Report #97397

[research] The model invents facts by misreading search results or API responses

Pass tool outputs in a stable schema and force the model to quote exact fields or snippets before synthesizing; validate the final claim against the raw tool output, not against the model's paraphrase.

Journey Context:
Tool access does not eliminate hallucination; models can misread JSON, conflate fields, or overinterpret search snippets. ReAct-style reasoning traces help, but the real guardrail is exact-quote grounding: the model must point to the specific value or sentence it is using, and a post-processor checks that the claim is entailed by that raw output.
