Éléments de géométrie algébrique (EGA): Canonical French and Standalone English Editions

2026-08-08 EGA I 2.4.5 corrected-layer / standalone-English R191 checkpoint. This same-concept successor maintains exactly two independent cumulative editions. The canonical diplomatic French reader and master remain admitted through EGA II printed p.24. The independent standalone English EGA 0–IV reader now includes one verified retroactive mathematical correction. French and English retain separate masters, sources, manifests, QA, and reversible ledgers; there is no bilingual, paired, parallel, side-by-side, interleaved, or combined reader. Printed EGA I 2.4.5 correctly classifies local homomorphisms A to K, then falsely extends the conclusion to all morphisms Spec(K) to Spec(A). For A=k[t]_(t) and K=k(t), inclusion lands at the generic prime (0), not the closed point (t). Diplomatic French preserves and catalogues the authorial error. Corrected English restricts the sentence to morphisms whose unique point maps to the closed point. REF4 preserves and explicitly reverses the earlier p.102 no-defect decisions; R191 records the exact R190 preimage, byte offset, replacement, inverse, and complete 127-file replay. Adjacent 2.4.6 already gives the correct all-points formulation, so no dependent statement changed. The standalone English reader remains 1,345 pages and physical p.298 passed visual QA. The French reader remains 159 pages and is the default preview. The prior EGA II p.24 correction k > -a to k >= a is retained. 03_INDEX.md is non-reader semantic metadata. Canonical French EGA 0–IV remains incomplete; after this public closure, the next direct-NUMDAM cursor is EGA II printed p.25, continuation of Proposition 2.2.5. Earlier versions and the 80 inherited files remain immutable historical evidence. Start with 00_FR.pdf or 00_EN.pdf.
