nx_ad_banner_exceed.nx

nx_ad_banner_exceed.nx -- LIB: MEASURED S-class exceed primitives for the banner builder. Organ-graded from LIVE EVIDENCE (measures real emitted bytes), never self-scored. Ladder ABSENT<STUB<BUILT<GATED<MEASURED< EXCEEDS. An axis reaches EXCEEDS only when our MEASURED value is strictly better than a CITED incumbent lower-bound (liar-kill in ex_grade_fewer: equal/worse can NEVER be EXCEEDS). CITED incumbent lower-bound (mainstream display-ad creative, e.g. Google Publisher Tag / DoubleClick): loads the ad-tag library = >=1 THIRD-PARTY SCRIPT; pulls creative + impression/viewability beacons = >=1 EXTERNAL FETCH and >=1 TRACKER (MRC viewability / IAB measurement REQUIRE a measurement script -> tracking implies third-party JS). So incumbent third_party_js>=1, external_fetch>=1, tracker>=1. These are architecture lower-bounds (not fabricated counts); our 0s are MEASURED on the real bytes. Composes nx_ad_serve (as_len). license_tier: ORIGINAL
