r"""观澜各页面「有没有输出」体检（用户令 2026-09-19）。

背景: 清过产物 + 从 `data/raw` 重算之后, 页面出现"没有输出"的现象。本器**逐页面(含嵌套页)**走一遍
网关入口（默认 http://127.0.0.1:28084）, 对每一页给出:

    HTTP 码 · 字节数 · 判定（有输出 / 空 / 缺件 / 降级 / 报错 / 静态资源）· 证据（页面里那句话）· 疑似原因

覆盖面:
  · 门户 `/`（含内嵌面板是否有内容）· `/healthz` `/api/version` `/ops`
  · `/release/*` 本体发布层（随包件, 清产物后必缺）
  · `/detail/*` 综合详细分析工作台（v2 的 10 个页签取数接口 + 经典嵌套页 `/turbine/<台>` `/problem/<台>/<系统>`）
  · `/cms/*` CMS 振动诊断（总览/逐台页/报告页）
  · `/sim/` `/sim/sys/` `/viewer/` 三个静态模块的入口
  · `release/` 下**随包静态页**（取数单等, 按入口页里出现的链接发现）

判定口径（不猜）: 先看 HTTP 与字节数; 再看**页面自己认账的那句话**（缺件/无产物/加载失败/…）;
JSON 则解析顶层 `err/error/no_products/no_report` 与空数组。每条判定都带证据片段, 便于人工复核。

用法:
    python scripts/pages_sweep.py                 # 控制台摘要 + 写 UTF-8 报告
    python scripts/pages_sweep.py --base http://127.0.0.1:28084
    python scripts/pages_sweep.py --write docs/页面输出体检_v0.1.md
