# Fuzzy LangChain — Hugging Face API

Minimal deployable API for the Fuzzy LangChain RAG runtime. This package intentionally contains **only the serving surface and the minimum runtime needed by it**. Benchmarks, experiments, tests, and research documentation belong in the GitHub RAG repository.

Endpoints: `GET /health`, `POST /ingest`, `POST /query`.

The query path runs through the actual LangChain `BaseRetriever` implementation, fuzzy evidence assessment, optional retrieval expansion, grounded answer generation, citation return, and abstention under insufficient or ambiguous evidence.

See `API_SPEC.md` for request/response examples.
