Accepted risks
Findings the reviewer chose to accept rather than block on.
| Source | Rule | Reason | Accepted by | When |
|---|---|---|---|---|
| dependencies | unvetted-dep:iobuffer | AI (dependencies): iobuffer is a legitimate buffer utility from the same image-js/cheminfo ecosystem; its use in a PNG codec is expected and benign. | ai | |
| provenance | no-provenance | AI (provenance): Established package with 29 versions and a strong publisher track record; lack of provenance attestation is common and not a meaningful risk signal here. | ai |

Package was published without Sigstore provenance. Only ~12% of npm packages have provenance, so this is common but not ideal.
