# Transport as a General Predictive Architecture
**Entity class:** Cross-domain mathematical architecture
## Definition
**Transport as a general predictive architecture** is the abstract chain:
**source → medium or network → propagation or transmission → exposure → receptor → response → observation → inverse inference → forecast**
The chain can recur across physically different domains without making their entities equivalent. In radiation modeling, particle transport equations and reduced-order surrogates are predictive machinery; radiation is the transported quantity; matter and geometry form the medium; a person or asset is a receptor; dose or damage is response; measurements provide observations; inverse methods estimate hidden parameters; and uncertainty quantification qualifies inference.
In epidemic modeling, the transported object is infection through contacts. In complex-contagion models of radicalization, the transmitted content is informational and social, and adoption can require reinforcement. The domain assumptions, causal mechanisms, evidence rules, and legal consequences differ.
## Evidence Boundary
Oden documents radiation prediction and epidemic modeling by Bui-Thanh. Counterterrorism scholarship independently documents epidemiological and network models of radicalization. The generalized architecture is a structural synthesis, not evidence that Oden or DTRA substituted ideological variables into nuclear code.
