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 publisher-changed AI (provenance): Maintainer transition from hardmath123 to tjvr occurred in 2018; well-documented and stable for 6+ years. ai
publish-pattern new-deps-added AI (publish-pattern): New deps (moo, commander, semver, railroad-diagrams) are all established utilities; legitimate feature expansion, not malicious injection. ai
source-diff source-size-dropped AI (source-diff): Size drop reflects removal of nomnom and refactoring to commander; normal maintenance, not code replacement with stub. ai
dependencies unvetted-dep:moo AI (dependencies): moo is a standard lexer library; natural dependency for a parser generator. Established package with clear purpose. ai
npm-metadata url-dep:railroad-diagrams AI (npm-metadata): railroad-diagrams is an optional dependency pinned to a specific immutable git commit hash, used only for diagram generation. The immutable pin mitigates the swap risk; this is stable for this package. ai
maintainer-change maintainer-added AI (maintainer-change): tjvr is a visible contributor to nearley's GitHub repo; legitimate maintainer addition, not account compromise. ai
dependencies unvetted-dep:nomnom AI (dependencies): nomnom is a stable, widely-used CLI argument parser; constraint ~1.6.2 is appropriate for this package. ai
provenance no-provenance AI (provenance): nearley predates Sigstore provenance; absence is expected for packages of this age and does not indicate risk. ai
semgrep semgrep:dynamic-require AI (semgrep): Dynamic require loads user-provided grammar files in test tool; intended use case for parser generator, not arbitrary module loading. ai
