Domain Expert Configuration A domain expert configuration UI exposes the parameters of a complex system — an optimisation algorithm, a planning engine, a simulation — to users who understand the problem domain deeply but have no knowledge of the system's internals. The challenge: the system's parameters are defined in technical terms (weights, thresholds, flags, tolerances). The user thinks in domain terms (how long to wait, when to retry, how to group results). The UI must translate between these two vocabularies — always favouring the user's language. --- The Core Principle: Domain Language…
