nx_onsite_frontier_fetch.nx

nx_onsite_frontier_fetch.nx -- SOVEREIGN onsite-search S-CLASS FRONTIER research fetch. Rung S-RESEARCH-2 of the onsite-search arc: the 7-axis exceed census proved we are PARITY on the lexical core + EXCEEDS on sovereignty, but BEHIND on the neural/semantic rung -- and that rung is what blocks a real, full S-class. The operator's directive: find out, HARDWARE-RUNG-UP, what we need to build to close it. Global Rule 4 (no assumptions): every rung + every new census cell must cite a REAL fetch, not memory. Reuses the team's OWN proven sovereign HTTPS stack (nx_tls13_client_session_run + nx_https_get_complete; no browser/node/curl), validated against the real Mozilla CA store -- the IDENTICAL path proven live in nx_onsite_research_fetch (the srch_* corpus, 2026-06-16).
