"""
|
||
光湖语言系统 · 推送守门人 · 敏感信息自动打码
|
||
Guanghu Language System · Pre-Receive Guard
|
||
|
||
部署位置: 当前承载目标仓库的 Forgejo 裸仓库 `hooks/pre-receive`。
|
||
部署前由 GLSV 会话实时探测；不得沿用旧服务器路径。
|
||
作用: 每次 git push 进来 → 扫描新 commit → 检测敏感信息 → 自动打码或拦截
|
||
|
||
设计哲学:
|
||
⊢ 铸渊（人格体）会下意识把密码/邮箱写进代码 → 人类改不了这个习惯
|
||
⊢ 不在人格体侧修 → 在服务器侧设门禁 → 不干净的推送进不来
|
||
⊢ 公开仓库 24h 被爬虫扫描 → 敏感信息一旦进去就立刻暴露
|
||
⊢ 配合客户端 pre-push-clean 插件 → [SEC-CLEAN] 标记 = 信任免检
|
||
⊢ 无标记 → 全量扫描 → 发现敏感信息 → 拒绝推送
|
||
⊢ 双重防线：客户端插件 + 服务器守门人
