v0.4.0 — Software 3.0 reference implementation (Karpathy framing)

What's new in v0.4.0

Repositioned as the OSS evaluation loop for multi-persona AI agents — directly mapping to Karpathy's Software 3.0 framing (Sequoia AI Ascent, April 20, 2026).

• Paste a decision → get 5 persona verdicts in parallel
• Watch personas disagree → optional Fable 5 Oracle adjudicates
• Brier-audit every voice when the real-world outcome resolves
• Shipped 6 months before Anthropic's "advisor strategy" beta (announced June 9, 2026)

Install

```bash
npm i council-diff
```

Why this is a Software 3.0 artifact

Software 3.0 has no compiler error or unit test that catches a hallucination. The agentic engineer's job: design specs precise enough that ambiguity has nowhere to hide, then build the evaluation loop that catches model drift. council-diff is the smallest reproducible version of that loop.
