Today the Palace released a photo of Kate Middleton which was killed shortly after by AP and Reuters because of evidence that it was doctored.

Resolves YES if undoctored, contemporary, evidence of Kate Middleton sitting and talking, or standing, or walking unassisted, and looking recovered (smiling, normal skin color, taking normal strides) is available before July 1, 2024. This could be an account from a very trustworthy individual (ie non-Palace affiliated journalist), a convincing enough photo or video. My threshold will be roughly "beyond a reasonable doubt.” I will not count evidence from the Sun or Daily Mail

Because resolution is subjective I'm not going to bet.
