Silent Failure #3: The Duplicate Check Searches the Issue Number Nobody Wrote

The issue-number query answered a narrower question than the one you needed, and the file-path and timeline searches give useful independent signals. The 200-PR limit is another boundary worth exposing in the results: in a busy repository an empty recent window still says nothing about older open work. A dedupe check could show its time window and pagination status alongside candidate matches rather than presenting an unqualified “none found.”

This is a useful rule: an empty search result is not proof there is no duplicate, only that nobody used your words. I now check the file's recent PRs and the issue timeline first, before searching by number. The file-path filter is the part I will steal for my own checks.
