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

This same-concept compact successor preserves the reader-first SGA surface from version 10.5281/zenodo.21628220. Fifty-nine predecessor files outside the three release controls are retained byte-identically; the controls are refreshed and the complete bounded SGA3 Expose IX checkpoint is added as a direct reader, direct editable master TeX, and grouped source/QA archive. The 36-page A4 Expose IX reader covers Sections 1-8, all 68 named formal units, 205 display/formula-or-diagram blocks, eight native diagrams, and the terminal bibliography and editor notes. It stops before combined-reader page 679 / Expose X. The PDF has 276 named destinations, 288 valid internal GoTo actions, 37 embedded non-Type3 fonts, and no raster XObjects. The grouped source archive has 68 exact non-directory members totaling 9,950,178 uncompressed bytes. It contains seven editable TeX files, the reader, all 36 reviewed renders, the reference-v2 graph, source and translation QA, audit receipts, provenance and rights notices, and recursive checksums. The graph partitions 644 candidates into 215 applied edges and 429 positive residuals, with zero pending actions. Two extracted-package audits and one manager-side exact replay passed; the latest manager report has SHA-256 CAF5E6351A49F1FB6FFEDEECA49270A4BA04F20C3CB5302B1973027DDB3E4860. The controlling witness is the Polo-Gille born-digital Expose IX PDF Exp9-8nov09.pdf, 32 pages, SHA-256 7C1E3D5B9D01AD01D0DD7B8B62045D012052E7890FB37ADC3E7934EBB5FD6FC3. It is not redistributed and is not recovered editor TeX. OCR is locator/drafting material only. Jacob C. Reinhold's Expose IX Markdown from jcreinhold/sga commit e7a259f3f8608ad3edf9bf6eead3fd504dd2d23e is credited comparison material, not authority or independent corroboration. Its declared CC BY 4.0 terms apply only to that contribution. No blanket license or rights clearance is asserted for the underlying French work, English reconstruction, editorial additions, or package as a whole. Machine-assisted contributors include OpenAI Codex / ChatGPT and Anthropic Claude under human direction. This is complete Expose IX, not complete SGA3. The current SGA3 surface has a cumulative reader through Expose IV plus standalone complete working readers for Exposes V, VI, VIII, and IX; Expose VII and Exposes X-XXVI remain absent. This successor updates only existing SGA concept 10.5281/zenodo.20410947. The SGA6 crop/provenance surface is unchanged, and live SGA6 work beginning at idx597 remains excluded.
