# Multi-WAM World v6 migration bundle

This public repository is a reproducible transfer bundle for the current Multi-WAM RoboTwin2.0
World Model v6 stage. The 2026-08-05 update adds the complete modified v6 source, frozen
Qwen3-VL-2B runtime, the audited World step-80000 migration checkpoint, migration inputs, deployment
evidence, and an agent Skill. Unchanged, SHA-identical archives from the previous release are reused:
the packed `mira` conda environment, codec step-125000, LingBot/Wan runtime assets, and the complete
27,500-episode latent/text cache.

The raw RoboTwin2.0 dataset is intentionally **not included**. Download or mount the 100 ALOHA ZIP
files separately at `datasets/RoboTwin2.0`; World v6 needs their original three-view RGB frames when
building Qwen anchors.

## Current restore set

| Archive | Restores | Status |
|---|---|---|
| `source-code-world-v6-20260805.tar.zst` | current `mira/`, `lingbot-vision/`, v6 plans | new |
| `mira-conda-env.tar.zst` | relocatable Python 3.12 / Torch 2.8 CUDA 12.8 environment | reused |
| `runtime-models.tar.zst` | LingBot-Vision Large and Wan UMT5 assets | reused |
| `qwen3-vl-2b-instruct.tar.zst` | pinned frozen Qwen3-VL-2B current encoder | new |
| `codec-checkpoint-step125000.tar.zst` | codec weights plus optimizer/training state | reused |
| `world-checkpoint-step80000.tar.zst` | complete 32-shard audited v5 World migration source | new |
| `world-derived-cache.tar.zst` | complete latent/text cache and generated metadata | reused |
| `world-v6-migration-inputs.tar.zst` | EMA selection, state encoder, smoke reports/videos | new |

Historical source, World-50k, and individually uploaded World-80k objects remain in repository
history for compatibility, but the current restore script does not download or extract them.

All current payloads are covered by `SHA256SUMS`. Exact source/archive sizes, hashes, model contracts,
and reused/new status are recorded in `PACKAGE_MANIFEST.json`. No credential is included.

## Direct selective download

Install a recent Hugging Face CLI, clear every proxy, and download only the current restore set:

```bash
unset http_proxy https_proxy all_proxy ftp_proxy HTTP_PROXY HTTPS_PROXY ALL_PROXY FTP_PROXY
export NO_PROXY='*' no_proxy='*' HF_XET_HIGH_PERFORMANCE=1

hf download Orangerl/multi-wam \
  --include README.md PACKAGE_MANIFEST.json SHA256SUMS 'skills/**' \
    archives/source-code-world-v6-20260805.tar.zst \
    archives/mira-conda-env.tar.zst \
    archives/runtime-models.tar.zst \
    archives/qwen3-vl-2b-instruct.tar.zst \
    archives/codec-checkpoint-step125000.tar.zst \
    archives/world-checkpoint-step80000.tar.zst \
    archives/world-derived-cache.tar.zst \
    archives/world-v6-migration-inputs.tar.zst \
  --local-dir multi-wam-hf
```

Then ask an agent to use `skills/multi-wam-migrate/SKILL.md`. The deterministic restore entry point
is:

```bash
bash skills/multi-wam-migrate/scripts/restore_bundle.sh \
  "$PWD" /path/to/Mutil_WAM /path/to/conda/envs/mira
```

After downloading/mounting the ALOHA data and creating a destination-local SwanLab token, run
`verify_install.sh` and `start_world_v6_smoke.sh`. The smoke launcher uses only physical GPUs 6 and
7. Formal World v6 remains an explicitly guarded eight-GPU pipeline.

MIRA and LingBot-Vision retain their upstream Apache-2.0 notices. Bundled third-party model assets,
checkpoints, and conda packages retain their respective licenses, so this aggregate repository uses
the mixed/other label rather than relicensing its contents.
