Challenge

A large, heterogeneous archive made it slow and error-prone to find authoritative answers, with no traceability back to the source document.

Approach

We built hybrid retrieval (vector + keyword) with cross-encoder re-ranking over the archive, citation-backed generation, and an automated evaluation harness to keep answers grounded and auditable.

Impact

Authoritative, cited answers retrieved faster, each one traceable to its source. [[Replace with an approved metric.]]
