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.

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
source-diff obfuscated-file:cjs/xxhash-wasm.js AI (source-diff): The 'obfuscated' long line is a WebAssembly binary inlined as a Uint8Array of numeric bytes — the expected and documented output of the wat2wasm build step for this WASM hashing library. ai
source-diff obfuscated-file:cjs/xxhash-wasm.cjs AI (source-diff): The long line is a WebAssembly binary inlined as a Uint8Array — standard pattern for wasm-in-JS packages. Not obfuscation; consistent with the package's documented purpose and build pipeline. ai
