Accepted risks
Findings the reviewer chose to accept rather than block on.
| Source | Rule | Reason | Accepted by | When |
|---|---|---|---|---|
| semgrep | semgrep:env-spread | AI (semgrep): env-spread is in test harness setting NODE_PATH for spawned launcher; no exfil destination. | ai | |
| semgrep | semgrep:dynamic-require | AI (semgrep): Fires in test files using a constant path variable; stable false positive for this package. | ai | |
| provenance | missing-githead | AI (provenance): SLSA provenance attestation present; missing gitHead is a minor metadata gap, not a security signal. | ai | |
| source-diff | source-size-tripled | AI (source-diff): Size increase is a new .d.ts type declaration file (80KB), not executable payload. | ai | |
| install-scripts | install-script:postinstall | AI (install-scripts): Standard prebuilt-binary selection for Rust-native CLI; platform packages are scoped under @fallow-cli/* as optional deps. | ai |
