Why do my RAG search results look correct but the answer is still wrong?
Retrieval shows the right chunks in the trace. The LLM still produces a hallucinated, slightly wrong, citation-broken answer. Debugging is guesswork.
Who has it: Engineers running customer-facing RAG (support bots, internal search, doc Q&A).
Evidence
Engineers describe retrieval returning chunks that contain the exact answer while the model still says it does not know or invents a plausible wrong one, eating senior engineering time.

Existing players
- Ragas · Evals but mostly offline
- LangSmith · Traces, weak on retrieval diagnostics
- Arize Phoenix · Closer; setup heavy
What they are missing
RAG-specific drift detection: side-by-side of "retrieved evidence" vs "model answer", auto-flag when citations don't appear in the answer or vice versa, and a regression test set seeded from real failures.
