Fix Documentation Errors

Several examples visibly note errors in migration, running, or output data. It would be good to address these on a case-by-case basis.

Start with the linked example documentation pages, checking each migration, run, and output note for the reported errors. Work through the checklist case by case and verify each corrected example and its documented output; done means the visible errors in all listed pages have been addressed.
