name: wai-quantum studio and desktop

# Quantum Studio (wai/quantum-studio), the interface for the browser and the
# desktop, and the desktop app around it (wai/wai-quantum-desktop):
#   - the Studio built against the engine's browser package (wai-web, feature
#     quantum_engine) and run in a browser by test/studio.test.mjs: linted, drawn and
#     planned as it is typed, run here with its receipt checked here, an error marked
#     on its line, any angle on the state vector, Ctrl+Enter, and the program and the
#     history kept across a reload; a device target's coupling map coloured by its
#     errors, a run placed and simulated on it, and the layout drawn on the map;
#     nothing scrolls sideways at a phone's width;
#   - test/hardware.test.mjs, without a browser: "Your hardware" asks the person before
#     a run that is not free, never before a free one, and sends nothing on a "no"; a job
#     in the provider's queue is asked after by its id, Cancel cancels it there, "Wait in
#     the background" leaves it, and a job left waiting gives its result when it finishes;
#   - test/service.test.mjs, without a browser: a job on the job service whose answer is
#     lost is sent again under its key to a service that keeps keys, and once, with no
#     key, to one that does not; a poll whose answer is lost does not end the wait;
#   - test/telemetry.test.mjs, without a browser: the correctness record is off by
#     default, and while off records nothing, writes nothing and asks the engine
#     nothing; and the views page agent hosts draw is built from these sources
#     (build-views.mjs --check; wai-quantum-views.yml draws it);
#   - in the browser, too: answer views drawn as an answer streams in, and the
#     correctness record turned on and its failures exported;
#   - test/locales.test.mjs, without a browser: every key of the interface's words in
#     every locale, with the same placeholders, each translation marked machine-assisted;
#   - the course in the browser, in English and in Chinese (studio.test.mjs): a lesson
#     checked by the engine, what went wrong, a hint, a pass kept in the browser, and the
#     language followed from the browser and switched;
#   - test/update.test.mjs, without a browser: the desktop app's update offer names
#     both versions, installs nothing until asked, and reports a refusal;
#   - the desktop app on macOS, Linux and Windows: its tests and clippy with warnings
#     as errors, and `check`: a job run in the app's worker process, sealed in the app
#     with a key that never leaves it, and verified, with no window. The tests hold an
#     update to the build's key and the version it was signed for, and say which
#     copies update themselves; on Linux, the release's manifests (the Homebrew cask,
#     the Scoop manifest, the update manifest) are written from releases made up here
#     (release/manifests_test.py). The installers themselves are built by
#     wai-quantum-desktop-release.yml, on a tag.
