Accepted risks
Findings the reviewer chose to accept rather than block on.
| Source | Rule | Reason | Accepted by | When |
|---|---|---|---|---|
| source-diff | obfuscated-file:coverage/prettify.js | AI (source-diff): coverage/prettify.js is the standard Google Code Prettify syntax highlighter included in nyc/Istanbul HTML coverage reports — a well-known minified library, not malicious code. | ai | |
| semgrep | semgrep:new-function-constructor | AI (semgrep): new Function('return this;') is a standard polyfill pattern for obtaining the global object in strict mode; intentional and safe in this ES6 shim context. | ai |
