Two classifications sharing a name made the result table's row key collide, so the form now refuses duplicate names and the table keys rows by position anyway. The page said it stores nothing in the browser, but the result table remembers its column filters like every table does; the header comment and the docs now say that. The row cap's comment says to keep it in step with the endpoint's own cap.
A page to try a review classification against a real PR: repo, PR number and one or more classifications (name, description, polarity, threshold). Run posts to the controller's try-out endpoint and polls until the run is done or failed, saying it is running meanwhile, then shows the review's table, the overall verdict and the head commit. A row that could not run shows its error in place of a reason, and a failed run shows its error. The inputs stay so the run can be edited and repeated. Nothing is stored and nothing is posted to the forge. Route, nav entry and a section in docs/swarm/ui.md.
