    "The pinned workspace identifies version 0.7.0 and declares Rust 1.90+ with Cargo. Browser builds use Trunk and wasm32-unknown-unknown; native Linux CI lists X11/Wayland, GTK, fontconfig/FreeType and graphics dependencies. Fonts and input workbooks are separate.",
    "Reviewed XLSX tests construct workbooks and OOXML packages, compare modeled values after writing and reading, and check selected unmodeled parts and relationships.",
    "Calculation tests use expected values for selected formulas, dependency changes and spilled arrays. The dated assessment against Excel for Mac 16.113.4 records the absence of Excel-computed conformance oracles.",
    "The project remains alpha. File fidelity, advanced workflows, performance and ecosystem compatibility remain bounded, and the README documents graphics-driver startup issues.",
    "Code is MIT OR Apache-2.0 with NOTICE obligations; optional fonts and ArtCraft branding have separate terms. Published modified versions must remove the ArtCraft marks, except contribution-only forks. Clean-room is the authors’ characterization."

    "所审阅 XLSX 测试构造工作簿与 OOXML 包，比较写入再读取后的已建模值，并检查选定的未建模部件及关系。",
    "计算测试使用预期值检查选定公式、依赖变化和溢出数组。针对 Excel for Mac 16.113.4 的注明日期评估记录缺少以 Excel 计算结果为基准的一致性测试。",
    "项目仍处于 alpha；文件保真度、高级流程、性能与生态兼容性仍有边界，README 还记录图形驱动启动问题。",
    "代码采用 MIT OR Apache-2.0，并有 NOTICE 义务；可选字体与 ArtCraft 品牌另有条款。公开发布修改版须移除 ArtCraft 标识，仅用于向上游提议改动的 fork 除外。净室只是作者的说法。"
