Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
provenance publisher-changed AI (provenance): Transition to GitHub Actions CI publishing with SLSA provenance; stable for this package. ai
provenance no-provenance AI (provenance): Package has no install scripts, no obfuscation, and clean content. Lack of Sigstore provenance is a low-severity hygiene issue, not a security risk for this package. ai
typosquat typosquat.levenshtein:cors AI (typosquat): Scoped package @ag-ui/core is not a typosquat of 'cors'. The Levenshtein match is a false positive due to the scoped namespace convention. Stable across all versions of this package. ai
phantom-deps phantom-dep:rxjs AI (phantom-deps): rxjs is a declared runtime dependency in package.json; the phantom-dep finding is a false positive likely due to indirect usage or re-export patterns. ai
