Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
source-diff obfuscated-file:lib/index-ts3.7.d.ts AI (source-diff): lib/index-ts3.7.d.ts is an auto-generated TypeScript declaration file explicitly referenced in typesVersions; long lines are a known artifact of generated .d.ts files, not obfuscation. ai
maintainer-change maintainer-removed AI (maintainer-change): Maintainer transition within Babel project is consistent with known ecosystem patterns; no takeover indicators. ai
source-diff large-new-source-files AI (source-diff): @babel/types tracks JS/TS AST evolution; adding many new type/helper files across many semver versions is expected for this package. ai
source-diff obfuscated-file:lib/index-legacy.d.ts AI (source-diff): File is explicitly autogenerated TypeScript definitions (per header comment), not obfuscated code. Long lines are expected in generated type definitions. ai
provenance missing-githead AI (provenance): Large monorepo with established publisher; missing gitHead reflects CI/CD pipeline changes, not a supply chain compromise. Consistent with Babel's publish history. ai
publish-pattern new-deps-added AI (publish-pattern): New dependency is @babel/helper-validator-identifier, a sibling Babel package; legitimate refactoring. ai
maintainer-change maintainer-added AI (maintainer-change): jlhwung is an established Babel maintainer with strong track record; transition is legitimate. ai
bogus-package bogus-package AI (bogus-package): False positives for monorepo package; mass-production signal reflects Babel's structure, not spam. ai
provenance publisher-changed AI (provenance): Publisher change (jlhwung → nicolo-ribaudo) reflects legitimate Babel maintainer transition, not account compromise. ai
provenance no-provenance AI (provenance): @babel/types is a well-established core Babel package; lack of Sigstore provenance is not a risk signal here. ai
dependencies unvetted-dep:to-fast-properties AI (dependencies): to-fast-properties is a long-standing, benign dependency of @babel/types used across the Babel ecosystem; no security concern. ai
