nx_reach_probe_cli.nx

nx_reach_probe_cli.nx -- Nishi-native one-shot reach-probe CLI. Compiles to a standalone ELF. Replaces nxc2/bench/nishifamily_external_reach_probe.sh (shell + curl scaffolding). When this binary ships, the shell script reaches SUNSET_READY status per feedback-no-temporary-third-party-scaffolding-when-substrate-arc-exists. Usage (post-deploy): nx_reach_probe_cli https://nishifamily.com/video/ Emits one JSONL line per probe to stdout. Exit code reflects verdict class for CI / cron integration. Composes: nx_reach_probe_now (graduated 2026-05-20) nx_external_reach_probe (sealed NX_REACH_* verdict enum) Per cardinal feedback-substrate-does-heavy-lifting-user-is-partner-not-gate: substrate runs the probe natively; user only invokes the binary + reads JSONL. No curl, no awk, no SSH wrapper, no remote percentile parsing. expect_exit: 0 (default no-arg path; with --arg the exit reflects probe verdict so cron can detect FAIL_TCP_TIMEOUT etc.) license_tier: PUBLIC_NISHI_SUBSTRATE
