-> The open target format and runtime for AI-written business apps. Your coding
-> agent writes models, UI, workflows, and permissions as compact typed metadata —
-> [a complete CRM is under 2,000 lines](#why-the-mistakes-dont-ship), so the whole
-> app fits in the agent's context — and strict TypeScript, Zod schemas, and a
-> validation gate catch its mistakes at authoring time. The runtime derives the
-> database, REST API, UI, and MCP server, and enforces permissions and audit on
-> every call.
+> ObjectStack compresses an entire app — data model, UI, workflows,
+> permissions — into typed metadata an AI agent can hold in context, reason
+> about, and refactor whole ([a complete CRM is under 2,000

+> ontology** — an open, versioned definition of your objects, permissions, and
+> flows that you own, not code scattered across a framework. Strict TypeScript,
+> Zod schemas, and a validation gate catch the agent's mistakes at authoring
+> time; the runtime derives the database, REST API, UI, and MCP server, and

 **Everything in this repo is the open stack** — protocol, microkernel, SDK,
-CLI, and the production runtime, Apache-2.0 with no open-core asterisks. You
-can build, ship, and self-host real apps from here alone. Rather have the
-platform run for you, AI Builder and governance included? That's

-runtime environment built on this stack.
+CLI, and the production runtime, Apache-2.0 with no open-core asterisks. The
