nx_adnet_invoice.nx -- LIB: the BILLING PIPELINE for the sovereign ad network (debt 1785513943). THE GAP IT CLOSED: nx_adnet_bill held correct CPM/CPC math that NOTHING ever called -- grep found zero production callers, only its own gate. The network served slots and journalled served/viewable/click events, but no organ ever read those journals, applied a rate, or produced an invoice, so no advertiser could be charged at all. Correct math nobody calls is not a billing system. This COMPOSES (rule 22) the already-gated parts rather than re-implementing them: ad_event_count for the per-AD counts, anb_invoice_line_v for the viewable-basis money math. It adds exactly one thing -- the RATE CARD, and the loop that joins rates to measured events. RATES ARE DATA, NEVER CODE (rule 11): knowledge/status/adnet_rates.conf, one row per ad: <ad_id>\t<cpm_milli>\t<cpc_milli>\t<cap_milli> ('#' comment rows ignored) DELIBERATELY NOT under sites/ -- a rate card is commercially sensitive and /synth/ is publicly served. HONEST-BILLING LAW: an ad with NO rate row is REFUSED, never defaulted to zero and never guessed. A missing price and a price of zero are different facts and must not collapse into the same invoice line. license_tier: ORIGINAL
