Provenance

Supply chain provenance

Status for the latest visible version.

No SLSA provenance npm registry signatures No source commit

Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
npm-metadata suspicious-initial-version AI (npm-metadata): Publisher has strong track record; 0.0.0 reflects a scaffolded monorepo package, not throwaway malware. ai
bogus-package bogus-package AI (bogus-package): Tiny stub payload is expected for an initial placeholder release in a monorepo. ai
source-diff obfuscated-file:dist/index.js AI (source-diff): Bundled ESM output from a build tool; sample shows readable OOXML constants, not obfuscation. ai
source-diff source-size-tripled AI (source-diff): Prior version was a 22B stub; size increase reflects first real bundled build, not injected payload. ai
