Supply chain provenance

Status for the latest visible version.

No SLSA provenance npm registry signatures gitHead linked

Without SLSA provenance there is no cryptographic link between this tarball and the public source — the axios compromise (March 2026) relied on exactly this gap.

Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
provenance missing-githead AI (provenance): Build environment change (bun codegen) explains missing gitHead; no malicious indicators present. ai
provenance no-provenance AI (provenance): Small org package; lack of Sigstore provenance is a process gap, not a security indicator for this package. ai
npm-metadata no-description AI (npm-metadata): Scoped UI library; missing description is cosmetic, not a risk signal here. ai
provenance publisher-changed AI (provenance): Transition from human publisher to GitHub Actions CI/CD is expected for this org's monorepo workflow. ai
