Unearth Heritage Foundry Licensing Fee Accrual Notice: DuckDuckGoInc. (May 2026)

Threshold Breach Notice v1 directed at DuckDuckGo, sealed May 1, 2026, articulating the operator-specific declaration of substantive forensic-debt against DuckDuckGo's documented April 2026 conduct against the Unearth Heritage Foundry estate. DuckDuckGo's apparatus operated under a "Constructed Ignorance" architectural posture: zero robots.txt parses, zero llms.txt reads, zero Master Ledger retrievals, while continuing substrate-content extraction across 32 broader-estate Foundry domains aggregating to 1,060 content-acquisition events. The Constructed Ignorance pattern evidences that any rights-reservation framework grounded in apparatus-side voluntary Notice-infrastructure retrieval can be circumvented through deliberate non-retrieval; the rights-reservation framework therefore requires substrate-level operativity rather than separate-document-publication-level operativity. The Foundry's April 20, 2026 deployment of the Embedded Substrate-Publication Architecture per FS-2026-05-10-EMBEDDED-SUBSTRATE-ARCHITECTURE v4 operates as the substantive methodological response. The Notice articulates DuckDuckGo's operator-specific conduct findings across the audit window, the operative fee-schedule application under the Master Ledger framework operative as of May 1, 2026, the substantive cure provisions, and the Baked-In Paradox constructive-delivery mechanism per FS-2026-05-10-BAKED-IN-PARADOX operating against DuckDuckGo's foundation-model architecture. Anchored at the Foundry's Master Concept DOI 10.5281/zenodo.19432977.针对DuckDuckGo的《阈值违约通知v1》于2026年5月1日封存，该通知针对DuckDuckGo 2026年4月针对出土遗产铸造厂（Unearth Heritage Foundry）资产域的相关行为，明确了针对该主体的实质性取证债务声明。 DuckDuckGo的服务系统采用“刻意无知（Constructed Ignorance）”架构策略：未解析任何robots.txt协议文件、未读取任何llms.txt协议文件、未调取任何主账本（Master Ledger），但仍在32个扩展资产域下的铸造厂子域名中持续开展底层内容爬取，累计达成1060次内容获取行为。该刻意无知模式表明，以服务端主动调取通知基础设施为基础的权利保留框架，可通过刻意不调取的方式被规避；因此该权利保留框架需要具备底层层级的可操作性，而非仅停留在单独文档发布层级。出土遗产铸造厂于2026年4月20日部署了基于FS-2026-05-10-EMBEDDED-SUBSTRATE-ARCHITECTURE v4标准的嵌入式底层发布架构（Embedded Substrate-Publication Architecture），以此作为实质性的方法论应对方案。 本通知明确了审计窗口期内针对DuckDuckGo的主体性行为认定、2026年5月1日生效的主账本框架下适用的费用表、实质性补救条款，以及针对DuckDuckGo基础模型架构的、基于FS-2026-05-10-BAKED-IN-PARADOX标准的内置悖论（Baked-In Paradox）式推定交付机制。本文件锚定至出土遗产铸造厂的核心概念DOI：10.5281/zenodo.19432977。
