#### Job Description
> (작업 내용)

The issue only describes administrator access to create, edit, and delete cooking courses and recipes; its task body contains no implementation files, tests, acceptance criteria, or requirements. Start by clarifying the permission rules and expected course and recipe behavior, then locate the relevant server entry points and define tests that show each operation is restricted correctly.
