wai/wai-quantum-js/ packs the job service's engine for WebAssembly (wai-web with its quantum_engine feature, the engine of wai-quantum 0.7.0) and its bindings as an ES module with its TypeScript declarations and no dependencies, for a page (init() fetches the .wasm beside the module) or for Node (init is given its bytes). The package keeps its own version line, as the Python package does. - build.sh: wai-web built for wasm32 with paths remapped (as the views build does), wasm-bindgen 0.2.127 (refused if it is not the version wai-web's lock file pins), package.json, README and the licence copied, the build refused if a local path is left in the bindings or the binary, then packed. - test/smoke.mjs, on the package unpacked: a job run with a fresh 32-byte key and its receipt verified with this engine's did:key; a forged result that does not verify; a program linted and drawn; a refused program with its diagnostic code (Q310). - test/install.mjs: the README's Node example, run in an empty app that installed the tarball with npm, the package found by name and its .wasm by the subpath it exports. - ci/check.sh runs them all and holds the tarball to the package's allow-list (the seven files and nothing else). - wai-quantum-js.yml runs ci/check.sh on Linux. wai-quantum-js-release.yml runs it on a wai-quantum-cli-v* tag and attaches the tarball and its SHA-256 to the release. Nothing is published to a registry from CI. On the M3 Ultra: the .wasm is 5,928,153 bytes, the tarball 2.26 MB, and every check passes. Co-Authored-By: Claude Opus 5.5 <[email protected]>
