eve-governance (TypeScript)

TypeScript SDK for offline cryptographic verification of EVE AI Core governance artifacts.

Note: This package provides the TypeScript API contract and type definitions. Implementation bodies are stubs; the Python SDK (sdks/governance/) contains the reference implementation.

Installation

npm install eve-governance

Usage

import {
  verifyDecisionCertificate,
  verifyChain,
  verifyItiSnapshot,
  healthBand,
} from "eve-governance";

// Verify a decision certificate
const result = await verifyDecisionCertificate(cert);
console.log(result.valid ? "✓ VERIFIED" : "✗ FAILED");

// Health band
console.log(healthBand(87.5));  // "GOOD"
