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

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"

WorkMemoryContent

class WorkProject(BaseModel):
    name: str
    description: str | None = None

    available_hours: dict[str, str] = {}       # {"monday": "09:00-18:00"}
