Existing players
- Manual corpus curation · Doesn't scale
- Ragas · Evaluates answers, not source freshness
- Perplexity-style web RAG · Better recency, still misses retractions
What they are missing
Source-freshness scoring: every retrieved chunk gets a recency, supersession, and retraction score. Citations get a colour-coded confidence band. Refused if the source has been retracted or formally deprecated.
