H.1.1 Repository Models

A repository model states which source state and change history are shared.

• A monorepo gives one source-control boundary; it does not imply one product, build system, access domain, or dependency policy.
• Separate repositories strengthen selected governance, confidentiality, or contribution boundaries while adding discovery and coordination work.
• Hybrid models use a primary repository, mirrors, or composed build graphs; name which guarantees cross each boundary.
• Choose from change flow, access, external collaboration, governance, and operating cost—not repository size alone.
