INLP Projection Transmission: Domain-Specific Activation Transfer at the Natural Language Boundary

Text baseline already achieves 95% domain classification accuracy. INLP injection provides marginal +1.9%, outperforming full activation injection (+1.3%). The 36-dimensional INLP projection outperforms the full 3584-dimensional activation injection. Sender and receiver encode domain in nearly orthogonal directions (cosine 0.27). Procrustes alignment fails (residual > 1).
