systemone (open typed-decision layer)

An open typed-decision layer with choice, score and noul questions, calibrated probabilities and one batched call, built as a numpy-only base with eight swappable engines. The README positions it as rebuilding Jev's closed API shape on hardware you control.

This is one of several Jev listings for the same project. The canonical entry is Systemone — codesoda.

Highlights

  • Open typed-decision layer: choice, score and noul questions with calibrated probabilities, honest uncertainty, one batched call.
  • TypeSafe's Jev is described as a closed API; this package rebuilds that shape on hardware you control, the README says.
  • Eight swappable engines: local GLiClass, SGLang, JEV decision models, JevK5, Kev, Cloudflare Clef, a CPU-only ONNX judge and decider-4b.
  • DecisionLoop in systemone/loop.py runs See > Decide > Act with cache-friendly prefixes and compressed memory.
  • First job: a typed decision about a state — support triage, a guard before a side effect, citation grounding; routing is optional.

Watch out

README and GitHub metadata reviewed 2026-10-17; the digest cuts off inside the DecisionLoop description, so the loop's remaining guarantees, install instructions and API are not captured. No benchmarks or accuracy numbers appear.
