# ✦ 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).
