C++23 Native Kernel

45/45 Test Suites Passing

Zero Telemetry

< 32 MB Idle RAM

MIT Clean-Room

The Cleanest NT Architecture on Earth.

An open-source, zero-telemetry, modern C++23 operating system executive built as a strict clean-room implementation. Resurrecting Dave Cutler’s 1988 DEC MICA & PRISM architecture for bare-metal modern computing.

Bare-Metal UEFI GOP Boot Splash

1988 DEC MICA / PRISM heritage tribute rendered via high-resolution 32-bpp linear framebuffer.

Interactive ConHost Win32 Desktop

Zero-telemetry executive running native commands, process scheduling, and real-time graphics.

Uncompromised Systems Engineering

Built from the ground up in modern ISO C++23 with strict RAII, compile-time type safety, and zero legacy bloat.

⚡

Pure Object Manager (`ob/`)

Dave Cutler's clean handle-based namespace hierarchy (`\Device`, `\DosDevices`, `\KernelObjects`, `\BaseNamedObjects`) with type objects, handle tables, and atomic reference counting.

🛡️

Security Trinity (SAM, LSASS, Winlogon)

RFC 1320 MD4 NT-Hash generation, SAM user database, LSASS MSV1_0 authentication package with NTLM challenge/response, token synthesis, and secure desktop isolation.

🎮

PrismX & Prism3D Graphics

Clean-room DXGI presentation pipeline and Direct3D 11/12 execution engine. Features a built-in software reference rasterizer with Gouraud interpolation, depth testing, and WDDM kernel thunking.

💾

NTFS & FAT32 File Systems

Full 1024-byte MFT record parsing, runlist decompressor, B-Tree index traversal, FAT32 cluster chains, and Virtual File System (VFS) volume routing.

🌐

NDIS 6.x & TCP/IP Stack

Dual-stack IPv4/IPv6 networking, ARP resolution, ICMP echo, UDP datagrams, full RFC 793 11-state TCP state machine, and Winsock 2 (`ws2_32.dll`) userland bridge.

⚙️

Service Control Manager (SCM)

Clean-room `services.exe` daemon with dependency resolution, service state machines, shared `svchost.exe` process host isolation, and RPC over Named Pipes.

PrismX & Prism3D Graphics Subsystem

Named in tribute to Dave Cutler's 1988 DEC PRISM project. Complete clean-room graphics compatible with Microsoft's MIT-licensed DirectX-Headers and DirectXTK.

🖥️

PrismX Presentation Pipeline

DXGI-compatible presentation layer implementing IDXGIFactory1, IDXGIAdapter1, IDXGIOutput, and IDXGISwapChain. Supports 32-bpp BGRA double/triple buffering, FLIP_DISCARD presentation models, and direct blitting to the UEFI GOP linear framebuffer.

📐

Prism3D Barycentric Rasterizer

Direct3D 11/12 runtime engine with vertex/index buffers, viewports, render target views, and depth-stencil views. Built-in high-precision software reference rasterizer scan-converts 3D geometry with sub-pixel Gouraud RGB color shading and Z-buffer testing.

🔺

PrismVK & Khronos Vulkan 1.3

Standard Khronos Vulkan ICD Loader (vulkan-1.dll) with registry driver discovery, discrete GPU device enumeration (1.3.0, 8GB VRAM), VK_KHR_win32_surface windowing, and VK_KHR_swapchain frame presentation.

Native Command Prompt Shell

Zero telemetry, blazing fast execution of native commands, unmodified 64-bit Windows PE binaries, and hardware diagnostics.

100% Clean-Room Provenance

Engineered strictly for software interoperability under legal fair use standards.

Legal Interoperability Precedent: In Google LLC v. Oracle America, Inc. (593 U.S. 1, 2021), the Supreme Court of the United States held that reimplementing declaring code, functional method signatures, and API structures for binary interoperability is protected fair use as a matter of law.

Official MIT References: System call interfaces, GUIDs, and data structures are derived strictly from Microsoft’s official MIT-licensed open-source repositories: microsoft/win32metadata and microsoft/DirectX-Headers.

Clean-Room Sentinel CI: Every pull request is verified by an automated provenance auditor (clean_room_sentinel.js) to guarantee zero decompiled code, leaked materials, or proprietary binary blobs ever enter the codebase.
