This paper studies phase memory and affine-source decoherence in torsionful twistor transport across Mixmaster/Taub bounce dynamics. It isolates an exactly solvable one-wall sector, proves a winding classification for principal Weyl-source channels, and checks a four-bounce, five-plateau model of cumulative memory suppression. The result links anisotropic Weyl-source transport with BKL/Mixmaster dynamics through explicit spinor-channel phase accumulation.
