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 |
|---|---|---|---|---|
| provenance | missing-githead | AI (provenance): Babel monorepo packages commonly lack gitHead after CI/CD tooling changes; not a security signal for this well-established official package. | ai | |
| provenance | no-provenance | AI (provenance): Babel packages published before Sigstore provenance adoption; absence of attestation is expected for this era of releases. | ai | |
| provenance | publisher-changed | AI (provenance): nicolo-ribaudo is a well-known Babel core contributor; the hzoo→nicolo-ribaudo transition is a legitimate Babel team maintainer change, not a compromise. | ai | |
| bogus-package | bogus-package | AI (bogus-package): hzoo, loganfsmyth, danez are legitimate Babel team members; mass-production flag reflects normal Babel plugin ecosystem; tiny payload is expected for a focused Babel transform plugin. | ai | |
| maintainer-change | maintainer-added | AI (maintainer-change): nicolo-ribaudo is a recognized Babel core contributor with a strong track record; addition is a legitimate team roster change. | ai | |
| maintainer-change | maintainer-removed | AI (maintainer-change): xtuc removal is consistent with normal Babel team roster changes; no evidence of malicious takeover. | ai |
