nx_printer_ctl_gate.nx

nx_printer_ctl_gate.nx -- gate for the sovereign printer-control organ. Proves the composed capability WITHOUT live hardware (the QIDI is offline per the LAN research probe): pure-logic teeth (dotted-IP parse, the NEVER-BRICK safe-endpoint allowlist) + REAL loopback roundtrips through a fork'd fake Moonraker server (bytes over the real kernel TCP stack via the production nx_mr_*_ipv4 path -- the exact code nx_printer_ctl runs). T1 dotted-IPv4 parse -> correct packed value T2 malformed IPs rejected (fail-closed) T3 NEVER-BRICK: every verb maps ONLY to a safe control endpoint; a raw-gcode / script verb has NO route (cannot reach a firmware-write path) T4 GET /printer/info roundtrip -> HTTP 200 over real loopback T5 POST /printer/emergency_stop roundtrip -> HTTP 200 (Content-Length: 0) license_tier: ORIGINAL No hw writes (Rule 26). expect_exit: 0
