 **问题**: `dashboardApi`（Grafana 仪表盘 CRUD）6 个方法全部为 mock 桩，返回空数组/false。前端 `GrafanaDashboard.tsx` 的"自定义"Tab 有完整 UI 但无法创建/保存仪表盘，面板渲染随机 mock 数据。
 
+### F6: 日志告警引擎 [done]
+
+**问题**: 日志中心有完整查询 UI 和「日志告警」菜单项，但告警规则引擎不支持 `type="log"` 类型规则。用户无法将日志查询转化为告警（如「检测到 ERROR 日志即触发通知」）。日志数据源仅支持 BasicAuth，无法对接需要 Bearer Token 或自定义 Header 的 Loki/ES。
+
+**已完成 (2026-06-28)**:
+- ✅ **后端告警引擎扩展** — `AlertEngine` 新增 `checkLogAlertRules()` 方法：查询 `type="log"` 的告警规则，通过数据源查询 Loki/ES，查询结果 >0 即触发告警事件（含防重复 + 静默检查 + 通知推送）
+- ✅ **自动恢复** — `checkLogAlertRecovery()`：日志告警事件在查询结果归零时自动标记 resolved 并发送恢复通知
+- ✅ **多数据源支持** — `queryLogDataSource()` 支持 Loki（`/loki/api/v1/query_range`）和 Elasticsearch（`_search` + 双时间戳字段兼容 `@timestamp`/`timestamp`）
+- ✅ **日志数据源认证升级** — `LogDataSource` 模型新增 `auth_type`/`token`/`headers` 字段（none/basic/bearer/custom 四种认证），`applyLogDSAuthV2()` 统一认证逻辑，向后兼容旧 `basic_auth` 字段
+- ✅ **AlertEngine 注入 LogDSHandler** — `NewAlertEngine(db, cache, ds)` 新增第三参数，引擎通过 LogDSHandler 加载数据源执行查询
+- ✅ **前端告警规则弹框** — `AlertRuleDialog` 日志类型规则动态加载对应数据源列表（Loki/ES），绑定 `datasource_id`
+- ✅ **从查询创建告警** — `LogAlertFromQueryDialog` 从 mock 桩改为真实 API 调用（`alertApi.createRule`），支持将当前日志查询一键转化为告警规则
+- ✅ **数据源弹框增强** — `LogDatasourceDialog` 支持认证方式选择（无认证/Basic Auth/Bearer Token/自定义 Headers）
+- ✅ **ES 代理错误分类** — `logProxyErrStatus`/`logProxyErrCategory` 将 ES 4xx/5xx 错误映射为标准化响应（含 category 字段供前端区分）
+
+**验收标准**:
+- [x] 可创建 `type="log"` 告警规则，绑定 Loki/ES 数据源 + 查询表达式
+- [x] 引擎周期性执行日志查询，结果 >0 触发告警事件（防重复 + 静默检查）
+- [x] 日志告警可自动恢复（查询结果归零 → resolved + 恢复通知）
+- [x] 日志数据源支持 none/basic/bearer/custom 四种认证方式
+- [x] `AlertEngine` 注入 `LogDSHandler` 不破坏分布式锁（is_leader/distributed 正常）
+- [x] 前端「从查询创建告警」真实调用后端 API（非 mock）
+- [x] `go build` 零错误
