By writing the unchecked outputs before checking them, they will be written to a store path, which appears in the log, and which sticks around even if the build fails. Eventually it is GCed, but until then, you can open the file. If you run it in a terminal+editor combination like VSCode, the failure location is just one Ctrl+click away.
