**License of sources:** Public domain (US) via Project Gutenberg  
**Mixture:** Character-concatenated train slices of the listed PG texts (headers stripped).  
**Full downloads** retained under `data/raw/*.full.txt` with sha256 in `sources.json` for verification against URL content at fetch time.  
**Train slice** is a prefix of cleaned text to keep Mac nano training tractable — this limitation is a **tombstone**, not hidden soft tissue.
