Accepted risks
Findings the reviewer chose to accept rather than block on.
| Source | Rule | Reason | Accepted by | When |
|---|---|---|---|---|
| dependencies | unvetted-dep:number-is-nan | AI (dependencies): number-is-nan is a trivial NaN-check polyfill by sindresorhus, stable and benign. Acceptable for this package across all versions. | ai | |
| provenance | no-provenance | AI (provenance): Package is ~10 years old, predating Sigstore provenance. Absence is expected and not a risk signal for this well-established package. | ai |
