# MA048181

MA048181 is a public reproducibility bundle containing the raw PanTS train/test data package, the derived Wan2.2 training cache, code snapshots, logs, and final saved checkpoints for the UCSF run `pants_b16_9k_20260519_215532`.

## Contents

### `raw_pants_train_test/`

Original raw PanTS data package.

- Raw source path on UCSF: `/scratch/user/yuhwang/dataset/PanTS`
- Packaged size: about 337G
- Includes `ImageTr`, `ImageTe`, `LabelTr`, `LabelTe`, `metadata.xlsx`, and PanTS repo README/license/download scripts.
- Restore instructions: `raw_pants_train_test/raw/RESTORE.txt`

Observed raw data summary:

- `ImageTr`: 9000 cases, 9000 files, about 296G
- `ImageTe`: 901 cases, 901 files, about 27G
- `LabelTr`: 9000 case dirs, 260999 files, about 45G
- `LabelTe`: 901 case dirs, 26129 files, about 4.0G

### `model_cache_code_step8000/`

Derived training cache, final checkpoint, and code snapshot package.

- Derived cache source path: `/scratch/user/yuhwang/dataset/pants-captions-ldm/cache/wan22_pants_v2_softwin`
- Packaged size: about 161G
- Main train manifest: `captions_embedded/source_train.jsonl`
- Manifest row count: 53,784
- Contains VAE latent cache, text embedding cache, captions, embedded-caption manifests, code snapshot, logs, and checkpoints.

Final complete checkpoints:

- non-EMA: `model_cache_code_step8000/checkpoints/checkpoint-8000/transformer/`
- EMA: `model_cache_code_step8000/checkpoints/ema_checkpoint-8000/`
- distributed resume state: `model_cache_code_step8000/checkpoints/checkpoint-8000/distributed_checkpoint/`

Important status note: training targeted 9000 steps, but the 2-day Slurm allocation ended after step 8016. The last complete saved checkpoint pair is step 8000. Logs showed no traceback, OOM, or NaN.

## Data Layers

This repository intentionally keeps three layers together but separated by directory:

1. Raw PanTS train/test data: `raw_pants_train_test/`
2. Derived VAE latent cache: `model_cache_code_step8000/cache/wan22_pants_v2_softwin.tar.zst.part-*`
3. Derived text embedding cache: inside the same cache archive, under `text_embeddings/`

## Restore

Restore raw PanTS:

```bash
cd raw_pants_train_test/raw
cat PanTS.tar.zst.part-* > PanTS.tar.zst
tar --use-compress-program zstd -xf PanTS.tar.zst
```

Restore derived cache:

```bash
cd model_cache_code_step8000/cache
cat wan22_pants_v2_softwin.tar.zst.part-* > wan22_pants_v2_softwin.tar.zst
tar --use-compress-program zstd -xf wan22_pants_v2_softwin.tar.zst
```

Restore code snapshot:

```bash
mkdir -p code_restore
cd code_restore
tar --use-compress-program zstd -xf ../model_cache_code_step8000/code/twoframe_fastvideo_code_snapshot.tar.zst
```

## Integrity

Each subpackage has its own `SHA256SUMS.txt` and `PACKAGE_COMPLETE` marker.

```bash
cd raw_pants_train_test && sha256sum -c SHA256SUMS.txt
cd ../model_cache_code_step8000 && sha256sum -c SHA256SUMS.txt
```

## Notes

The base Wan2.2 model binaries are not duplicated here. The fine-tuned transformer checkpoints and the base-model symlink map are included in `model_cache_code_step8000/metadata/base_model_symlinks.txt`.
