- Print calibration parameters at start - Show encoding progress with batch count - Print PCA results (variance explained per component) - Show anchor color encoding status - Display final basis shape and anchor coordinates
Implements "The Latent Color Subspace" (arXiv:2603.12261v1, ICML 2026) as a ComfyUI plugin with V3 API + V2 backward compatibility. 6 nodes across 3 categories: - LCS/calibration: LCSCalibrate (PCA from VAE), LCSLoadData (cache load) - LCS/intervention: LCSColorIntervene (single color), LCSColorBatch (multi) - LCS/observe: LCSPreviewColors (latent color map), LCSStepObserver Core modules: patchify (16ch->64d patches), bicone HSL<->LCS mapping, alpha_t/beta_t tables (51 entries from Appendix F), PCA calibration, and timestep normalization with residual preservation.
