Dependency map for a curriculum

Returns the dependency relationships between lesson groupings within a curriculum.

Dependencies represent prerequisite relationships between lesson groupings (units, sections, modules). A dependency from source → target means the target is a prerequisite — it should be taught before the source.

Use this endpoint when you need to:

• Visualize the dependency graph for a curriculum
• Understand prerequisite relationships between units or sections
• Build a dependency-aware course planner or sequencing tool
