| dependencies | unvetted-dep:which-builtin-type | AI (dependencies): which-builtin-type is a well-known es-shims ecosystem package maintained by ljharb; its use here is expected and benign. | ai | |
| provenance | no-provenance | AI (provenance): ljharb's packages consistently lack Sigstore provenance; this is a known pattern for this publisher and not a risk indicator. | ai |
