No SLSA provenance npm registry signatures No source commit

Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
provenance missing-githead AI (provenance): Package is 2748 days old with 28 versions, same publisher throughout. Missing gitHead is a metadata quality issue, not a security signal for this established package. ai
provenance no-provenance AI (provenance): Package predates Sigstore provenance by years; absence is expected for this long-established package. ai
phantom-deps phantom-dep:app-root-path AI (phantom-deps): Likely used via config convention rather than direct import; no security implication for this utility package. ai
phantom-deps phantom-dep:@babel/polyfill AI (phantom-deps): Framework-scoped polyfill loaded by convention at runtime; not a security concern. ai
