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
bogus-package bogus-package AI (bogus-package): Package is ~10 years old with 3 approved dependents and a clean publisher history. Sparse metadata reflects era conventions, not malicious intent. ai
npm-metadata no-description AI (npm-metadata): Old package with no description; consistent with era and publisher history. Not a security signal for this package. ai
semgrep semgrep:eval-usage AI (semgrep): eval() in assets/json2.js is the canonical JSON2 polyfill pattern — a well-known legacy library, not a supply-chain risk. Stable for this package. ai
semgrep semgrep:dynamic-require AI (semgrep): Dynamic require in tools/generate-test-fixture.js loads the local esprima module by path for test tooling — expected dev-tool pattern, not a risk. ai
