nx_motion_smoke.nx -- DIAGNOSE AND GATE THE /motion DAEMON'S LISTEN (2026-09-06, rung MO14 core). The deploy health probe reports NEVER-LISTENED but hides the daemon's OWN stderr, and a daemon cannot be nx_job_run (jlb_denied) to capture it. This oneshot forks the daemon BINARY on a throwaway port with a bounded watchdog (gk_run_capture_ms kills it at the deadline), captures its stdout+stderr, and reports whether it bound -- so 'does the daemon listen' becomes a runnable, gateable check instead of a deploy gamble. nx_motion_smoke [elf] [port] elf defaults to ./nx_motion_serve.elf.new, port to a throwaway 28139 exit: 0 LISTENED | 3 BIND-FAILED (port taken / bind refused) | 4 NO-OUTPUT (crashed before printing) Its name carries no control-plane stem, so the async launcher admits it; it binds nothing itself. license_tier: ORIGINAL expect_exit: 0
