proton_cefsetup installs the immutable CEF runtime required by a specificProton release. Runtime installations are shared by all projects for a user andare selected by platform, archive digest, and layout version.
Install the selected runtime with:
moonx moonbit-community/proton_cefsetup
Proton's developer tools and bundler use the module's store package to resolveand validate the installation without persisting project-local absolute paths.The package exposes default-runtime operations for direct use and declared-runtime operations for tooling that must follow an application's resolvedProton dependency. Both return the resolved SDK, runtime, platform, and archivepaths. Installation uses one lock and one staging directory before atomicallypublishing a manifest-backed runtime.
