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

This same-concept compact successor replaces the SGA 4 proper working r2 surface with the independently certified reference-v2 r7 reader, editable master, exact source ZIP, and QA ZIP. Current readers and primary editable TeX remain directly visible; recursive source, machine-readable ledgers, QA, bounded checkpoints, and predecessor material remain grouped. SGA 4 proper r7: the 864-page reader covers Exposes I-XIX including V bis and excludes SGA 4half. The English translation edition remains marked r2 on its title page; r7 identifies the certified reference and release package. Its convention-v2 graph has 8,701 candidates with exhaustive dispositions, 3,388 targets, 6,114 edges, 9,421 PDF destinations, 6,800 valid GoTo actions, two URI actions, and 183 outlines. The source ZIP closes the exact 300-file build tree. The QA ZIP carries graph, set-relation, build, all-page equivalence, and visual-review evidence. Rejected or incomplete SGA 4 r4, r5, and r6 packages are not current files. The prior r2 working surface remains immutable in predecessor version 10.5281/zenodo.21509314. SGA 4half remains absent. Other readers: SGA 1 is complete in translation scope as a working reader with substantial but not exhaustively certified links. SGA 2 R8 remains the default preview. SGA 3 has bounded working readers through complete Expose V but remains incomplete; Exposes VI-XXVI are untranslated and Expose V retains 66 temporary Loop-1 diagram obligations. SGA 5 R9 and the complete layered terminal SGA 6 reader remain direct. SGA 4 proper uses the frozen Orgogozo TeX snapshot at commit 71766d9 as French authority. No new license grant is asserted; rights remain with their respective holders. Machine-assisted contributors include OpenAI Codex / ChatGPT and Anthropic Claude under human direction. These are modern working editions and translations, not critical editions, mathematical certifications, independent human peer review, blanket rights determinations, or accessibility certifications. All predecessor versions remain immutable. This successor updates only existing SGA concept 10.5281/zenodo.20410947.
