Agree what makes a subject the intended subject
Start with a small catalogue containing similar names, several categories and topics that fit more than one tag. Define the information a visitor uses to distinguish subjects before leaving a rating. A category label alone may not provide enough context. Decide which fields belong on discovery cards and which details belong on the destination page. Keep the topic reference consistent across the catalogue, review page and signed-in activity so browsing through a different path still reaches the same subject.
