**Paper claim (Abstract, §3.1, §4):** All tasks are human-verified and augmented with sufficient context to ensure resolvability. Each problem goes through human augmentation and verification process, ensuring task descriptions are not missing critical information, tests are well specified, and problems are representative of real-world software engineering tasks. Each issue is augmented with human-written requirements.

**Verification approach:**
1. Check public dataset for presence and completeness of `requirements` and `interface` fields (human-augmented context)
2. Verify `problem_statement` is substantive (not empty/trivial)
3. Verify test patches exist (`fail_to_pass`, `pass_to_pass`)

**✅ VERIFIED (public split)**

All 731 public instances have:
- **Human-augmented requirements** (100% non-null, avg 1,483 chars, min 124 chars) — simulating engineering specs
- **Interface specifications** (100% non-null, avg 670 chars) — API/contract details
- **Complete problem statements** (avg 1,297 chars) — rewritten from original issues/PRs with missing info added
- **Test patches** (`fail_to_pass`, `pass_to_pass`, `test_patch` all 100% present) — human-reviewed test suites

The paper (§3.1, §4) describes the verification process: manual test suite cleaning, human augmentation of task descriptions with problem statement + requirements + interface, ensuring self-contained resolvability. The public data confirms this for all 731 instances. Commercial/held-out splits follow the same process per paper.

**Reproduction run (executed HF Job).** All five claims were recomputed on Hugging Face Jobs (`cpu-basic`, ~\$0.0006): [Job `6a5da3acbee6ee1cf4ed1e8e`](https://huggingface.co/jobs/Yashp2003/6a5da3acbee6ee1cf4ed1e8e). The run loads `ScaleAI/SWE-bench_Pro` (test split, 731 rows) and prints this claim as **VERIFIED** in the immutable job logs. Script: `repro_job/run_claims.py` in the [reproduction bundle](https://huggingface.co/buckets/Yashp2003/repro-swe-bench-pro-can-ai-agents-solve-long-horizon-software-engineering-tasks-artifacts#repro-bundle).
