Accepted risks
Findings the reviewer chose to accept rather than block on.
| Source | Rule | Reason | Accepted by | When |
|---|---|---|---|---|
| provenance | no-provenance | AI (provenance): ljharb's es-shims packages consistently lack provenance; stable false positive for this publisher/org. | ai | |
| dependencies | unvetted-dep:es-set | AI (dependencies): es-set is a sibling es-shims package by the same trusted maintainer; not a real risk. | ai |
