nx_ad_conversion_gate.nx -- GATE (runnable) for ADS-018 privacy-preserving conversion measure. The DELIVERABLE organ: loads the SAME rules + k-anon floor used in production FROM THE SOVEREIGN STORE (adcfg:botrules, adcfg:kanon_k -- pure Nishi, no TSV) and proves the full pipeline (consent-gate -> bot-filter -> aggregate -> k-anon) on baked adversarial controls, parametrized by the configured K. Cannot false-green: each neg control must drop its events, and a small campaign must suppress. happy : consented human conversions summing to >= K -> released count == the exact sum consent: an UNCONSENTED bucket -> contributes 0 (consent-gated) bot : a CONSENTED but bot-class bucket -> contributes 0 (invalid-traffic) k-anon : a consented human campaign with < K total -> SUPPRESSED ("<k", release == -1) Evidence -> knowledge/status/ad_conversion.log (CONVERSIONGATE authored=organ ... verdict=GREEN). license_tier: ORIGINAL
