🧠 Retrieval Trace Auditor

Retrieval Trace Auditor inspects the evidence path behind a RAG or knowledge-agent answer. Supply structured JSONL cases with stable retrieved evidence IDs, expected evidence when known, citations, answer claims, declared support IDs, query class, and route. The included deterministic local helper detects expected evidence that was not retrieved, citations or claim support that never appeared in context, claims with no declared support, stale selected evidence, unused retrieved context, and temporal or relational questions routed through vector-only retrieval. It returns severity-ranked findings, per-case dispositions, a release gate, and a review memo. It deliberately does not claim to judge semantic entailment or factual correctness.
