nx_iot_verify_gate.nx source

1// nx_iot_verify_gate.nx -- SOVEREIGN live publish verifier for the /iot hub 2// control panel (no curl/wget). Does a real HTTPS GET of the just-published 3// https://nishifamily.com/iot.html through the Nishi TLS-1.3 client + real 4// Mozilla CA chain, and asserts: CA store loads, TLS session connects, HTTP 5// 200, and the served body carries this page's markers ("Nishi IoT Hub" + 6// the emitter signature "nx_iot_page"). The "fetch-verify" half of the 7// live-publish loop, done as a Nishi gate (verify via gates, not shell 8// tools). GREEN iff 6/6. Durable knowledge/status/iot_verify_gate.log. 9// license_tier: ORIGINAL (cloned from nx_aw_verify_gate, the reusable verifier) 10import "nx_syscalls.nx" 11import "nx_x509_trust_store.nx" 12import "nx_trust_store_load_from_certdata.nx" 13import "nx_tls13_client_validate_certificate.nx" 14import "nx_tls13_client_session_run.nx" 15import "nx_https_url_for_fetch.nx" 16import "nx_https_url_connect.nx" 17import "nx_https_get.nx" 18import "nx_https_get_complete.nx" 19import "nx_http_response_parse.nx" 20 21func vg_w(s: *u8) -> i64 { var n: i64=0;
