On 2026-10-09 the control node's route-proxy failed every lookup against 10.10.0.1 alone for twenty
minutes while the machine's file listed both mesh resolvers; its copy lives under the runtime's
root-only directory and no tool read it. docker_resolv_conf reads /etc/resolv.conf as the container
sees it through the runtime's archive (docker cp, no exec), parses it, and says whether it lists the
same resolvers as the machine.
