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

This same-concept compact successor preserves 83 files from version 10.5281/zenodo.21642747 byte-identically, replaces the preferred SGA3 cumulative PDF and direct integration TeX, adds one grouped buildable source ZIP, and refreshes the three release controls. SGA1 remains the default preview. The preferred SGA3 reader now has 1,434 A4 pages and integrates the Editorial Notice, Introduction, Exposes I-XXIII and XXV-XXVI, the terminal bibliography, and the Tome III index. The four-page Tome III mathematical guide and Expose XXIV are explicit in-reader gaps. The object is current progress, not complete SGA3. The PDF has 9,246 named destinations, 4,541 valid internal GoTo actions, zero invalid or external actions, 64 font resources, zero Type3 fonts, and 142 raster image XObjects. Thirty-eight assembly and boundary pages passed direct visual review. The grouped source ZIP contains 867 safe members: an exact recorder-derived closure of 723 TeX files and 142 PNG assets plus manifest and validation controls. An independent four-pass rebuild matched all 1,434 extracted-text pages, decoded page streams, geometry, destinations, links, normalized fonts, and decoded image objects. Raw build logs, authority PDFs, OCR, and private paths are excluded. The 142 PNG assets are disclosed Loop-1 diagram witnesses needed for the current readable integration. They are not presented as final diagram-fidelity closure. Existing 600- and 1200-dpi evidence remains valid history and context; only 300-dpi-only approvals or identified defects reopen. Future diagram-final successors require native TeX and top-level lead authority comparison near 5000 dpi, escalating to 9000 dpi for ambiguity. The component-specific Polo-Gille authority PDFs are identity and page controls only and are not redistributed. Floris's pre-existing GPU OCR may be consulted read-only as locator or drafting evidence and was not regenerated. Jacob C.
