SGA 1-6: Compact English Working Readers, Reference-Linked Editions, and Audit Archives

This same-concept successor preserves 62 files from version 10.5281/zenodo.21680585 byte-identically. It replaces only the direct SGA3 R18 reader, its direct master TeX, its grouped source/history archive, and three release controls. SGA1 remains the default preview. The preferred SGA3 object is a 1,459-page English cumulative covering the Editorial Notice, Introduction, Exposes I-XXVI, the Tome-I index, the Tome-III mathematical guide, and the terminal index. R19 replaces all 62 Expose-III raster diagrams with lead-reviewed native TeX while preserving 4,467 valid internal GoTo actions. The direct reader contains the mathematics, diagrams, labels, and links rather than project-facing AI, production, source-status, or workflow commentary. The exact recursive source closure and the superseded R18 reader remain grouped in one ZIP. These are scholarly working translations and TeX editions, not critical editions, blanket rights clearances, mathematical certifications, peer review, final diagram-fidelity certification, or tagged-PDF accessibility remediation. No new license grant is asserted and historical Zenodo versions remain immutable.
