declare the PolyForm license in every manifest The crates read as unlicensed to every tool that looks: license-file is never inherited by workspace members, so [workspace.package] license-file = "LICENSE" covered nothing and all six came back with no license at all in a cargo-deny sweep. PolyForm is not on the SPDX list, so it is written as a LicenseRef, which is valid expression syntax and stays machine-checkable instead of hiding behind a file no tool inherits. The LICENSE file is unchanged.
