Provenance

Supply chain provenance

Status for the latest visible version.

Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
provenance missing-githead AI (provenance): Single version anomaly; no other risk signals present. Likely a one-off local publish rather than a supply chain concern. ai
install-scripts install-script:postinstall AI (install-scripts): Postinstall only prints a welcome message; no network access or arbitrary code execution. ai
