This site publishes itself every morning at 08:00 KST, unattended. Building that pipeline turns up things that are wrong. These are the ones worth writing down — what broke, what the numbers actually were, and what the fix was, with the code. Not news summaries: a record of this site itself.

One outlet wrote 8 of 9 articles. The cap that should have stopped it stepped aside on purpose.
A three-article cap keeps one outlet from owning the edition. It lifts entirely rather than leave a slot empty. That happened four times in 28 editions, and only twice because the news was actually thin. One was a configuration mistake of mine. One I still cannot explain.

Zero Korean articles on 15 of 19 days. The other 4 were worse.
The keyword extractor behind our cross-source bonus only matches capitalized ASCII, so Korean headlines cap out at 3.0 against a weekday cutoff above 5. Yet they do run on Sundays and Mondays. Not on merit, but because the English feeds have gone quiet.
