Provenance

Supply chain provenance

Status for the latest visible version.

No SLSA provenance npm registry signatures No source commit

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
install-scripts install-script:install AI (install-scripts): The install script runs 'make commonjs', a local build step to compile CommonJS output. No network access or arbitrary code execution; stable pattern for this package across versions. ai
provenance no-provenance AI (provenance): Mature package (5224 days old) with strong publisher track record; lack of provenance is expected for older packages and not a meaningful risk signal here. ai
email-domain unclaimed-email:jjmadkisson at gmail dot com AI (email-domain): Gmail.com is a Google-hosted domain and cannot be hijacked. This is a false positive — the rule appears to have misidentified the gmail.com domain as unclaimed. ai
publish-pattern dormant-publish AI (publish-pattern): Version diff shows no material changes; dormancy followed by a clean maintenance release on a 14-year-old package with strong publisher history is not indicative of takeover. ai
