01
Boot & Kernel
Establish the boot path and the fundamental privileged execution environment of snarOS.
Independent operating system project
snarOS
An operating system
built from the ground up.
A long-term systems engineering project focused on security, isolation, reliability, performance and a foundation designed to evolve.
CURRENT STATE
The project starts here.
snarOS is currently at the foundation stage. This website will evolve together with the operating system and will reflect actual implementation progress.

CURRENT MILESTONE
Project Foundation
Define the architecture, development environment, system boundaries and Version 1.0 requirements.
Planning
VERSION 01
What must exist
What must exist
before 1.0.
Version 1.0 is not a visual milestone. It is a technical release gate. Every major subsystem must be implemented, tested and documented before the release is considered complete.
02
Memory
Physical memory, virtual memory, address spaces, allocation and memory protection.
03
Processes
Processes, threads, scheduling, context switching, synchronization and inter-process communication.
04
Security
Strong boundaries between components with least privilege, isolation and explicit authorization mechanisms.
05
Storage
Device abstraction, filesystem interfaces, persistent storage and recovery mechanisms.
06
Networking
Network devices, protocol stack, sockets and controlled communication between systems.
07
Userspace
System services, shell, utilities, runtime interfaces and the initial application environment.
08
Graphics
Display, input, rendering and the foundation for the graphical user environment.
09
Verification
Automated testing, fuzzing, fault testing, benchmarks and release validation.
DEVELOPMENT TREE
One system.
One system.
Many engineering domains.
The project is divided into technical domains so progress can be understood at a glance without hiding the complexity underneath.

VERSION ROADMAP
From first boot
From first boot
to 1.0.
Versions represent technical milestones. A version becomes complete through implementation and verification — not simply because time has passed.
01
v0.0.1
CURRENT
Project Foundation
Establish the architecture, repository, toolchain, development workflow and complete 1.0 specification.
02
v0.0.2
PLANNED
First Boot
Produce the first bootable snarOS image and establish the earliest kernel execution environment.
03
v0.1
PLANNED
Kernel Foundation
CPU initialization, interrupts, kernel runtime, diagnostics and foundational kernel services.
04
v0.2
PLANNED
Memory & Execution
Memory management, address spaces, tasks, context switching, scheduling and initial IPC.
05
v0.3
PLANNED
Storage & Persistence
Storage abstractions, filesystem interfaces, persistent data operations and recovery.
06
v0.4
PLANNED
Userspace
System services, shell, utilities and the initial userspace application model.
07
v0.5
PLANNED
Security Foundation
Process isolation, capabilities, authorization, identity boundaries and security testing.
08
v0.6
PLANNED
Networking
Network devices, protocol stack, sockets and system-level networking interfaces.
09
v0.7
PLANNED
Graphics
Display, input, rendering and the foundation for a graphical environment.
10
v0.8
PLANNED
System Integration
Integrate major subsystems and strengthen stability, diagnostics and recovery.
11
v0.9
PLANNED
Release Candidate
Full-system validation, security testing, fuzzing, benchmarks and release hardening.
12
v1.0.0
RELEASE GATE
First Stable Release
All defined Version 1.0 requirements implemented, verified and documented.
ENGINEERING PRINCIPLES
Build the foundation
Build the foundation
correctly.
The goal is not to make claims that sound impressive. The goal is to build systems that can eventually prove them.
Security by construction
Security boundaries should be part of the architecture instead of being an afterthought.
Failure containment
A failure in one component should not automatically become a failure of the entire system.
Minimal trusted core
Keep privileged code deliberate, understandable and as small as practical.
Measured performance
Performance claims should eventually be supported by reproducible benchmarks.
Observable systems
Diagnostics should make failures understandable instead of mysterious.
Evolution without chaos
Stable interfaces and modular boundaries should allow future capabilities without constantly rebuilding the core.
TECHNOLOGY
The tools behind
The tools behind
the system.
Technology choices will evolve as architecture decisions are validated. These represent the current engineering areas.

RELEASE PHILOSOPHY
Code is not
Code is not
evidence by itself.
A snarOS milestone becomes complete only when the implementation, tests and documentation support it.
