typosquat typosquat.levenshtein:cors AI (typosquat): Scoped @percy/core package; no relation to cors. Levenshtein match is a false positive. ai
install-scripts install-script:postinstall AI (install-scripts): Documented post-install script for Percy browser binary setup; stable pattern across all versions. ai
phantom-deps phantom-dep:@percy/dom AI (phantom-deps): Same-org sibling dep; phantom-dep heuristic unreliable for monorepo packages. ai
