All 3 source snapshots read from disk (status 200, no fallbacks). source-0.html.gz (TrendForce, 2026-07-03) CONFIRMED: US$1B Guangyuan factory in Henan for T-glass/low-dielectric glass cloth coming online in phases since last year; 1 million meters/month target; first company in China to develop low-dielectric glass cloth for AI servers and 5G base stations; Panasonic Holdings and Resonac Holdings as customers; Nittobo has long dominated the global T-glass market; ChiNext IPO resumed July 2026 three years after previous attempt (attributed to 21jingji within the report); Shengyi 'China's largest producer of copper-clad laminates' ~5.2B yuan Guangdong factory first phase 2028, 1.4B yuan Thailand plant, M9-grade CCL certified for NVIDIA Rubin and GB300; Konfoong 'China's leading producer of sputtering targets' 350M yuan South Korea factory supplying SK hynix and Samsung; Red Avenue HKEX filing Feb 2026; Tokyo Ohka Kogyo and JSR ~80% of global photoresist market. source-1.html.gz (TrendForce, 2025-11-24 deep dive) CONFIRMED verbatim: 'a high-tech offshoot of E-glass', 'doubling T-glass usage in core layers and adding more layers overall', and 'near-monopoly on production-grade T-glass, supplying ... NVIDIA, Microsoft, Google, and Amazon'. source-2.html.gz (TrendForce, 2025-11-28 Nittobo/Nan Ya) CONFIRMED verbatim: 'Nittobo is the world's only company capable of stably mass-producing top-grade T-Glass', 'prevents substrate warpage during advanced packaging ... improving AI chip yield', and Nan Ya 'by 2027 ... responsible for weaving 20% of the specialty glass-fiber fabrics that Nittobo supplies to the global market'.

No hallucinations detected. Every specific (US$1B, Henan, 1M meters/month, 5.2B/1.4B/350M yuan, 2028, M9/Rubin/GB300, ~80% photoresist, 20%-by-2027) traces to the cited snapshot. The article correctly attributes the ~80% figure to photoresist (Tokyo Ohka/JSR) and does NOT conflate it with the separate ~80% high-end sputtering-target figure (JX/Honeywell) that appears in the same source. The Journalist flagged dropping a Nikkei-only '$73bn' figure; confirmed it does NOT appear anywhere in the body. The July 3 2026 anchor is the primary source's publication date and is not misstated in the text. Internal cross-link to the 70%-chip-equipment-target article verified present at src/content/articles/2026-03/06-....
