Abstract
This document, produced with the assistance of GPT-5.2 Thinking and Gemini 3 Reasoning, is released under the Apache License 2.0. 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) (両匡丢氡儡吡嘡丣刡氢), and Japanese Patent Act Art. 29(1) (闘旧避). This defensive disclosure covers blue photonic coatings (cobalt-aluminate spinel pigments and silica matrices) engineered as multi-band dielectric reflectors to reject incident radiative heat during extreme thermal events (wildfires/WUI and critical infrastructure overheating), while enabling passive radiative cooling through the 8–13 µm atmospheric window. It also discloses industrial processes, non-destructive QA metrology, field deployment kits, embedded sensing/edge control, digital twins, federated learning, and supply-chain traceability.
