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.21672742 byte-identically. It replaces only the direct SGA3 R17 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 1,470-page English cumulative covering the Editorial Notice, Introduction, Exposes I-XXVI, the Tome-I index, the Tome-III mathematical guide, and the terminal index. R18 replaces all 25 Expose-I raster dependencies with native TeX while preserving all 4,591 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 The exact recursive source closure and the superseded R17 reader remain grouped in one ZIP.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.
