Needle available on Android possibility

Hi,

I am looking to load Needle through cactus-react-native on Android also iOS in the future.

Current state as I understand it:
- Needle on HF is published as JAX/Flax (needle.pkl, ~53MB)
- cactus-react-native's model registry doesn't include Needle yet
- v1 moved from GGUF to .cact, so the obvious 'just load a GGUF' path doesn't apply here.

Questions:
1. Do you have an item on the roadmap for Needle in the RN SDK model list?
2. Is the .cact format / conversion pipeline documented for external use? Willing to give porting if there's a starting point.
3. Any recommended intermediate path (ONNX export, server-side until ready, etc.)?

Context: Love the idea of adding a light tool calling LLM to mobile apps

Start with the cactus-react-native model registry and investigate the documented .cact conversion pipeline, if one exists. Check whether Needle's JAX/Flax artifact can be supported on Android and iOS; done requires a confirmed roadmap or a documented conversion and integration path.
