nx_adnet_submit.nx

nx_adnet_submit.nx -- LIB: the SELF-SERVE advertiser intake SURFACE (server-rendered, ZERO JS) for the sovereign ad network. Completes the "businesses sign up to advertise" census axis with a real, frontend- testable page: GET renders the form; POST parses the urlencoded body (the DRY nx_http_form_get_field the login route uses), builds a full inventory row, VALIDATES it with the exact same fail-closed validators the serving slot enforces (ass_valid_row: first-party img only, http(s)/path click only, clean slug), and STAGES it to an operator-review journal. STAGED IS NOT LIVE: nothing an advertiser submits ever serves until the operator approves it (ass_approve, a separate operator lane). B2B only; the schema has NO visitor field -> no visitor identity can transit this path by construction. All reflected input is HTML-escaped. license_tier: ORIGINAL
