SCoPE

Gives every token its camera ray as a second positional coordinate, making camera control part of the coordinate system instead of a bolted-on control module. Retrofits onto Wan2.2 for under 0.1% new parameters via a normalise-gate-inject step that preserves RoPE. Cuts rotation error 29% and improves FVD 43% at 14B scale. Code and weights are out.
