 ### Overview and live snapshot
 
-[![Multi-provider Memory Space catalog and live relationship snapshot](../assets/screenshots/overview-memory-graph.png)](../assets/screenshots/overview-memory-graph.png)
+[![Snapshot visibility and the live multi-memory relationship graph](../assets/screenshots/overview-memory-graph.png)](../assets/screenshots/overview-memory-graph.png)
+
+Read the live snapshot in two layers from top to bottom:
+
+- Each **Snapshot visibility** card represents one active Memory Space and declares the read surface, projection mode, and observable count its Provider can actually supply. `Real graph`, `Content projection`, and `Query only` are capability boundaries, not quality levels.
+- The **Live multi-memory snapshot** merges those readable results into one relationship graph. Edge colors distinguish space ownership, temporal, semantic, causal, and entity-association links, while Provider and Memory Space labels preserve provenance.
+- The lower left reports total spaces, memories, and entities; the lower right reports currently rendered elements and connections. A value such as `60 / 129` is an interactive rendering window, not missing data.
+- Select a Memory Space, entity, or memory node to inspect its exact context on the right. Natural layout, dragging, and even reset change presentation only; they never rewrite Provider data.
 
 Each card represents a real space. Provider tags use color without duplicating icons inside tags; `Mnemon Native` appears as `mnemon` in the catalog. Click a card to reconnect only that Provider + ID. During reconnect, its state dot becomes an equal-size spinner; no global synchronization runs.

 ### 概览与实时快照

+[![快照可观察范围与多记忆体实时关系图](../assets/screenshots/overview-memory-graph.png)](../assets/screenshots/overview-memory-graph.png)
+
+实时快照从上到下分两层阅读：
+
+- **快照可观察范围**中的每张卡片都对应一个已激活记忆体，并先声明 Provider 真正提供的读取表面、投影方式与可观察数量。`真实关系图`、`内容投影`、`仅查询`是能力边界，不是质量等级；
+- **多记忆体实时快照**把这些可读取结果合并到同一张关系图。边的颜色表示空间归属、时间、语义、因果或实体关联，Provider 与记忆体标签则保留来源；
+- 图谱左下角汇总空间、记忆和实体总数，右下角显示当前渲染的元素与连接。类似 `60 / 129` 表示为保持交互流畅而展示的视窗，不表示其余数据丢失；
+- 点击记忆体、实体或记忆节点后，右侧检查器展示该元素的精确上下文。自然铺开、拖拽和均匀重置只改变布局，不改写 Provider 数据。
 
 每张卡片对应一个真实记忆空间。Provider 标签只用颜色区分，不在标签内重复放图标；`Mnemon Native` 在目录统一展示为 `mnemon`。卡片点击区域用于按需重连当前 Provider + ID，状态灯在重连期间原位变成同尺寸转圈，不触发全量同步。
 
 首次进入概览执行一次全量同步；之后只按需同步。右上角保留“立即同步”，旁边显示距离上次全量同步的时间。
