Provenance

Supply chain provenance

Status for the latest visible version.

No SLSA provenance npm registry signatures gitHead linked

Without SLSA provenance there is no cryptographic link between this tarball and the public source, so a manually published version cannot be tied back to a reviewed commit.

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.

INFO Missing gitHead — previous versions had it provenance

[Accepted risk] This version has no gitHead field linking it to a source commit, but previous versions did. This suggests the publish environment changed. Published by: GitHub Actions.

v6.17.2
