Accepted risks
Findings the reviewer chose to accept rather than block on.
| Source | Rule | Reason | Accepted by | When |
|---|---|---|---|---|
| provenance | publisher-changed | AI (provenance): CI/CD-attested publish, improved provenance vs prior manual publish. | ai | |
| maintainer-change | maintainer-added | AI (maintainer-change): Consistent with org-managed CI transition, no behavior change in diff. | ai | |
| maintainer-change | maintainer-removed | AI (maintainer-change): Paired with added maintainer under same CI transition, no malicious indicators. | ai | |
| semgrep | semgrep:base64-decode | AI (semgrep): Base64 decoding is used to deserialize UCAN delegation tokens — core functionality of this library, not a payload-hiding pattern. | ai | |
| phantom-deps | phantom-dep:@ucanto/transport | AI (phantom-deps): @ucanto/transport is a declared runtime dep used transitively; phantom-dep heuristic is a false positive here. | ai |
