Weights + atlas for the AlphaMotion engine (https://github.com/Lloyd-lei/Greenwich):
| artifact | what |
|---|---|

Qwen3 joint-name embedding cache (299 names) |
Install the engine, then alphamotion download pulls the v0.1 stack plus
megatron; alphamotion download --models bumblebee,megatron,prime pulls the
whole v2 ladder. The v2 codecs need the embodiments_v2 descriptor set that
ships inside the package (not here). Audit numbers: docs/BENCHMARK.md.
Benchmark: see docs/BENCHMARK.md in the code repo; reproduce with
alphamotion eval.
