+# code2lora-data-commits — per-commit dataset (GRU)
+
+One parquet row per (repository, kept commit), carrying:
+
+* `commit_sha`, `commit_index`, `commit_timestamp`
+* `production_code_diff` -- diff vs the previous kept commit
+* `diff_embedding`         -- Qwen3-Embedding of the diff (fp16, [2048])
+* `repo_state_embedding`   -- Qwen3-Embedding of the full repo state at this
+  commit (fp16, [2048])
+* `cross_repo_split`, `in_repo_split` -- the two split labels (see below)
+
+## Layout
+
+```
+commits/
+  cr_train.parquet    commits from the 400 train repos
+  cr_val.parquet      commits from held-out cr-val repos
+  cr_test.parquet     commits from held-out cr-test repos
+  ood_test.parquet    commits from the post-cutoff OOD repos
+```
+
+## Split semantics
+
+Two independent split axes:
+
+* `cross_repo_split ∈ {train, cr_val, cr_test}` -- which **repositories** the model has seen.
+* `in_repo_split ∈ {train, val, test}` -- chronological 80/10/10 split of each repo's **commits**.
+
+The four evaluation suites used in the paper map onto these axes as follows:
+
+| Paper suite | File | Selection |
+|---|---|---|
+| Train (loss) | `qna/cr_train.parquet`  | `in_repo_split == "train"` |
+| IR val       | `qna/cr_train.parquet`  | `in_repo_split == "val"`   |
+| IR test      | `qna/cr_train.parquet`  | `in_repo_split == "test"`  |
+| CR val       | `qna/cr_val.parquet`    | all rows                     |
+| CR test      | `qna/cr_test.parquet`   | all rows                     |
+
+All evaluation suites use the **full uncapped** assertion set. Only the in-repo train loss path is smart-capped (see `code2lora/code2lora-data-smartcap`).
+
+## Companion datasets
+
+* `code2lora/code2lora-data-smartcap`  smart-capped per-commit QnAs for training
+* `code2lora/code2lora-data-snapshots` static-snapshot variant
+* `code2lora/code2lora-data-ood`       OOD repos in the same schema
