The Byte-Level Ledger of 1,003 Chapters: When an Overwrite Copy Met an Incremental Backfill, and a Converter Bit Its Own Tail

The owner copied 250 chapters back over the original paths and asked for verification that each matched its source novel, then the same HTML conversion, with not one character of content to be touched. A per-chapter byte hash — not a sample — compared copy against source: 1,003 chapters, 100 percent identical, zero cross-book contamination. What was called an overwrite copy was in fact an incremental backfill, with old chapters untouched. Then all three books were reconverted in full, 750/750 green: line-by-line zero difference against expected HTML recomputed from current sources, zero bare-asterisk leakage after tag stripping, and injected tampering always caught. A self-inflicted accident was also fixed along the way — a single-chapter trial run had overwritten a manifest into one line.
