+"""Data migration script to fix corrupted username fields.
+
+This script fixes the bug where user.username was incorrectly set to full_name
+instead of preserving the actual username. It migrates existing users by:
+1. Setting username to a slug version of full_name (e.g., 'sarah-johnson')
+2. Clearing full_name to empty string (will be collected via profile edit)
+
+Run this script once to fix existing database records.
