Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
publish-pattern dormant-publish AI (publish-pattern): SLSA provenance attestation via official Facebook GitHub Actions CI mitigates account-takeover concern. ai
semgrep semgrep:dynamic-require AI (semgrep): Metro intentionally uses dynamic require() to load configurable Babel transformer paths — this is a core design feature of Metro's pluggable transform pipeline, not a security risk. ai
phantom-deps phantom-dep:flow-enums-runtime AI (phantom-deps): flow-enums-runtime is a standard Flow runtime dep in Meta OSS packages; phantom-dep flag is a false positive for this monorepo package pattern. ai
phantom-deps phantom-dep:metro-minify-terser AI (phantom-deps): metro-minify-terser is a sibling monorepo package used via config/dynamic loading; phantom-dep flag is expected for Metro's pluggable architecture. ai

HIGH Publisher changed: metro-bot → GitHub Actions (on 2026-02-27) provenance
