Elements de geometrie algebrique (EGA): French Originals, English Working Readers, and Source Archives

Start here: the first file is one compact ZIP containing the five current cumulative English reader PDFs and their complete buildable TeX closures. The same five readers and their master TeX files are directly accessible immediately afterward. This same-concept successor presents current reference-v2 readers for complete EGA 0 through Section 13, complete EGA I, complete EGA II, and the complete published EGA III text through Section 7.9.14. EGA IV remains an explicitly partial working reader through Sections 1-10. The direct master TeX files are followed by four coherent source/QA ZIP archives, concise status and identity controls, the NUMDAM French originals, and four retained historical source archives. Stale loose readers and superseded per-reader packages remain available in immutable predecessor versions rather than cluttering this current landing surface. These are scholarly working and custody materials, not critical editions, peer-review or mathematical certifications, rights determinations, whole-EGA completion claims, or tagged-PDF accessibility remediation. No blanket license or transfer of underlying rights is asserted. EGA IV source-image witnesses: this successor adds two ZIP archives containing 343 actual scan-derived PNG witnesses from the publicly available NUMDAM EGA IV Part 4 scan already downloadable on this record. They preserve 600/1800-dpi full-page and overlapping-band images plus targeted 5000/9000-dpi ambiguity crops. Images through printed page 78 correspond to completed source-alignment review; the 32 images for printed pages 79-86 are clearly marked as prepared witnesses without a completed-alignment claim. English-reader screenshots are excluded. Every member has page, dimensions, resolution, SHA-256, linked TeX, and QA disposition metadata. EGA IV source-image witnesses through printed page 105: this successor adds one ZIP containing 76 actual scan-derived PNG witnesses from the publicly available NUMDAM EGA IV Part 4 scan already downloadable on this record. It preserves one 600-dpi full page and three overlapping 1800-dpi bands for each printed page 87-105. Pages 87-104 are bound to the producer alignment ledger and checkpoint r29; page 105 is explicitly marked as the active continuation rather than alignment-closed. English-reader screenshots are excluded. Every member has page, dimensions, resolution, SHA-256, linked TeX, and QA-disposition metadata. EGA IV source-image witnesses through printed page 118: this successor adds one ZIP containing 52 actual scan-derived PNG witnesses from the publicly available NUMDAM EGA IV Part 4 scan already downloadable on this record. It preserves one 600-dpi full page and three overlapping 1800-dpi bands for each printed page 106-118. Pages 106-111 are bound to producer checkpoint r31; pages 112-118 are explicitly marked active-continuation witnesses rather than alignment-closed text. English-reader screenshots are excluded. Every member has page, dimensions, resolution, SHA-256, linked TeX, and QA-disposition metadata. EGA IV source-image witnesses for printed pages 119-127 and 185-225: this successor adds two ZIPs containing 178 actual scan-derived PNG witnesses from the publicly available NUMDAM EGA IV Part 4 scan already downloadable on this record. Archive 88 provides one 600-dpi full page and three overlapping 1800-dpi bands for each printed page 119-127, bound to producer checkpoint r33. Archive 89 provides 5000-dpi tiled source crops for pages 185-195 and 1800-dpi full-page renders for pages 196-225, bound to producer checkpoint r12. The gap at printed pages 128-184 remains explicit. English-reader screenshots are excluded. Every member has page, dimensions, resolution, SHA-256, linked TeX, and QA-disposition metadata. EGA IV source-image witnesses for printed pages 128-155 and 226-281: this successor adds two ZIPs containing 169 actual scan-derived PNG witnesses from the publicly available NUMDAM EGA IV Part 4 scan already downloadable on this record. Archive 89a provides one 600-dpi full page and three overlapping 1800-dpi bands for each printed page 128-155. Pages 128-149 are bound to producer checkpoint r36; pages 150-155 are explicitly marked as prepared continuation witnesses. Archive 89b provides one 1800-dpi full page for each printed page 226-281 plus a targeted formula crop. Pages 226-271 are bound to producer checkpoint r14; pages 272-281 are prepared continuation witnesses. Actual image coverage is now continuous on pages 5-155 and 185-281; the remaining page 156-184 gap is explicit. English-reader screenshots are excluded. Every member has page, dimensions, resolution, SHA-256, linked TeX, and QA-disposition metadata. EGA IV Sections 16-18 and source-image witnesses through printed page 184: this successor adds a self-contained ZIP with the complete bounded 136-page source-aligned English working reader for Sections 16-18 and its editable TeX closure. It also adds a separate ZIP containing 116 actual scan-derived PNG witnesses for printed pages 156-184 from the publicly available NUMDAM EGA IV Part 4 scan already downloadable on this record: one 600-dpi full page and three overlapping 1800-dpi bands per page. The images are source evidence, not screenshots of the English reader. Every image has page, dimensions, resolution, SHA-256, linked TeX, and QA-disposition metadata. Together with the predecessor archives, actual source-image coverage is continuous from printed page 5 through page 281. The Sections 16-18 reader stops before Section 19. It does not claim a complete cumulative EGA IV reader: Sections 11-15 are not yet integrated into this source-aligned line, and Sections 19-21 remain active work. EGA IV source-image witnesses through printed page 332: this successor adds one ZIP containing 51 actual scan-derived full-page PNG witnesses for printed pages 282-332 from the publicly available NUMDAM EGA IV Part 4 scan already downloadable on this record. Each page is rendered at 1800 dpi and bound to physical/printed page, dimensions, SHA-256, linked editable TeX, and QA disposition. The images are source evidence, not screenshots of an English reader. Together with archives 84-89c, the public source-image surface contains 985 actual images and covers printed pages 5-332 continuously. The image archive does not claim that a cumulative EGA IV Sections 1-21 reader has been integrated or independently certified. The direct cumulative EGA IV reader remains Sections 1-10; archive 02e remains the separate bounded Sections 16-18 reader.
