"""config.py —— 环境变量驱动的 BFF 配置（pydantic-settings）。
|

|
|
|
|||
|
|
全部键见 backend/.env.example。凭据类键（Neo4j）只存在于本进程，
|
|||
|
|
**绝不下发到浏览器**（不进入任何 API 响应）。
|
|||
|
|
|
|||
|
|
上游拓扑与默认值依据 docs/DISCOVERY.md：
|
|||
|
|
- QA 7920：`/api/v1/qa-v1-1-73`（DISCOVERY §4）
|
|||
|
|
- RAG 8000（Methodology API，DISCOVERY §3）/ ragAlt 7900（protected 容器，§3.7）
|
|||
|
|
- Neo4j 候选顺序：18788（direct，首选）→ 19788（normalized）→ 17687（protected，空库）
|
|||
|
|
凭据见 DISCOVERY §2.1，可由 BFF_NEO4J_* 环境变量覆盖（测试/部署）。
