## Purpose

BBG protects critical baseband-related partitions and device nodes from unauthorized modifications. It operates at the kernel security module level, intercepting write operations to protected resources.

## Build Integration

When `use_bbg` is enabled in the build workflow, BBG is included in the kernel build. It is enabled by default.
