Data card — MBPP held-out decompilation benchmark 383 MBPP reference solutions compiled to Python 3.12 bytecode and paired with their source, with the original task_id restored on every row. Built 2026-08-04 by tools/build_mbpp_ood.py. Redistributable under CC-BY-4.0, provided NOTICES.md ships alongside. The set Rows 383 (400 candidates − 17 contaminated) Source google-research-datasets/mbpp, config full Licence CC-BY-4.0 task_id restored 383 /… See the full description on the dataset page: https://huggingface.co/datasets/BlazingCustoms/pybytecode-mbpp-3.12.
docs: disclose that the ast.unparse rewrite changes the compiled bytecode on 1 of 383 rows (src/00117.py, MBPP task_id 757) — co_code identical on all 383, set remains sound since reference and .pyc come from the same normalised string
fix: co_filename in all 383 .pyc was the build-machine absolute path; now src/NNNNN.py as bench.jsonl declares (oracle fingerprint excludes co_filename; 383/383 preserved)
