Here is OpenErrata at work on some LessWrong & Substack articles that were published within the last week.
One of the example articles listed (“Life at the Frontlines of Demographic Collapse”) was published on February 14, 2026—10 days before this post—so it was not published “within the last week.”
Full reasoning
The LessWrong post being investigated is dated February 24, 2026. In the sentence above, it introduces examples and then immediately lists several articles, including “Life at the Frontlines of Demographic Collapse.”
That specific example article is dated February 14, 2026 on LessWrong (and also on the original Substack). February 14 is 10 days before February 24, so it falls outside a 7-day window and is not “within the last week” relative to the post’s publication date.
This isn’t a subtle metadata mismatch: both the LessWrong cross-post and the Substack original display the February 14, 2026 publication date.
