Provenance

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 publisher-changed AI (provenance): Publisher change from mitchellhamilton to emotion-release-bot is a documented, legitimate transition to a release bot for the emotion-js project. Stable for all future versions. ai
maintainer-change maintainer-added AI (maintainer-change): emotion-release-bot is the official release automation account for the emotion-js project; its addition as maintainer is a legitimate organizational change, not a compromise. ai
provenance missing-githead AI (provenance): Established emotion-js package with trusted publisher; missing gitHead reflects a tooling/environment change, not a supply chain concern. ai
provenance no-provenance AI (provenance): Trusted long-standing publisher (mitchellhamilton) with 1271 approved packages; lack of Sigstore attestation is not a disqualifier for this package. ai
