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.

Accepted risks
Findings the reviewer chose to accept rather than block on.
| Source | Rule | Reason | Accepted by | When |
|---|---|---|---|---|
| dependencies | unvetted-dep:zen-observable | AI (dependencies): zen-observable is a well-known observable library used broadly in the JS ecosystem; its use in Backstage test utils is legitimate and expected. | ai | |
| dependencies | unvetted-dep:@backstage/plugin-app | AI (dependencies): @backstage/plugin-app is a first-party Backstage package in the same org scope; its use in frontend-test-utils is expected and legitimate across all versions. | ai | |
| phantom-deps | phantom-dep:@backstage/version-bridge | AI (phantom-deps): Same org scope (@backstage); phantom dep pattern is common in Backstage monorepo packages where deps are used for type resolution or transitive purposes. | ai | |
| npm-metadata | no-description | AI (npm-metadata): Monorepo package from the official Backstage project; missing description is a known pattern for internal packages in large monorepos. | ai | |
| provenance | no-provenance | AI (provenance): Backstage uses automated CI publishing; lack of Sigstore provenance is consistent across the ecosystem and not a risk indicator here. | ai | |
| phantom-deps | phantom-dep:zod | AI (phantom-deps): zod is listed as a runtime dependency in package.json; phantom-dep flag likely due to indirect usage or type-only imports in this test utility package. | ai |
