Provenance

Supply chain provenance

Status for the latest visible version.

No SLSA provenance npm registry signatures gitHead linked

Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
semgrep semgrep:new-function-constructor AI (semgrep): Fires inside webpack-bundled compare output; standard bundler pattern, not user-controlled input. ai
semgrep semgrep:dynamic-require AI (semgrep): Command plugin loader pattern; loads from __dirname subdirectories, not arbitrary user input. ai
semgrep semgrep:shady-links-raw-ip AI (semgrep): Hardcoded 127.0.0.1 for local report server; intentional localhost-only design. ai
semgrep semgrep:child-process-import AI (semgrep): Used for remote browser/server management; core feature of a visual regression testing tool. ai
phantom-deps phantom-dep:diverged AI (phantom-deps): diverged is referenced in build scripts (build-compare copies it); not a phantom dep in practice. ai

LOW No provenance attestation provenance

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