AWS Emulator

AWS Emulator is one command, aws-emulator, that serves AWS service APIs over HTTPS on 127.0.0.1:9297. It runs natively only on Linux (RPM or Debian package); on macOS and Windows it runs in a Docker container built from that package; Rust tests can also embed it in-process (embedded mode). The AWS CLI and SDKs work unchanged once a few environment variables point them at it and at the config and credentials files it writes at start. This skill covers getting it running and connected, and answering whether a project (or one operation) will work on the installed build, with evidence.
