Accepted risks
Findings the reviewer chose to accept rather than block on.
| Source | Rule | Reason | Accepted by | When |
|---|---|---|---|---|
| dependencies | unvetted-dep:lit | AI (dependencies): lit is Google's own web components library and a natural, expected dependency for @material/web. This is stable across all versions of this package. | ai | |
| provenance | no-provenance | AI (provenance): google-wombot is a trusted Google publishing bot; absence of Sigstore provenance is not a meaningful risk signal for this well-established package. | ai |
