3A native worker's limits from its manifest (`cpu`, `mem_mb`, `nice`, `background`): their LIMIT_* bits, whether this machine can enforce the CPU and memory caps (`systemd-run --user --scope` probed once), and the check that a spawned process's cgroup v2 really has them (`cpu.max`, `memory.max`, `memory.swap.max`). macOS refuses CPU and memory caps.
