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

This same-concept compact successor adds the independently reviewed SGA 3 Exposé V R3 freeze3 working checkpoint to the reader-first release. Current reader PDFs and primary editable TeX remain directly visible; recursive source, diagrams, machine-readable reference ledgers, QA, bounded checkpoints, and predecessor material remain in 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 Exposés IV and V; complete-scope SGA 4 proper R2; SGA 5 R9; and complete terminal SGA 6. SGA 2 R8 remains the default preview. SGA 3 remains incomplete. The cumulative Loop-1 reader covers the Editorial Notice, Introduction, and Exposés I-III. Separate readers cover complete Exposés IV and V. Exposés VI-XXVI remain untranslated. Exposé V freeze3 has 273 targets, 333 linked edges, an exhaustive 4,328-candidate partition, 355 PDF destinations, and 411 valid GoTo actions. Its 66 temporary source-PDF-derived diagram PNGs still require native or faithful Loop-2 replacement. Freeze1 and freeze2 remain superseded history and are not current files. 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. Exhaustive theorem, equation, and bare-reference convention-v2 coverage has not yet been independently certified. SGA 4 proper is complete in translation scope. The 864-page R2 reader covers Exposés I-XIX including V bis and excludes SGA 4½. It is a working reference-linked reader, not exhaustive convention-v2 certification. SGA 4½ remains rights-held and absent. SGA 3 uses current Polo-Gille PDFs as controlling witnesses; 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, source-derived diagrams, or unrelated contributions. 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.
