name: wai-quantum service

# The WAI quantum stack as a public job service (wai/wai-quantum-service): its
# tests, clippy with warnings as errors, and its smoke checks over HTTP against
# an instance started here, on Linux and on the macOS runner (the host the
# service is deployed to). Its tests also hold the command line's snapshot of
# its MCP tools (wai/wai-quantum-cli/docs/service-mcp.json) to the live list,
# and one (tests/restart.rs) kills the service mid-job and starts it again on
# its store. Each instance here keeps its job store in the runner's own
# scratch directory.
