Remediation boundary

What RequestGuard does — and doesn't — cover

RequestGuard does not fix npm package vulnerabilities. Dependency remediation happens through package updates, patches, lockfile changes, and maintainer guidance. RequestGuard can help mitigate runtime abuse around exposed web and API flows while remediation is handled separately.
