A source link is the beginning of answer provenance, not proof that every statement is supported. An impressive reference list can conceal a claim that does not follow from the passage, version, or permission context. Connect important claims to the exact supporting text and retain the document version that was used. Ask someone outside the build team to reconstruct an answer from its trace. Review unsupported jumps expressed as therefore, always, or must. Protect the trace as business data, because excerpts may themselves be confidential. Useful provenance explains the answer without granting broader access to its evidence. Original article explainer. AI-assisted conceptual illustration and neural narration; original synthesized music. Not a human recording or customer result.
