@heybeaux/sonder-adapter-parliament

Sonder adapter for Parliament (multi-neurotype deliberation). Fills event.reasoning on every SonderEvent.

Install

npm install @heybeaux/sonder-adapter-parliament @heybeaux/sonder-core

What it fills

event.reasoning = {
  model:      string;    // primary model used
  neurotypes: string[];  // active neurotype IDs in deliberation
  consensus:  boolean;   // true if all neurotypes agreed
  dissent:    string[];  // neurotype IDs that dissented
  osi:        number;    // Opinion Shift Index (0–1, echo-chamber detection)
  rounds:     number;    // deliberation rounds taken
}

Usage

import { ParliamentAdapter } from '@heybeaux/sonder-adapter-parliament';
import { createRuntime } from '@heybeaux/sonder-sdk';

let lastDeliberation = null;

const runtime = createRuntime({
  adapters: [
    new ParliamentAdapter({
      getLastDeliberation: () => lastDeliberation,
    }),
  ],
});

// After Parliament deliberates, set the result:
lastDeliberation = {
  model:      'claude-opus-4-7',
  neurotypes: ['empiricist', 'skeptic', 'synthesizer'],
  consensus:  true,
  dissent:    [],
  osi:        0.38,
  rounds:     2,
};

Config

interface ParliamentAdapterConfig {
  // Return the last deliberation result before each event.
  // Return null if no deliberation occurred — event.reasoning will be zeroed.
  getLastDeliberation(): ParliamentDeliberationSnapshot | null;
}

interface ParliamentDeliberationSnapshot {
  model:      string;
  neurotypes: string[];
  consensus:  boolean;
  dissent:    string[];
  osi:        number;
  rounds:     number;
}

Opinion Shift Index (OSI): measures how much neurotype opinions shifted during deliberation. Low OSI (<0.2) suggests echo-chamber dynamics. High OSI (>0.7) suggests genuine disagreement that reached resolution.

Compliance

event.reasoning.* answers the regulated question "What did the agent decide and why?" required by ESMA Feb 2026 and FCA Consumer Duty.
