SC LABS / OPEN-SOURCE PROOF OF CONCEPT / ALPHA.2

SC NODE — SC LABS open-source runtime proof of concept

The runtime proof
that came before ARKTOR Core.

SC NODE remains the public Rust proof of concept that controlled routing, tools, permissions and audit can coexist with near-direct model performance. It marks where that direction became real in public code and still stands on its own as an open-source reference.

Version 0.1.0-alpha.2 is verified on Windows and Linux. Ollama and NVIDIA NIM are live-tested; OpenRouter catalog and schema handling are verified, with authenticated completion still pending. SC Node is not the current ARKTOR runtime: it is the public proof that preceded the newer, smaller ARKTOR Core foundation.

VERIFIED 5 AUGUST 2026

Alpha.2 is verified across Windows, Linux, public API gates and reproducible benchmarks.

The current main branch is protected by required Windows and Linux CI checks, an external public-API consumer, Rustdoc and package dry-run gates, and published raw benchmark evidence.

RUN IT YOURSELF

Public source. Reproducible checks.

SC Node requires Rust 1.85 or newer and provides locked build, CI, public-API and benchmark verification paths.

PUBLIC ALPHA

Useful proof, not a current SC LABS product foundation.

SC Node remains an experimental open-source reference. ARKTOR is the current product direction.

Verified

  • Version 0.1.0-alpha.2
  • Windows and Linux CI gates
  • Controlled tool execution and provider routing
  • Published benchmark evidence

Still experimental

  • macOS remains unverified
  • Some provider and streaming paths remain incomplete
  • Memory integration and additional hardening remain open
  • Rust APIs are still alpha

FAQ

What SC Node is today.

Is SC Node the current ARKTOR runtime?

No. SC Node is the earlier public proof of concept. ARKTOR is the current product direction.

Is SC Node open source?

Yes. Version 0.1.0-alpha.2 is available in the public GitHub repository under the MIT licence.

Is it production ready?

No. It remains an experimental public alpha with verified Windows and Linux evidence.
