| # CodeLeWM Public Code-Edit Shard |
|
|
| This dataset repository hosts the public-safe CodeLeWM code-edit transition |
| shards used by the scaled May 2026 CodeLeWM training runs. It is a diagnostic |
| research artifact, not a benchmark leaderboard dataset and not a source of |
| broad model-quality claims. |
|
|
| ## What Is Hosted Here |
|
|
| | Run family | Path pattern | Role | |
| | --- | --- | --- | |
| | Scaled first public run | `runs/codelewm-scaled-20260520-9699b53/pack/**` | scaled code-edit transition pack | |
| | Action-use margin run | `runs/codelewm-action-use-20260520-6650183/pack/**` | action-use margin experiment data | |
| | Action-use retrieval run | `runs/codelewm-action-use-retrieval-20260520-7895d18/pack/**` | margin plus retrieval follow-up data | |
| | v0.2 action-swap/inverse-action run | `runs/codelewm-v0-2-action-swap-rerun-20260520-7c7cb0b/pack/**` | action-contrast remediation data | |
|
|
| Each pack includes manifest-backed metadata used by the CodeLeWM CLI. The |
| corresponding model checkpoints are in `abdelstark/codelewm-transition-model`, |
| and result reports are in `abdelstark/codelewm-runs`. |
|
|
| ## Dataset Information |
|
|
| The public shard represents Python code-edit transitions extracted for |
| CodeLeWM. Records are designed for transition-model training and evaluation: |
| before-state features, action/instruction views, after-state targets, split |
| metadata, and manifest checksums. The dataset is used by the package-native |
| training, retrieval, ablation, surprise, scorer-quality, and reranking |
| diagnostics. |
|
|
| Candidate code and source data are treated as untrusted inputs. CodeLeWM |
| parsing and scoring paths do not execute candidate patches by default. |
|
|
| ## Claim Boundary |
|
|
| The action-use experiments trained from these shards did not establish a |
| positive action-conditioned model-quality claim. In the documented runs, |
| no-action controls remained stronger on headline retrieval gates or later |
| claim gates failed. Use this repository for reproducible negative and |
| diagnostic evidence, not for claims of broad coding improvement. |
|
|
| ## Verification |
|
|
| Download one run pack and verify it locally: |
|
|
| ```bash |
| hf download abdelstark/codelewm-public-shard \ |
| --repo-type dataset \ |
| --include 'runs/codelewm-v0-2-action-swap-rerun-20260520-7c7cb0b/pack/**' \ |
| --local-dir .artifacts/hf-download/codelewm-public-shard |
| |
| uv run codelewm manifest verify \ |
| --manifest .artifacts/hf-download/codelewm-public-shard/runs/codelewm-v0-2-action-swap-rerun-20260520-7c7cb0b/pack/manifest.json \ |
| --json |
| |
| uv run codelewm secret-scan \ |
| .artifacts/hf-download/codelewm-public-shard/runs/codelewm-v0-2-action-swap-rerun-20260520-7c7cb0b/pack \ |
| --json |
| ``` |
|
|
| Expected result: manifest verification returns `ok=true` and the secret scan |
| returns `ok=true` with zero findings. |
