Accepted risks
Findings the reviewer chose to accept rather than block on.
| Source | Rule | Reason | Accepted by | When |
|---|---|---|---|---|
| semgrep | semgrep:dynamic-require | AI (semgrep): Core worker-module loading mechanism; user supplies the module path, not attacker-controlled in this context. | ai | |
| semgrep | semgrep:base64-decode | AI (semgrep): Base64 decoding is used to handle data: URI worker scripts in Node.js — standard behavior for a Web Worker polyfill. Not a malicious payload indicator. | ai |

provenance
Package was published without Sigstore provenance. Only ~12% of npm packages have provenance, so this is common but not ideal.
