Get the sequence wrong and you either frustrate students (hints too vague, too few) or steal their learning (hints too specific, too early). The output includes the complete hint cascade (typically 3–5 levels from general strategic guidance to specific procedural nudge), a design rationale explaining the cognitive function of each level, trigger conditions (when each hint fires), and …
