A university admissions agent answers from two current sources that disagree. A campus blog says a program is open to first-year students, and the official catalog says it is not. Which grounding change should the architect make?
Select an answer to reveal the explanation.
Short Explanation
Two notices on the same door do not carry the same weight when one of them is the catalog. You treat the official catalog as the authoritative source and take the contradictory blog out of grounding. A refresh leaves the conflict in place when both documents are already current.
Full Explanation
Grounding accuracy asks which source is authoritative when two current documents disagree. The catalog is the university's rule for who may enter a program, and the blog is a current page that says the opposite, so the catalog stays and the blog leaves the grounding set. If both pages remain, the agent can quote whichever passage sits closer to the question. Refreshing the blog and the catalog on a schedule treats the defect as staleness, but both sources are already current, so a refresh publishes the same contradiction again. A longer system instruction that tells the agent to sound sure does not choose a source, and a prompt does not outrank the text that was retrieved. Fine-tuning a custom model on the blog teaches the unofficial post as the rule and drops the catalog the admissions office maintains. Exam caveat: a document can be current and still be the wrong authority when a system of record says otherwise. Operational check: ask the eligibility question after the blog is removed and confirm the reply follows the catalog and does not repeat the blog's claim.
