```python
@final
class Discovery
```

Image configuration. A missing discovery response means an older daemon.

## Constructor

`Discovery` declares no `__new__` or `__init__`, so it is not constructed directly: an instance comes back from another call in this package.

## Properties

### `default_user`

```python
default_user: str | None
```

Configured user, or None for the daemon/root default. Resolved per exec.

## Provenance

This page is generated from `bindings/microvms-py/microvms.pyi` by Griffe 2.3.0, run from `site/scripts/gen-reference.mjs` on every `pnpm run sync`, so an edit made here is overwritten by the next run.

To change the page, change the doc comment in the binding's Rust source, then regenerate the declarations with `mise run stubs`. `mise run stubs:check` fails when the committed file no longer matches the source.
