Polyfill for Metadata Reflection API
Supply chain provenance
Status for the latest visible version.
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.
| Source | Rule | Reason | Accepted by | When |
|---|---|---|---|---|
| source-diff | net-exec-file:temp/Reflect.js | AI (source-diff): temp/Reflect.js is the compiled TypeScript output of the Reflect metadata polyfill; no actual network calls or malicious code execution present. | ai | |
| provenance | no-provenance | AI (provenance): Package predates Sigstore provenance; publisher is long-established Microsoft engineer with strong track record. | ai | |
| source-diff | net-exec-file:test/Reflect.js | AI (source-diff): Core polyfill code with license URL strings and dynamic patterns; not a dropper. Standard for this metadata reflection library. | ai | |
| semgrep | semgrep:child-process-import | AI (semgrep): child_process.spawn in gulpfile.js is standard gulp build tooling, not runtime code. | ai | |
| source-diff | large-new-source-files | AI (source-diff): Build system restructuring adding tests/docs is expected for this established package. | ai |
