[tantek]right, this to me is sounds like a suggestion to improve indiewebifyme's h-entry validator to catch this error in particular and warn the publisher with a very specific error message
[tantek]re: "I don't know how to catch it" — at least for indiewebifyme, look for a u-url in the h-entry that is a prefix of the actual (submitted) URL, that should not be possible
[tantek]from your issue: "https://www.oh.mg/2024/02/farscape-and-capitalism/ both have incorrect u-url of https://www.oh.mg/2024/02/" (note that the latter URL is a string prefix of the former URL)
