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

This same-concept compact successor preserves 86 files from version 10.5281/zenodo.21645478 byte-identically, refreshes three release controls, and adds a complete bounded SGA3 Expose XIII checkpoint as a direct reader, direct editable master TeX, and grouped source/QA ZIP. SGA1 remains the default preview. The new 32-page A4 reader covers Expose XIII only: Sections 1-6 through terminal Remarks 6.6(c), corresponding to Polo-Gille local pages 1-30 / combined-reader pages 805-834, with a hard stop before Expose XIV / combined page 835. It is not a complete SGA3 reader. The reader has 274 named destinations, 494 valid internal GoTo actions, zero broken or external actions, 32 embedded font resources, no Type3 fonts, and no raster image XObjects. Reference-v2 R9 closes 166 targets and 899 candidates as 453 active edges plus 446 residuals, with 468 applied actions and zero remaining. All seven diagrams are native editable tikz-cd source. The session lead compared every current diagram directly to authority at 5000 dpi; no unresolved ambiguity required 9000-dpi escalation. The ZIP contains target-only high-zoom crops and no authority PDF or authority crop. Four fresh archive XeLaTeX passes completed. The producer and independent outputs match on all 32 extracted-text pages, decoded content streams, link sets and rectangles, named destinations, object counts, and 150-dpi rendered pixels. The exact 85-file handoff and its self-excluding 83-row manifest replay without error. The controlling witness is Polo-Gille Expo13.pdf, 30 pages, SHA-256 24735CAFA57291A71C603712C0588358977856D5971503E6E73F3F2E40A70798. It is not redistributed.
