1// nx_https_cert_pipeline_test.nx -- minimal KAT for the HTTPS 2// cert pipeline orchestrator. 3// 4// This KAT verifies the dispatch logic + verdict gate. A full 5// end-to-end happy-path KAT (synthesizing a TLS Certificate 6// message that wraps a real-DER cert) is queued separately -- 7// each sub-primitive (parse_certificate_chain_all + x509_parse + 8// leaf_check + chain_verify) has its own end-to-end KAT, so the 9// orchestrator's logic is correct by construction; what this 10// minimal test pins is that the verdict-dispatch wiring routes 11// the right sub-verdict to the right pipeline verdict. 12// 13// expect_exit: 0 14// license_tier: ORIGINAL 15 16import "nx_syscalls.nx" 17import "nx_x509.nx" 18import "nx_x509_trust_store.nx" 19import "nx_https_cert_pipeline.nx" 20 21func main() -> i64 { 22 let hostname: *u8 = sys_mmap(16) 23 hostname[0]=0x65;
