Cervus is currently in the active development phase. The kernel implements core low-level primitives required for a stable execution environment:
### Core Architecture
- *Boot Protocol:* Utilizes the [Limine](https://github.com/limine-bootloader/limine) bootloader (Barebone profile).
- *Memory Management:*
- *PMM:* Bitmap-based Physical Memory Manager.
- *VMM:* Virtual Memory Management with 4-level paging support.
- *CPU Initialization:* Custom GDT (Global Descriptor Table) and IDT (Interrupt Descriptor Table) implementation.
- *Acceleration:* Native support for *SIMD* instructions (SSE/AVX) with proper state saving.
