Provenance

Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
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
