No SLSA provenance npm registry signatures No source commit

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
install-scripts install-script:preinstall AI (install-scripts): Long-standing preinstall for global-install detection; canonical Yarn package. ai
semgrep semgrep:child-process-import AI (semgrep): child_process used in preinstall.js for global install setup; expected for a package manager. ai
bogus-package bogus-package AI (bogus-package): Yarn is a bundled package manager; no-deps/no-keywords/inflated-semver signals are all false positives. ai
typosquat typosquat.levenshtein:yargs AI (typosquat): yarn is the canonical package manager, not a typosquat of yargs. ai
semgrep semgrep:dynamic-require AI (semgrep): Loads v8-compile-cache from a fixed relative path; not arbitrary. ai

HIGH Package has 'preinstall' script install-scripts

Script: :; (node ./preinstall.js > /dev/null 2>&1 || true)

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.
