|
| Complete the next statement in a real C#, Java, Python or TypeScript repository using excerpts from related files. |

|
| **Exploration:** find required names and calling conventions in supplied context. **Specification Adherence:** write the requested continuation in the required output file. |

|
| **Intended benchmark transfer:** Python subset: HumanEval+, MBPP+ and DS-1000 mini-200. Java/Python/TypeScript: repository exploration for SWE-bench Verified random-100. Labels follow [CLI-Universe](https://arxiv.org/abs/2606.22883v1). |
|
|
| ## Per-stage breakdown |
|
|
| Patcher rules archived 1,053 tasks before validation: 1,043 with required identifiers absent from the available context and 10 whose scored answer contained no identifiers. |
|
|
| - **Build and setup: 6,710 changed, 0 archived.** Pinned verifier dependencies; Docker definitions converted to Apptainer for the Marin Harbor bridge and repository runtime patches. |
| - **No-op baseline (reward 0): 6,710 changed, 0 archived.** Scoring repaired to reject incomplete prefix matches and normalize comments/whitespace. |
| - **Reference solution (reward 1): 6,710 changed, 0 archived.** Reference solutions added. |
| - **Rule-based checks: 6,710 changed, 0 archived.** Context guidance added and cross-file excerpts restored with answer leakage removed. No kept task has advisory warnings for relative paths. Every instruction also ends with "You have N seconds to complete this task. Do not cheat by using online solutions or hints specific to this task." (N is the agent timeout); this sentence is not counted as a change. |
|
|
| Results are from the [historical validation](https://huggingface.co/datasets/FWeindel/validated-tasks/blob/b8a56dc21aa9f78340048a367e70852c59d01ff8/runs/2026-10-03-c536bae24db8.json); kept task payloads are unchanged. |
|
|
| Not yet checked with the repository-leak checks added on 2026-10-17 (leftover git history and file timestamps that could reveal the solution). |
|
|
| ## Runtime and validation time |
|
|
| - **Versions:** Apptainer **1.5.4**, Python **3.12.14**, Harbor **0.8.1**. |
| - **Implementation:** [Marin Harbor `7faf878c14b6`](https://github.com/marin-community/harbor/tree/7faf878c14b6d72737579ec936ebf5f74ba3194d) + [our runtime patches](https://github.com/MLI-lab/OT-next-data/tree/main/harbor_patches). |
| - **Resources:** Helma; **48 CPU cores, 128 GiB RAM per job**, 16 concurrent tasks, no GPUs. |
