# 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.
