"""⑤.7 配置预览渲染引擎 —— issue #65 / PRD ⑤.7。
|
|||
|
|
|
|||
|
|
配置台让实施工程师"边配边看"：改完布局/告警/查询配置后，立即在预览区看到
|
|||
|
|
驾驶舱会变成什么样、告警会怎么触发、NL 查询会怎么响应——**不必发布到生产
|
|||
|
|
就能确认效果**。本模块是预览区的渲染后端，把 ``ConfigStore`` 里的配置渲染
|
|||
|
|
为**结构化的预览片段**（dict/JSON），对齐 ``iAOP-cockpit-layout-v1`` 的
|
|||
|
|
widget 类型与既有驾驶舱资产（resin cockpit）。
|
|||
|
|
|
|||
|
|
三类预览：
|
|||
|
|
|
|||
|
|
- **布局预览**（``render_layout_preview``）：把 layout widget 列表渲染为
|
|||
|
|
带占位网格坐标的 widget 描述（type/bind/metric/description + x/y/w/h），
|
|||
|
|
计算网格占用率（发现越界/重叠）；
|
|||
|
|
- **告警预览**（``render_alarm_preview``）：把告警规则（point + 阈值 + 级别）
|
|||
|
|
渲染为"当 X 超过 Y 时，触发 级别 告警"的可读条目 + 模拟评估（给定当前值
|
|||
|
|
是否触发）；
|
|||
|
|
- **NL 查询预览**（``render_nl_query_preview``）：把 NL 查询模板渲染为示例
|
|||
|
|
问答对（模板 × 示例槽位 → 渲染后的问句 + 预期数据来源）。
|
|||
|
|
|
|||
|
|
预览是**只读、无副作用**的——只读配置、产出结构化输出，不改任何状态，
|
|||
|
|
对齐 PRD「预演不污染生产」。
|
|||
|
|
|
|||
|
|
零运行时依赖：仅用 dataclass / Enum / 标准库。
