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.21631485. Fifty-six unrelated predecessor files are retained byte-identically. Nineteen formerly loose SGA3 component readers, editable masters, rights ledgers, and source/QA archives are preserved inside one byte-exact history ZIP and replaced on the landing surface by one cumulative working reader, one direct editable integration master, one history ZIP, one current integration-source ZIP, and refreshed release controls. The preferred SGA3 current-progress reader has 836 A4 pages and contains the Editorial Notice, Introduction, and Exposes I-IX, XI, and XIII. It includes explicit gap leaves for Exposes X and XII and ends before Expose XIV; Exposes XIV-XXVI are absent. It is therefore a substantial working reader, not a complete SGA3 translation, critical edition, or mathematical certification. The reader has 5,332 named destinations, 3,647 valid internal GoTo actions, zero broken internal GoTo actions, 173 outlines, 62 embedded fonts, and no Type3 fonts. Four XeLaTeX passes converged without hard errors, undefined references, duplicate destinations, missing glyphs, or overfull boxes. An isolated rebuild matched all 836 pages in content, text, geometry, links, and fonts. Expose VII is the latest readable repaired r5 body; its final detector/reference package remains unfinished. Expose XIII is a complete Loop-1 body whose source, formulas, and high-zoom diagrams were reviewed, while exhaustive reference/package closeout remains unfinished. These limitations are stated inside the reader and release controls rather than used to hide useful readable work. The history ZIP contains 21 exact members, including all nineteen superseded loose public SGA3 objects. The current integration-source ZIP contains 932 exact members. Across this successor there are 44 ZIP archives with 4,005 non-directory members and 387,806,305 uncompressed bytes. SGA1 remains the default preview; numeric filenames place the new cumulative SGA3 reader directly after SGA2. The controlling French source images and PDFs are not redistributed by the new integration archive. OCR and extracted text are locator or drafting witnesses only. Jacob C. Reinhold's jcreinhold/sga English lineage at revision e7a259f3f8608ad3edf9bf6eead3fd504dd2d23e is credited comparison/drafting material, not source authority; its author-declared CC BY 4.0 applies only to that contribution. Rights in the underlying French works and scans remain with their holders; no blanket license or rights transfer is asserted. Machine-assisted contributors include OpenAI Codex / ChatGPT and Anthropic Claude under human direction. This successor updates only existing SGA concept 10.5281/zenodo.20410947.
