SGA Translation Handoff, Batch 006 Cumulative Drafts

Linked satellite record for the Modern LaTeX Editions of Public-Domain Mathematics Manuscripts project. This record contains current rendered reader PDFs and a cumulative source/artifact ZIP for the SGA translation handoff. Batch 006 repairs the SGA 1-3 existing English snapshot renders into mathematical PDFs, extends the SGA 4 Expose I English draft through Lemma 9.13.1, and keeps worklogs, source extracts, validation notes, and render checks in the artifact ZIP. These are working drafts for continuation, not proofed final editions.
