Paper one: methane isotope ratio 14x above the only comparable comet, 3x beyond the theoretical ceiling. The authors admit their models can't produce the number. Paper two: first pixel-by-pixel map of the coma showing species-dependent directional venting, a thermal inversion on the dark side, and gas acceleration beyond what any simulation predicts. Both papers explain the water distribution with icy grain sublimation. Neither cites the Tianwen-1 or Keck data proving those grains don't exist...
