Well, the preprint announcing the discovery describes its orbit as extending to "the inner Oort cloud" even though aphelion is 1630 au. https://arxiv.org/abs/2505.15806

> and probably out at several 1000 AU at maximum. The preprint announcing the discovery lists the semi-major axis as 838 au, so the major axis is 1676 au and aphelion is about 1630 au. https://arxiv.org/abs/2505.15806
