# Memory System Design

## Overview

每用户有两条记忆记录（user_type 和 work_type），存储在 `memories` 表的 `content` JSONB 字段中。

## Data Model

### UserMemoryContent

```python
class UserPreferences(BaseModel):
    time_preference: str | None = None           # "上午效率高"
    communication_style: str | None = None      # "简洁直接"
    location_preference: str | None = None       # "喜欢远程工作"
    work_lifestyle: str | None = None           # "早睡早起"

class UserMemoryContent(BaseModel):
    occupation: str | None = None               # 职业
    timezone: str | None = None                # 时区
    language: str | None = None                # 语言偏好
    people: list[str] = []                     # 重要人物
    places: list[str] = []                     # 常去地点
    projects: list[str] = []                    # 个人项目
    preferences: UserPreferences = UserPreferences()
    interests: list[str] = []                   # 兴趣爱好
    avoid_topics: list[str] = []               # 不想讨论的话题
    custom_rules: list[str] = []               # 自定义规则
    recurring_contexts: list[str] = []         # 周期性场景
```

### WorkMemoryContent

```python
class WorkProject(BaseModel):
    name: str
    description: str | None = None
    status: str | None = None                 # "active", "paused"
    key_milestones: list[str] = []            # 关键里程碑

class WorkHabit(BaseModel):
    available_hours: dict[str, str] = {}       # {"monday": "09:00-18:00"}
    deep_work_blocks: list[str] = []           # 深度工作时段
    meeting_preference: str | None = None      # "short", "30min最佳"
    notification_channel: str | None = None    # 首选沟通渠道

class WorkMemoryContent(BaseModel):
    expertise: list[str] = []                   # 专业领域
    preferred_tools: list[str] = []            # 惯用工具
    current_projects: list[WorkProject] = []
    work_habits: WorkHabit = WorkHabit()
    team_members: list[str] = []               # 团队成员
    team_context: str | None = None           # 团队概述
```

## API Endpoints

| PUT | `/api/v1/memories/user` | 创建/更新用户记忆 |
| PUT | `/api/v1/memories/work` | 创建/更新工作记忆 |
| DELETE | `/api/v1/memories/{type}` | 删除指定类型记忆 |

## TaskType支撑关系

| TaskType | Router决策依赖 | Worker执行依赖 |
|----------|---------------|---------------|
| SCHEDULING | timezone, available_hours | current_projects, team_members |
| PLANNING | preferences, work_lifestyle | expertise, work_habits |
