"""bug-2 修复: 从 v0.1.0 发行包把缺失的 release/如东/ 交付件恢复到 v0.2.0 安装目录。

根因: v0.2.0 包**根本没带** release/如东/ (0.2.0 zip 里 release/ 下只有 viewer/),
而 release/portal.html 的 #documents 区块用 iframe 指向
  http://127.0.0.1:28084/如东/如东治理清单_交付_20260901/02_治理清单/如东_液压系统治理清单_v1.2_2026-09-01.html
该路径由网关 _static() 从 release/ 目录取文件, 文件不在 → 404 {"err":"not found", "path": …},
iframe 里就直接显示那段 JSON。v0.1.0 包里这份交付件是齐的 (76 项), 直接恢复。

(release/如东/ 按 .gitignore 约定不入库 —— 客户交付物只在受保护工作区。)
