Accepted risks
Findings the reviewer chose to accept rather than block on.
| Source | Rule | Reason | Accepted by | When |
|---|---|---|---|---|
| semgrep | semgrep:base64-decode | AI (semgrep): Decodes inline sourcemap data URLs per spec; not a malicious payload pattern. | ai | |
| phantom-deps | phantom-dep:mkdirp | AI (phantom-deps): mkdirp is listed as a runtime dependency in package.json; phantom-dep heuristic is a false positive here. | ai |
