Amazon Elastic File System (elasticfilesystem) restJson1 control plane
for fakecloud.
The full 31-operation EFS Smithy model: file systems (with the async
creating -> available lifecycle, size, performance/throughput modes,
encryption, and replication-overwrite protection), mount targets (one per
Availability Zone per file system, each with a synthesized IP address,
network interface, and VPC/AZ derived deterministically from its subnet),
access points (POSIX user + root directory), lifecycle configuration,
backup policy, file-system resource policy, replication configurations,
resource tagging (both the resource-id tagging API and the deprecated
per-file-system Create/Delete/Describe tags API), and account
preferences.
Requests are routed to an operation by HTTP method + @http URI path;
path labels are captured positionally and query parameters are read from the
raw query string so repeated multi-value keys (tagKeys=a&tagKeys=b)
survive intact. Everything is real, persisted, account-partitioned state:
every Create/Put/Update is reflected by its Describe, every Delete
deletes, and AWS's async lifecycle is modelled by returning the transient
creating state and settling to available on the next describe (with
in-flight transitions reconciled on restart).
