# Source Term
**Entity class:** Transport And Oden Dual-Use Layer concept
**Source Term** is a tradecraft concept describing a human role, access path, intermediary, or reporting relationship within an operational network. Within a predictive graph, Source Term helps separate recorded evidence from the hidden state inferred from that evidence.
## Counterterrorism predictive-graph role
Transferability is documented at the level of mathematical method; a particular counterterrorism deployment remains a separate operational proposition requiring direct evidence. The analytic state should distinguish ground truth, observed evidence, inferred state, and predicted state.
