Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
publish-pattern rapid-publish AI (publish-pattern): Package has 20 versions in 46 days; rapid iteration is the established pattern for this package. ai
install-scripts install-script:postinstall AI (install-scripts): Runs a bundled local script (copy-supabase-assets.js) to copy migration assets; no network fetch or arbitrary code execution. ai
phantom-deps phantom-dep:pdf-parse AI (phantom-deps): LangChain document loaders use optional/dynamic imports; declared dep is legitimately used at runtime. ai
phantom-deps phantom-dep:officeparser AI (phantom-deps): Same pattern as pdf-parse; optional document loader dependency. ai
phantom-deps phantom-dep:srt-parser-2 AI (phantom-deps): Same pattern; optional document loader dependency for SRT files. ai
