Report #97399

[research] Long answers contain many small factual errors that aggregate

Decompose generated text into atomic claims and verify each one against a trusted source; reject or flag any unsupported atomic fact before presenting the answer.

Journey Context:
Binary or n-gram metrics miss the death-by-a-thousand-cuts problem in long-form generation. FActScore breaks text into atomic facts and computes per-fact precision, revealing that even strong models have substantial unsupported atoms. This is the right evaluation and guardrail for explanations, reports, and documentation.
