SupremeDreamZ/jev-fastloop

Cheap fail-open semantic edge layer for Jev decisions.

Automated README summary

Automatically summarized from the README on 21 Sept 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.

What it is

A stdlib-only Python decision service for developers using Jev (TypeSafe System One). It wraps typed questions with a confidence policy, per-lane decision logging, a blind eval harness, and a skill router over large skill rosters.

How it uses Jev

Jev answers typed questions (noul, choice, score) on a given state. The service returns calibrated probabilities, applies a confidence policy to route each answer to action, escalate, or abstain, and logs every decision for later threshold tuning.

Primitives:choicescorenoul

Technique worth stealing

Fuse Jev as a second semantic signal with deterministic retrieval; decompose judgments into atomic questions and combine with code.

Try it

export OPENCODE_ZEN_API_KEY=... then run python3 eval_preflight.py ground_truth.json or skill_router.py.

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.
