Casual OS is an AI platform that turns natural-language specs into production-ready apps—and runs them safely at scale. It auto-generates architecture (DAG), code, tests, and a policy manifest (egress allowlists, data handling, budgets, SLOs). Apps execute in a zero-trust sandbox with audit logs, monitoring, and deterministic replay. A visual editor lets anyone refine UI/flows; developers can export clean TypeScript. Publish to a trust-badged marketplace with monetization.
On the same platform, Casual Play enables rule-editable, competitive games (e.g., chess variants). Creators define rules in a safe DSL compiled to a deterministic, server-authoritative engine with fairness checks, anti-cheat, and replay/appeals. Skins and rules ship separately, so players customize looks without breaking integrity.
