Programmatically validate new content against old content

[ctrueden]

I had an idea: we could strip all non-alphameric characters from the old mw pages, and then diff against the new md pages... and then diffs that are sufficiently large blocks of minus signs are indicative of content that disappeared during the migration. It would be worth a shot to do this, just to make sure we haven't inadvertently deleted swaths of content. In particular, I know that some asides (previously "Sidebox" template, now "aside" include) didn't get migrated over, and there may be other things as well.

I tried various things, wrote a script to tokenize both .md and .mw files, and compared them across the site in various ways, but could not find any instances of content that was lost in translation. I know there were some, but maybe they've all been fixed now? Or maybe I didn't look hard enough. But regardless, if there are any such instances, they appear to be few and far between. So I'm going to close this as resolved.
