+## Collection 名称统一为 mem0_v4_shared (2026-02-27)
+
+### 背景
+之前配置中存在 Collection 名称不一致问题：
+- 代码实际使用：`mem0_global_v4`
+- 用户指定/文档记录：`mem0_v4_shared`（陈医生和张大师共用）
+
+### 修改决策
+王院长明确指示：所有 Collection 统一使用 `mem0_v4_shared`，不得随意修改关键配置。
+
+### 修改文件列表
+1. `skills/mem0-integration/mem0_client.py`
+2. `skills/mem0-integration/config.yaml`
+3. `skills/mem0-integration/skill.json`
+4. `skills/mem0-integration/config-life.yaml`
+5. `agents/life-agent.json`
+6. `agents/life-workspace/skills/mem0-integration/config.yaml`
+7. `docs/SYSTEM_ARCHITECTURE.md`
+
+### 验证结果
+- ✅ Gateway 重启成功 (systemd 服务正常)
+- ✅ Qdrant Collection `mem0_v4_shared` 已创建
+- ✅ 向量维度：1024 (text-embedding-v4)
+- ✅ 距离度量：Cosine
+- ✅ 元数据索引：user_id, agent_id, actor_id, run_id
+- ✅ Embedding 计费通道：Bailian 标准计费
+
+### 操作日志
+`/root/.openclaw/workspace/logs/operations/2026-02-27-08-55-00-unify-collection-name.log`
+
+### 重要原则
+- 关键配置（Collection 名称、Embedding 模型、计费通道）修改必须经过用户确认
+- 所有 Agent 共享同一 Collection，通过 `metadata.agent_id` 实现逻辑隔离
