Accepted risks
Findings the reviewer chose to accept rather than block on.
| Source | Rule | Reason | Accepted by | When |
|---|---|---|---|---|
| dependencies | unvetted-dep:gopd | AI (dependencies): gopd is a well-known es-shims utility maintained by ljharb; legitimate dependency for this polyfill package. | ai | |
| dependencies | unvetted-dep:define-properties | AI (dependencies): define-properties is a core es-shims utility maintained by ljharb; legitimate and expected dependency. | ai | |
| dependencies | unvetted-dep:iterator.prototype | AI (dependencies): iterator.prototype is part of the es-shims ecosystem maintained by ljharb; directly relevant to this iterator helpers polyfill. | ai | |
| phantom-deps | phantom-dep:has-symbols | AI (phantom-deps): has-symbols referenced in config/test files is a standard es-shims pattern; not a security concern for this package. | ai | |
| provenance | no-provenance | AI (provenance): ljharb is a highly trusted publisher with a decade-long track record; absence of provenance attestation is not a risk signal here. | ai |
