Change the World
Public testing · Build in progress. Features, balance, and saved-game compatibility may change.

CW-201 foundation

The product contract comes before the simulation.

Change the World is for single players exploring connected societal consequences. The first experience begins from a versioned world baseline, accepts a bounded action, and explains what changed, when, and why.

Player contract

You define what success means. The simulation reports conditions and consequences without assigning a universal moral score or mandatory ending.

Canonical authority

Only the World Engine may change canonical world state. Domain systems and AI expression cannot bypass consequence resolution.

Reproducible worlds

A run is pinned to explicit product, engine, baseline, package, seed, schema, and tick identities so the same fixture can be replayed.

Versioned saves

Save manifests are validated and fail closed when incompatible. v1 playable worlds persist only in browser local storage and can branch without overwriting a parent.

Explicit non-goals
