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.

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
source-diff obfuscated-file:lib/gen/kinds.d.ts AI (source-diff): lib/gen/kinds.d.ts is a generated TypeScript declaration file with long union types listing AST node names — not obfuscated code. This pattern is stable for ast-types' generated type output. ai
source-diff obfuscated-file:gen/kinds.d.ts AI (source-diff): Generated TypeScript declaration file with long union type lines listing AST node kinds — not obfuscated code. This pattern is expected for auto-generated .d.ts files in AST libraries. ai
source-diff obfuscated-file:gen/nodes.d.ts AI (source-diff): Generated TypeScript declaration file with AST node interface definitions — not obfuscated code. Long lines are a natural artifact of generated TypeScript type unions. ai
npm-metadata url-dep:esprima AI (npm-metadata): esprima is an optional/dev dependency used for testing only; package has no runtime deps. The git URL points to the author's own fork, consistent with this package's long history. ai
provenance no-provenance AI (provenance): Package predates Sigstore provenance by many years; absence is expected for this vintage. ai
phantom-deps phantom-dep:esprima AI (phantom-deps): esprima is an optional test dependency, not a runtime import. Phantom detection is expected here. ai
phantom-deps phantom-dep:whiskey AI (phantom-deps): whiskey is a test runner referenced only in the test script, not a runtime import. Phantom detection is expected. ai
