Lasimeri/Mechanical-Jev

Rust client, CLI, TUI, and eval harness for Jev System One questions.

Automated README summary

Automatically summarized from the README on 26 Sept 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.

What it is

A Rust client library, `mjev` CLI, terminal interface, and evaluation harness for asking Jev System One questions. It sends a state and typed questions to a local Intel Phi Jev server and returns typed probabilities, never generated text.

How it uses Jev

Jev answers Noul (probability a yes/no statement is true), Choice (one option of up to 255, every option's probability, confidence), and Score (ordered rubric of 2 to 10 levels, expected level, every level's probability, confidence). The client sends a state and questions via `POST /v1/systemone`; responses are used in code as typed probabilities.

Primitives:noulchoicescore

Technique worth stealing

Use typed questions with calibrated probabilities instead of generated text for decision-making.

Try it

Run `make setup` then `mjev` to open the TUI; try `e`, Enter, F5.

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.
