nx_autorun_poke.nx

nx_autorun_poke.nx -- the EVENT trigger for nx_autorun_daemon (event-driven mode). Writes ONE byte to the daemon's FIFO -> wakes it for exactly one re-prove beat. Non-blocking: if no daemon is listening (no reader on the FIFO) the O_NONBLOCK open returns ENXIO and the poke reports it instead of hanging. Any producer -- a git post-commit hook, nx_attempt_loop after authoring, or a human -- calls this: it is the ecosystem's "something changed, re-prove the rungs" signal, replacing the old 6h clock. Sovereign: syscalls only, no .sh. license_tier: ORIGINAL
