The five DinD lab nodes run privileged with cgroupns=host, a writable host cgroupfs and seccomp/apparmor off, and carried no resource limit of any kind. A runaway node therefore competes with the Actions runner agent itself, and the platform reports that only as 'lost communication', never as an OOM. Only pids_limit for now. A memory cap needs a measured per-node peak, and every measurement available is a failure-time snapshot, i.e. a lower bound: 4.4 GiB on the busiest node of a variant-0 drill. Sizing the cap off that risks OOM-killing a legitimate container instead of the runaway node. The pid ceiling has no such problem: 8192 against a measured 981 is 8.3x. The value is a static default.env key on purpose. A handler-derived key is absent from .env on a fresh runner, and the topology export step runs before the install step that generates it, so compose interpolation would have failed every swarm job before anything deployed.
