and editable TeX masters follow; supplementary source and historical files are grouped in ZIP archives. The preferred SGA3 English reader is the R28 successor: 1,470 A4 pages containing the Introduction, Exposes I-XXVI, the Tome-I subject index, the Tome-III mathematical guide, and the terminal index. It has 13,132 named destinations and 12,344 valid internal GoTo actions; all 3,744 mapped stable targets replay to their intended page and coordinates. The direct readers present the mathematical editions and genuine historical scholarly apparatus. Editable sources, provenance, checksums, and release controls are available in grouped archives. Earlier Zenodo versions remain immutable history. These are working English translations and TeX editions, not critical editions or rights determinations. They do not transfer rights in the underlying French works.
