- Implemented SFS Driver (core/fs/sfs.nim): - Mount logic (Sector 0 Superblock check). - List logic (Sector 1 Directory table). - Implemented Userland Formatter (nipbox.nim): - 'mkfs' command to write SFS1 Superblock. - Fixed 'virtio_block' logic: - Corrected Descriptor flags (VRING_DESC_F_WRITE for Read Buffers). - Fixed Async/Sync Conflict in 'libc_shim': - Added 'nexus_yield()' to block syscalls to prevent stack corruption before kernel processing. - Integrated SFS into Kernel startup. |

Rumpk: The Modular Unikernel
"The Kernel is a Library. The App is the OS."
Status: EXPERIMENTAL
Languages: Zig (L0) + Nim (L1)
Design: POSIX-hostile, Military-grade

Key Features
- Adaptive I/O: War Mode (polling) ↔ Peace Mode (interrupts)
- Disruptor Ring: Lock-free inter-fiber communication
- SipHash IDs: Collision-resistant process identification
- Ed25519: Only signed code executes
