| # ✦ AstraNexus | |
| Unsupervised email organizer. A **fine-tuned** multimodal encoder (MiniLM text + | |
| SigLIP vision) embeds each email, HDBSCAN clusters them into **constellations**, | |
| cross-account threads show as **wormholes**. Custom FastAPI frontend (landing at | |
| `/`, Gradio app mounted at `/app`); LangGraph orchestration emits `trace.json`; | |
| runs fully local (no cloud LLM APIs on the default path). | |
| Fine-tuned encoder: [DriptoBhattacharyya/astranexus-mm-encoder](https://huggingface.co/DriptoBhattacharyya/astranexus-mm-encoder). | |
