examples/conformance_server.exs is the package-owned authenticated Bandit
fixture used by the frozen official server runner and exact official client
smoke gates. It mints a short-lived credential only inside the development/test
fixture; the production authentication boundary is unchanged.
See the root CONFORMANCE.md for the exact runner version,
commit, archive digest, commands, observed scored and not-scored results,
expected-failure status, client versions, and non-certification statement.
