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
dependencies unvetted-dep:@lezer/lr AI (dependencies): @lezer/lr is a first-party Lezer ecosystem package by the same author (Marijn Haverbeke); not a third-party risk for this package. ai
source-diff obfuscated-file:dist/index.js AI (source-diff): dist/index.js is a lezer-generator output file — generated parser tables with long lines are expected and documented in the build script. Not obfuscation. ai
publish-pattern new-deps-added AI (publish-pattern): @lezer/common is a first-party dependency from the same org/maintainer; adding it is benign for this package. ai
bogus-package bogus-package AI (bogus-package): Lezer ecosystem package by Marijn Haverbeke; inflated semver reflects prior development history, not spam. Short README and no keywords are quality issues only. ai
phantom-deps phantom-dep:@lezer/common AI (phantom-deps): @lezer/common is a legitimate peer/runtime dep in the same org scope; phantom detection is a false positive for this package. ai
