 ## Dataset Description
 
-This dataset provides filtered, quality-controlled Python source code in multiple configurations: the original English, three keyword-swapped variants (Chinese, Spanish, Urdu), a blended native+transpiled mix, and strictly native Chinese code. The source data is drawn from [bigcode/the-stack-dedup](https://huggingface.co/datasets/bigcode/the-stack-dedup) (Python subset), filtered for quality using the following criteria:
+This dataset provides filtered, quality-controlled Python source code in multiple configurations: the original English, three keyword-swapped variants (Chinese, Spanish, Urdu), a blended native+transpiled mix, strictly native Chinese code, and a model-translated set in which an LLM translates the full source (identifiers, strings, and comments, not just keywords). Python source for Conditions 1, 2, and 5 is drawn from [bigcode/the-stack-v2-dedup](https://huggingface.co/datasets/bigcode/the-stack-v2-dedup) (Python subset) for the current Phase 3 configs; the legacy `phase-2-the-stack-v1-*` configs are sourced from [The Stack v1](https://huggingface.co/datasets/bigcode/the-stack). Conditions 3 and 4 additionally draw on natively-authored code (see those conditions below). Source files are filtered for quality using the following criteria:
 
 - AST-valid Python only (must parse without errors)
 - Permissive licenses only (MIT, Apache-2.0, BSD, etc.)

 ## Limitations
 
-- **Source bias**: The Stack Dedup skews toward popular, well-starred GitHub repositories, which may not represent the full diversity of Python code in the wild.
+- **Source bias**: The Stack skews toward popular, well-starred GitHub repositories, which may not represent the full diversity of Python code in the wild.
 - **Keyword-only transpilation**: Legesher translates Python reserved words (keywords, builtins, exceptions) but leaves comments, docstrings, string literals, and variable/function names in their original language (typically English). This means condition-2 code is a hybrid of translated keywords and English identifiers.
 - **Token count variation**: Transpiled code may have different token counts than the English original due to multi-byte characters (especially for Chinese and Urdu), even though the code structure is identical.
 - **Single programming language**: Currently limited to Python. Results may not generalize to other programming languages.
 - **Condition 4 scope**: Native Chinese code is limited to publicly available sources (The Stack, Wenyan, Program-in-Chinese, Qi, Mulan) and may not represent the full spectrum of Chinese-language programming.
+- **Condition 5 is raw model output**: The `condition-5-*` configs contain prompt-leakage contamination -- translator-model preamble text, JSON wrappers, and explanation commentary leaked into string literals and identifier names, in AST-valid and AST-invalid rows alike. Cleaned configs will be published separately. See the note at the top of this card.
