# Server configuration

> Configure the standalone server bind, limits, concurrency, timeout, and playground.

The standalone launcher reads `server.yaml` beside the compiled artifact.

```yaml theme={null}
apiVersion: harnest.dev/v1alpha1
kind: Server
http:
  host: 127.0.0.1
  port: 8080
  allowRemote: false
  requestTimeoutSeconds: 300
  maxConcurrentRequests: 8
limits:
  maxRequestBytes: 10MiB
playground:
  enabled: true
```

## Server properties

| Property                     | Controls                           | Default intent    |
| ---------------------------- | ---------------------------------- | ----------------- |
| `http.host`                  | Bind host                          | Loopback only     |
| `http.port`                  | Bind port                          | Local development |
| `http.allowRemote`           | Consent for a non-loopback bind    | `false`           |
| `http.requestTimeoutSeconds` | Request timeout                    | Bounded work      |
| `http.maxConcurrentRequests` | In-process concurrency             | Bounded load      |
| `limits.maxRequestBytes`     | HTTP body and WebSocket frame size | Bounded memory    |
| `playground.enabled`         | Development UI                     | Enabled locally   |

Exact `${NAME}` values are type-checked environment references. Partial interpolation and missing or invalid values fail at startup.

## Configuration boundary

| Put in `server.yaml`    | Configure elsewhere         |
| ----------------------- | --------------------------- |
| Bind address            | Authentication              |
| Timeout and concurrency | TLS                         |
| Request-size limits     | Secrets                     |
| Playground toggle       | Durable storage             |
| Local operator settings | Replicas and network policy |

<Warning>
  `allowRemote: true` only permits the bind. It does not add authentication, TLS, or network policy.
</Warning>

Command flags temporarily override operational properties without changing the compiled source contract.
