Kubernetes pulls the app image itself, so a k3s host is free to reap its local copy while the workload keeps running, which the `registry` plugin already does on its own. Deploys, restarts, `dokku run`, and in-cluster cron no longer assert that the image is present locally, falling back to the metadata recorded in the app's current Helm release. A `ps:restart` naming a single process type now rolls only that process type's pods rather than silently redeploying every one. Apps with an `app.json` postdeploy task still require the image locally, as that task runs on the Dokku host.
The `docker-local` scheduler supports `--sysctl` for free because docker options are passed verbatim to `docker run`, but the k3s scheduler silently dropped it. Namespaced sysctls now render into the pod's `securityContext.sysctls` for deployments, cron jobs, and one-off runs. A sysctl the kernel does not namespace fails the deploy instead of being dropped, since it cannot take effect within a pod regardless of what was requested.
