Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
provenance missing-githead AI (provenance): Package has SLSA provenance attestation via Sigstore CI/CD, which provides stronger supply chain integrity than gitHead. Missing gitHead is a pipeline artifact, not a security signal for this package. ai
publish-pattern dormant-publish AI (publish-pattern): Dormancy followed by legitimate maintainer transition; SLSA provenance attestation confirms official CI/CD pipeline was used, ruling out account takeover. ai
provenance publisher-changed AI (provenance): voliva has 56 approved / 0 rejected packages and 566 days of ecosystem history; SLSA provenance confirms CI/CD publication. Legitimate team transition within polkadot-api. ai
npm-metadata no-description AI (npm-metadata): Scoped monorepo package with proper repository metadata and TypeScript exports; missing description is not a malware indicator here. ai
dependencies unvetted-dep:@polkadot-api/substrate-client AI (dependencies): Sibling package within the polkadot-api monorepo; same trusted publisher and SLSA-attested release pipeline. ai
dependencies unvetted-dep:@polkadot-api/substrate-bindings AI (dependencies): Sibling package within the polkadot-api monorepo; same trusted publisher and SLSA-attested release pipeline. ai
bogus-package bogus-package AI (bogus-package): Internal monorepo sub-package; sparse README/metadata is expected for library components not intended for standalone discovery. ai
dependencies unvetted-dep:@polkadot-api/utils AI (dependencies): Sibling package within the polkadot-api monorepo; same trusted publisher and SLSA-attested release pipeline. ai
dependencies unvetted-dep:@polkadot-api/metadata-builders AI (dependencies): Sibling package within the polkadot-api monorepo; same trusted publisher and SLSA-attested release pipeline. ai
