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

export AWS_ENDPOINT_URL=http://localhost:5555
aws rds describe-db-instancesCurrent Network Resource Stub Semantics
RDS currently stores database subnet groups and security group references inside RDS state.
- DB subnet group operations store subnet IDs and return RDS-local subnet group data.
- DB instances and clusters store DB subnet group names, classic DB security group names, and VPC security group IDs as request metadata.
- Security group ingress operations record RDS-local authorisations and do not mutate EC2 security groups.
- The implementation does not consult
winterbaume-ec2state 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
