evidence-fetcher
================

``evidence-fetcher`` is an interactive evidence-search and relevance-feedback
experiment.

The current vertical slice fetches candidate web evidence from Brave Search,
normalizes the provider response, removes duplicate URLs, applies a lightweight
local relevance ranker, and exposes the results through a Python API, a
command-line interface, and a small Streamlit UI.

The feedback-aware reranking is based on a Rocchio-style relevance feedback
algorithm over TF-IDF vectors.

Because Interactive Information Retrieval can amplify the feedback you provide,
it should be used with care. The goal is to condense useful evidence from search
results, not to cherry-pick sources that only support a preferred conclusion.
