EVENT DOSSIER
On September 7, 2026, the Golden Ruler project released a catalog containing 109 numerical formats, covering FP8, BF16, MXFP4, and micro-scaled formats. The project provides six sets of precisely consistent components, including GF16, MXFP4 elements, BF16, FP8 E4M3/E5M2, and E8M0 block sizes, along with a cross-mapping table for IEEE P3109 v3.2.0. Each set is a self-contained JSON document containing a SHA-256 fingerprint, shared row architecture, and anchor vectors (encoded in 3.0 as cross-set checks). All artifacts are publicly available in the GitHub repository https://github.com/gHashTag/t27, under open source license. The project was cross-verified with ml_dtypes 0.5.4, clearly documenting the differences and interpreting them as allowable normative interpretation gaps.
Golden Ruler 项目发布包含 109 种数值格式的目录，涵盖 FP8、BF16、MXFP4 及微缩放格式。该项目提供六套位精确一致性套件（覆盖 GF16、MXFP4 元素、BF16、FP8 E4M3/E5M2 及 E8M0 块规模），并附带 IEEE P3109 v3.2.0 交叉映射表。每个套件为自包含的 JSON 文档，含 SHA-256 指纹、共享行架构及锚点向量（编码 3.0 作为跨套件校验）。套件与 ml_dtypes 0.5.4 进行交叉验证，差异明确记录并解释为规范允许的解释间隙。所有工件在 https://github.com/gHashTag/t27 公开提供，采用开放许可。
