No build attestation or trusted-publisher provenance was found. This reduces publication transparency, but it is not by itself evidence that the release is unsafe.
The repository is owned by an individual account rather than an organization, so the concentrated recent contribution base is not visibly offset by organizational backing.
All 18 recent commits came from one contributor, so maintenance capacity is concentrated and could be vulnerable if that contributor becomes unavailable.
The project uses TypeScript, Rollup, Babel, and npm scripts for its build, showing established build tooling. No security scanning tools were detected, which is a modest transparency gap.
The repository has no security policy, leaving vulnerability-reporting and response expectations undocumented.
