Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
source-diff obfuscated-file:dist/index.d.cts AI (source-diff): Generated .d.cts type declarations (tsdown --dts); long lines are union types, not obfuscation. ai
provenance publisher-changed AI (provenance): Legit manual→CI/CD transition with SLSA attestation on canonical Resend SDK. ai
provenance missing-githead AI (provenance): Expected side-effect of moving to CI/CD attested publish. ai
dependencies unvetted-dep:svix AI (dependencies): svix is a well-known webhook verification SDK; its use in resend is expected and legitimate. ai

v6.18.0

2 findings
INFO Has SLSA provenance attestation provenance

Published via CI/CD with Sigstore attestation (predicate: https://slsa.dev/provenance/v1). This is the strongest supply chain integrity signal.
