Refuse answers sources do not support
Don't ship an answer unless its sources actually back it.
The technique
Agents often attach citations that do not actually support the claim. A grounding gate compares claim tokens to cited spans: accept when supported, refuse when citations are missing or unrelated, and regenerate when overlap is only partial. That blocks the common always-accept slip where a polished answer ships with decorative sources.
How it was tested
Offline structural sim (no live model): 10 grounding cases. Gate matched all 10 accept/refuse/regenerate decisions (4 accept, 4 refuse, 2 regenerate); caught 6 cases a naive always-accept path would have slipped.
