Server-mode usage

Start winterbaume-server and point the AWS CLI at it:

cargo run -p winterbaume-server -- --host 127.0.0.1 --port 5555

export AWS_ENDPOINT_URL=http://localhost:5555
aws dsql list-clusters

Current Network Resource Stub Semantics

DSQL currently exposes a VPC endpoint service-name API shape but does not implement the network path.

• GetVpcEndpointServiceName is routed as not implemented and does not return a service name derived from cluster state.
• Cluster records do not allocate or track VPC endpoints, subnets, security groups, or PrivateLink attachments.
• The generated model contains clusterVpcEndpoint, but current handlers do not populate it from EC2 or DSQL state.
• The implementation does not consult winterbaume-ec2 state for these identifiers, so it does not check that referenced VPCs, subnets, security groups, VPC endpoints, network interfaces, or load balancers exist, belong to the same VPC, or are in a usable lifecycle state.

Example

use aws_sdk_dsql::config::BehaviorVersion;
use winterbaume_core::MockAws;
use winterbaume_dsql::DsqlService;

#[tokio::main]
async fn main() {
    let mock = MockAws::builder().with_service(DsqlService::new()).build();

    let config = aws_config::defaults(BehaviorVersion::latest())
        .http_client(mock.http_client())
        .credentials_provider(mock.credentials_provider())
        .region(aws_sdk_dsql::config::Region::new("us-east-1"))
        .load()
        .await;

    let client = aws_sdk_dsql::Client::new(&config);

    let resp = client
        .list_clusters()
        .send()
        .await
        .expect("list_clusters should succeed");
    println!("DSQL clusters: {}", resp.clusters().len());
}
