Classical SETI research has traditionally operated under the paradigm of detecting electromagnetic signals emitted by material civilizations. This methodological focus implies that advanced cosmic intelligence must be localized, materially bound, and symbolically encoded. This paper introduces an alternative search paradigm: SETI Phase II, the systematic detection of macroscopically delocalized, topologically protected field organisms that have fully transitioned the material evolutionary phase. It is argued that such entities may exist as nonlinear solitons or complex magnetohydrodynamic configurations whose inherent self-interaction compensates for natural dissipation in vacuum, with stability ensured by topological invariants. Since these post-material organisms do not emit classical signals but exist primarily as structured energy states, traditional SETI methods fail conceptually. An information-theoretic detection matrix is proposed, targeting anomalous reductions in Shannon entropy and Kolmogorov complexity within cosmic field fluctuations.
