# PG-19 Filtered Enriched

This dataset contains the PG-19 portion of the MonumentalSystems text pipeline, exported as cleaned JSONL shards.

## What is included

- `498` JSONL shard files under `data/`
- `299,410` chunk rows total
- the original filtered PG-19 portion
- the continued `0364-0573` PG-19 tail processed through the same cleaner, chunker, quality scorer, and DataTrove filtering path

## Row fields

Each row includes the original chunk text plus pipeline metadata such as:

- source coordinates (`source_ref`, `file_index`, `doc_index`, `chunk_index`)
- dedup fingerprints (`checksum`, `normalized_checksum`, `alnum_checksum`)
- quality and curriculum fields (`reading_level`, `complexity`, `difficulty`, `flesch`, `mtld`, `quality_pass`, `quality_reason`)
- semantic labels (`content_type`, `subject`, `subject_detail`, `title_hint`)

## Notes

- This export is PG-19-only, not the full text corpus.
- The continuation portion was exact-deduped against the existing PG-19 filtered corpus before export.
- `title_hint`, `subject`, and `subject_detail` are heuristic enrichment fields and should be treated as best-effort metadata rather than bibliographic ground truth.
