# CodeLeWM Run Artifacts

This dataset repository is the public artifact registry for CodeLeWM training,
evaluation, demo, and publication runs. It is organized as manifest-backed run
trees rather than as a conventional train/test dataset.

## What Is Hosted Here

| Artifact family | Example path | Role |
| --- | --- | --- |
| v0.2 and earlier code-edit runs | `runs/codelewm-action-use-retrieval-20260520-7895d18/**` | negative action-use and retrieval evidence |
| v0.7/v0.8 execution runs | `codelewm-v0-8-short-execution-20260605-1b737e4-seed-42/**` | execution-transition diagnostics |
| v0.9 execution runs | `codelewm-v0-9-short-execution-20260606-69f798a-seed-{42,1729}/**` | final execution-training and reranking artifacts |
| Visual/demo bundles | `visual-observability/**` and related run paths | UI and harness diagnostics |

Artifacts include manifests, configs, reports, checkpoint metadata, benchmark
outputs, and selected checkpoint files. The primary current dataset is
`abdelstark/codelewm-execution-pack`; historical code-edit shards are in
`abdelstark/codelewm-public-shard`.

## Dataset And Model Context

- Current execution dataset: `abdelstark/codelewm-execution-pack@v0.9.0-rc1`,
  2,188 tokenized `(code, input, output)` records with deterministic sandbox
  provenance.
- Historical code-edit dataset: `abdelstark/codelewm-public-shard`, used by
  the scaled/action-use experiments.
- Historical transition-model checkpoints:
  `abdelstark/codelewm-transition-model`.
- v0.9 execution checkpoints and run reports are stored directly in this
  repository under their run ids.

## Claim Boundary

CodeLeWM is claim-gated. These artifacts support reproducibility, inspection,
and diagnostic comparisons. They do not support a broad claim that CodeLeWM
generally improves coding. The final public evidence supports negative
action-use conclusions plus a narrow HumanEval WS-D reranking slice; the
aggregate downstream claim remains closed.

## Verification

Download a v0.9 run tree and verify it locally:

```bash
hf download abdelstark/codelewm-runs \
  --repo-type dataset \
  --include 'codelewm-v0-9-short-execution-20260606-69f798a-seed-42/**' \
  --local-dir .artifacts/hf-download/codelewm-runs

uv run codelewm manifest verify \
  --manifest .artifacts/hf-download/codelewm-runs/codelewm-v0-9-short-execution-20260606-69f798a-seed-42/manifest.json \
  --parent-manifest .artifacts/v0_9/hf-pack-download/artifact_manifest.json \
  --json

uv run codelewm secret-scan \
  .artifacts/hf-download/codelewm-runs/codelewm-v0-9-short-execution-20260606-69f798a-seed-42 \
  --json
```

Expected result: manifest verification returns `ok=true` and the secret scan
returns `ok=true` with zero findings. The parent-manifest path should point to
a local download of `abdelstark/codelewm-execution-pack@v0.9.0-rc1`.
