The listening VAE decoder of m-a-p/YuE2-Vae (M-A-P), converted for MLX. It is used by mlx-yue2-swift, the Swift-MLX port of YuE2-3B, together with mlx-community/YuE2-3B-bf16 (usage on that card). It is an Oobleck decoder: 64-dim latents at 25 Hz → 48 kHz stereo, fp32, decoded in exact tiles.

Parity: the folded tensors equal upstream's own remove_weight_norm output (max |Δ| 0). The Swift decode matches the fp32 PyTorch oracle to relL2 ≤ 4.6e-6, and the tiled decode equals the full decode within 2.7e-6.
