+# MonitorMapChrome Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** 抽出地图 chrome（toolbar/legend/scale）。
+
+**Spec:** `docs/superpowers/specs/2026-08-28-monitor-map-chrome-design.md`
+
+### Task 1
+
+Create `MonitorMapChrome.vue`；MonitorView：
+
+```vue
+<div class="map-panel">
+  <MonitorMapChrome
+    :map-mode="mapMode"
+    :scale-text="mapScaleText"
+    @set-map-mode="setMapMode"
+    @fit-all="fitAll"
+  >
+    <CommandProgressFloat ... />
+  </MonitorMapChrome>
+</div>
+```
+
+或 chrome 不包 slot、同级放置 float 也可——保持 float 仍在 `.map-panel` 内。
+
+Commit: `refactor: 抽取 MonitorMapChrome 地图工具条图例`
+
+### Task 2 冒烟
+
+卫星/地图切换 class active；fit 按钮可点；比例尺文案存在。
+
+## 约束
+
+跳过全量测试；Main 可冒烟

+# MonitorMapChrome 设计
+
+## 目标
+
+抽出 map-panel 内工具条 / 图例 / 比例尺为 `MonitorMapChrome.vue`。`CommandProgressFloat` 仍由页面放在 map-panel 内（或 chrome 提供 default slot）。
+
+## 契约
+
+**Props:** `mapMode` (`satellite`|`street`) · `scaleText`
+
+**Emits:** `update:mapMode` 或 `set-map-mode` · `fit-all`
+
+**Slot:** default — 进度浮层等叠加层
+
+地图实例 / `setMapMode` / `fitAll` / `mapScaleText` 计算留页面。
+
+## 实现
+
+1. `src/components/MonitorMapChrome.vue`
+2. MonitorView map-panel 改为 chrome + CommandProgressFloat slot/子节点
+3. Commit: `refactor: 抽取 MonitorMapChrome 地图工具条图例`
+
+## 约束
+
+不改 mapHelper；精确 git add；中文 commit
