1.4.4.1. Unified Repository Permission System

As the number of module repositories grows, a unified and efficient repository permission system becomes crucial.

On platforms like GitHub, the recommended practice is to manage permissions using an "Organization + Team" structure.

• GitHub Team Responsibilities: Each repository should have corresponding teams defined by function (Admin, Contributor, Read-only). These teams should be created even if they currently have no members. Assigning permissions directly to individual accounts is prohibited; all administrative privileges must be granted by adding accounts to the relevant teams.

• Principle of Least Privilege: Teams should only hold write permissions for the module repositories they are responsible for, retaining only read permissions for other modules to prevent accidental modifications.

• A Central High-Level Management Team (Central Maintainers Team): To ensure the stability and consistency of the module system during critical moments, a central governance team with global permissions should be established. Composed of senior architects, heads of platform engineering, or DevOps leaders, this team holds read/write access to all module repositories. They can intervene and lead maintenance efforts in cases of long-term neglect, critical issues, or cross-module coordination requirements.

• Unified GitHub App: Certain automation tasks (such as automatic documentation generation, label management, public file synchronization, and execution of restricted operations) must be executed via a GitHub App to ensure security.

The ultimate goal is to achieve management that is both decentralized and unified: maintaining autonomy for individual modules in development while enforcing unified oversight through standardization and tooling in governance.
