A new crate, wai/wai-quantum-py, built by maturin 1.15.0 into one abi3 wheel per platform (pyo3 0.29.3, Python 3.9 on), module wai_quantum. Its extension module wraps the shared job engine and nothing else: run, plan, lint, draw (text and the engine SVG), layout, critique, improve, shortcuts, equivalent, verify, seal, canonical, digest, methods, accuracy_classes and history, values crossing one to one with JSON (NaN, integers past 64 bits and non-string keys refused). A job is the service form as a plain dict with helpers (counts, probabilities, expectations, amplitudes, method, accuracy, receipt); Key reads and writes the command line key files and finds the same user key; bloch gives each qubit reduced state from the engine expectation values. A refusal raises EngineError with the engine message, its line, and a code slot for the engine diagnostic codes. Service is a client in the standard library alone for the job service (submit, status, result, cancel, run), naming itself wai-quantum-python/<version>, its receipts checked here offline. Widgets (the widgets extra): Circuit (the engine drawing, gates clickable, authorship marks from a history), Result, Receipt (the engine verdict) and Bloch (drag to turn), each a plain ES module, each with static HTML (and SVG) fallbacks that render without the widget library. Five doc notebooks run in CI and are held to their stored outputs. ci/check.sh is the whole check; 62 pytest tests hold the package to the command line (same results, plans, lints, critiques, drawings, methods, equivalence verdicts; receipts verified both ways; the same user key; the digest recomputed from Python canonical bytes), to the service run locally, and run the front ends under node on the payloads; Python 3.9 smoke with the wheel alone. Workflow wai-quantum-py.yml runs it on linux and macos. Co-Authored-By: Claude Opus 5.5 <[email protected]>
