File	Description
lib/tasks/seeds_helper.rb	Adds jim_dun UUID to TEST_USERS hash with comment indicating "user with no school"
lib/tasks/test_seeds.rake	Adds cleanup logic for jim_dun's roles and school; refactors array syntax in where clauses

[Copilot]

The SchoolClass cleanup only handles the primary school_id, not the teacher_signup_school_id. If jim_dun has created a school with classes and class members, those won't be cleaned up before the school is destroyed at line 40.

Consider extending the cleanup to include both schools:

school_class_ids = SchoolClass.where(school_id: [school_id, teacher_signup_school_id].compact).pluck(:id)

Suggested change

	school_class_ids = SchoolClass.where(school_id:).pluck(:id)
	school_class_ids = SchoolClass.where(school_id: [school_id, teacher_signup_school_id].compact).pluck(:id)
