Abstract ENThis document, produced with the assistance of ChatGPT o3 and GPT-5 Thinking, is released under the Apache 2.0 licence. It is a voluntary defensive publication (prior art) and therefore enters the prior art upon release under the applicable patent statutes: EPC Art. 54(2) (European Patent Convention), French IPC Art. L 611-11 (French Intellectual Property Code), 35 U.S.C. §102(a) (United States Patent Act), Chinese Patent Law Art. 22(5) (中华人民共和国专利法), and Japanese Patent Act Art. 29(1) (特許法). We disclose enabling methods and system architectures for ultra-light diamond lattices in 1g and 0g: orbital CVD with forced pumping, baffles and catalytic inserts; micro-HPHT; binder-jet→diamond conversion; OES–Raman control; HIP densification; NV-based SHM; self-heating B-doped lattices; phononic bandgaps; and embedded heat-pipes. Every proposal is enabling, classified with IPC/CPC codes, and accompanied by timestamp proof (RFC 3161 / FreeTSA).
