Privacy + safety layer on top of v0.3.0 Fable 5 Oracle.

Read together with the v0.3.0 release notes for the Oracle backstory. v0.3.1 is the small but load-bearing privacy/transparency pass.

What's new

  • 30-day data retention disclosure — Mythos-class models (which Fable 5 Oracle uses) carry an explicit 30-day retention window on Anthropic's side. Council-diff now surfaces this with a data_retention: "30day-mythos" field on every response so privacy-positioned downstream apps can branch on it.

  • safeMode silent downgrade — pass safeMode: true to force Sonnet 4.6 as the Oracle fallback instead of any Mythos-class model. No 30-day retention, slightly weaker adjudication, fully opt-in. Designed for apps that can't ship Mythos data to a third-party.

  • API surface stable — no breaking changes from v0.3.0. Add the two new optional fields and you're done.

Pairs with

  • polymarket-brier-skill — calibration layer for prediction markets. Pass council-diff output through Brier audit to track which voice has been predictive over 30 days.
  • solo-founder-os — the agent stack that birthed both projects.

Install

```bash
npm install council-diff@0.3.1
```

Hackathon

This release is the version going into the Band of Agents Hackathon submission (deadline 2026-06-19) under the "3+ agents collaborating" track. The Oracle + 5 voices = literally 6 agents in disagreement-and-resolve shape.
