Seminaire de Geometrie Algebrique (SGA): English Translation Working Drafts

Public SGA working-translation record for the Modern LaTeX Editions of Mathematics Manuscripts project. This backfill version keeps the current reader-facing PDFs, source-scan witnesses, and compact source ZIPs, while adding the missed repair019 package that should sit between repair018 and repair020. Status at a glance. This is a substantial working-draft and repair record, not a globally certified complete edition or critical edition. Repair019 closes the explicit early SGA5 French diagram cluster raised by visual sweep: source/current p030, p031, p038, p046, p047, and p048 are dispositioned for that pass. Repair020 continues the SGA5 French diagram-level pass around source pp.083-086 and p102, including Proposition 2.3, §2.4-2.5, and the diagram (4.4.0) cube repair. SGA6 French is carried forward unchanged in these packages. SGA5 English remains an unsynchronized carry-forward branch. SGA6 and SGA7 material should still be read with explicit working-draft/compression caveats unless a specific packet declares narrower source-checked coverage. File-surface curation note. The SGA record is at Zenodo's 100-file ceiling. This version removes an older aid-only witness ZIP and an obsolete repair018 summary JSON from the latest file surface in order to add repair019 and its summary. The removed files remain preserved in earlier Zenodo versions; repair018 itself remains attached. Filename warning. Older filenames containing words such as Complete, Strict, or Source-Checked are legacy package names and are not current global certification claims. Source-witness and aid ZIPs are locator/check layers, not textual authority by themselves. Corrections and contributions.
