# Statement Portfolio

Redrafted problem statements for 2,094 feature-implementation instances from
[`nebius/SWE-rebench-V2`](https://huggingface.co/datasets/nebius/SWE-rebench-V2),
as used in the statement-portfolio experiments of our paper. Each instance has three
redrafts of the same required change:

| `variant` | Style |
|---|---|
| `narrative` | Explains the requested change and its intended behavior in prose |
| `acceptance` | Leads with the criteria that a completed implementation must meet |
| `scope` | States what the change should include and exclude |

Redrafts were written by a multi-agent pipeline (two drafters, cross-critique,
arbiter) that reads the public pull-request record (linked issues, review discussion,
PR description, commit messages). The reference patch and hidden tests were never shown
to the drafting models.

## Fields

| Field | Description |
|---|---|
| `instance_id` | SWE-rebench-V2 instance id (join key) |
| `repo`, `pr_number` | Source repository and pull request |
| `language` | Repository language |
| `base_commit` | Repository snapshot the task starts from |
| `variant` | `narrative`, `acceptance`, or `scope` |
| `problem_statement` | The redrafted statement, exactly as given to the agent |
| `generation` | How the statement was produced |

6,282 rows (2,094 instances × 3 variants).

## Reconstructing executable tasks

This release contains statements only. Repository snapshot, reference patch, test patch,
`FAIL_TO_PASS`/`PASS_TO_PASS` tests, and environment configuration come from
SWE-rebench-V2 at revision `475dd5e8703bb5fb22dd3c60b5d038b019eba1e0`; join on
`instance_id`.
