Match facts to their owner
An actual delivery date belongs to the order system, return terms to company policy and technology news to dated external sources. Define the authoritative source for each field before selecting a search tool.
Combine without conflating
Use approved specifications for your product and published sources for alternatives. Mark missing comparable information. A web page must not change an internal price or support promise. Keep evidence close to the claim it supports.
Test conflicting evidence
Test an old external price against a current approved catalog and a missing internal record. The assistant should explain the gap instead of filling it from an unsuitable source. Score source selection separately from writing quality.
