nx_mesh_hostagent.nx

nx_mesh_hostagent.nx -- WORKER MESH: the AUTONOMOUS host-agent that makes autoscale HANDS-OFF. It runs on the worker host, and each tick it: reads DEMAND, PROBES the worker for warmth (bounded, ~1s), DECIDES via the autoscale policy (SPAWN/SERVE/HOLD/REAP), and ACTUATES -- fork+execve the worker on SPAWN, nx_kill+wait4 on REAP. No human in the loop: the organ physically starts and stops the worker process as demand comes and goes. On NishiOS this forks the container natively; the exact same fork/kill lifecycle is exercised here against a real child process. CLI: (no args) -> self-test GATE (the decision policy) demo <workerpath> <port> -> run the autonomous cold->SPAWN->SERVE->(idle)->REAP->cold cycle, forking and killing a REAL worker child on a built-in demand schedule (proves the loop) Actions: 0 HOLD 1 SPAWN 2 SERVE 3 REAP. license_tier: ORIGINAL
