A new crate, wai-quantum-cli, whose binary is wai-quantum. It depends on the wai-quantum library alone, so `cargo install wai-quantum-cli` can install it. - run: an OpenQASM program planned and run as the service runs it (wai_quantum::engine), signed with this user's key; --json prints the job as the service returns it. Shots, seed, method, observables, amplitudes, noise and method options; an unknown flag or noise channel is an error. - plan, lint (the line of the first problem), draw (the circuit as text, gates packed into columns, conditions in a legend). - submit: the same job on the service (feature `service`, on by default), waiting for a long one. - verify: a job's receipt from run, submit or the service, and every receipt the research tools sign; a changed result is INVALID. - key: this user's did:key; --key FILE and --demo-key as before. - methods: each method's reach in a job's memory here. - mcp: run, plan, lint, draw, verify and the method list for an agent, over stdio; runs stay on this machine. - lab: the earlier wai-quantum command, moved here from wai-rs unchanged (wai:: paths now wai_quantum::), its key handling shared with run. - completions for bash, zsh, fish, elvish and PowerShell. - Feature `metal`: the GPU state vector on macOS. With no default features it builds for wasm32-wasip2. wai-rs loses the wai-quantum bin and its cli_keys feature. The wai README's quickstart now uses the new crate. smoke.sh exercises every command, and .github/workflows/wai-quantum-cli.yml runs the tests, clippy with and without submit, smoke.sh, and the WASI component against the native build, byte for byte; on macOS also a run on the GPU.

wai-quantum engine: one receipt form for every host; an unknown noise channel refused; did_key
- engine::receipt is the service's receipt form, moved: a result sealed over the request and the result in their RFC 8785 canonical text, and checked. The service keeps its key file and seals with it; the command line seals with the user's key in the same form, and one verify checks both. The first receipts' form still verifies. - A job's noise naming a channel the model does not know is refused with the channels it knows (catalog::NOISE_CHANNELS). It was read as no noise, so a misspelt channel ran the circuit noiseless. - quantum_receipt::did_key: an Ed25519 key's did:key, held to the W3C method's example, for signers that depend on the library alone.

wai-quantum: the job service's engine in the library (feature quantum_engine)
The service's planner (catalog), runner (run) and dynamic-circuit walk (dynamic) move unchanged into wai_quantum::engine, so every host that runs a job plans and answers it as the service does. The service keeps what is its own: HTTP, the job queue and its limits, energy metering, its signed receipts, MCP and its examples. - The GPU state vector is behind quantum_sv_metal: without it, the plan says the build has none, and the build still compiles for any target. - The feature reads JSON numbers correctly rounded (serde_json/float_roundtrip), as the service always has. - The test of the service's own examples stays with the service; the Grover test, which builds its program with the toolchain, runs where quantum_toolchain is on.

wai-quantum CLI and IDE: a receipt names its signer by its key's did:key
The CLI signed every receipt as "did🔑wai-quantum-cli" and the IDE as "did🔑quantum-ide", labels that name no key. Now that each signs with its own key, the receipt's signer_id is that key's Ed25519 did:key (wai::signer_id::did_key), so a verifier reads the signer from the id as jwp-receipts §7.1 describes. The IDE binding gains signer_did() for the page to show it. Co-Authored-By: Claude Opus 5.5 <[email protected]>
wai-quantum: one OpenQASM reader for the service, the CLI and the browser IDE; receipts signed with the signer's own key
The OpenQASM reader moves from the service into the library as wai_quantum::qasm (feature quantum_qasm). The service, `wai-quantum run --qasm` and the browser IDE's import now read a program the same way and refuse the same programs: two registers, broadcast gates and comments read as the service reads them, where the IDE's line reader dropped what it did not know. - qasm::dyadic_circuit takes a program whose measurements all come at the end, and refuses one that measures and then acts, with the reason. - quantum_toolchain::from_qasm, the older line reader, refuses what it cannot take (more than one register, reset, gate definitions, if/while/for, a gate after a measurement, two statements on one line) and names the full reader, instead of dropping the line. - wai-web: the IDE binding builds its JSON with serde_json, so a quote or a control character in a program or an error no longer breaks the reply. set_signing_key, public_key_hex and key_is_demo let a page sign receipts with its own key; without one it signs with the published demo key and says so. - The CLI signs with --key FILE, $WAI_QUANTUM_KEY, or this user's key at $XDG_CONFIG_HOME/wai/quantum-key (~/.config/wai/quantum-key), made from the operating system's random source with mode 0600 on first use. --demo-key keeps the published key, with a note that such a receipt shows the result is unaltered, not who signed it.
