# Cross-Course Merger The cross-course merger combines multiple course-like inputs covering the same subject area. ## Goal Build a stronger draft topic pack from several partially overlapping sources. ## What it does - merges normalized source records into course bundles - merges course bundles into one topic bundle - compares repeated concepts across courses - flags terminology conflicts and overlap - emits a merged draft pack - emits a cross-course conflict report ## Why this matters No single course is usually ideal for mastery-oriented domain construction. Combining multiple sources can improve: - concept coverage - exercise diversity - project identification - terminology mapping - prerequisite robustness ## Important caveat This merger is draft-oriented. Human review remains necessary before trusting the result as a final domain pack.
