+# Work Log - 修复系统消息查看 500（2026-06-16）
+
+- 背景：
+  - `/api/v1/system-messages/me` 返回系统消息列表时，对 SQLAlchemy ORM 对象执行 `SystemMessagePublic.model_validate()`，Pydantic v2 未启用属性读取，导致 500。
+
+- 本次处理：
+  - 为 `SystemMessagePublic` 增加 `ConfigDict(from_attributes=True)`，允许响应 schema 从 ORM/属性对象读取字段。
+  - 新增系统消息 schema 回归测试，覆盖属性对象序列化路径。
+
+- 验证：
+  - 基线：未启用 `from_attributes` 时，属性对象 `model_validate` 复现 Pydantic `model_type` 校验失败。
+  - 修改后：属性对象 `model_validate` 可正常输出。
+  - `pytest api/tests/test_system_message_schema.py` 通过。
+
+- 风险与关注点：
+  - 改动仅影响系统消息公开响应 schema 的序列化方式，不改变接口字段、数据库结构或查询逻辑。
