Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
semgrep semgrep:new-function-constructor AI (semgrep): new Function() in lib/ast.js is an established internal pattern for building prototype chains in UglifyJS's AST infrastructure; input is internally generated, not user-controlled. ai
phantom-deps phantom-dep:commander AI (phantom-deps): commander is a declared runtime dependency used by the CLI bin script; the phantom-dep finding is a false positive for this CLI tool's architecture. ai
