name: wai-quantum command line

# The wai-quantum command line (wai/wai-quantum-cli): its tests and clippy with
# warnings as errors, with and without `submit`; its smoke checks (smoke.sh: lint,
# plan, run, verify and a forged result refused, key, draw, MCP over stdio, the
# research tools); and the WASI component, whose output under wasmtime equals the
# native build's byte for byte. On macOS, also with the GPU state vector. Its tests
# include the model harness (src/eval.rs): every task's reference solved and an
# empty program not, a scripted run, a model server on this machine asked and one
# elsewhere refused, and the corpus (wai/quantum-conformance/eval/) held to the
# task set.
