Findings the reviewer chose to accept rather than block on.
| Source | Rule | Reason | Accepted by | When |
|---|---|---|---|---|
| provenance | no-provenance | AI (provenance): pngjs predates Sigstore provenance; publisher is the original author with long history. Stable FP for this package. | ai | |
| provenance | missing-githead | AI (provenance): gitHead omission reflects newer npm CLI behavior, not a security concern for this established package/author. | ai |
