a207-policy
A207 统一身份注入 / 权限矩阵 / 状态路径策略包（Plan A 单一事实源）。
13 个 MCP 统一依赖本包，取代原先散落在 M1/M2/M4/M11/M13 的多份权限副本。
用法
from a207_policy import get_caller, enforce_read, enforce_write, LIS_READ_FULL
def get_labs(patient_id: str) -> dict:
caller = get_caller() # 来自 env A207_CALLER，模型碰不到
enforce_read("a207-lis-mcp") # 确定性拒绝越权（fail-closed）
...
- 身份注入：
A207_CALLER环境变量由部署配置写入，模型无法自证（修复 P0-1）。 - 测试：
from a207_policy import set_caller; set_caller("doctor_assistant")。 - 状态路径：
from a207_policy import resolve_state_path; resolve_state_path("followup_store.json")落到A207_DATA_DIR或系统临时目录，避免只读安装目录崩溃（修复 P1-3）。
| 值 | 对应角色 | 能干什么（举例） |
|---|---|---|
doctor_assistant |
医生助手 | 全量读写、写化验、生成报告 |
parent_assistant |
家长助手 | 只看受限视图（没有原始数值） |
nutritionist |
营养师 | 出食谱、算目标 |
child_companion |
患儿伙伴 | 打卡、科普、简单记录 |
orchestrator |
编排层 | 调度所有服务 |
risk_warning |
风险预警 | 发预警通知 |
魔搭社区添加环境变量如下
| 弹窗字段 | 应该填什么 | 详细说明 |
|---|---|---|
| 变量名 | A207_CALLER |
（必填） 必须与 Python 代码中 os.environ.get('A207_CALLER') 的键名完全一致 |
| 描述 | 调用方身份标识 |
写给人类看的备注信息，方便你自己或别人理解这个变量是干嘛的 |
| 详细指引 | （可留空） |
如果有特殊格式要求可以写提示，没有就留空 |
| 是否必填 | 建议开启（拨到必填） | 如果缺少这个变量 Python 代码会报错退出，就开启必填 |
| 类型 | string |
保持默认的 string 即可 |
| 测试值 | parent_assistant |
（最关键！） 魔搭容器运行时真正注入的值，直接填你的实际业务值 |
| 弹窗字段 | 应该填什么 | 详细说明 |
|---|---|---|
| 变量名 | A207_DATA_DIR |
（必填） 必须与 Python 代码中 os.environ.get('A207_DATA_DIR') 的键名完全一致 |
| 描述 | 数据存储路径 |

| 类型 | string |
保持默认的 string 即可 |

但是在云函数条件下，大概率是没有权限写/data目录的，可以改为/tmp/a207
