What changed
MisKnow-Agent created 5,933 controlled misleading research instances. Agents sometimes carried false conclusions into final reports even when search-enabled verifiers identified the falsehood in a direct check.
Why it matters
A verifier somewhere in the pipeline does not make the whole research workflow trustworthy. Failures can occur during evidence selection, context mixing and synthesis.
What to do
Attach provenance metadata to every context object, verify before synthesis and again after drafting, and retain exact supporting passages.
Caveat
The result comes from a new controlled stress-test preprint, not an estimate of production incidence.
