Both were measured, not theorised. `pm uninstall --user 0 com.celzero.bravedns` succeeded while the VPN was pinned and DISALLOW_CONFIG_VPN was set -- I ran it to check whether the provider was protected, and it removed the app, took the DNS filter with it, and left the always-on pin aimed at a package that no longer existed. The second hole was quieter: without lockdown, stopping the tunnel let traffic flow normally, so the filter only held while it was running. So the provider now gets setUninstallBlocked, re-asserted every pass, and the pin runs with lockdown. Lockdown is a real hazard and is deliberate: if the VPN app breaks, the device has no connectivity until ownership is released. That is only survivable because the release path lives in the enforcer app and needs no network. releaseDeviceOwner reads the pinned package before unpinning it, then unblocks its uninstall. Reversed, getAlwaysOnVpnPackage returns null after the unpin and the provider would stay unremovable forever -- the same trap the self-uninstall ordering already avoids. Home coordinates are provisioned. The pass now logs "applied AT_HOME" rather than LOCATION_UNKNOWN, so enforcement is finally geofenced rather than permanent-everywhere, driven by a real fix. `pm uninstall --user 0` on the provider now returns DELETE_FAILED_OWNER_BLOCKED. What this does NOT fix: RethinkDNS's blocklists are gone with the uninstall, since they live in app-private storage. The filter is running with no rules and youtube.com resolves normally until they are re-entered. And nothing here stops those rules being switched off from inside the app -- no device owner API can.
