Geometric–Temporal Derivation of the Structural Water Window of Coherence and Biological Activity

This work presents the water-layer extension of the geometric–temporal framework introduced in [1], where physical structure is derived from an underlying period. Water is treated as a nonlinear shared configuration rather than a structureless medium. A minimal stability law is introduced, leading to preferred cluster regimes, temperature redistribution, and the emergence of a structural water window without parameter tuning. The results suggest that the balance between organization and reconfigurability is a natural consequence of geometric–temporal closure, providing a basis for both life-compatible and enzyme-specific regimes. This work represents a second step in a broader program connecting fundamental geometry to physical, chemical, and biological behavior.
