SGA and EGA High-Detail Source-Audit Image Worksets: Compute-Reuse Dataset

This compute-reuse dataset preserves 5,855 high-detail source crops generated during SGA 7 I transcription and diagram checking. They are tight regions from the publicly available source scan, not screenshots of the project reader. Two pixel ZIPs cover Exposes I, II, and VI-IX. A third compact ZIP contains the exact included-image manifest, the nine already-public duplicate dispositions, and the 5,902 ledgered targeted crops that were not present in the surviving local cache. Every included image decodes and every outer and member SHA-256 was read back independently. This is reusable source-audit evidence, not a transcription or mathematical certification. Reader PDFs remain on the separate SGA record.
