+# Stack v2 Sparse Python Classes 10k
+
+This is a 10,000-sample snapshot for Diffusion + Autoregressive hybrid code generation experiments.
+
+## Source
+
+The data is extracted from `bigcode/the-stack-v2-dedup`, Python subset. The extraction uses Stack v2 metadata as source of truth, groups candidates by `repo_name + revision_id`, fetches files with git partial fetch + sparse checkout, then applies AST-level class filters.
+
+## Splits
+
+- `train.jsonl`: 9,000
+- `val.jsonl`: 500
+- `test.jsonl`: 500
+- `all.jsonl`: 10,000
+
+## Record Format
+
+Each JSONL row is one Python class sample. Important fields include:
+
+- `prompt`: natural-language class implementation prompt
+- `skeleton`: class/method signatures and docstrings with `<|body_i|>` slots
+- `bodies`: list of method bodies without docstrings
+- `bodies_text`: body slots wrapped by `<|body_start_i|>` and `<|end_body_i|>`
+- `full_text`: skeleton plus body slots
+- `solution`: reconstructed class code
+- `source_repo`, `source_path`, `revision_id`, `blob_id`, `detected_licenses`: source metadata
+
+## Filters
+
+- 2 to 6 methods per class
+- every method has a non-empty docstring
+- every method body has 3 to 30 non-empty lines
+- reconstructed class parses as Python AST
+- tests/docs/examples/vendor/generated files are excluded by metadata/path filters
+- simple ClassEval/HumanEval contamination filters are applied
+
+Strict pyflakes is not used as a hard filter because isolated extracted classes often depend on module-level imports, constants, parent classes, or helper functions.
