## Claim 2 — Three-way partition (11 / 12 / 18)

**Claim (verbatim):** "SWE-Bench Pro is split into a public set of 11 openly accessible repositories, a held-out set of 12 repositories not publicly accessible, and a commercial set of 18 proprietary repositories obtained via partnership agreements with startups."

**Verdict:** Consistent — the public portion (11 repos, 731 instances) is directly verifiable; the held-out (12) and commercial (18) splits are described as non-public by design and align with the paper's stated 41-repo total and contamination-resistance goal.

### What we verified
From the public release **[ScaleAI/SWE-bench_Pro](https://huggingface.co/datasets/ScaleAI/SWE-bench_Pro)**, every one of the 731 instances belongs to exactly one of **11 distinct `repo` values** (see Claim 1 table). The dataset README explicitly states `repo`: "Repository identifier - one of 11 repository classes", confirming the public set is exactly 11 repositories.

### Reconciliation with the paper
| Split | Repos (paper) | Status | Verifiable here? |
|---|---|---|---|
| Public | 11 | Openly accessible | Yes — 11 repos, 731 instances counted |
| Held-out | 12 | Not publicly accessible | No (by design) |
| Commercial | 18 | Proprietary, partnership agreements | No (by design) |
| **Total** | **41** | | 11 + 12 + 18 = 41 ✓ |

The arithmetic 11 + 12 + 18 = 41 matches the 41-repo total in Claim 1, and the paper notes "Problems in the held-out and the commercial set are not publicly accessible, but we release results on the commercial set." This is exactly why only the 11 public repos are observable in the open dataset — not a contradiction.
