Supply chain provenance
Status for the latest visible version.
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.
| Source | Rule | Reason | Accepted by | When |
|---|---|---|---|---|
| provenance | missing-githead | AI (provenance): Absence of gitHead is a minor publish-environment difference, not a security signal. Publisher trysound is a listed contributor with a strong track record. | ai | |
| provenance | publisher-changed | AI (provenance): Publisher change from stevenvachon to jonschlinkert occurred in 2015 (~10 years ago). Package.json, repo URL, and author field all consistently reflect jonschlinkert. Long-resolved historical transition, not a risk. | ai | |
| provenance | no-provenance | AI (provenance): Package predates Sigstore provenance attestation by many years; absence is expected and not a risk signal for this package. | ai |
