Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
semgrep semgrep:base64-decode AI (semgrep): Base64 decoding is used to parse inline source maps (standard spec behavior). The code context clearly shows INLINE_SOURCE_MAP_PREFIX handling — not a malicious payload. ai
publish-pattern new-deps-added AI (publish-pattern): @rollup/plugin-node-resolve is an official Rollup org package; entirely expected for a tree-shakability analysis tool. ai
