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 no-provenance AI (provenance): sindresorhus packages predate widespread Sigstore adoption; absence of provenance is expected and not a risk signal for this well-established publisher. ai
dependencies unvetted-dep:duplexer AI (dependencies): duplexer is a long-standing, well-known stream utility; its use in a gzip streaming package is entirely appropriate and poses no security concern. ai
