It is a Rust binary you install from a Debian or RPM package, point <code>AWS_ENDPOINT_URL</code> at, and run your integration tests against without an AWS account. Anyone who has run that category of tool before knows the failure mode: the tests go green locally and the stack falls over on real AWS.</p> <p>What makes this one unusual is that AWS publishes the evidence. Every release is supposed to carry a <code>scores.json.gz</code> — the raw pass/fail ledger of a public conformance suite — and the repository tracks individual gaps as markdown files in two directories, <code>issues/things-that-do-not-work/</code> and <code>issues/things-that-now-work/</code>.</p>
