Tier 1
Where Did It Come From
Fluency is not evidence.
Every generated answer needs a traceable source before it is cited. Open the record the system points to.
Tier 2
Retrieval Is Evidence
A grounded answer is only as good as what was retrieved.
RAG supplies documents at answer time. Check the retrieved source, not only the sentence written from it.
Tier 3
Verify the Agent
“Task complete” is a claim.
Agents act through tools inside permission boundaries. Human review stays final; content is data, not command.
