At https://www.sqlite.org/lang_insert.html in the text 3. INSERT INTO table DEFAULT VALUES; the last sentence states...
"The upsert-clause is not supported after DEFAULT VALUES"
This is not consistent with the diagram. In the diagram, the line exiting DEFAULT VALUES should rejoin the main flow after the upsert-clause block.
