**⚠️ Important Distinction:** `KERNEL_FLAVOR` and `KERNEL_CONFIG_FLAVOR` are different concepts and can be confusing:

- **`KERNEL_FLAVOR`** (also called just `FLAVOR` in branch names): Corresponds to the EVE `PLATFORM` variable and determines the kernel branch (e.g., generic, nvidia-jp5, nvidia-jp6). This is part of the branch name like `eve-kernel-amd64-v6.12.49-generic`.
