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

This same-concept compact public-progress successor keeps current reader PDFs and primary editable TeX directly visible while grouping recursive source, diagrams, machine-readable reference ledgers, QA, bounded checkpoints, and predecessor material into twelve coherent ZIP archives. English readers, in sequence: complete-volume SGA 1 working reader; complete SGA 2 archive-curated R8; bounded SGA 3 through complete Exposé III; separate complete SGA 3 Exposé IV; complete-scope SGA 4 proper R2; SGA 5 R9; and complete terminal SGA 6. SGA 2 R8 remains the default preview. SGA 1 is complete in translation scope as a working reader. The current 262-page PDF contains 1,212 named destinations and 1,569 GoTo annotations on 233 pages. Its clickable infrastructure is real, but exhaustive theorem, equation, and bare-reference convention-v2 coverage has not yet been independently certified. The deeper audit remains in progress, and the audited bounded I.9.3 checkpoint remains preserved as predecessor evidence. SGA 3 remains incomplete. The 200-page cumulative Loop-1 reader covers the Editorial Notice, Introduction, and Exposés I-III. A separate 65-page reader covers complete Exposé IV. Exposé V is held pending corrected R3 release audit; Exposés VI-XXVI remain untranslated. PDF-derived diagrams remain through Exposé III, and native-diagram Loop 2 plus exhaustive-reference work remain open. SGA 4 proper is complete in translation scope. The 864-page R2 reader covers Exposés I-XIX including V bis and excludes SGA 4½. Source, build, PDF, font, rendering, rights-note, and privacy gates passed. R2 is published as a working reference-linked reader, not as exhaustive convention-v2 certification: its later package audit found incomplete or misclassified complete graph ledgers and a corrected build-page summary. R3 continues to find and link missed diagram references. SGA 2 R8, SGA 5 R9, and SGA 6 retain their current reference-linked status. SGA 4½ remains rights-held and absent. SGA 3 uses the current Polo-Gille reader as controlling witness; OCR is locator material only. Jacob C. Reinhold's jcreinhold/sga snapshot e7a259f3f8608ad3edf9bf6eead3fd504dd2d23e is credited comparison/drafting lineage, not authority. Reinhold states that his translation contribution is CC BY 4.0; that statement does not license the underlying French work or unrelated contributions. SGA 4 proper uses the frozen Orgogozo TeX snapshot at commit 71766d9. No new license grant is asserted for underlying French material, English translations, or third-party support files. 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.
