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
dependencies unvetted-dep:@isaacs/cliui AI (dependencies): @isaacs/cliui is a known isaacs-authored CLI UI library, a stable dependency of jackspeak across multiple versions; not a risk for this package. ai
source-diff source-size-tripled AI (source-diff): Size increase explained by TypeScript migration to dual CJS/ESM build with source maps; no injected payload indicators. ai
dependencies unvetted-dep:@pkgjs/parseargs AI (dependencies): @pkgjs/parseargs is the Node.js Package Maintenance WG's official arg parser, listed as optional dep; low risk for this package. ai
bogus-package bogus-package AI (bogus-package): isaacs is Isaac Z. Schlueter, npm's creator. The spam-publisher flag is a false positive for this high-profile, long-standing maintainer. ai
provenance no-provenance AI (provenance): Published by isaacs (Isaac Z. Schlueter), a highly trusted npm ecosystem maintainer. Lack of provenance is not a meaningful risk signal for this publisher. ai
