# Plaincode CNL 100k

This dataset is generated with Plaincode by streaming Python source files, projecting each accepted Python module/function into the current controlled-natural-language surfaces, and enforcing strict exact Python roundtrip proof for every emitted language. The public row schema is one wide row per accepted Python source: source first, then English/Spanish/French/Mandarin/Hindi/Portuguese CNL columns, then selected metadata.

## Included surfaces

- Python source
- English CNL (`en`)
- Spanish CNL (`es`)
- French CNL (`fr`)
- Portuguese CNL (`pt`)
- Mandarin CNL (`zh`)
- Hindi CNL (`hi`)

## Acceptance gate

A row is accepted only when every requested CNL surface reverses back to the exact original Python bytes through Plaincode proof. The proof details are used as an internal gate, but they are not stored in each public JSON row.
## Schema

Each row is ordered for readability and training use:

1. `source`: the original Python source
2. `english_cnl`: English Plaincode CNL
3. `spanish_cnl`: Spanish Plaincode CNL
4. `french_cnl`: French Plaincode CNL
5. `mandarin_cnl`: Mandarin Plaincode CNL
6. `hindi_cnl`: Hindi Plaincode CNL
7. `portuguese_cnl`: Portuguese Plaincode CNL
8. `ids`: row/source/run identifiers
9. `roundtrip_python_by_language`: exact reconstructed Python per CNL language
10. `source_stats`: source hash/count/compile summary
11. `source_metadata`: upstream source metadata where available
12. `semantic_family`: broad code-shape label
13. `engine`: Plaincode generation metadata
14. `row_sha256`: stable hash for the public row

## Intended use

Training/evaluating semantic projection, code-to-CNL, CNL-to-code, multilingual controlled-language alignment, and exact roundtrip experiments.

## Source/license note

Rows retain source metadata where available, including license fields exposed by upstream datasets. The default generator configuration prioritizes permissive-ish Python source configs. Review upstream licenses before redistribution or commercial use.
