- schema/迁移: 代理有效期、提醒天数、失败回退配置 + 账号 fallback 来源字段 - service/repo/DTO/handler: CRUD 透传新字段 + 校验 - fallback 目标解析纯函数(链式解析 + 环检测 + 兜底) - SweepExpiredProxies 到期改投账号 + outbox 失效 - ProxyExpiryService 后台到期扫描任务 + wire 注册 - 账号侧手动回切原代理 + fallback 来源徽章/按钮 - 前端: 创建/编辑表单、列表到期徽章、类型/API/i18n - ops 告警: proxy_expired_count / proxy_expiring_soon_count 指标 - 导入导出携带有效期/回退字段(备用按 name 映射) - 补全测试 stub + 集成测试 + review 问题修复
