Answer Audit — skeptical review of a grounded answer

A RAG answer that is fully citation-grounded can still be materially wrong. Every claim can trace to a real passage while the values inside those claims are silently corrupted in transit. This skill exists because a confident, well-structured, 100%-grounded answer is the hardest kind to catch — the citations create trust the content has not earned.

Default posture: the answer is guilty until proven innocent. Do not grade it on how it reads. Grade it on whether each atom survives a character-level diff against its source.

The rule that matters

Grounded ≠ accurate. Citation presence is not citation support.

Most RAG guardrails ("no sources → no answer", "cite every claim") only prove a passage was retrieved. They do not prove the passage says what the answer says it says. Audit the gap.
