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
npm-metadata bundled-binaries AI (npm-metadata): re2 is a native Node.js addon; bundled .o and .node files are the expected compiled output of the RE2 C++ library and its bindings. Stable pattern for this package. ai
source-diff net-exec-file:tests/test_matchAll.js AI (source-diff): The eval() calls are heya-unit's test assertion idiom (eval(t.TEST(...))); no actual network calls exist in this test file. This is a stable false positive for this package's test suite pattern. ai
license uncommon-license:New BSD AI (license): New BSD is a well-known permissive license; the uncommon flag is a false positive for this package. ai
semgrep semgrep:child-process-import AI (semgrep): child_process is used only in a dev/CI script (create-binary-asset.js) for packaging GitHub release binaries, not in runtime or install code. Expected for a native addon package. ai
publish-pattern new-deps-added AI (publish-pattern): install-artifact-from-github is a legitimate helper for fetching prebuilt native binaries from GitHub releases; consistent with re2's documented install flow for native bindings. ai
phantom-deps phantom-dep:nan AI (phantom-deps): nan is a standard native addon build dependency referenced in binding.gyp, not a runtime import. Expected for this package. ai
phantom-deps phantom-dep:node-gyp AI (phantom-deps): node-gyp is the standard build tool for native Node.js addons; its presence as an implicit dependency is expected for re2. ai
phantom-deps phantom-dep:install-artifact-from-github AI (phantom-deps): install-artifact-from-github is the prebuilt binary fetcher used in re2's install script — expected and stable for this package. ai
install-scripts install-script:install AI (install-scripts): re2 is a native Node.js addon; its install script fetches prebuilt binaries or builds via node-gyp — the canonical pattern for native bindings, stable across all versions. ai

LOW No provenance attestation provenance

Package was published without Sigstore provenance. Only ~12% of npm packages have provenance, so this is common but not ideal.
