A physical computing architecture is disclosed in which emergent resulting states produced through transient physical evolution within a medium lacking stored computational routing topology are directly coupled to downstream systems. The resulting states arise from physical constraint resolution rather than predefined computational functions, and are therefore qualitatively distinct from states produced by conventional analog circuits such as thermocouples or operational amplifier circuits. Such emergent resulting states may influence downstream systems including actuators, processors, memory elements, communication systems, and other physical media without requiring informational extraction, decoding, or symbolic interpretation as a prerequisite. Observation and decoding may occur concurrently with direct state coupling but are optional rather than architecturally required. In certain embodiments the physical medium exhibits history-dependent parameter field modification from prior excitation. The disclosed architecture represents the direct-coupling branch of a three-branch framework comprising state formation, state interpretation, and direct state coupling, arising from the non-stored-topology physical computation family.
