// and no other properties are added to globalThis by undici.install(). const proxyGlobalThis =likely benign Test-only Proxy around globalThis that checks no unexpected globals are set by undici.install().Reasoning
The Proxy wraps globalThis in a test verifying that undici.install() does not add unexpected globals. It is a test-harness assertion on the set trap, not a malicious interposition on production code. Test-file context makes it benign, though the pattern is inherently powerful, so confidence is not maximal.
