Write module interface units, partition units, export declarations, and understand the module dependency graph.

Configure CMake for module scanning, use Ninja dyndep for implicit dependencies, and share BMIs across CI workers.

Distribute precompiled module interfaces, manage ABI compatibility across compiler versions, and version module libraries.

Scale C++ builds with Bazel or Buck2, configure remote execution and caching, and integrate with module-aware toolchains.
