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. On Linux, also the cross-simulator corpus's CI tier
# (wai/quantum-cross-simulator/: the engine against pinned third-party
# simulators and integer references, each answer within its stated tolerance), its
# self-test (every injected fault caught), and its provider template held to the
# provider protocol's conformance vectors through `providers test` and `run --provider`.
# And job receipts by two verifiers (wai/quantum-conformance/receipts/):
# `verify` and receipt_verify.py, written from the provider protocol's section 8
# alone, each held to the corpus's manifest and to the other on every receipt and
# every one-member change of each valid one, and each planted defect caught.
