verdix

Eligibility-as-code: a domain-agnostic engine that turns messy qualification rules into explainable, auditable verdicts with evidence.

• Domain-agnostic — the engine contains zero domain vocabulary
• Four-valued verdicts — pass, fail, unknown, review
• Confidence propagation — every verdict carries confidence scores
• Provenance tracking — every decision is traceable to its source

Install

npm install verdix

Usage

import { evaluate, governmentJobPack } from "verdix";

const result = evaluate(governmentJobPack, {
  age: 24,
  education: "bachelor",
  // ...subject attributes
});

console.log(result.status); // "pass" | "fail" | "unknown" | "review"
console.log(result.confidence); // overall confidence
console.log(result.evidence); // per-rule trace with provenance

API

• evaluate(pack, subject) — run a pack's rules against a subject, returning an aggregated verdict with evidence
• evaluateRule(rule, ctx) — evaluate a single rule
• foldStatus / overallConfidence / summarize — aggregation helpers
• logic — Kleene three-valued logic primitives
• governmentJobPack, scholarshipPack — example domain packs
