SourceRuleReasonAccepted byWhen
provenance publisher-changed AI (provenance): Migrated to GitHub Actions CI/CD publishing with SLSA provenance; standard for webpack org packages. ai
source-diff source-size-tripled AI (source-diff): Dual CJS/ESM build + bundled TypeScript types explains the size increase. ai
phantom-deps phantom-dep:@types/less AI (phantom-deps): @types/less provides ambient types for the less peer dep; not directly imported by design. ai
