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 — the axios compromise (March 2026) relied on exactly this gap.

Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
source-diff obfuscated-file:dist/sources.js AI (source-diff): File contains Node.js shim source code stored as string literals for browser-side execution; long lines are expected, not obfuscation. ai
source-diff net-exec-file:dist/sources.js AI (source-diff): Network + code execution is the core feature of a browser-side Node.js sandbox; not indicative of malware. ai
provenance missing-githead AI (provenance): No material changes from prior version; likely a CI environment change, not a supply-chain indicator for this package. ai
source-diff obfuscated-file:dist/nextjs.js AI (source-diff): Bundled Next.js sandbox output; long lines are minified bundle, not obfuscation. Matches package purpose. ai
source-diff net-exec-file:dist/nextjs.js AI (source-diff): Browser sandbox intentionally combines network and dynamic execution to run user apps client-side. ai
