Production-reconciled and exact-replay-idempotent lossless page layer for the 33 recovered legacy SMHS 1915(b) PDFs, preserving layout-aware extracted text, exact document and page-text hashes, word count, extraction method, quality flags, semantic hashes, canonical occurrence linkage, and M-2 lineage. It is physical citation evidence, not a structured operative-rule table.

**Grain.** One exact recovered PDF document SHA-256 and one-based physical page number.
