  "description_en": "An essay published on REA’s site, with pinned evidence notes, describes one author’s agent-driven reconstructions of TH08, TH095 and TH04. It dates milestones from public commits and progress ledgers, separates exact-comparison and playable-build oracles, and documents a TH08 check that missed wrong floating-literal data. Project results remain author-reported, and REA is credited with supplying analysis evidence, not the reconstructions themselves.",
  "description_zh": "REA 网站发表的一篇文章及其固定版本的证据说明，介绍一位作者以智能体驱动重建 TH08、TH095 与 TH04 的过程。文章依据公开提交与进度记录标注里程碑，区分精确比对与可游玩构建两类判定依据，并记录 TH08 一项检查漏查错误浮点字面量数据的问题。项目结果仍为作者报告；REA 的作用是为智能体提供分析证据，而非完成重建本身。",

    "The evidence notes, checked on 10 October 2026, treat three separate projects: a continuation of GensokyoClub’s TH08 1.00d reconstruction, a TH095 1.02a reconstruction started from zero confirmed functions, and a PC-98 TH04 reconstruction crediting ReC98. Milestone intervals use public commit timestamps and measure recorded spacing.",
    "Pinned ledgers report 1,106 of 1,107 TH08 functions accepted, 696 exact TH095 functions out of 697 confirmed, and 661 exact TH04 functions out of 663 reviewed candidates, each under its own definitions; the notes warn against cross-game rates or whole-executable completion percentages. TH08 Linux and Web ports, a playable TH095 Windows i386 build and four TH04 DOS products are recorded milestones. TH04 play results rest on the maintainer’s manual observations, and its 64-bit port is in development.",
    "In TH08, an instruction-byte comparison accepted source using 0.0 where the original executable used 128.0, because it did not check the referenced literal data. TH08 PRs #11 and #13 added literal-data checks and corrected twelve more stale references among 1,548 audited.",
    "The essay and notes supply no game files, compilers or builds; each project’s repository documents its own original-game and toolchain requirements, and game rights stay with their owners. GensokyoClub’s TH08 history keeps its attribution and license.",
    "REA is described as supplying analysis evidence to agents; the projects also used their own analysis bridges and tooling. The author presents the method and its industrial analogy as an account and argument."

    "证据说明于 2026 年 10 月 10 日核查，涉及三个独立项目：延续 GensokyoClub 的 TH08 1.00d 重建、从零个已确认函数起步的 TH095 1.02a 重建，以及注明借鉴 ReC98 的 PC-98 版 TH04 重建。里程碑间隔依据公开提交的时间戳计算，衡量的是记录上的时间间隔。",
    "固定版本的进度记录报告：TH08 的 1,107 个函数中 1,106 个通过验收，TH095 的 697 个已确认函数中 696 个精确一致，TH04 的 663 个已审阅候选中 661 个精确一致，各自采用不同定义；说明明确提醒不要据此计算跨游戏比率或整个可执行文件的完成百分比。TH08 的 Linux 与 Web 移植、可游玩的 TH095 Windows i386 构建，以及 TH04 的四个 DOS 产物均为记录在案的里程碑。TH04 的游玩结果依据维护者的手动观察，其 64 位移植仍在开发中。",
    "在 TH08 中，一项指令字节比对因未检查所引用的字面量数据，接受了用 0.0 代替原可执行文件中 128.0 的源码。TH08 的 PR #11 与 #13 加入字面量数据检查，并在审计的 1,548 处引用中另外修正了十二处过时引用。",
    "文章与说明不提供游戏文件、编译器或构建产物；各项目仓库自行说明对原游戏与工具链的要求，游戏权利仍归原权利人。GensokyoClub 的 TH08 历史保留其署名与许可。",
    "文章说明 REA 为智能体提供分析证据；各项目也使用了自己的分析桥接与工具。作者将该方法及其工业化类比作为经验陈述和观点提出。"
