Clear explanation of what Cloudflare actually caches vs what people assume. In your experience, which control mattered most in production — Cache-Control/s-maxage at the origin, Cache Rules, or purge discipline after deploys? We've been building an open-source CDN control plane (CDNCA) so one console can see what each node stored; marketplace features roll out release by release. Install packages are still coming, so we point people at the site and repo README rather than paste commands here.
