A deployed evidence navigator for oncology reviewers, with source-linked answers, visible uncertainty and explicit quality boundaries.

Problem
Reviewers had to synthesise fast-moving NSCLC evidence across scattered sources under clinical review pressure.
System
A bounded navigator combined controlled sources, semantic retrieval, deterministic guardrails and LLM-assisted synthesis.
Evaluation
- Retrieval correctness and citation faithfulness.
- Answer faithfulness and time-to-evidence.
- Reviewer agreement and error analysis.
Boundary
Every answer had to remain traceable to evidence and review. Unverifiable citations, hallucinations or low reviewer trust would stop or redesign the system.
Before
Reviewers manually stitched together fast-moving oncology evidence from scattered sources, with limited time to inspect how a summary was produced.
After
Reviewers can navigate source-linked evidence, visible uncertainty and a traceable review trail. Clinical judgment stays with the reviewer.
