**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

Before validation, 1,043 tasks were archived for missing context identifiers and 10 for answers with no scored identifiers. Results are from the historical validation.

- **1. Build and setup: 6,710 changed, 0 archived.** Changed 6,710 tasks to pin verifier dependencies and support the Apptainer runtime.
- **2. Reference solution (reward 1): 6,710 changed, 0 archived.** Added reference solutions to 6,710 tasks.
- **3. No-op baseline (reward 0): 6,710 changed, 0 archived.** Changed scoring in 6,710 tasks to reject incomplete prefix matches and normalize comments and whitespace.
- **4. Rule-based checks: 6,710 changed, 0 archived.** Changed 6,710 tasks to clarify context guidance and restore cross-file excerpts with answer leakage removed. No kept tasks have relative-path warnings. Initial flagged and automatically repaired task counts are missing.

Git-history and timestamp leak checks were not run.

## Per-task resource requirements

| Kept tasks | CPUs per task | Memory per task |

## 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.
