🎓 Educational Insights
📌 DAG Property: Notice there are no cycles—a patient does not return to admission during a single encounter. This ensures each stage progresses forward in time.
⏰ Temporal Progression: Each stage represents a point in time, moving forward chronologically. The pathway models real-world clinical workflows where care episodes have a clear beginning and end.
🎯 Healthcare Context: DAGs model workflows where states progress without reverting to earlier stages in the same episode of care. The optional retest edge (dotted) shows conditional paths without creating true cycles.
