+# code2lora-data-ood — post-cutoff OOD evaluation split
+
+Out-of-distribution evaluation slice: commits from repositories whose first
+release is **strictly after** the Qwen2.5-Coder pretraining cutoff. Used to
+isolate cross-repository transfer from training-set memorisation.
+
+## Layout
+
+```
+commits.parquet    per-commit metadata + diff/repo-state embeddings
+qna.parquet        per-assertion rows (prefix, target, lineno, ...)
+```
+
+Both files share the same `(repo_id, commit_index, commit_sha)` key, so a
+left join on those three columns reconstructs the per-commit QnA bundle.
+
+## Schema
+
+`commits.parquet` matches `code2lora/code2lora-data-commits/commits/*.parquet`.
+`qna.parquet`     matches `code2lora/code2lora-data-snapshots/qna/*.parquet`.
+
+## Companion datasets
+
+* `code2lora/code2lora-data-commits`   in-distribution per-commit dataset
+* `code2lora/code2lora-data-snapshots` static-snapshot variant
