phantom-deps phantom-dep:@babel/core AI (phantom-deps): Framework-scoped dep loaded by convention in Metro's transform pipeline. ai
phantom-deps phantom-dep:metro-transform-worker AI (phantom-deps): Sibling monorepo package loaded dynamically by worker path; stable false positive. ai
phantom-deps phantom-dep:metro-babel-transformer AI (phantom-deps): Sibling monorepo package loaded by convention; stable false positive. ai
phantom-deps phantom-dep:source-map AI (phantom-deps): source-map is a declared runtime dep used transitively via config; stable false positive for this package. ai
semgrep semgrep:env-spread AI (semgrep): Passing process.env to jest-worker child processes is standard build-tool behavior for Metro. ai
phantom-deps phantom-dep:hermes-parser AI (phantom-deps): hermes-parser is a declared runtime dep used via config/plugin loading; stable false positive for this package. ai
semgrep semgrep:dynamic-require AI (semgrep): Loads user-configured asset plugins by design; documented extension point in Metro. ai
semgrep semgrep:hex-decode AI (semgrep): Buffer.from(sha1, 'hex') constructs a cache key from a SHA1 hash — not a malicious payload. ai
