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
provenance missing-githead AI (provenance): Build system changed from webpack to microbundle; missing gitHead is a side effect of the new build environment, not a supply-chain indicator. ai
provenance publisher-changed AI (provenance): Both janicklas-ralph and developit are Google contributors listed in package.json; this is a legitimate intra-team maintainer transition within GoogleChromeLabs. ai
publish-pattern new-deps-added AI (publish-pattern): postcss and css-select are established CSS ecosystem packages; their addition is consistent with critters' purpose as a CSS inlining tool and a documented migration away from the 'css' package. ai
source-diff source-size-dropped AI (source-diff): Size drop from 1MB to 202KB is explained by switching from webpack bundling (which inlined deps) to microbundle (which keeps deps external). Not a stub/redirect. ai
bogus-package bogus-package AI (bogus-package): critters is a legitimate package by developit; v0.0.1 is an early placeholder release — sparse metadata is expected at initial publish and does not indicate spam or malice. ai
npm-metadata no-description AI (npm-metadata): Missing description in v0.0.1 is consistent with an initial placeholder release by a well-known publisher; not a spam indicator for this package. ai
