Complete paper tracing pixel-sample encoding from notepat recording through stample bitmap encoding to cross-platform painting-based sample storage. Connects Attali, Xenakis, Wishart, Navas to AC's practical implementation. Includes encoding analysis, architecture, design philosophy, and future work (collaborative sampling, generative samples, physical prints, federated samples via ATProto).
