This is the single source of truth for every human and silicon working on Nexus. Read it. Internalize it. Build to it.

1. Project Vision (Non-Negotiable)

Nexus OS is the operating system of Libertaria's future: Military-grade security and modularity. Fast boot. No bloat. Hardened kernel. Zero GNUs given. A system designed to mean something. We do things the right way—correctness over speed.
The default Desktop uses KDE with systemd and is immutable and offers the nip package manager with NexusCells + Flatpak as preferred packages.
The Pro Desktop is using Niri & Hyprland WM with only nip package manager.
The cloud enabled Servers are containerd / podman first and are especially suited for Kubernetes and IOT like deployments, but with container-agnostic pledge/unveil enforcement to go beyond Linux GPL limitations.

We build Rumk — the hypervisor that never dies.
Everything else is a signed, hot-loadable module on top.
One codebase morphs into every profile from 8-bit MCU to quantum cluster.
No forks. No rewrites. No legacy debt.

We enforce the Three Doctrines at hardware level:

1. Absolute Provenance — Variant-CID is eternal truth.
2. Deterministic Ledger — ProvChain logs every breath.
3. Computable Trust — Pledge/unveil + signed Tracks = automatic enforcement.

2. Product Family (All Built by Nexus Build Toolkit)

Profile	Size	Target	Key Traits	Status
Nexus Tiny	256 B – 32 KB	8-bit MCU → single sensor	One NPS, no OS	Q2 2026
Nexus Micro	180 KB – 1.2 MB	Embedded (Pi, VisionFive, satellite)	Rumk + 3–10 NPLs (drivers)	✅ Prototype
Nexus Core	4–8 MB	Workstations / servers	Rumk + Dragonfly SMP + full NPKs	Q3 2026
Nexus Fleet	8–40 MB	Clusters / quantum farms	Rumk nodes + ProvChain Network	Q4 2026
Nexus/Unikernel	280 KB (v0.9)	Aerospace / radiation-hardened	Hybrid Nim+Zig, static musl, SMP	✅ COMPLETE

All profiles share the same /Programs/App/Version/ hierarchy and .np* package format.

Box Distributions (OS Flavors)

Box	Base	Target	Status
🟦 NexBox	Linux-musl + OpenBSD userland	Desktop, Cloud, Kubernetes	🚧 Q1 2026
🟧 OpenBox	Pure OpenBSD 7.x	ARM64 appliances, satellites	🚧 RPi5 Prototype
🟪 DragonBox	DragonflyBSD + HAMMER2	Proxmox killer, enterprise storage	🔮 Q3 2026

See docs/BOX-PROFILES.md for detailed architecture.

3. Core Architecture (Locked)

Component	Technology	Reason / Status
Hypervisor	Rumk (Nim, ~1700 LOC)	Frozen core, 12 entries + 1 meta-slot
SMP	DragonflyBSD LWKT message-passing	Zero contention, scales to 256 cores
Security	Pledge/unveil + Landlock-style per NPL	Least privilege by default
Ledger	ProvChain (CID + Ed25519 + GPS time)	Immutable audit trail
Upgrade Path	BEB (Boot Extension Block) – updatable microcode	Core Rumk never changes
Driver Model	NPLs (Nip Libraries) – isolated VMs, 9P communication	Crash = restart VM, no panic
App Model	NPKs (Nip Packages) – userland containers	NipCells evolved
Package Manager	nip – grafts Linux/Windows/Nix/everything → .np*	Universal ecosystem day one
Build System	nexus build toolkit (Nim)	One command → any profile
Bootloader	nexus-boot (forked Limine, stripped)	<300 LOC, multi-arch, optional splash
Privilege Modes	Nim wrappers for RISC-V M/S/U modes	Deterministic isolation, radiation tolerance
Interrupt/Scheduling	Zig-like assembly + Nim logic	ECC scrubbing, enforced determinism
Toolchain	Nim + Zig grafting	Cross-compile ease, no deps

4. Package Taxonomy (Human-Readable Hierarchy)

Type	Label	Purpose	Proximity to Metal	Example
NPS	Nip Sensor	Tiny, single-purpose	Direct MMIO	Temperature probe
NPL	Nip Library	Drivers / filters	One hop (9P)	iwlwifi, NDIS printer
NPX	Nip eXtension	Hot hooks (eBPF replacement)	Trap dispatch	Packet filter, tracing
NPM	Nip Module	Pure logic	No hardware	Orbital math
NPK	Nip Package	End-user apps	Full sandbox	Firefox, KDE
NPI	Nip Interface	API bridges	Optional	HTTP, gRPC

5. Immediate Roadmap (Next 6 Months – Non-Negotiable)

Quarter	Milestone	Deliverable	Status
Q4 2025	Rumk v0.9	Zig runtime, musl static, unikernel foundation, NPL, SMP	✅ COMPLETE
Q1 2026	Rumk v1.0	Radiation hardening, VisionFive 2 boot, dual-bank OTA	🚧 In Progress
Q1 2026	nexus-boot v1	Multi-arch, Micro ISO generation	✅ COMPLETE
Q2 2026	Nexus Micro ISO	Satellite-ready demo for ESA Hungary	🎯 Target
Q3 2026	Nexus Core	KDE/Hyprland workstation with full driver graft	🔮 Planned

Dec 27, 2025 Achievement: Rumk v0.9 Phases 1.1-5 complete. 280KB unikernel verified in QEMU with SMP telemetry, NPL lifecycle, and ProvChain logging.

6. Development Principles (Law)

• Speed > Perfection until prototype boots
• Pragmatic over purist — graft what works, harden later
• One codebase, many targets — no per-arch forks
• Every commit must produce a bootable image
• Human-readable labels — NP* taxonomy mandatory
• Respect architectures, set limits — docs explain why

7. Repository Structure

We are not building another OS.
We are building the last hypervisor humanity will ever need.

🚧 Current Status: nip MVP Achieved

nip 1.0 MVP is complete! The package manager is ready with:

• ✅ Git LFS support (auto-detect, auto-pull)
• ✅ Configurable recipe repos (NIP_RECIPE_REPO)
• ✅ Bootstrap CLI for package manager tools (nix, pkgsrc, gentoo)
• ✅ Universal package grafting from Nix, PKGSRC, Pacman

nexus build toolkit is ~50% complete.

What is NexusOS Toolkit?

A revolutionary suite of tools that brings together the best of multiple package ecosystems with a vision for AI-First Autonomous Operations:

• NIP (Nexus Integrated Package Manager) - Universal package management
• Nexus - System compilation tool (coming soon)
• UTCP (Universal Telemetry and Control Protocol) - AI-driven autonomous management (v2.0)

🎯 The Vision: AI-First Package Management

NexusOS Toolkit is building toward a future where AI SysOps autonomously manage your systems:

• Self-Monitoring: Continuous integrity verification and health monitoring
• Self-Healing: Automatic detection and correction of configuration drift
• Self-Optimizing: AI-driven performance tuning and resource allocation
• Zero-Touch Operations: Autonomous updates, maintenance, and troubleshooting

This vision will be realized through UTCP, a secure bidirectional protocol enabling AI controllers to monitor telemetry and execute commands on managed nodes. Think of it as "self-driving infrastructure" - your systems maintain themselves while you focus on innovation.
