| # 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 language per row: one accepted Python source emits sibling rows for en/es/fr/pt/zh/hi linked by python_source_id. |
|
|
| ## 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: |
|
|
| - `sha_exact_ok == true` |
| - `char_exact_ok == true` |
| - `byte_exact_ok == true` |
| - `exact_ok == true` |
| - `reverse_ast_ok == true` |
| - `reverse_compile_ok == true` |
|
|
| The public CNL fields must not contain private CST/proof transport markers. |
|
|
| ## Schema |
|
|
| Each row is ordered for readability and training use: |
|
|
| 1. `source_code`: the original Python source, first in the JSON object |
| 2. `cnl`: `{"language": "en/es/fr/pt/zh/hi", "text": "..."}` |
| 3. `ids`: row/source/run IDs linking sibling rows from the same Python source |
| 4. `cnl_siblings`: sibling language list/count and all-language strictness flag |
| 5. `roundtrip`, `proof`, `strict_exact`: reverse/proof data |
| 6. `source_stats`, `source_metadata`, `semantic_family`, `engine`, `row_sha256`: inspection metadata at the bottom |
|
|
| The data shard writer preserves JSON key order. It does not sort keys alphabetically. |

|
| ## 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. |
