FDM.3:11 - SoTA-Echoing

The practice question is how to turn financial terms into inspectable event behavior. The selected line adopts ACTUS’s distinction between terms and the scheduled contractual events derived from them. It changes §§4.2–4.3 by making conditions, state and event consequences explicit. Actual use of a particular ACTUS contract type requires checking its specification and encoding.

At comparable first-case effort, deriving two qualified event rows is more useful than mapping an unexplained “loan amount” into a cash-flow field. An executable model is preferable when the relevant branching and repeated calculations justify its cost.

FDM.4 supplies the separate actual-effect question. Reopen the event model when terms, initial state, event ordering or a material scenario assumption changes.
