Resolves YES if by the end of 2022, traders who lost mana due to the misresolution of the linked market are able to recover their losses.

If any trader who wishes to recover their losses is able to, that counts as YES - it is not necessary for the recovery to be automatically applied to everyone. For example, what Yev and the community so kindly did on the accidentally misresolved market https://manifold.markets/RuthGraceWong/will-the-ftc-interfere-with-adobes would count as YES (but I wouldn't expect the same to happen here given the huge scale of losses.)
