name: wai command line release

# On a tag wai-v<version> (the version wai/wai-rs/Cargo.toml states), builds the quickstart
# archive (wai/quickstart/build.sh) on each runner and attaches it to the forge release of that
# tag, each archive with its SHA-256. An archive holds bin/ (wai with the feature quickstart,
# wai-relay, wai-room, wai-remote-host, wai-pack) and share/wai/web/ (the room
# client, built once, on the macOS host, which has the WebAssembly toolchain):
#   macOS      aarch64-apple-darwin, and x86_64-apple-darwin on the Intel Mac (macos-x86_64);
#   Linux      x86_64- and aarch64-unknown-linux-musl, static, so any distribution runs it;
#   Windows    x86_64-pc-windows-msvc, as a zip.
# Each archive's own `wai` runs before it is attached (create --list, hello, verify, and on
# the hosts that run it, dev --check). A last job writes the Homebrew formula and the Scoop
# manifest for the archives attached and attaches them too; they go into the tap and the bucket
# 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 archive missing: the release lists
# what each build attached.
