nx_adnet_selfserve.nx

nx_adnet_selfserve.nx -- LIB: self-serve advertiser intake for the sovereign ad network. An advertiser submits a full inventory row (id/advertiser/img/clickurl/section/weight -- the exact nx_adnet contract); the row is VALIDATED with the same fail-closed rules the serving slot enforces (first-party img only, http(s)/path click only, clean id) and then appended to a STAGED submissions journal. STAGED IS NOT LIVE: nothing an advertiser submits ever serves until the operator approves it into the live inventory conf (ass_approve appends a validated staged row there -- an operator action, never automatic). B2B only; the schema HAS NO VISITOR FIELD -- no visitor identity can transit this path by construction. license_tier: ORIGINAL
