nx_ad_serve.nx

nx_ad_serve.nx -- LIB: the "Brought to you by" PLACEMENT emitter for the performance ad engine (ADS-004, CALLOUT-004). Emits a static, clean, first-party banner -- the polite old-time-radio sponsorship byline -- with ZERO third-party JavaScript (the headline promise: no surveillance auctions, no third-party scripts, no cross-site profiles). Impression COUNTS ride W5 first-party pageview tracking (PRESENT) + the ADS-019 filter + ADS-007 meter; this organ's job is the clean placement itself. DEFENSIVE AT THE BOUNDARY (rule 12): the sponsor's business name + banner text are EXTERNAL input, so they are HTML-escaped before emission -- a sponsor named "<script>..." cannot inject script. The emitted markup uses single-quoted attributes + inline first-party styling only; NO <script>, <iframe>, src=, <object>, <embed> -- and `as_has_thirdparty_js` proves it (the gate also proves that detector FIRES on a planted third-party tag, so GREEN means "proven clean", not "assumed"). license_tier: ORIGINAL
