# Standalone Greeter Demo

This demo proves the SDK can run without HiveCast, without a managed platform,
and without committed credentials.

Run from the repository root:

```bash
pnpm demo:standalone
```

What it proves:

- the SDK packages build from this repo,
- this package builds against `@open-matrix/core`,
- `matrix run` starts the actor from the package manifest,
- `matrix invoke demo.greeter echo ...` calls the actor over the SDK local
  runtime path,
- all runtime state is written under the demo package's local `.matrix/`
  directory.
