Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
provenance publisher-changed AI (provenance): voliva is an established publisher (70 approved/0 rejected) within the polkadot-api org; the transition from josepot is a legitimate team handoff, not a takeover. ai
publish-pattern dormant-publish AI (publish-pattern): The @polkadot-api ecosystem has 688 registry versions; dormancy in this sub-package reflects versioning cadence, not abandonment. SLSA provenance further mitigates takeover risk. ai
dependencies unvetted-dep:scale-ts AI (dependencies): scale-ts is a well-known SCALE codec library used throughout the Polkadot/Substrate JS ecosystem; stable dependency for this package. ai
dependencies unvetted-dep:@polkadot-api/utils AI (dependencies): @polkadot-api/utils is a sibling package in the same polkadot-api monorepo; expected internal dependency, not a risk. ai
bogus-package bogus-package AI (bogus-package): Monorepo sub-package; sparse README and no keywords are normal for scoped internal packages in a large monorepo. ai
npm-metadata no-description AI (npm-metadata): Scoped monorepo sub-package; missing description is a cosmetic issue, not a security signal for this well-established package. ai
