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 |
|---|---|---|---|---|
| npm-metadata | no-description | AI (npm-metadata): Monorepo package with clear role metadata and repository context; missing description is benign for this package type. | ai | |
| provenance | no-provenance | AI (provenance): Provenance is not yet standard practice; absence is not a security signal for established packages with strong ecosystem trust. | ai | |
| dependencies | unvetted-dep:@backstage/version-bridge | AI (dependencies): Same-org @backstage/* dependency from the official Backstage monorepo; expected and legitimate for this package. | ai | |
| dependencies | unvetted-dep:@backstage/core-plugin-api | AI (dependencies): Same-org @backstage/* dependency from the official Backstage monorepo; expected and legitimate for this package. | ai | |
| dependencies | unvetted-dep:@backstage/plugin-app-react | AI (dependencies): Same-org @backstage/* dependency from the official Backstage monorepo; expected and legitimate for this package. | ai | |
| dependencies | unvetted-dep:@backstage/filter-predicates | AI (dependencies): Same-org @backstage/* dependency from the official Backstage monorepo; expected and legitimate for this package. | ai | |

| phantom-deps | phantom-dep:zod | AI (phantom-deps): zod is listed as a runtime dependency with a broad version range (v3/v4); phantom detection likely reflects conditional/indirect usage patterns in this Backstage package. | ai | |
| phantom-deps | phantom-dep:@backstage/types | AI (phantom-deps): Same-org @backstage/* package; phantom detection is expected for type-only or indirect usage in the Backstage monorepo ecosystem. | ai | |
| phantom-deps | phantom-dep:@backstage/filter-predicates | AI (phantom-deps): Same-org @backstage/* package; phantom detection is expected for indirect usage patterns in the Backstage monorepo ecosystem. | ai | |
| dependencies | unvetted-dep:@backstage/frontend-plugin-api | AI (dependencies): Same-org @backstage/* dependency from the official Backstage monorepo; expected and legitimate for this package. | ai | |
