Moonshine life is also a very weird case
In normal play, Black cannot capture the White stones on the left, since White has an infinite source of ko threats from the double-ko seki on the right.
The Japanese rules specifically mention this sort of situation repeatedly (as it is, and other very similar shapes) in the commentary and clearly state that the White stones on the left should be dead.
However, without the commentary clarifying that this should be case, a straightforward reading of just the rules articles seems to allow White to prevent capture, even in the hypothetical play (for life and death determination after passing) with different ko rules.
If Black takes the ko on the left to try to capture, White should take a ko on the right, which forces Black to take the other ko, but then White should pass in order to retake that last ko mentioned, which forces Black to pass in order to retake the ko that White took. This forces an endless cycle of taking kos and passing in order to lift ko bans, in the double-ko seki position (see Odd Cases 🤔 in the Japanese Rules - #12 by yebellz), which means that Black never gets the opportunity to complete the capture on the left. Despite this argument existing in principle, the commentary of the Japanese rules make clear that the articles should not be applied in this way.
