300 2.6 Operator Guidance Engine To bridge the gap between model predictions and practical operator actions, the system incorporates an operator guidance engine that translates continuous numerical outputs into clear, actionable coaching messages. This component is implemented as a lightweight, rule-based layer to ensure transparency, predictability, and ease of validation in safety-critical environments. The guidance engine evaluates real-time vehicle telemetry in conjunction with the model outputs and triggers contextual feedback based on predefined operational rules. Table 1.
