C# client for System One: Decision-1, Jev, open-jev

Automated README summary

Automatically summarized from the README on 13 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.

What it is

A C# port of Microsoft's Foundry quickstart for Microsoft-Decision-1, plus a benchmark that runs the same labeled support tickets through Microsoft-Decision-1, Jev, and open-jev using one client.

How it uses Jev

Jev answers typed questions (choice, score, noul) on a state object. The client sends these to the System One endpoint and returns probabilities, confidence, and usage. The benchmark uses these answers to compute accuracy, Brier score, and latency.

Primitives:choicescorenoul

Technique worth stealing

One client class with three factories for Foundry, Jev, and open-jev, all sharing the same System One contract.

Try it

dotnet test (hermetic, no network). For demo: dotnet run --project src/Decision1VsJev -- demo decision1

Model judgments from README excerpts

Project signals use repository metadata, an existing summary and the first 700 README characters, not the full project. “Not found” means not detected in that material; it does not establish absence. These are the original judgments with recorded models and dates, not source audits or run results.

Evidence

These signals use repository metadata, an existing summary and at most 700 cleaned README characters. ≥ 0.60 means reported in that excerpt; ≤ 0.40 means not found there. The middle band is inconclusive. None is a source-code audit or a test result. The runnable-tool question excludes research experiments; the recommendation question asks for a learning shortlist, not a quality verdict.
