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
provenance missing-githead AI (provenance): Established package with trusted publisher track record; missing gitHead reflects a publish environment change but no other risk signals are present. ai
provenance no-provenance AI (provenance): Package predates Sigstore provenance; absence of attestation is expected for this maintainer's workflow and not a risk indicator given clean history. ai
publish-pattern new-deps-added AI (publish-pattern): ua-parser-js is a well-known UA parsing library and a natural replacement for the removed 'useragent' dep in this UA-matching utility. Not a suspicious injection. ai
