Governance Packs

Governance packs are data-driven rule definitions — no executable code.

Built-in Packs

• eu-ai-act-v1 — EU AI Act Article 12 compliance (7 rules)
• minimal — Basic logging for testing

import { verify } from '@brivora/verify';

// List available packs
const packs = verify.listPacks(); // ['eu-ai-act-v1', 'minimal']

// Load a pack
const pack = verify.loadPack('eu-ai-act-v1');

Custom Packs

const customPack = verify.createPack({
  name: 'my-governance',
  version: '1.0.0',
  description: 'Custom governance rules',
  rules: [
    {
      id: 'model-allowlist',
      name: 'Approved models only',
      description: 'Only allow approved AI models',
      phase: 'pre',
      severity: 'critical',
      evaluate: { type: 'model_allowlist', models: ['claude-sonnet-4-5-20250929', 'gpt-4'] },
    },
  ],
  scoring: {
    dimensions: [{ name: 'compliance', rules: ['model-allowlist'] }],
    threshold: 1.0,
    weights: { compliance: 1.0 },
  },
});

const result = await verify.govern(fn, { governance: customPack });

EU AI Act v1 Pack

The eu-ai-act-v1 pack maps to Article 12 requirements for high-risk AI systems:

Rule	Article	Severity
Automatic event logging	Art. 12(1)	Critical
Event traceability	Art. 12(2)	Critical
Monitoring capability	Art. 12(3)	High
Human oversight data	Art. 14	High
Model identification	Art. 13	High
Content safety baseline	—	Medium
PII detection	—	Medium

Scoring dimensions: transparency (30%), traceability (30%), safety (25%), privacy (15%). Passing threshold: 0.7.
