name: wai-quantum desktop release

# On a tag wai-quantum-desktop-v<version> (the version wai/wai-quantum-desktop/Cargo.toml
# and its tauri.conf.json state), builds Quantum Studio for the desktop on each runner and
# attaches its installers to the forge release of that tag, each with its SHA-256:
#   macOS      aarch64-apple-darwin and x86_64-apple-darwin: a disk image (.dmg), with the
#              GPU state vector;
#   Linux      x86_64- and aarch64-unknown-linux-gnu: an AppImage, a Debian package and an
#              RPM package;
#   Windows    x86_64-pc-windows-msvc: an installer (-setup.exe) and a portable archive
#              (.zip) for package managers.
# Each build runs what it made before it is attached: the app's `check` (a Bell pair run in
# its worker, sealed and verified) from the bundle where the runner can run it, and its
# `update-status` (the app, the AppImage and the Debian package's app know their installer;
# the portable archive's copy knows none, so it never updates itself), the macOS app's code
# signature, the disk image's checksums, and the Debian package unpacked.
#
# Signing. Each kind is skipped, and the log says so, when its secrets are absent:
#   - Updates: with the secret WAI_QUANTUM_DESKTOP_UPDATER_KEY (and, if the key has one,
#     WAI_QUANTUM_DESKTOP_UPDATER_KEY_PASSWORD), every installer an update installs is
#     signed (the macOS app as a .app.tar.gz, the AppImage, the packages, the Windows
#     installer), and the built app's `verify-update` checks each signature with the public
#     key in tauri.conf.json, for this version, before anything is attached. Without the
#     secret the release has installers and no update: copies already installed are not
#     offered it, and update themselves no further until a release is signed.
#   - macOS: with APPLE_CERTIFICATE (a Developer ID Application certificate, .p12 in
#     base64), APPLE_CERTIFICATE_PASSWORD and APPLE_SIGNING_IDENTITY, the app is signed with
#     that identity; with APPLE_API_ISSUER, APPLE_API_KEY and APPLE_API_KEY_P8 (or APPLE_ID,
#     APPLE_PASSWORD and APPLE_TEAM_ID) it is also notarised and stapled. Without them the
#     app is signed ad hoc and not notarised, and the cask says how to open it.
#
# A last job writes the Homebrew cask and the Scoop manifest from the assets just
# attached, and, when the builds were signed for updates, the update manifest
# (latest.json), and attaches them to this version's release. The app asks the website
# for the update manifest (plugins.updater.endpoints), and the website takes it from
# this release when it is next deployed. Nothing is pushed to the tap or the bucket:
# their repositories take the cask and the manifest by hand.
#
# Uploads go to the forge directly over the private network (FORGE_API), never through
# the public tunnel. A runner that is down leaves its platform's assets missing: the
# release lists what each build attached, and the manifests leave that platform out.
