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 |
|---|---|---|---|---|
| semgrep | semgrep:dynamic-require | AI (semgrep): BackstopJS loads config files dynamically by design; stable pattern across all versions. | ai | |
| semgrep | semgrep:child-process-import | AI (semgrep): BackstopJS spawns CasperJS/SlimerJS as child processes — core functionality, not malicious. | ai | |
| phantom-deps | phantom-dep:casperjs | AI (phantom-deps): casperjs is invoked via child_process spawn, not require(); phantom-dep is a false positive here. | ai | |
| phantom-deps | phantom-dep:slimerjs | AI (phantom-deps): slimerjs is similarly invoked as an executable, not imported; false positive. | ai |

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