The Lyra Technique II: SVD Denoising and Directional Projection.
Two new measurement channels extend KV-cache geometry to emotion and persona detection
W_K directional projection classifies 30 emotions at 12.3x chance (AUROC 0.992 valence) and injection into neutral text confirms model state, not text encoding. SVD denoising reveals hidden signal: persona intensity jumps from AUROC 0.611-0.751 to 0.899-0.992. Dominant singular values carry scale; residual values carry discriminative structure. Denoising is a calibration tool, not a universal amplifier.
